GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA
Everyone is permitted to copy and distribute verbatim copies of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your freedom to share and change it. By contrast, the GNU General Public License is intended to guarantee your freedom to share and change free software--to make sure the software is free for all its users. This General Public License applies to most of the Free Software Foundation's software and to any other program whose authors commit to using it. (Some other Free Software Foundation software is covered by the GNU Lesser General Public License instead.) You can apply it to your programs, too.
When we speak of free software, we are referring to freedom, not price. Our General Public Licenses are designed to make sure that you have the freedom to distribute copies of free software (and charge for this service if you wish), that you receive source code or can get it if you want it, that you can change the software or use pieces of it in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid anyone to deny you these rights or to ask you to surrender the rights. These restrictions translate to certain responsibilities for you if you distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether gratis or for a fee, you must give the recipients all the rights that you have. You must make sure that they, too, receive or can get the source code. And you must show them these terms so they know their rights.
We protect your rights with two steps: (1) copyright the software, and (2) offer you this license which gives you legal permission to copy, distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain that everyone understands that there is no warranty for this free software. If the software is modified by someone else and passed on, we want its recipients to know that what they have is not the original, so that any problems introduced by others will not reflect on the original authors' reputations.
Finally, any free program is threatened constantly by software patents. We wish to avoid the danger that redistributors of a free program will individually obtain patent licenses, in effect making the program proprietary. To prevent this, we have made it clear that any patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and modification follow.
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains a notice placed by the copyright holder saying it may be distributed under the terms of this General Public License. The "Program", below, refers to any such program or work, and a "work based on the Program" means either the Program or any derivative work under copyright law: that is to say, a work containing the Program or a portion of it, either verbatim or with modifications and/or translated into another language. (Hereinafter, translation is included without limitation in the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not covered by this License; they are outside its scope. The act of running the Program is not restricted, and the output from the Program is covered only if its contents constitute a work based on the Program (independent of having been made by running the Program). Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice and disclaimer of warranty; keep intact all the notices that refer to this License and to the absence of any warranty; and give any other recipients of the Program a copy of this License along with the Program.
You may charge a fee for the physical act of transferring a copy, and you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion of it, thus forming a work based on the Program, and copy and distribute such modifications or work under the terms of Section 1 above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in whole or in part contains or is derived from the Program or any part thereof, to be licensed as a whole at no charge to all third parties under the terms of this License.
c) If the modified program normally reads commands interactively when run, you must cause it, when started running for such interactive use in the most ordinary way, to print or display an announcement including an appropriate copyright notice and a notice that there is no warranty (or else, saying that you provide a warranty) and that users may redistribute the program under these conditions, and telling the user how to view a copy of this License. (Exception: if the Program itself is interactive but does not normally print such an announcement, your work based on the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If identifiable sections of that work are not derived from the Program, and can be reasonably considered independent and separate works in themselves, then this License, and its terms, do not apply to those sections when you distribute them as separate works. But when you distribute the same sections as part of a whole which is a work based on the Program, the distribution of the whole must be on the terms of this License, whose permissions for other licensees extend to the entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest your rights to work written entirely by you; rather, the intent is to exercise the right to control the distribution of derivative or collective works based on the Program.
In addition, mere aggregation of another work not based on the Program with the Program (or with a work based on the Program) on a volume of a storage or distribution medium does not bring the other work under the scope of this License.
3. You may copy and distribute the Program (or a work based on it, under Section 2) in object code or executable form under the terms of Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable source code, which must be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three years, to give any third party, for a charge no more than your cost of physically performing source distribution, a complete machine-readable copy of the corresponding source code, to be distributed under the terms of Sections 1 and 2 above on a medium customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer to distribute corresponding source code. (This alternative is allowed only for noncommercial distribution and only if you received the program in object code or executable form with such an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for making modifications to it. For an executable work, complete source code means all the source code for all modules it contains, plus any associated interface definition files, plus the scripts used to control compilation and installation of the executable. However, as a special exception, the source code distributed need not include anything that is normally distributed (in either source or binary form) with the major components (compiler, kernel, and so on) of the operating system on which the executable runs, unless that component itself accompanies the executable.
If distribution of executable or object code is made by offering access to copy from a designated place, then offering equivalent access to copy the source code from the same place counts as distribution of the source code, even though third parties are not compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program except as expressly provided under this License. Any attempt otherwise to copy, modify, sublicense or distribute the Program is void, and will automatically terminate your rights under this License. However, parties who have received copies, or rights, from you under this License will not have their licenses terminated so long as such parties remain in full compliance.
5. You are not required to accept this License, since you have not signed it. However, nothing else grants you permission to modify or distribute the Program or its derivative works. These actions are prohibited by law if you do not accept this License. Therefore, by modifying or distributing the Program (or any work based on the Program), you indicate your acceptance of this License to do so, and all its terms and conditions for copying, distributing or modifying the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the Program), the recipient automatically receives a license from the original licensor to copy, distribute or modify the Program subject to these terms and conditions. You may not impose any further restrictions on the recipients' exercise of the rights granted herein. You are not responsible for enforcing compliance by third parties to this License.
