How to use Event-Switcher

Question

I have a form today CF v4 where I use Event-Switcher [GH]. Is the app for CF v5 similar to that.

I have this code:

<?php
 $user =& JFactory::getUser();
 $user_id = $user->id;
 $pnr = '';
 if ( isset( $form->data['pnr'] ) ) {
   $pnr = $form->data['pnr'];
 }
 if ( !preg_match( "/^\d{8}\-\d{3}\w{1}$/", $pnr ) ) {
   return 'event_b';
$form->errors[''] = 'My error message';
 }
 $db =& JFactory::getDBO();
 $query = "
 SELECT *
   FROM `#__my_table`
   WHERE `pnr` = {$db->quote( $pnr )};
 "; 
 $db->setQuery($query);
 $rows = $db->loadObject();
 $actual_user = $rows->cf_user_id;
 $pnr_exist = $rows->pnr;

 if ( $actual_user == $user_id) {
    return 'event_a';
 }
 elseif ( $pnr_exist ) {
    return 'event_d';
 }

 else {
 return 'event_c';
 }?>

In CFv4 it works but when I try to use the same code in CFv5 nothing happens.

Hi JeLu,

The main difference is that the CFv5 Event Switcher [GH] had a fixed list of four events event_a, event_b, . . . while the CFv5 Event Switcher lets you set your own list of events by putting the list in the Events box at the top, saving the action, re-opening it and clicking the Load Events button.

The ability to create your own events is really helpful in making forms simpler to understand!

If you add the list event_a,event_b,event_c,event_d then it should behave in the same way as the CFV4 version, Note: make a copy of your code just in case it gets lost when the events list is updated.

In your code you should also remove the two & from the =& lines as they are deprecated in more recent version.The $form->errors line may also need to be changed for CFv5.
