Author Topic: problem with filling in default value (Read 497 times)

When I register an event participant, I'd like to set the default value of a custom field to a value from a custom field of the event.

Here's the code I wrote:

Code: [Select]

function mydrupalmodule_civicrm_buildForm($formName, &$form)
{
    if ($formName === 'CRM_Event_Form_Participant')
    {
        // get the id of the event
        $eventID = $form->getVar('_eventId');
        if ($eventID)
        {
            // get the event
            $params = array(
                'version' => 3,
                'sequential' => 1,
                'id' => $eventID,
            );            
            $results = civicrm_api('Event', 'getsingle', $params);            
            if (isset($results['id']) && $results['custom_16'])
            {
                // set the field from the event as default for the registration
                $defaults = array(
                    'custom_20_-1' => $results['custom_16'],                    
                );
                $form->setDefaults($defaults);        
            }
        }
    }
}

Although the setDefaults method gets executed, the field is blank on the screen.

What am I doing wrong?

Thanks in advance for your help.

Do you know if the var on the template is also called 'custom_20_1'? It might well be called custom_20?

Also note that contact reference custom fields need the id tpl field & the name tpl field filled in
