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>';
}
}

One change
I had to make one change to this code for it not to give me an error (The second argument for _comment_get_display_setting):
<?php
function phptemplate_comment_wrapper($content, $node) {
$comments_per_page = _comment_get_display_setting('comments_per_page', $node);
$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>'. $content .'</div>';
}
}
?>
Drupal 7?
Please, could anybody post here modification for Drupal 7?
in template.php function
in template.php
function mytemplate_preprocess_comment_wrapper(&$vars) {$vars['top_pager'] = theme('pager');
}
and add in comment-wrapper.tpl.php
<?php if (isset($top_pager)): ?><nav>
<?php print $top_pager; ?>
</nav>
<?php endif; ?>
Great, thanks!
Great, thanks!
