How should custom permissions created by hook_civicrm_permission be properly checked?

Have defined custom permission like this:

function mymodulename_civicrm_permission(&$permissions) {
    $prefix = ts('SpecialPermissions') . ': '; // name of extension or module
    $permissions['SpecialPermissions'] = $prefix . ts('SpecialPermissions');
}

and checking it later on, same module, hook_civicrm_buildForm, have tried every option listed below:

* if (CRM_Core_Permission::check('SpecialPermissions')) {
* if (CRM_Core_Permission::check('Drupal: SpecialPermissions')) {
* if (CRM_Core_Permission::check('CiviCRM: SpecialPermissions')) {
* if (CRM_Core_Permission::check('cms: SpecialPermissions')) {

Code looks like exactly according to specs from: * http://wiki.civicrm.org/confluence/display/CRMDOC/hook_civicrm_permission * http://wiki.civicrm.org/confluence/display/CRMDOC/Permission+Reference

However, both test user with a corresponded permission AND Drupal user 1 (UID=1) are being affected, even when Drupal User 1 doesn't have role with custom permissions attached. Not sure if it is by design or something wrong with my implementation of this? Please advice.

I may be misreading this, but it sounds like you're saying that you've got a new permission, and the user with the role that has the permission granted is working just fine. However, you're saying that Drupal user ID 1 is being treated as if it has the permission, even though it doesn't have any role with that permission.

If so, this is totally normal. Drupal user ID 1 gets all permissions, even when using CRM_Core_Permission::check('SpecialPermissions'). You should be able to confirm by creating another user without that permission and seeing that CRM_Core_Permission::check('SpecialPermissions') returns false.

  • Good to know, thanks; a bit unusual behaviour from a drupal user 1 point of view though. – yurg Jan 27 '16 at 19:55
