comment_access($op, $comment)
comment/comment.module, line 573
Description
This is *not* a hook_access() implementation. This function is called to determine whether the current user has access to a particular comment.
Authenticated users can edit their comments as long they have not been replied to. This prevents people from changing or revising their statements based on the replies to their posts.
Code
<?php
function comment_access($op, $comment) {
global $user;
if ($op == 'edit') {
return ($user->uid && $user->uid == $comment->uid && comment_num_replies($comment->cid) == 0) || user_access('administer comments');
}
}
?>
