Hi
I want to check is somebody already subscribed, the form then should give a message, Sorry, you already subscribed and the form should be "stopped"

I added a new event in the Eventswitcher, called "ingeschreven"
In this event I added a Systemmessage and a Stopper

In the PHP field I put this code

$datum = JRequest::getString('Datum', '', 'post');
$user_info = JRequest::getString('email', '', 'post');
if ( $datum && $user_info ) {
  $db =& JFactory::getDBO();
  $query = "
    SELECT COUNT(*)
      FROM `nestv_chronoengine_chronoforms_data_basic`
      WHERE `Datum` = '{$datum}'
        AND `email` = '{$user_info}';
  ";
  $db->setQuery($query);
  $count = $db->loadResult();
  if ( $count > 0 ) {
  return "ingeschreven";
  }

But the form does not stop, and no systemmessage

Note: I check on "Datum" and "email"
Both fields are in the form en DB table

Where am I going wrong?

Hi Kees,

And where do you have this code ? did you test that it returns the correct value in this case ? please try to "echo" that event name, does it display correctly when the user is subscribed ?

You can also use a "Data read" function, and call your functions in the "found" event, the conditions can be like this:

Model.Datum:{data:Datum}
Model.email:{data:email}

In this case you don't need the code above or the event switcher.

Best regards,
Max

The code is in a PHP section (from "LOGIC")
This code worked fine in V4

Read Data does not work as you proposed

Hi Kees,

Why "Read data" does not work as proposed ?

Can you post a screenshot of your "Events" section at the moment ?

Best regards,
Max
