Custom error messages for login and lost password forms

When a user enters wrong username/email or password in the login form, I want them to see "Invalid username/email or password." error message. That's easy to do with the following code:

add_filter('login_errors', create_function('$a', "return '<b>Error:</b> Invalid username/email or password.';"));

But with this code, the error message is displayed also in the lost password form. And the part with the wrong password doesn't make sense here, because you enter only username or email.

I found this / but since I don't code, I don't know how to use it or even if it's possible.

Would anyone know how to do this?

• create_function will generate errors on newer versions of PHP, you should switch away from that style of code, though by using create_function you're actually overcomplicating how it works and making things harder – Tom J Nowell ♦ Commented Dec 5, 2022 at 10:12

Try this snippet. You can add custom error messages based on different error codes.

add_filter( 'login_errors', 'custom_login_errros_callback' );

function custom_login_errros_callback( $error ) {
    global $errors;
    $err_codes = $errors->get_error_codes();

    if ( in_array( 'invalid_username', $err_codes ) ) {
        $error = '<b>Error:</b> Invalid username/email or password.';
    }

    if ( in_array( 'incorrect_password', $err_codes ) ) {
        $error = '<b>Error:</b> Invalid username/email or password.';
    }

    if ( in_array( 'empty_username', $err_codes ) ) {
        $error = '<b>Error:</b> Invalid username/email or password.';
    }

    if ( in_array( 'empty_password', $err_codes ) ) {
        $error = '<b>Error:</b> Invalid username/email or password.';
    }

    return $error;
}
