remove published post notice while error handled

4 Views

im creating an error handler for a custom post type. 

add_filter( 'wp_insert_post_data' , 'filter_post_data' , '99', 2 );
function filter_post_data( $data , $postarr )
{
    //error handling
    if($data['post_type'] == 'post_annunci')
    {
        if($postarr['annuncio_prezzo'] == '' || !is_numeric($postarr['annuncio_prezzo']))
        {
            $errors .= 'Annuncio non salvato, devi inserire un prezzo con valori numerici.</br>prezzo = '.$postarr['annuncio_prezzo'];
            update_option('my_admin_errors', $errors);

            $data['post_status'] = 'draft';
        }
    }
    return $data;

}

add_action( 'admin_notices', 'admin_error_handler_annunci' );
function admin_error_handler_annunci() {

    $errors = get_option('my_admin_errors');

    if($errors) 
        echo '<div class="error"><p>' . $errors . '</p></div>';
}
// Clear any errors
add_action( 'admin_footer', 'clear_error_handler_annunci' );
function clear_error_handler_annunci() {

    update_option('my_admin_errors', false);
}

This works perfectly but i get a “published post” notice that i want to remove.

Is there some way to get rid of that message?
I seen some sort of notice remover like this script, but works only for update notices. 

function hideUpdateNag() {
    remove_action( 'admin_notices', 'update_nag', 3 );
}
add_action('admin_menu','hideUpdateNag');

  1. Yes. It is possible with the filter post_updated_messages. 

    add_filter( 'post_updated_messages', 'remove_all_messages_so_16015959' );

function remove_all_messages_so_16015959( $messages )
{
    return array();
}

    In this example, an empty array is returned. Resulting in no messages at all.
    This can be fine tuned using the sample values bellow, which are the contents of $messages before the filter.

    Array
(
    [post] => Array
        (
            [0] =>

        )