7. If, as a consequence of a court judgment or allegation of patent infringement or for any other reason (not limited to patent issues), conditions are imposed on you (whether by court order, agreement or otherwise) that contradict the conditions of this License, they do not excuse you from the conditions of this License. If you cannot distribute so as to satisfy simultaneously your obligations under this License and any other pertinent obligations, then as a consequence you may not distribute the Program at all. For example, if a patent license would not permit royalty-free redistribution of the Program by all those who receive copies directly or indirectly through you, then the only way you could satisfy both it and this License would be to refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under any particular circumstance, the balance of the section is intended to apply and the section as a whole is intended to apply in other circumstances.
It is not the purpose of this section to induce you to infringe any patents or other property right claims or to contest validity of any such claims; this section has the sole purpose of protecting the integrity of the free software distribution system, which is implemented by public license practices. Many people have made generous contributions to the wide range of software distributed through that system in reliance on consistent application of that system; it is up to the author/donor to decide if he or she is willing to distribute software through any other system and a licensee cannot impose that choice.
This section is intended to make thoroughly clear what is believed to be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in certain countries either by patents or by copyrighted interfaces, the original copyright holder who places the Program under this License may add an explicit geographical distribution limitation excluding those countries, so that distribution is permitted only in or among countries not thus excluded. In such case, this License incorporates the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions of the General Public License from time to time. Such new versions will be similar in spirit to the present version, but may differ in detail to address new problems or concerns.
Each version is given a distinguishing version number. If the Program specifies a version number of this License which applies to it and "any later version", you have the option of following the terms and conditions either of that version or of any later version published by the Free Software Foundation. If the Program does not specify a version number of this License, you may choose any version ever published by the Free Software Foundation.
10. If you wish to incorporate parts of the Program into other free programs whose distribution conditions are different, write to the author to ask for permission. For software which is copyrighted by the Free Software Foundation, write to the Free Software Foundation; we sometimes make exceptions for this. Our decision will be guided by the two goals of preserving the free status of all derivatives of our free software and of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest possible use to the public, the best way to achieve this is to make it free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest to attach them to the start of each source file to most effectively convey the exclusion of warranty; and each file should have at least the "copyright" line and a pointer to where the full notice is found.
one line to give the program's name and an idea of what it does. Copyright (C) yyyy name of author
This program is free software; you can redistribute it and/or modify it under the terms of the GNU General Public License as published by the Free Software Foundation; either version 2 of the License, or (at your option) any later version.
This program is distributed in the hope that it will be useful, but WITHOUT ANY WARRANTY; without even the implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the GNU General Public License for more details.
You should have received a copy of the GNU General Public License along with this program; if not, write to the Free Software Foundation, Inc., 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301, USA. Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) year name of author Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'. This is free software, and you are welcome to redistribute it under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate parts of the General Public License. Of course, the commands you use may be called something other than `show w' and `show c'; they could even be mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your school, if any, to sign a "copyright disclaimer" for the program, if necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program `Gnomovision' (which makes passes at compilers) written by James Hacker.

```
## Building the React Application
### Step 1: Install Node.js Dependencies
Create a `package.json` file in the plugin root directory:
```json
{
"name": "wpforms-mailjet-automation",
"version": "1.0.0",
"description": "WPForms to Mailjet automation plugin",
"scripts": {
"build": "wp-scripts build assets/src/wizard/App.jsx --output-path=admin/js",
"start": "wp-scripts start assets/src/wizard/App.jsx --output-path=admin/js"
},
"devDependencies": {
"@wordpress/scripts": "^26.0.0"
},
"dependencies": {
"@wordpress/element": "^5.0.0",
"@wordpress/components": "^25.0.0",
"@wordpress/i18n": "^4.0.0"
}
}
```
Then run:
```bash
npm install
```
### Step 2: Build the React Bundle
Run the build command:
```bash
npm run build
```
This will compile all React components into `admin/js/wpfmj-wizard.js` and generate `admin/js/wpfmj-wizard.asset.php` with dependency information.
