comment_reply(
$nid, $pid = NULL)- 6
comment_reply($node, $pid = NULL)
This function is responsible for generating a comment reply form. There are several cases that have to be handled, including:
- replies to comments
- replies to nodes
- attempts to reply to nodes that can no longer accept comments
- respecting access permissions (
'access comments'
,'post comments'
, etc.)
