CiviCRM Community Forums (archive)

Is there a way that I can update a contact when they fill out profile fields on the Drupal registration form instead of create a new contact? Our goal is to have a Drupal user created during this process and the contact updated with the additional profile fields.

We are currently send pre-existing contacts a unique URL that would allow us to figure out their ID so we will know if they are an existing contact and can update them.

If I set the eid in hook_formBuild would it then update the contact vs create?

if ($form->getAction() == CRM_Core_Action::ADD) {
   $defaults['eid'] = '12';
   $form->setDefaults($defaults);
}


Thanks for any advice!