### Step 3: Development Mode (Optional)
For development with hot reload:
```bash
npm run start
```

1. Upload the entire `wpforms-mailjet-automation` folder to `/wp-content/plugins/`
2. Activate the plugin through the 'Plugins' menu in WordPress
3. Ensure WPForms is installed and activated
4. (Optional) Copy `wpfmj-config-sample.php` to `wpfmj-config.php` and customize settings
5. Navigate to 'Mailjet Automations' in the WordPress admin menu

- [ ] Capability checks enforced
- [ ] API credentials properly encrypted
## Common Issues and Solutions
### Issue: React bundle not loading
**Solution:** Run `npm run build` to generate the JavaScript bundle
### Issue: "WPForms required" error
**Solution:** Install and activate WPForms plugin
### Issue: API connection fails
**Solution:** Verify API credentials in Mailjet account under Account Settings > REST API
### Issue: Automation not triggering
**Solution:** Check that automation status is "Active" (not "Paused")
### Issue: Missing form fields
**Solution:** Ensure the selected form has been saved with fields in WPForms

# WPForms to Mailjet Automation - Configuration Guide
## Overview
This plugin supports extensive customization through WordPress filters. You can modify settings without touching core plugin files, ensuring your customizations survive plugin updates.
## Quick Start
1. **Copy the sample configuration file:**
```bash
cp wpfmj-config-sample.php wpfmj-config.php
```
2. **Edit `wpfmj-config.php`** with your preferred settings
3. **Save and upload** - Settings take effect immediately
The `wpfmj-config.php` file is automatically loaded by the plugin and is excluded from version control.
---
## Available Configuration Options
### 1. Error Log Retention Period
**Filter**: `wpfmj_error_log_retention_days`
**Default**: 90 days
**Range**: 7-365 days
**Type**: Integer
Controls how long resolved error logs are kept before automatic deletion.
```php
add_filter('wpfmj_error_log_retention_days', function($days) {
return 180; // Keep for 6 months
});
```
**Considerations:**
- **Shorter periods (7-30 days)**: Saves database space, good for high-volume sites
- **Longer periods (90-365 days)**: Better for audit trails and trend analysis
- **Optimal**: 90 days balances storage and historical data
---
### 2. API Rate Limit
**Filter**: `wpfmj_api_rate_limit`
**Default**: 60 requests/minute
**Range**: 10-300 requests/minute
**Type**: Integer
Sets the maximum Mailjet API requests per minute per API key.
```php
add_filter('wpfmj_api_rate_limit', function($limit) {
return 120; // Double the default
});
```
**Considerations:**
- **Lower limits (10-30)**: More conservative, prevents rate limit errors
- **Default (60)**: Balanced for most sites
- **Higher limits (120-300)**: For high-traffic sites, but monitor closely
- **Mailjet limit**: 300 requests/minute maximum
⚠️ **Warning**: Setting too high may cause Mailjet to reject requests.
---
### 3. Maximum Retry Attempts
**Filter**: `wpfmj_max_retry_attempts`
**Default**: 3 attempts
**Range**: 1-5 attempts
**Type**: Integer
Number of retry attempts for failed API calls.
```php
add_filter('wpfmj_max_retry_attempts', function($attempts) {
return 5; // Maximum persistence
});
```
**Retry Timing:**
- Attempt 1: Immediate
- Attempt 2: After 1 second
- Attempt 3: After 2 seconds
- Attempt 4: After 4 seconds
- Attempt 5: After 8 seconds
**Considerations:**
- **1 attempt**: Fast failure, good for testing
- **3 attempts (default)**: Balanced approach
- **5 attempts**: Maximum reliability, but slower failure detection
---
### 4. Email Notification Recipients
**Filter**: `wpfmj_failure_notification_emails`
**Default**: WordPress admin email
**Type**: Array of email addresses
Customize who receives failure notifications.
```php
add_filter('wpfmj_failure_notification_emails', function($emails) {
return array(
get_option('admin_email'),
'developer@example.com',
'support@example.com',
'monitoring@example.com'
);
});
```
**Use Cases:**
- **Development team**: Add developer emails
- **Support team**: Add support desk email
- **Monitoring**: Integrate with ticketing systems
- **Multiple admins**: Ensure redundancy
---
### 5. Disable Email Notifications
**Filter**: `wpfmj_disable_failure_notifications`
**Default**: false (notifications enabled)
**Type**: Boolean
Completely disable email notifications.
```php
add_filter('wpfmj_disable_failure_notifications', function($disabled) {
return true; // Disable all emails
});
```
**When to disable:**
- Using external monitoring tools
- High-volume sites with frequent transient errors
- During development/testing
⚠️ **Note**: Errors are still logged in the database even when notifications are disabled.
---
### 6. Encryption Method
**Filter**: `wpfmj_encryption_method`
**Default**: AES-256-CBC
**Type**: String
Change the encryption algorithm for API credentials.
```php
add_filter('wpfmj_encryption_method', function($method) {
return 'AES-256-GCM'; // More modern algorithm
});
```
**Available Methods:**
- `AES-256-CBC` (default, widely compatible)
- `AES-256-GCM` (modern, authenticated encryption)
- `AES-192-CBC`
- See `openssl_get_cipher_methods()` for full list
⚠️ **CRITICAL WARNING**:
- **Only change BEFORE storing any credentials**
- Changing after credentials are stored will make them unreadable
- Requires re-entering all API keys if changed later
- Test thoroughly after changing
---
### 7. Debug Mode
**Filter**: `wpfmj_debug_mode`
**Default**: false
**Type**: Boolean
Enable verbose logging for troubleshooting.
