The Node Comments module let you assign you own content type as comment. For example, i have the following two content types.

• Food
• Food Comment

Moreover, i also have a view which list out all the food comments for a specific food node id.

• food_comments

So i want to amend the post a comment form under the food_comments view. I did it by hook_views_pre_render().

function <module>_views_pre_render(&$view) {

  if ($view->name == "food_comments") {
    // Load the food node
    $food = node_load(arg(1), NULL, TRUE);

    // Render the post a comment form under list of food comments
    if (function_exists('nodecomment_render') && $food->node_comment) {
      $food->node_comment = NULL;
      $view->attachment_after = nodecomment_render($food, $food->cid);
    }
  }
}

Done =)
