wordpress模板的各種調用 · wordpress二次開發快速入門

**1. wordpress調用最新文章** WordPress最新文章的調用可以使用一行很簡單的模板標簽wp_get_archvies來實現. 代碼如下： ~~~ <?php get_archives(‘postbypost’, 10); ?> (顯示10篇最新更新文章) ~~~ 或者 ~~~ <?php wp_get_archives(‘type=postbypost&limit=20&format=custom’); ?> ~~~ 后面這個代碼顯示你博客中最新的20篇文章，其中format=custom這里主要用來自定義這份文章列表的顯示樣式。具體的參數和使用方法你可以參考官方的使用說明- `wp_get_archvies。(fromat=custom也可以不要，默認以UL列表顯示文章標題。)` 補充: 通過WP的query_posts()函數也能調用最新文章列表，雖然代碼會比較多一點，但可以更好的控制Loop的顯示，比如你可以設置是否顯示摘要。具體的使用方法也可以查看官方的說明。 **2. wordpress調用隨機文章** ~~~ <?php $rand_posts = get_posts(‘numberposts=10&orderby=rand’); foreach( $rand_posts as $post ) : ?> <!–下面是你想自定義的Loop–> <li><a href=”<?php the_permalink(); ?>”><?php the_title(); ?></a></li> <?php endforeach; ?> ~~~ 復制代碼 **3. wordpress調用最新留言** 下面是我之前在一個Wordpress主題中代到的最新留言代碼，具體也記不得是哪個主題了。該代碼直接調用數據庫顯示一份最新留言。其中 LIMIT 10限制留言顯示數量。綠色部份則是每條留言的輸出樣式。 ~~~ <?php global $wpdb; $sql = “SELECT DISTINCT ID, post_title, post_password, comment_ID, comment_post_ID, comment_author, comment_date_gmt, comment_approved, comment_type,comment_author_url, SUBSTRING(comment_content,1,30) 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 post_password = ” ORDER BY comment_date_gmt DESC LIMIT 10″; $comments = $wpdb->get_results($sql); $output = $pre_HTML; foreach ($comments as $comment) { $output .= “n<li>”.strip_tags($comment->comment_author) .”:” . ” <a href=”” . get_permalink($comment->ID) . “#comment-” . $comment->comment_ID . “” title=”on ” . $comment->post_title . “”>” . strip_tags($comment->com_excerpt) .”</a></li>”; } $output .= $post_HTML; echo $output;?> ~~~ **4.wordpress調用相關文章** 在文章頁顯示相關文章 ~~~ <?php $tags = wp_get_post_tags($post->ID); if ($tags) { $first_tag = $tags[0]->term_id; $args=array( ‘tag__in’ => array($first_tag), ‘post__not_in’ => array($post->ID), ‘showposts’=>10, ‘caller_get_posts’=>1 ); $my_query = new WP_Query($args); if( $my_query->have_posts() ) { while ($my_query->have_posts()) : $my_query->the_post(); ?> <li><a href=”<?php the_permalink() ?>” rel=”bookmark” title=”<?php the_title_attribute(); ?>”><?php the_title();?> <?php comments_number(‘ ‘,’(1)’,’(%)’); ?></a></li> <?php endwhile; } } wp_reset_query(); ?> ~~~ **5.wordpress調用指定分類的文章** ~~~ <?php $posts = get_posts( “category=4&numberposts=10″ ); ?> <?php if( $posts ) : ?> <ul><?php foreach( $posts as $post ) : setup_postdata( $post ); ?> <li> <a href=”<?php the_permalink() ?>” rel=”bookmark” title=”<?php the_title(); ?>”><?php the_title(); ?></a> </li> <?php endforeach; ?> </ul> <?php endif; ?> ~~~ **6.wordpress去評論者鏈接的評論輸出** ~~~ <?php global $wpdb; $sql = “SELECT DISTINCT ID, post_title, post_password, comment_ID, comment_post_ID, comment_author, comment_date_gmt, comment_approved, comment_type,comment_author_url, SUBSTRING(comment_content,1,14) 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 post_password = ” ORDER BY comment_date_gmt DESC LIMIT 10″; $comments = $wpdb->get_results($sql); $output = $pre_HTML; foreach ($comments as $comment) { $output .= “ <li>”.strip_tags($comment->comment_author).”:” . ” <a href=”” . get_permalink($comment->ID) . “#comment-” . $comment->comment_ID . “” title=”on ” . $comment->post_title . “”>” . strip_tags($comment->com_excerpt).”</a></li>”; } $output .= $post_HTML; echo $output;?> ~~~ **7.wordpress調用含gravatar頭像的評論輸出** ~~~ <?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 != ‘鄭永’ 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=”” . $comment->post_title . ” 上的評論”>”. strip_tags($comment->comment_author) .”： “. strip_tags($comment->com_excerpt) .”</a></li>”; } $output .= $post_HTML; $output = convert_smilies($output); echo $output; ?> ~~~ 上面代碼把comment_author的值改成你的ID，18是頭像大小，10是評論數量。 **8.wordpress調用網站統計大全** ***8-1、日志總數：*** <?php $count_posts = wp_count_posts(); echo $published_posts = $count_posts->publish;?> ***8-2、草稿數目：*** <?php $count_posts = wp_count_posts(); echo $draft_posts = $count_posts->draft; ?> ***8-3、評論總數：*** <?php echo $wpdb->get_var(“SELECT COUNT(*) FROM $wpdb->comments”);?> ***8-4、成立時間：*** <?php echo floor((time()-strtotime(“2008-8-18″))/86400);