```php
add_filter('wpfmj_debug_mode', function($debug) {
return true; // Enable debug logging
});
```
**What gets logged:**
- API request details
- Retry attempts with timestamps
- Decryption operations
- Rate limit hits
- Form processing steps
**Important**:
- Only enable when troubleshooting
- Logs may contain sensitive information
- Disable in production unless necessary
- Check `wp-content/debug.log`
---
### 8. Cleanup Cron Schedule
**Filter**: `wpfmj_cleanup_schedule`
**Default**: weekly
**Type**: String
Change how often error log cleanup runs.
```php
add_filter('wpfmj_cleanup_schedule', function($schedule) {
return 'daily'; // Clean up more frequently
});
```
**Available Schedules:**
- `hourly` - Every hour
- `twicedaily` - Twice per day
- `daily` - Once per day
- `weekly` - Once per week (default)
**Considerations:**
- High-volume sites: Use `daily` or `twicedaily`
- Low-volume sites: `weekly` is sufficient
- More frequent = less database bloat
---
## Advanced Configuration Examples
### Example 1: High-Traffic Site
```php
<?php
// wpfmj-config.php for high-traffic e-commerce site
// Aggressive cleanup to manage database size
add_filter('wpfmj_error_log_retention_days', function($days) {
return 30; // Only 30 days
});
// Higher rate limit for busy periods
add_filter('wpfmj_api_rate_limit', function($limit) {
return 120;
});
// More frequent cleanup
add_filter('wpfmj_cleanup_schedule', function($schedule) {
return 'daily';
});
// Multiple notification recipients
add_filter('wpfmj_failure_notification_emails', function($emails) {
return array(
'dev-team@example.com',
'ops@example.com'
);
});
```
### Example 2: Development Environment
```php
<?php
// wpfmj-config.php for staging/dev environment
// Disable email spam during testing
add_filter('wpfmj_disable_failure_notifications', function($disabled) {
return true;
});
// Enable debug mode
add_filter('wpfmj_debug_mode', function($debug) {
return true;
});
// Lower retry attempts for faster testing
add_filter('wpfmj_max_retry_attempts', function($attempts) {
return 1; // Fail fast
});
```
### Example 3: Enterprise Setup
```php
<?php
// wpfmj-config.php for enterprise with compliance requirements
// Extended retention for audit compliance
add_filter('wpfmj_error_log_retention_days', function($days) {
return 365; // 1 year
});
// Maximum reliability
add_filter('wpfmj_max_retry_attempts', function($attempts) {
return 5;
});
// Security team notifications
add_filter('wpfmj_failure_notification_emails', function($emails) {
return array(
'security@example.com',
'compliance@example.com',
'it-ops@example.com'
);
});
// Use modern encryption
add_filter('wpfmj_encryption_method', function($method) {
return 'AES-256-GCM';
});
```
### Example 4: Minimal Configuration
```php
<?php
// wpfmj-config.php for simple site
// Just increase error retention slightly
add_filter('wpfmj_error_log_retention_days', function($days) {
return 120; // 4 months
});
```
---
## Environment-Specific Configuration
You can use environment variables or constants for different environments:
```php
<?php
// wpfmj-config.php with environment detection
// Detect environment
$is_dev = (defined('WP_DEBUG') && WP_DEBUG === true);
$is_staging = (strpos($_SERVER['HTTP_HOST'], 'staging') !== false);
if ($is_dev) {
// Development settings
add_filter('wpfmj_disable_failure_notifications', '__return_true');
add_filter('wpfmj_debug_mode', '__return_true');
add_filter('wpfmj_max_retry_attempts', function() { return 1; });
} elseif ($is_staging) {
// Staging settings
add_filter('wpfmj_error_log_retention_days', function() { return 30; });
add_filter('wpfmj_failure_notification_emails', function() {
return array('staging-alerts@example.com');
});
} else {
// Production settings
add_filter('wpfmj_error_log_retention_days', function() { return 90; });
add_filter('wpfmj_api_rate_limit', function() { return 120; });
add_filter('wpfmj_failure_notification_emails', function() {
return array(
'ops@example.com',
'monitoring@example.com'
);
});
}
```
---
## Monitoring Your Configuration
### Check Current Settings
Add this to a test plugin or theme's functions.php temporarily:
```php
add_action('admin_init', function() {
if (current_user_can('manage_options') && isset($_GET['wpfmj_check_config'])) {
echo '<pre>';
echo 'Error Retention: ' . apply_filters('wpfmj_error_log_retention_days', 90) . " days\n";
echo 'API Rate Limit: ' . apply_filters('wpfmj_api_rate_limit', 60) . " req/min\n";
echo 'Max Retries: ' . apply_filters('wpfmj_max_retry_attempts', 3) . " attempts\n";
echo 'Debug Mode: ' . (apply_filters('wpfmj_debug_mode', false) ? 'ON' : 'OFF') . "\n";
echo 'Notifications: ' . (apply_filters('wpfmj_disable_failure_notifications', false) ? 'DISABLED' : 'ENABLED') . "\n";
echo '</pre>';
exit;
}
});
```
Visit: `yoursite.com/wp-admin/?wpfmj_check_config`
---
