Dequeue Recaptcha in WordPress - PHP

In this tutorial, we will learn how to dequeue the default Google reCAPTCHA script in WordPress using PHP.

Why should you dequeue reCAPTCHA script?

The default Google reCAPTCHA script that comes with WordPress can create conflicts with other scripts on your website, which can slow down the website's load time and decrease user experience. Dequeuing the script will improve website performance and minimize potential conflicts.

How to dequeue reCAPTCHA script?

The following code will dequeue the default Google reCAPTCHA script in WordPress:

add_action( 'wp_enqueue_scripts', 'remove_default_recaptcha_script', 11 );
function remove_default_recaptcha_script() {
   if( !is_user_logged_in() ) {
      wp_dequeue_script( 'google-recaptcha' );
      wp_deregister_script( 'google-recaptcha' );
   }
}

Code Explanation

1. We use the add_action() function to add remove_default_recaptcha_script() function to the wp_enqueue_scripts hook with a priority of 11. This means our function will run after the default reCAPTCHA script is enqueued and registered.

add_action( 'wp_enqueue_scripts', 'remove_default_recaptcha_script', 11 );

2. In remove_default_recaptcha_script(), we use the is_user_logged_in() function to check if the current user is logged in. This is because reCAPTCHA is mainly used for non-logged-in users to prevent spam and bots.

if( !is_user_logged_in() ) {

3. We dequeue the reCAPTCHA script using the wp_dequeue_script() function.

wp_dequeue_script( 'google-recaptcha' );

4. We deregister the reCAPTCHA script using the wp_deregister_script() function.

wp_deregister_script( 'google-recaptcha' );

Conclusion

In this tutorial, we learned how to dequeue the default Google reCAPTCHA script in WordPress using PHP. By doing so, we can improve website performance and minimize potential conflicts with other scripts.
