How do I print a single comment in drupal?


I want to print a individual comment in drupal based on it's comment ID. How can I do this? Google and other sources have yielded me nothing. Thank you.


Solution

  • Eaton's suggestion is good (except it's {comments}, not {comment}) if you need to display the comment like core does it, including the info coming from the node. Except the default theme_comment implementation in modules/comment/comment.tpl.php makes no use of $node.

    However, I'd do it slightly differently, because if you need to extract a single comment, displaying it with the normal content formatting provided by comment.tpl.php is likely to be inappropriate.

    function print_comment($cid) {
      $sql = "SELECT * FROM {comment} c WHERE c.cid = %d";
      if ($comment = db_fetch_object(db_rewrite_sql(db_query($sql, $cid), 'c'))) {
        return theme('my_special_comment_formatting', $comment);
      }
    }
    

    And of course, define this special commment formatting in your module's hook_theme() implementation, inspired by what comment.tpl.php does.

    2014-02 UPDATE: note that this is a 2009 question/answer. In Drupal 8, you just don't want to access the hypothetical underlying SQL database (and would not do it like this anyway, but use DBTNG), but just use something like:

    if ($comment = entity_load('comment', $cid)) {
      return entity_view($comment, $view_mode);
    }
