How to use login_form_bottom filter in WordPress

So, you’re diving into the world of WordPress hooks, eh? Let’s talk about the login_form_bottom filter. It’s an interesting one because it kicks in just before the closing form tag. This means you can insert additional content or modify existing elements right before the login form gets wrapped up. To get started with the login_form_bottom filter, you need to register it using add_filter. You can write this code into the functions.php file of your activated theme or, even better, in a custom WordPress Plugin. At WePlugins, we believe in creating custom plugins to ensure nothing breaks when you update your WordPress Theme in the future.

Example 1: Adding Custom Content to the Login Form

In this example, we define a function, weplugins_modify_login_form_bottom_defaults, which takes two parameters. We register it using add_filter. The first parameter is the hook’s name, login_form_bottom, and the second is the function’s name to be called. The third parameter is the priority, and the last one is the number of arguments (if any) to be passed in the registered function.

    function weplugins_modify_login_form_bottom_defaults($content, $args) { 
        // Update the $content variable according to your website requirements.
        return $content; 
    }
    // add the filter
    add_filter( "login_form_bottom", "weplugins_modify_login_form_bottom_defaults", 10, 2 );
    

Example 2: Customizing Content Conditionally

Sometimes, you might want to modify the content conditionally. Here’s how you can do that.

    function weplugins_conditional_login_content($content, $args) {
        if ($args['redirect'] === 'dashboard') {
            $content .= '<p>Welcome back to the dashboard!</p>';
        }
        return $content;
    }
    add_filter("login_form_bottom", "weplugins_conditional_login_content", 10, 2);
    

Example 3: Removing a Hook Callback

To remove a registered hook, use remove_filter. Ensure you provide the same callback function name, priority, and number of arguments while removing the hook callback.

    remove_filter("login_form_bottom", "weplugins_modify_login_form_bottom_defaults", 10, 2);
