wordpress模板的各种调用函数

1. wordpress调用最新文章

WordPress最新文章的调用可以使用一行很简单的模板标签wp_get_archvies来实现. 代码如下：

<?php get_archives(‘postbypost’, 10); ?> (显示10篇最新更新文章)

或者

<?php wp_get_archives(‘type=postbypost&limit=20&format=custom’); ?>

后面这个代码显示你博客中最新的20篇文章，其中format=custom这里主要用来自定义这份文章列表的显示样式。具体的参数和使用方法你可 以参考官方的使用说明- wp_get_archvies。(fromat=custom也可以不要，默认以UL列表显示文章标题。)

补充: 通过WP的query_posts()函数也能调用最新文章列表， 虽然代码会比较多一点，但可以更好的控制Loop的显示，比如你可以设置是否显示摘要。具体的使用方法也可以查看官方的说明。

2. wordpress调用随机文章

<?php$rand_posts = get_posts(‘numberposts=10&orderby=rand’);foreach( $rand_posts as $post ) :?><!–下面是你想自定义的Loop–><li><a href=”<?php the_permalink(); ?>”><?php the_title(); ?></a></li><?php endforeach; ?>

复制代码 3. wordpress调用最新留言

下面是我之前在一个Wordpress主题中代到的最新留言代码，具体也记不得是哪个主题了。该代码直接调用数据库显示一份最新留言。其中 LIMIT 10限制留言显示数量。绿色部份则是每条留言的输出样式。

<?phpglobal $wpdb;$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_excerptFROM $wpdb->commentsLEFT OUTER JOIN $wpdb->posts ON ($wpdb->comments.comment_post_ID =$wpdb->posts.ID)WHERE comment_approved = ’1′ AND comment_type = ” ANDpost_password = ”ORDER BY comment_date_gmt DESCLIMIT 10″;$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调用相关文章

在文章页显示相关文章

<?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><?phpendwhile;}}wp_reset_query();?>

5.wordpress调用指定分类的文章

<?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去评论者链接的评论输出

<?phpglobal $wpdb;$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_excerptFROM $wpdb->commentsLEFT OUTER JOIN $wpdb->posts ON ($wpdb->comments.comment_post_ID =$wpdb->posts.ID)WHERE comment_approved = ’1′ AND comment_type = ” ANDpost_password = ”ORDER BY comment_date_gmt DESCLIMIT 10″;$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调用含gravatar头像的评论输出

<?phpglobal $wpdb;$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;?>

上面代码把comment_author的值改成你的ID，18是头像大小，10是评论数量。
