I'm using hook_comment_view($comment) and I'd like to confer the uid from the comment ($comment->uid) with the uid from the node on which is commented. I thought of $node->uid, but I don't know how I can define $node.

Any suggestions?

  • Did you dpm() the $comment to see if the node is there? I can't remember.

  • @MPD: Thanks to your dpm() hint, I found out that I could load the nid via $comment.

I could load the $nid via the comment and confer the uid's like this:

function mymodule_comment_view($comment) {
 $nid = $comment->nid;
 $node = node_load($nid);
 if ($comment->uid == $node->uid){
    //do something

    You can likely simplify this, too, by getting the $node->uid via a query. Something like $uid = db_query('SELECT n.uid FROM {node} n INNER JOIN {comment} c ON c.nid = n.nid WHERE c.cid = :cid', array(':cid' => $comment->cid))->fetchField(); would be a start.

  • Full node loads can be expensive, especially if you have a lot of fields. It is worth spending a little time with it, even if it is just to get used to doing db_queries for simple things.

  • @MPD: Indeed, running the code seems to go faster now. Thanks for your advice!
