How to use login_title filter in WordPress

So, you’re diving into the world of WordPress hooks, huh? They’re pretty nifty, letting you tweak and extend WordPress without hacking the core files. Today, we’re going to chat about the login_title filter. This one lets you change the title tag on the login page. Trust me, it’s as cool as it sounds!

To get started with the login_title filter, you gotta register it using add_filter. You can pop this into your theme’s functions.php or, even better, create your own custom WordPress plugin. At WePlugins, we always recommend the plugin route. That way, your changes don’t get wiped out when you update your theme.

Example 1: Changing the Login Page Title

Let’s see a simple example of how to use the login_title filter. We’ve got a function called modify_login_title_defaults that takes two parameters. Here’s how you register it:

    function weplugins_modify_login_title_defaults($login_title, $title) { 
        // Update the $login_title variable according to your website requirements and return this variable.
        return $login_title; 
    }
    // add the filter
    add_filter("login_title", "weplugins_modify_login_title_defaults", 10, 2);
    

Example 2: Removing the Filter

Sometimes, you might want to remove a hook. No worries, you can do that with remove_filter. Just make sure you match the callback function name, priority, and number of arguments:

    remove_filter("login_title", "weplugins_modify_login_title_defaults", 10, 2);
    

Example 3: Customizing the Title Further

Here’s a more advanced example. This time, we modify the login title to include our site name:

    function weplugins_customize_login_title($login_title, $title) {
        $login_title = $title . ' ‹ ' . get_bloginfo('name') . ' — Powered by WordPress';
        return $login_title;
    }
    add_filter("login_title", "weplugins_customize_login_title", 10, 2);
