Pager at top and bottom of comments

This snippet places a pager at the top of the comments on a node, in addition to the default pager at the bottom.
It is especially useful in forums. For an example theme called 'mytemplate,' add the following to template.php:
<?php
/**
* Add a pager at the top of a list of comments.
*/
function mytemplate_comment_wrapper($content) {
$comments_per_page = _comment_get_display_setting('comments_per_page');
$content = theme('pager', NULL, $comments_per_page, 0) . $content;
return theme_comment_wrapper($content);
}
?>Details
The function comment_render() in comment.module calls theme('comment_wrapper', $output). This theming call will match any hook *_comment_wrapper(), or give up and fall back to theme_comment_wrapper() (which is also in comment.module). This is a great place to jump in and add an extra pager, because the default function only wraps the comments in a <div>.
Line-by-line, the above snippet does the following:
- Retrieve the number of comments per page, which is needed for the pager. This line is copied directly from near the top of
comment_render(). - Prepend a pager to the content (which has already been given a pager at the end). This line is also found in comment.module and allows other theming applied to the pager to function properly.
- Use the default theming function from comment.module to wrap the whole set of pager + comments + pager in a
<div>.

for drupal 6
the same code for drupal 6
function phptemplate_comment_wrapper($content, $node) {
$comments_per_page = _comment_get_display_setting('comments_per_page');
$content = theme('pager', NULL, $comments_per_page, 0) . $content;
if (!$content || $node->type == 'forum') {
return '<div id="comments">'. $content .'</div>';
}
else {
return '<div id="comments"><h2 class="comments">'. t('Comments') .'</h2>'. $content .'</div>';
}
}

Missing something
bboldi, I am trying your snippet (added it on top of themes/garland/template.php) and it seems though that this function is never called.
In order to override it, should it not be (phptemplate_comment_wrapper) defined in includes/theme.inc? Because it is not in my Drupal (6.9). Or am I missing something else?
OK
(Forgot to update... )
Newbie mistake! Wrong location, the snippet works fine. I was just changing the theme on the wrong location (should've been sites/all/themes/whatever_theme). Simply inserting
theme('pager')in new page-forum.tpl.php and page-node.tpl.php works.www.ociozero.com
Thanks everyone for your