## Troubleshooting Configuration
### Configuration Not Loading
1. **Check file name**: Must be exactly `wpfmj-config.php`
2. **Check file location**: Must be in plugin root directory
3. **Check syntax**: Use PHP linter to verify no errors
4. **Check filters**: Ensure using `add_filter()` not `add_action()`
### Values Not Changing
1. **Clear caches**: Object cache, opcache, page cache
2. **Check filter priority**: Default priority is 10
3. **Verify filter name**: Must match exactly (case-sensitive)
4. **Test with simple value**: Try returning a hardcoded value first
### Debug Logging Not Working
1. **Enable WordPress debug logging**:
```php
// In wp-config.php
define('WP_DEBUG', true);
define('WP_DEBUG_LOG', true);
define('WP_DEBUG_DISPLAY', false);
```
2. **Check debug.log location**: `wp-content/debug.log`
3. **Verify debug mode filter is applied**
---
## Best Practices
### DO:
✅ Use `wpfmj-config.php` for customizations
✅ Keep configuration in version control (except sensitive data)
✅ Document your customizations
✅ Test configuration changes in staging first
✅ Use environment detection for different setups
✅ Monitor logs after configuration changes
### DON'T:
❌ Modify core plugin files directly
❌ Store sensitive data in configuration file
❌ Use extremely high rate limits without testing
❌ Disable notifications without alternative monitoring
❌ Change encryption method after storing credentials
❌ Enable debug mode in production long-term
---
## Performance Considerations
| Setting | Impact | Recommendation |
|---------|--------|----------------|
| Error Retention (Low) | Less DB storage | Good for high-volume |
| Error Retention (High) | More DB storage | Good for compliance |
| API Rate Limit (Low) | Slower processing | More reliable |
| API Rate Limit (High) | Faster processing | Monitor closely |
| Max Retries (Low) | Fast failure | Development |
| Max Retries (High) | Slow failure | Production |
| Cleanup (Frequent) | More CPU usage | High-volume sites |
| Cleanup (Infrequent) | Less CPU usage | Low-volume sites |
---
## Security Considerations
1. **Never commit sensitive data**: Use environment variables for secrets
2. **File permissions**: Set `wpfmj-config.php` to 644 or 600
3. **Encryption changes**: Only change before first use
4. **Debug mode**: Never leave enabled with sensitive operations
5. **Email recipients**: Ensure all recipients are trusted
---
## Getting Help
If you need assistance with configuration:
1. **Check debug logs**: Enable debug mode temporarily
2. **Test with defaults**: Remove config file to use defaults
3. **Verify syntax**: Use PHP linter on config file
4. **Review examples**: See examples in this guide
5. **Contact support**: Include configuration (without sensitive data)

# WPForms to Mailjet Automation Plugin - Complete Summary
## 📋 Overview
This production-ready WordPress plugin creates automated workflows between WPForms submissions and Mailjet contact lists. Users can map form field answers to Mailjet lists through an intuitive React-based wizard interface.
## 🎯 Core Features
### User Interface
- **6-Step Wizard**: Beautiful React interface using @wordpress/components
- **Dashboard**: Manage all automations with status indicators and error counts
- **Actions**: Pause, activate, edit, and delete automations
- **Real-time Validation**: Form validation at each step
### Automation Logic
- **Field Mapping**: Email (required), firstname, lastname (optional)
- **Trigger Fields**: Support for checkbox, radio, dropdown, multi-select
- **Multiple Lists**: Single submission can add contact to multiple lists
- **Smart Mapping**: Each Mailjet list can only be used once per automation
### Reliability
- **Retry Logic**: 3 automatic retry attempts with exponential backoff
- **Error Logging**: Custom database table tracks all failures
- **Admin Notifications**: Email alerts when all retries fail
- **Auto Cleanup**: Old error logs automatically deleted after 90 days
### Security
- **Encrypted Storage**: AES-256-CBC encryption for API credentials
- **Nonce Protection**: All AJAX requests verified
- **Capability Checks**: manage_options required for all operations
- **SQL Safety**: Prepared statements throughout
- **Input Sanitization**: All user input sanitized and validated
### Performance
- **Set and Forget**: No polling or excessive AJAX calls
- **Efficient Queries**: Proper database indexing
- **Minimal Overhead**: Form submission processing is lightweight
- **Optimized Assets**: React bundle minified in production
### Compatibility
- **WooCommerce**: HPOS compatibility declared
- **WPForms**: Works with Lite and Pro versions
- **LearnDash**: No conflicts
- **Wordfence**: No conflicts
- **PHP 7.4+**: Modern PHP features with backward compatibility
- **WordPress 5.8+**: Uses latest WordPress standards

Handles AES-256-CBC encryption/decryption for API credentials. Generates and stores unique encryption key.
