function og_user_access_entity in Organic groups 7.2
Same name and namespace in other branches
- 7 og.module \og_user_access_entity()
Check if a user has access to a permission on a certain entity context.
Parameters
$perm: The organic groups permission.
$entity_type: The entity type.
$entity: The entity object, or the entity ID.
$account: (optional) The user object. If empty the current user will be used.
$skip_alter: (optional) If TRUE then user access will not be sent to other modules using drupal_alter(). This can be used by modules implementing hook_og_user_access_alter() that still want to use og_user_access(), but without causing a recursion. Defaults to FALSE.
$ignore_admin: (optional) When TRUE the specific permission is checked, ignoring the "administer group" permission if the user has it. When FALSE, a user with "administer group" will be granted all permissions. Defaults to FALSE.
Return value
Returns TRUE if the user has access to the permission, otherwise FALSE, or if the entity is not in OG context, function will return NULL. This allows a distinction between FALSE - no access, and NULL - no access as no OG context found.
