How to use load_script_textdomain_relative_path filter in WordPress

load_script_textdomain_relative_path filter

Filters the relative path of scripts used for finding translation files.

To use load_script_textdomain_relative_path filter, first you have to register it using add_filter. You can write this code into functions.php of your activated theme or in a custom WordPress Plugin.

We at Flipper Code, always prefer to create a custom WordPress Plugin while using hooks so nothing breaks when you update your WordPress Theme in the future.

In the below live example, we have defined a function modify_load_script_textdomain_relative_path_defaults which takes 2 parameters and we registered using add_filter. The first parameter load_script_textdomain_relative_path is name of the hook, The second parameter modify_load_script_textdomain_relative_path_defaults is name of the function which need to be called, third parameter is the priority of calling the hook if same hook is used multiple times and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometime, you have to remove a registered hook so you can use remove_filter to remove load_script_textdomain_relative_path filter.

Parameters

Below are the 2 parameters are required to use this hook.

• $relative : (string|false) The relative path of the script. False if it could not be determined.
• $src : (string) The full source URL of the script.

Live Example

apply_filters( 'load_script_textdomain_relative_path', string|false $relative, string $src )

Below is an example how you can use this hook.

                        function modify_load_script_textdomain_relative_path_defaults($relative, $src) { 
   
                            // Update the $relative variable according to your website requirements and return this variable. You can modify the $relative variable conditionally too if you want.

                            return $relative; 
                        }
                        // add the filter
                        add_filter( "load_script_textdomain_relative_path", "modify_load_script_textdomain_relative_path_defaults", 10, 2 );

To remove a hook callback, use the example below.

remove_filter( "load_script_textdomain_relative_path", "modify_load_script_textdomain_relative_path_defaults", 10, 2 );

Please make sure provide the same callback function name, priority and number of arguments while removing the hook callback.
