How to use login_display_language_dropdown filter in WordPress

So, you’re diving into the world of WordPress hooks, huh? It’s all about making your WordPress site do exactly what you want without messing with the core code. Let’s chat about the login_display_language_dropdown filter. This hook is your go-to for customizing the Languages select input on the login screen. You’ll want to register it with add_filter in your theme’s functions.php or, better yet, in a custom plugin. That way, when your theme updates, your tweaks remain untouched. Now, let’s get into some examples!

Example 1: Basic Usage

The following example shows how to apply the filter to modify the language dropdown display.

    function weplugins_modify_login_display_language_dropdown_defaults() { 
        // Your custom code here.
        return $allowed_ports; 
    }
    // Add the filter
    add_filter( "login_display_language_dropdown", "weplugins_modify_login_display_language_dropdown_defaults");
    

Example 2: Removing a Hook

If you need to remove a hook callback, here’s how you do it.

    remove_filter( "login_display_language_dropdown", "weplugins_modify_login_display_language_dropdown_defaults");
    

Remember to provide the same callback function name, priority, and number of arguments when removing the hook.

Example 3: Conditional Modifications

You can also make the modifications conditional. Here’s a quick peek at how you might do that.

    function weplugins_conditional_modify_login_display_language_dropdown() { 
        // Your conditional code here.
        return $allowed_ports; 
    }
    // Add the filter
    add_filter( "login_display_language_dropdown", "weplugins_conditional_modify_login_display_language_dropdown");