### WPFMJ_Mailjet_API
Wrapper around Mailjet REST API. Handles authentication, requests, and error handling.
### WPFMJ_Form_Handler
Processes WPForms submissions. Contains retry logic, error handling, and contact management.
### WPFMJ_Error_Logger
Manages error logging database table. Provides methods for logging, retrieving, and cleaning errors.
### WPFMJ_Admin
Handles all admin AJAX endpoints. Manages form data, API connections, and automation CRUD.
### WPFMJ_Dashboard
Renders admin dashboard page with automation list and management controls.
## 🎨 Wizard Flow
```
Step 1: Choose Form
↓ User selects WPForm and names automation
Step 2: Map Contact Fields
↓ User maps email, firstname, lastname fields
Step 3: Choose Trigger Field
↓ User selects which field determines list assignment
Step 4: Connect Mailjet
↓ User enters and tests API credentials
Step 5: Map Answers to Lists
↓ User maps each answer to a Mailjet list
Step 6: Review & Save
↓ User reviews and saves (draft or active)
Dashboard: Manage Automations
```
## 🔄 Automation Execution Flow
```
1. User submits WPForm
2. wpforms_process_complete hook fires
3. WPFMJ_Form_Handler receives submission
4. Handler finds active automations for form
5. Extract email, firstname, lastname from form data
6. Extract trigger field value(s)
7. Determine which Mailjet lists to add contact to
8. Attempt to add contact via Mailjet API
9. Success? → Done
↓ Failure?
10. Retry (up to 3 times with backoff)
11. All retries failed? → Log error + Email admin
```

#### 1. XSS Vulnerability in AJAX Save Function
**File**: `class-wpfmj-admin.php`
**Function**: `ajax_save_automation()`
**OWASP**: A03:2021 Injection
**Issue**: Form data from `$_POST['data']` was stored without sanitization, allowing potential XSS attacks.
**Fix Applied**:
```php
// Before
$config = array(
'form_id' => intval($data['form_id']),
'field_mapping' => $data['field_mapping'], // ❌ Not sanitized
'list_mappings' => $data['list_mappings'], // ❌ Not sanitized
);
// After
$field_mapping = array(
'email' => sanitize_text_field($data['field_mapping']['email']),
'firstname' => sanitize_text_field($data['field_mapping']['firstname'] ?? ''),
'lastname' => sanitize_text_field($data['field_mapping']['lastname'] ?? ''),
);
$list_mappings = array();
foreach ($data['list_mappings'] as $key => $value) {
$list_mappings[sanitize_text_field($key)] = sanitize_text_field($value);
}
```
**Status**: ✅ Fixed
---
#### 2. Stored XSS in Dashboard
**File**: `class-wpfmj-dashboard.php`
**Function**: `render_dashboard()`
**OWASP**: A03:2021 Injection
**Issue**: Automation titles and form names were output to JavaScript without escaping.
**Fix Applied**:
```javascript
// Before
html += '<td><strong>' + automation.title + '</strong></td>'; // ❌ XSS risk
// After
var title = $('<div>').text(automation.title).html(); // ✅ jQuery escaping
html += '<td><strong>' + title + '</strong></td>';
```
**Status**: ✅ Fixed
---
#### 3. Unescaped Database Output
**File**: `class-wpfmj-error-logger.php`
**Function**: `get_errors()`
**OWASP**: A03:2021 Injection
**Issue**: Error messages returned from database without sanitization.
**Fix Applied**:
```php
// Added sanitization on output
foreach ($results as &$result) {
$result['error_message'] = sanitize_text_field($result['error_message']);
$result['error_type'] = sanitize_text_field($result['error_type']);
}
```
**Status**: ✅ Fixed
---
#### 4. Invalid Form Data Handling
**File**: `class-wpfmj-admin.php`
**Function**: `ajax_get_form_fields()`
**OWASP**: A04:2021 Insecure Design
**Issue**: WPForms decoded data was accessed without structure validation.
**Fix Applied**:
```php
// Added validation
if (!is_array($form_data) || !isset($form_data['fields']) || !is_array($form_data['fields'])) {
wp_send_json_error('Invalid form data structure');
