The seo_booster_ssl_verify filter in SEO Booster allows developers to customize the behavior of SSL verification when the plugin fetches content from a URL. By default, SSL verification is enabled to ensure secure communication, but this filter provides flexibility for specific use cases, such as local development environments with self-signed certificates.
How the Filter Works
When SEO Booster makes an HTTP request to fetch content, it uses the WordPress function wp_remote_get(). By default, SSL verification is enabled to ensure that the connection to the remote server is secure. However, there are scenarios where you might need to disable SSL verification, such as when working in a local development environment with a self-signed SSL certificate.
This is where the seo_booster_ssl_verify filter comes into play. By hooking into this filter, you can programmatically enable or disable SSL verification based on your specific requirements.
Usage Example
To disable SSL verification in a local development environment, you can add the following code to your theme’s functions.php file or a custom plugin:
add_filter('seo_booster_ssl_verify', function($ssl_verify) {
if (defined('WP_LOCAL_DEV') && WP_LOCAL_DEV) {
return false; // Disable SSL verification in local environment
}
return true; // Keep SSL verification enabled in all other environments
});This example checks if the WP_LOCAL_DEV constant is defined and set to true, which indicates a local development environment. If it is, SSL verification is disabled. Otherwise, SSL verification remains enabled.
When to Use This Filter
Use the seo_booster_ssl_verify filter when you need to:
- Disable SSL verification in local or staging environments.
- Handle situations where the remote server has a self-signed or otherwise untrusted SSL certificate.
It is recommended to keep SSL verification enabled in production environments to ensure secure communication.
The seo_booster_ssl_verify filter is a powerful tool for customizing the behavior of SSL verification in SEO Booster. By leveraging this filter, you can ensure that your content fetching processes are secure and flexible, regardless of the environment in which your site is running.
