How to use login_language_dropdown_args filter in WordPress

login_language_dropdown_args filter

Filters default arguments for the Languages select input on the login screen.

To use login_language_dropdown_args 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 WePlugins 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 weplugins_modify_login_language_dropdown_args_defaults which takes 1 parameter and we registered using add_filter. The first parameter login_language_dropdown_args is the name of the hook, the second parameter weplugins_modify_login_language_dropdown_args_defaults is the name of the function which needs to be called, the third parameter is the priority of calling the hook if the same hook is used multiple times, and the last parameter is the number of arguments (if any) to be passed in the registered function.

Sometimes, you have to remove a registered hook so you can use remove_filter to remove login_language_dropdown_args filter.

Parameters

Below the 1 parameter is required to use this hook.

• $args: (array) Arguments for the Languages select input on the login screen.

Live Example

apply_filters( 'login_language_dropdown_args', array $args )

Below is an example of how you can use this hook.

Example 1: Modifying Language Dropdown Arguments

In this example, we modify the default arguments for the language dropdown on the login screen.

    function weplugins_modify_login_language_dropdown_args_defaults($args) { 
        // Update the $args variable according to your website requirements and return this variable.
        // You can modify the $args variable conditionally too if you want.
        return $args; 
    }
    // Add the filter
    add_filter( "login_language_dropdown_args", "weplugins_modify_login_language_dropdown_args_defaults", 10, 1 );
  

Example 2: Removing the Filter

To remove a hook callback, use the example below.

    remove_filter( "login_language_dropdown_args", "weplugins_modify_login_language_dropdown_args_defaults", 10, 1 );
  

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

Example 3: Conditional Modification

In this example, we modify the arguments conditionally based on the user role.

    function weplugins_modify_login_language_dropdown_args_based_on_role($args) { 
        if (current_user_can('administrator')) {
            // Custom modifications for administrators
            $args['something'] = 'value';
        }
        return $args; 
    }
    // Add the filter
    add_filter( "login_language_dropdown_args", "weplugins_modify_login_language_dropdown_args_based_on_role", 10, 1 );
