So, you’re diving into WordPress hooks, eh? Let me tell you about the export_wp_filename filter. This hook is used to filter the export filename. You might be wondering how to use it. Well, you’ll need to register it using add_filter. You can place this code in the functions.php of your activated theme or, even better, in a custom WordPress plugin. This way, your changes remain intact even when you update your theme. WePlugins always recommends creating a custom plugin for such modifications.
Example 1: Basic Usage of export_wp_filename
Here’s a simple way to use the export_wp_filename filter. In this example, we define a function modify_export_wp_filename_defaults and register it with the hook.
function weplugins_modify_export_wp_filename_defaults($wp_filename, $sitename, $date) {
// Update the $wp_filename variable according to your website requirements and return this variable.
return $wp_filename;
}
// add the filter
add_filter( "export_wp_filename", "weplugins_modify_export_wp_filename_defaults", 10, 3 );
Example 2: Conditional Filename Modification
Sometimes, you might want to change the filename based on certain conditions. Here’s how you can achieve that.
function weplugins_conditional_export_wp_filename($wp_filename, $sitename, $date) {
if ($sitename === 'MySpecialSite') {
$wp_filename = 'special_' . $wp_filename;
}
return $wp_filename;
}
add_filter( "export_wp_filename", "weplugins_conditional_export_wp_filename", 10, 3 );
Example 3: Removing the Hook
There might be scenarios where you need to remove a previously registered hook. Here’s how you can do it.
remove_filter( "export_wp_filename", "weplugins_modify_export_wp_filename_defaults", 10, 3 );
Ensure you provide the same callback function name, priority, and number of arguments while removing the hook callback.
