Our technical choices
PHP file generation
Active snippets are converted into PHP files stored in a dedicated directory (wp-content/wpmastertoolkit/code-snippets
). This offers two advantages:
- Performance Snippets are included via
require_once
to reduce the load on the database. - Security Inactive or invalid snippets are not loaded.
Strict validation
Thanks to the WPMastertoolkit_PHP_Code_Validator
We analyze the code before executing it. This considerably reduces the risk of errors that could break the site.
Compatibility with WordPress best practices
The module is designed to integrate seamlessly into the WordPress ecosystem:
