Custom Errors Filter not working

Replies: 0

I have a problem with a filter: I created a mu-plugin with this code to validate a field hidden by css that must remain empty (as an antibot field):

add_filter( 'forminator_custom_form_submit_errors', 'check_form_data', 99, 3 );

function check_form_data( $submit_errors, $form_id, $field_data_array ) {

    $valid = false;

    $antibotFieldName = "";

    foreach( $field_data_array as $val ) {

        if( $val['placeholder'] == 'antibot' ) {

            $antibotVal = $val['value'];

            $antibotFieldName = $val['name'];

            if($antibotVal == ""){

                $valid = true;

            }

            break;

        }

    }

    if( ! $valid ) {

        $submit_errors[][$antibotFieldName] = 'Antibot verifica fallita!';

    }

    return $submit_errors;

}

but I can’t make it work, it’s ignored..am I missing something?

Thanks