}
// Validate each field before processing
foreach ($form_data['fields'] as $field) {
if (!is_array($field) || !isset($field['type']) || !isset($field['label'])) {
continue; // Skip invalid fields
}
// ... process field
}
```
**Status**: ✅ Fixed
---
### HIGH SEVERITY (All Fixed ✅)
#### 5. Missing API Rate Limiting
**File**: `class-wpfmj-mailjet-api.php`
**Function**: `request()`
**OWASP**: A04:2021 Insecure Design
**Issue**: No rate limiting on Mailjet API requests could lead to abuse or DoS.
**Fix Applied**:
```php
// Added transient-based rate limiting (60 requests per minute)
$rate_limit_key = 'wpfmj_api_rate_' . md5($this->api_key);
$requests = get_transient($rate_limit_key);
if ($requests >= 60) {
return new WP_Error('rate_limit_exceeded', 'API rate limit exceeded...');
}
set_transient($rate_limit_key, $requests + 1, 60);
```
**Status**: ✅ Fixed
---
#### 6. Email Header Injection Risk
**File**: `class-wpfmj-form-handler.php`
**Function**: `notify_admin_of_failure()`
**OWASP**: A03:2021 Injection
**Issue**: Email content not properly sanitized before sending.
**Fix Applied**:
```php
// Added sanitization
$automation_title = sanitize_text_field($automation_title);
$error_message = sanitize_textarea_field($error_message);
$headers = array('Content-Type: text/plain; charset=UTF-8');
wp_mail($admin_email, $subject, $message, $headers);
```
**Status**: ✅ Fixed
---
#### 7. Silent Decryption Failures
**File**: `class-wpfmj-encryption.php`
**Function**: `decrypt()`
**OWASP**: A09:2021 Security Logging
**Issue**: Decryption failures returned empty string, hiding security issues.
**Fix Applied**:
```php
// Before
return ''; // ❌ Hides errors
// After
if ($decrypted === false) {
error_log('WPFMJ Decryption Error: Decryption failed');
return false; // ✅ Proper error signaling
}
```
**Status**: ✅ Fixed
---
#### 8. Unvalidated Decryption Results
**File**: `class-wpfmj-admin.php`
**Function**: `ajax_get_automation()`
**OWASP**: A08:2021 Data Integrity
**Issue**: Decryption failures not checked before use.
**Fix Applied**:
```php
$decrypted_key = WPFMJ_Encryption::decrypt($config['api_key']);
$decrypted_secret = WPFMJ_Encryption::decrypt($config['api_secret']);
if ($decrypted_key === false || $decrypted_secret === false) {
wp_send_json_error('Failed to decrypt API credentials.');
}
```
**Status**: ✅ Fixed
---
### MEDIUM SEVERITY
#### 9. Missing Activation Capability Check
**File**: `class-wpfmj-activator.php`
**Function**: `activate()`
**OWASP**: A01:2021 Broken Access Control
**Issue**: No verification that user can activate plugins.
**Fix Applied**:
```php
public static function activate() {
if (!current_user_can('activate_plugins')) {
return;
}
// ... rest of activation code
}
```
**Status**: ✅ Fixed
---
#### 10. Unsanitized Error Message Storage
**File**: `class-wpfmj-error-logger.php`
**Function**: `log()`
**OWASP**: A03:2021 Injection
**Issue**: Error messages stored without sanitization.
**Fix Applied**:
```php
$wpdb->insert(
$this->table_name,
array(
'automation_id' => intval($automation_id),
'error_type' => sanitize_text_field($error_type),
'error_message' => sanitize_textarea_field($error_message), // ✅ Added
'retry_count' => intval($retry_count),
)
);
```
**Status**: ✅ Fixed
---
#### 11. No Pagination on Dashboard
**File**: `class-wpfmj-admin.php`
**Function**: `ajax_get_dashboard_data()`
**OWASP**: A04:2021 Insecure Design
**Issue**: Could return huge dataset without limits.
**Mitigation**: WordPress `get_posts()` with `posts_per_page => -1` is acceptable for admin interfaces where users typically have limited automations. For production at scale, consider adding pagination.
**Status**: ⚠️ Acceptable (Admin-only, typically low volume)
---
### LOW SEVERITY
#### 12. Missing File Existence Checks
**File**: `class-wpfmj-core.php`
**Function**: `load_dependencies()`
**OWASP**: A05:2021 Security Misconfiguration
**Issue**: `require_once` without `file_exists()` checks.
**Fix Applied**:
```php
// Check for missing files
$missing_files = array();
foreach ($required_files as $file) {
if (!file_exists($file)) {
$missing_files[] = basename($file);
}
}
// If any files are missing, show error and stop loading
if (!empty($missing_files)) {
add_action('admin_notices', function() use ($missing_files) {
// Display error message
});
return;
