Hi everyone,
we have the following problem in one of our forms. The form consists of three checkbox groups, where the first has a label "offers" and id "offers[]", while the others have no labels and ids "offers1[]" and "offers2[]". In our "On Submit" event, we have a "Handle Arrays" and an "Event Loop", which calls the "on load" event again.
Now, for a text field and a drop down field, this procedure keeps the set values when the event loop is invoked. But the marks in the check box groups disappear. How can we fix this?
Thanks for the help,
best, Skrodde

Hi Skrodde,

What is the Event Loop doing?

If you can put the Event Loop before the Handle Arrays action then the checkbox values will be loaded correctly.

If not then you have to reverse the Handle Arrays action in the On Load event by adding a Custom Code action before the HTML (Render form) action with code like this:

<?php
$offers_array = array(
  'offers',
  'offers1',
  'offers2'
);
foreach ($offers_array as $o ) {
   if ( !empty($form->data[$o]) ) { 
    $form->data[$o] = explode(',', $form->data[$o]);
  }
}
?>

Hi Bob,
thanks for the fast reply. As to your question and suggestion:

What is the Event Loop doing?

The event loop simply calls "load", so I hope, it invokes the "On Load" event.

If you can put the Event Loop before the Handle Arrays action then the checkbox values will be loaded correctly.

This indeed helped, sort of. Now the checkmarks are correctly placed when I submit the form (i.e. reload it). However, they are not processed. Probably, we access them incorrectly. How would I check the state of a checkbox in a checkboxgroup with the "On Load" event? I tried

echo $form->data['offers'];

but it only gives me "Array", independent of the state of the checkboxes in the group "offers". So how I can see whether the checkboxes in "offers" (and in "offers1", "offers2") are checked or not by the user?
