I suggest you to use the RecentComments Plugin. It comes with gravatar and widget support and tons of other features.
Two steps to modify that code:
1. Add comment_author_email to the list of things it’s getting in the SELECT statement.
2. echo get_avatar( $comment->comment_author_email, 32 ); where you want the gravatar in the comments loop.
A while back I edited a version needing updated badly. I don’t remember were I got it but this plugin seems to work fine in 2.8
The Plugin:
<?php
/*
Plugin Name: Recent Comments with Gravatar:
Version: 0.2
Description: Recent Comments with Gravatar. Editied for WordPress 2.8.0
Author: Unknown
*/
function recent_comments($g_size = 30, $no_comments = 10, $comment_lenth = 60, $show_pass_post = false) {
global $wpdb, $tablecomments, $tableposts;
$request = "SELECT ID, comment_ID, comment_content, comment_author, comment_author_email FROM $tableposts, $tablecomments WHERE $tableposts.ID=$tablecomments.comment_post_ID AND post_status = 'publish' ";
if(!$show_pass_post) { $request .= "AND post_password ='' "; }
$request .= "AND comment_approved = '1' ORDER BY $tablecomments.comment_date DESC LIMIT $no_comments";
$comments = $wpdb->get_results($request);
foreach ($comments as $comment) {
$comment_id = $comment->comment_ID;
$comment_content = strip_tags($comment->comment_content);
$comment_excerpt = mb_substr($comment_content, 0, $comment_lenth)." [...]";
$permalink = get_permalink($comment->ID)."#comment-".$comment->comment_ID;
$comment_author_email = $comment->comment_author_email;
echo '<div class="gravitar">';
echo "<p class=\"li".$comment_id."\">";
if (function_exists('get_avatar')) {
if ('' == $comment->comment_type) {
echo get_avatar($comment->comment_author_email, 40);
} elseif ( ('trackback' == $comment->comment_type) || ('pingback' == $comment->comment_type) ) {
echo get_avatar($comment->comment_author_url, 40);
}
} elseif (function_exists('gravatar')) {
echo "<img src=\"";
if ('' == $comment->comment_type) {
echo gravatar($comment->comment_author_email);
} elseif ( ('trackback' == $comment->comment_type) || ('pingback' == $comment->comment_type) ) {
echo gravatar($comment->comment_author_url);
}
echo "\" alt=\"\" class=\"avatar\" />";
}
echo "</p>\n";
echo '</div>' ;
echo '<div class="comments_exrpt">';
echo " <a href=\"" . $permalink . "\" title=\"View the entire comment\">";
echo $comment_excerpt;
echo "</a>";
echo '</div>' ;
}
}
?>
Add this to your theme:
<?php
if(function_exists('recent_comments')) {
recent_comments(30, 10, 100, false);
}
?>
css:
.comments_exrpt{margin-bottom:15px;width:260px;}
.comments_exrpt a{color:#ffc;font-family:Verdana;font-size:65.5%;}
great plugin, mobster, workd great but im trying to push it further
im trying to order or group the comments by posts, and displaying the post title above the comments
something like this
Post title
Gravatar – Author @ date, time
Comment excerpt
—
Gravatar – Author @ date, time
Comment excerpt
*****
Post Title 2
Gravatar – Author @ date, time
Comment excerpt
—
Gravatar – Author @ date, time
Comment excerpt
all i have done is to retrieve the post author and date, but the post title doesn’t work, it echoes the current post title
any help will be very appreciated
I actually have a function that you can just call from your recent comments loop.
function gravatar($rating = false, $size = false, $default = false, $border = false) {
global $comment;
$out = "http://www.gravatar.com/avatar/".md5($comment->comment_author_email)."png";
if($rating && $rating != '')
$out .= "?r=".$rating;
if($size && $size != '')
$out .="&s=".$size;
if($default && $default != '')
$out .= "&d=".urlencode($default);
if($border && $border != '')
$out .= "&border=".$border;
echo $out;
}
