Hi,

The data hook documentation (http://wiki.civicrm.org/confluence/display/CRMDOC/CiviCRM+hook+specification) for hook_civicrm_pre implies that the return value can prevent the operation occuring:

* @return mixed             based on op. pre-hooks return a boolean and/or
*                                  an error message which aborts the operation

I am attempting to prevent the deletion of a contact under certain circumstances (dependant upon results from a seperate drupal package) so I looked for where Hook::pre is called in civicrm.

CRM\Contact\BAO\Contact.php line 993 reads:
CRM_Utils_Hook::pre( 'delete', $contactType, $id, CRM_Core_DAO::$_nullArray );

...so contrary to what the docs imply the return value from the hook call is simply discarded, the same applies to all the other calls to CRM_Utils_Hook.

Perhaps I should add this as an issue?

Meanwhile can anyone suggest another approach which will allow me to prevent deletion of a contact?

Thanks,
  Dougall
