WordPress lostpassword_errors Filter

I spent a couple of hours of searching and another one debugging attempting to find a WordPress filter for errors like the:

ERROR: Invalid username of email.

that appears on the lost password page. Since there’s a registration_errors filter, I thought lostpassword_errors or something close to it would be available. Nope.

/**
 * Used to modify the error messages that are displayed above the login form.
 */
function hook_login_errors( $error ) {
  return $error;
}
add_filter( 'login_errors', 'hook_login_errors' );

Turns out it uses the login_errors filter, cause you know… that makes sense. So, why would you ever need this?

Simple answer. In my particular case, I’m overriding all WordPress registration, login and lost passwords pages. I needed a way to redirect users to my custom lost password page when the lost password form is submitted and errors were found.

Hope this help other WordPress devs out there that have been spending hours searching for the same thing I did. If you have another way, comment below, I’d love to read about it!
