How to use pre_get_site_by_path filter in WordPress

WordPress development often involves using hooks to modify default behaviors. One such hook is the pre_get_site_by_path filter. This hook allows you to short-circuit the default logic, potentially replacing it with a routine that better fits your setup. To use pre_get_site_by_path, you first need to register it using add_filter. You can add this code to the functions.php file of your active theme or create a custom WordPress plugin. At WePlugins, we recommend creating custom plugins to ensure nothing breaks during theme updates.

Example 1: Modifying Default Site Retrieval

Here’s how you can use pre_get_site_by_path to customize site retrieval logic. We define a function weplugins_modify_pre_get_site_by_path_defaults with five parameters and register it using add_filter.

    function weplugins_modify_pre_get_site_by_path_defaults($site, $domain, $path, $segments, $paths) { 
        // Update the $site variable according to your website requirements and return this variable.
        return $site; 
    }
    // add the filter
    add_filter( "pre_get_site_by_path", "weplugins_modify_pre_get_site_by_path_defaults", 10, 5 );
    

Example 2: Removing a Hook Callback

Sometimes, you might need to remove a registered hook. The example below shows how to use remove_filter to remove the pre_get_site_by_path filter.

    remove_filter( "pre_get_site_by_path", "weplugins_modify_pre_get_site_by_path_defaults", 10, 5 );
    

Ensure you use the same callback function name, priority, and number of arguments when removing the hook callback.

Example 3: Applying Filters

Below is how you can apply the pre_get_site_by_path filter. You can modify the parameters to fit your specific needs.

    apply_filters( 'pre_get_site_by_path', null|false|WP_Site $site, string $domain, string $path, int|null $segments, string[] $paths )
