wordpress自带的缓存功能使用介绍(2)-木庄网络博客

代码如下:

<?php
/**
* get recent comments
* @param unknown_type $args
* @return unknown_type
*/
function DeamworkRecentcomments($args='number=5&status=approve'){ $cacheID = md5($args);
//有缓存就直接输出
if($output = wp_cache_get('recentComments_'.$cacheID, 'Winysky')){
echo $output;
return;
} //$rcms = get_comments($args);
global $wpdb; $my_email = "'" . get_bloginfo ('admin_email') . "'";
//自动获取博主邮箱
$rcms = $wpdb->get_results("
SELECT ID, post_title, comment_ID, comment_author, comment_author_email, comment_content
FROM $wpdb->comments LEFT OUTER JOIN $wpdb->posts
ON ($wpdb->comments.comment_post_ID = $wpdb->posts.ID)
WHERE comment_approved = '1'
AND comment_type = ''
AND post_password = ''
AND comment_author_email != $my_email ORDER BY comment_date_gmt
DESC LIMIT 10 "); //print_r($rcms);return;
if(empty($rcms)){
_e('没有数据');
return;
}
//历遍数据
$output = '';
foreach( $rcms as $rcm ){
$author = $rcm->comment_author;
//if($author =='admin'){continue;}
$content = DeamworkStriptags( $rcm->comment_content);
$the_title = get_the_title($rcm->comment_post_ID);
$s_excerpt = convert_smilies( DeamworkSubstr( $content, 200 ) );
$contents = '' . $author . ' on ' . $the_title . '<div class=\'recentcommentslink_excerpt\'>' . get_avatar($rcm->comment_author_email, 64). $s_excerpt . '</div>'; $output .= '<li><div id="C_' . $rcm->comment_ID . '_d" style="display:none">' . $contents . '</div>' . '<a id="C_' . $rcm->comment_ID . '" class="recentcommentslink" >' . get_avatar($rcm->comment_author_email, 32) . '</a></li>'; }
//输出后加入缓存
wp_cache_add('recentComments_'.$cacheID,$output, 'Deamwork');
echo $output;
}

最后，试试效果吧~
