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!