}
```
**Status**: ✅ Fixed
---
#### 13. Hardcoded Cleanup Period
**File**: `class-wpfmj-error-logger.php`
**Function**: `cleanup_old_logs()`
**OWASP**: A05:2021 Security Misconfiguration
**Issue**: 90-day cleanup period was hardcoded.
**Fix Applied**:
```php
public function cleanup_old_logs($days = null) {
// Allow filtering of retention period
if ($days === null) {
$days = apply_filters('wpfmj_error_log_retention_days', 90);
}
// Ensure positive integer with validation
$days = absint($days);
if ($days < 1) {
$days = 90;
}
// ... cleanup with logging
}
```
**Additional Enhancements**:
- Created `wpfmj-config-sample.php` for user customization
- Added 8 configurable filters for all major settings
- Created comprehensive CONFIGURATION-GUIDE.md
- Added .gitignore to exclude custom config
- Implemented validation for all filter values
- Added error logging for configuration issues

// Add to main plugin file
add_action('admin_init', function() {
if (isset($_GET['page']) && strpos($_GET['page'], 'wpfmj') !== false) {
header("Content-Security-Policy: default-src 'self'; script-src 'self' 'unsafe-inline'; style-src 'self' 'unsafe-inline';");
}
});
```
2. **File Integrity Monitoring**
- Consider adding checksums for critical files

## Detailed Code Changes
### Critical Fix #1: Sanitize AJAX Save Data
**File**: `class-wpfmj-admin.php`
**Before:**
```php
$config = array(
'form_id' => intval($data['form_id']),
'field_mapping' => $data['field_mapping'], // ❌ Direct use
'trigger_field_id' => $data['trigger_field_id'], // ❌ Direct use
'list_mappings' => $data['list_mappings'], // ❌ Direct use
);
```
**After:**
```php
// Validate field_mapping structure
if (!is_array($data['field_mapping']) || !isset($data['field_mapping']['email'])) {
wp_send_json_error('Invalid field mapping structure');
}
$field_mapping = array(
'email' => sanitize_text_field($data['field_mapping']['email']),
'firstname' => isset($data['field_mapping']['firstname']) ? sanitize_text_field($data['field_mapping']['firstname']) : '',
'lastname' => isset($data['field_mapping']['lastname']) ? sanitize_text_field($data['field_mapping']['lastname']) : '',
);
// Validate and sanitize list_mappings
if (!is_array($data['list_mappings'])) {
wp_send_json_error('Invalid list mappings structure');
}
$list_mappings = array();
foreach ($data['list_mappings'] as $key => $value) {
$list_mappings[sanitize_text_field($key)] = sanitize_text_field($value);
}
$config = array(
'form_id' => intval($data['form_id']),
'field_mapping' => $field_mapping,
'trigger_field_id' => sanitize_text_field($data['trigger_field_id']),
'list_mappings' => $list_mappings,
);
```
---
### Critical Fix #2: Escape Dashboard Output
**File**: `class-wpfmj-dashboard.php`
**Before:**
```javascript
html += '<td><strong>' + automation.title + '</strong></td>';
html += '<td>' + automation.form_name + '</td>';
```
**After:**
```javascript
// Escape data for safe HTML output
var title = $('<div>').text(automation.title).html();
var formName = $('<div>').text(automation.form_name).html();
var automationId = parseInt(automation.id);
html += '<td><strong>' + title + '</strong></td>';
html += '<td>' + formName + '</td>';
```
---
### High Priority Fix #3: API Rate Limiting
**File**: `class-wpfmj-mailjet-api.php`
**Before:**
```php
private function request($method, $endpoint, $data = array()) {
$url = $this->api_url . $endpoint;
// ... direct request
}
```
**After:**
```php
private function request($method, $endpoint, $data = array()) {
// Rate limiting: max 60 requests per minute
$rate_limit_key = 'wpfmj_api_rate_' . md5($this->api_key);
$requests = get_transient($rate_limit_key);
if ($requests === false) {
$requests = 0;
}
if ($requests >= 60) {
return new WP_Error('rate_limit_exceeded', 'API rate limit exceeded. Please wait a moment and try again.');
}
set_transient($rate_limit_key, $requests + 1, 60);
$url = $this->api_url . $endpoint;
// ... rest of request
}
```
---
### High Priority Fix #4: Improved Decryption
**File**: `class-wpfmj-encryption.php`
**Before:**
```php
public static function decrypt($data) {
try {
// ... decryption
return openssl_decrypt($encrypted, self::$method, $key, 0, $iv);
} catch (Exception $e) {
error_log('WPFMJ Decryption Error: ' . $e->getMessage());
return ''; // ❌ Silent failure
}
}
```
**After:**
```php
public static function decrypt($data) {
try {
// ... decryption with validation
$decrypted = openssl_decrypt($encrypted, self::$method, $key, 0, $iv);
if ($decrypted === false) {
error_log('WPFMJ Decryption Error: Decryption failed');
return false; // ✅ Explicit failure
}
return $decrypted;
} catch (Exception $e) {
error_log('WPFMJ Decryption Error: ' . $e->getMessage());
return false; // ✅ Explicit failure
}
}
```
