function hook_node_registration_access in Node registration 7

Implements hook_node_registration_access().

Override standard NR access for any operation.

Parameters

NodeRegistrationEntityClass $registration: The relevant $registration, which might be new (so no registration_id) in case of operation 'add'/'create'.

string $op: The operation this access overrides. One of: delete, view, cancel, edit/update, add/create. The last two have aliases you must check for.

stdClass $account: The relevant user object that tries to do this $op to this $registration. Never empty;

string $reason: The reason the standard NR access was FALSE. Relevant for all operations. If the reason is unknown, this will be '?', so it's only empty IF access was granted by standard NR logic. This argument is useful if your code has expensive logic to disallow a certain operation: if $reason is not empty AND you're the only module overriding this access, your expensive code doesn't have to run.
