WordPress一些常用功能调用方法
一、wordpress调用网站统计大全
1、日志总数:
<?php $count_posts = wp_count_posts(); echo $published_posts = $count_posts->publish;?>
2、草稿数目:
<?php $count_posts = wp_count_posts(); echo $draft_posts = $count_posts->draft; ?>
3、评论总数:
<?php echo $wpdb->get_var(“SELECT COUNT(*) FROM $wpdb->comments”);?>
4、成立时间:
<?php echo floor((time()-strtotime(“2008-8-18″))/86400); ?>
5、标签总数:
<?php echo $count_tags = wp_count_terms(‘post_tag’); ?>
6、页面总数:
<?php $count_pages = wp_count_posts(‘page’); echo $page_posts = $count_pages->publish; ?>
7、分类总数:
<?php echo $count_categories = wp_count_terms(‘category’); ?>
8、链接总数:
<?php $link = $wpdb->get_var(“SELECT COUNT(*) FROM $wpdb->links WHERE link_visible = ‘Y’”); echo $link; ?>
9、用户总数:
<?php $users = $wpdb->get_var(“SELECT COUNT(ID) FROM $wpdb->users”); echo $users; ?>
10、最后更新:
<?php $last = $wpdb->get_results(“SELECT MAX(post_modified) AS MAX_m FROM $wpdb->posts WHERE (post_type = ‘post’ OR post_type = ‘page’) AND (post_status = ‘publish’ OR post_status = ‘private’)”);$last = date(‘Y-n-j’, strtotime($last[0]->MAX_m));echo $last; ?>
二、wordpress调用含gravatar头像的评论输出
<?php global $wpdb; $sql = “SELECT DISTINCT ID, post_title, post_password, comment_ID, comment_post_ID, comment_author, comment_date_gmt, comment_approved,comment_author_email, comment_type,comment_author_url, SUBSTRING(comment_content,1,10) AS com_excerpt 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 comment_author != ‘郑 永’ AND post_password = ” ORDER BY comment_date_gmt DESC LIMIT 10″; $comments = $wpdb->get_results($sql); $output = $pre_HTML; foreach ($comments as $comment) { $output .= “ <li>”.get_avatar(get_comment_author_email(‘comment_author_email’), 18). ” <a href=”” . get_permalink($comment->ID) . “#comment-” . $comment->comment_ID . “” title=”” . $comment->post_title . ” 上的评论”>”. strip_tags($comment->comment_author) .”: “. strip_tags($comment->com_excerpt) .”</a></li>”; } $output .= $post_HTML; $output = convert_smilies($output); echo $output; ?>
三、wordpress 非插件调用评论表情
<!–smilies–> <?php function wp_smilies() { global $wpsmiliestrans; if ( !get_option(‘use_smilies’) or (empty($wpsmiliestrans))) return; $smilies = array_unique($wpsmiliestrans); $link=”; foreach ($smilies as $key => $smile) { $file = get_bloginfo(‘wpurl’).’/wp-includes/images/smilies/’.$smile; $value = ” “.$key.” “; $img = “<img src=”{$file}” alt=”{$smile}” />”; $imglink = htmlspecialchars($img); $link .= “<a href=”#commentform” title=”{$smile}” onclick=”document.getElementByIdx_x(‘comment’).value += ‘{$value}’”>{$img}</a> ”; } echo ‘<div class=”wp_smilies”>’.$link.’</div>’; } ?> <?php wp_smilies();?>
