WordPress Development Asked by Zian Tap Chan on October 30, 2021
I’m trying to override the authenticate to edit the default error message.
/**
Purposed: Custom Login Error Message
Description: This function override the default error message on login form.
**/
remove_filter( 'authenticate', 'wp_authenticate_username_password' );
add_filter( 'authenticate', 'custom_authenticate_username_password', 30, 3 );
/**
* Remove WordPress filer and write our own with changed error text.
*/
function custom_authenticate_username_password( $user, $username, $password ) {
if ( is_a($user, 'WP_User') )
return $user;
if ( empty( $username ) || empty( $password ) ) {
if ( is_wp_error( $user ) )
return $user;
$error = new WP_Error();
if ( empty( $username ) )
$error->add('empty_email', __('The username or email field is empty.'));
if ( empty( $password ) )
$error->add('empty_password', __( 'The password field is empty' ));
return $error;
}
$user = get_user_by( 'login', $username );
if ( !$user )
return new WP_Error( 'invalid_username', sprintf( __( 'Invalid username or email address.' ), wp_lostpassword_url() ) );
$user = apply_filters( 'wp_authenticate_user', $user, $password );
if ( is_wp_error( $user ) )
return $user;
if ( ! wp_check_password( $password, $user->user_pass, $user->ID ) )
return new WP_Error( 'incorrect_password', sprintf( __( 'The password you've entered is incorrect.' ),
$username, wp_lostpassword_url() ) );
return $user;
}
Unfortunately, the empty username or password error is not overriding.
The default error message for username and password are;
<strong>Error</strong> : The username field is empty.
<strong>Error</strong> : The password field is empty.
I would like to change it to;
The username or email field is empty.
The password field is empty.
However, the invalid_username
and incorrect_password
are working and I successfully override it.
