Validate event on creation / modifying and provide error message.

  • I hooked into em_event_save to check whether my taxonomies are valid or not.
    But if I return false, the event is saved anyway and no error appears.
    I also wonder why em_event_validate (or $EM_Event->validate()) isn’t called, which would make more sense.
    What do I miss?

    Code:

    
add_filter('em_event_save','em_event_filter_event_save', 1, 2);
function em_event_filter_event_save($result, $EM_Event)
{
    $condition = true;  // Some condition for invalid taxonomy 

    if ($condition) {
        $EM_Event->add_error('Some error message');
        return false;
    }
    return $result;
}

  • Its not called because you are not calling it.

    Use;
    add_filter(‘em_event_validate_meta’, ‘function_name’, 10, 2)

    Thanks a lot for your fast answer! Worked perfectly:

    
add_filter('em_event_validate_meta','em_taxonomies_event_validate_meta', 1, 2);
function em_taxonomies_event_validate_meta($result, $EM_Event){
    // Do validation stuff
    return count($EM_Event->errors) == 0;
}

    You mean it’s not called by the plugin, just like em_event_save?! I only thought the equivalent of em_event_save is em_event_validate, which is not exactly the case here.
    However it works now as it should! Thanks!

    It is called, but separately. First validate and if that does not fail, save.
    Two different functions.

    It is a custom function (because of the notices that are outputted.

    The WP save only requires proper sanitation, not validation.
