I'm using Drupal 7. I'm trying to add comments to a node but I get this error back:"You are not authorized to post comments". I can't find in the code which variables are being checked to don't allow me to post a comment. Can someone tell me where to look in the code? Thank you very much

Go to: admin/people/permissions

Check de permission:

  • Post comments

Click button "save permission".

You might be looking for the comment_access() function.

Determines whether the current user has access to a particular comment.

There's not much to it:

function comment_access($op, $comment) {
  global $user;

  if ($op == 'edit') {
    return ($user->uid && $user->uid == $comment->uid && $comment->status == COMMENT_PUBLISHED && user_access('edit own comments')) || user_access('administer comments');
  }
}

If you have not already checked, go to People>Permissions>Comments.

  • It is checked, thanks. The thing is that I want to know where in the code the comments system checks the permissions variables: user->id, global['user'], etc...
