给WordPress添加快速导航功能

给您的主题添加如小站所示的快速导航功能，如下图所示：

ksdh

步骤如下：

1、在header.php中<head></head>之间加入如下代码：

<script type="text/javascript" src="<?php bloginfo('template_directory'); ?>/js/facebox.js"></script>
<script type="text/javascript">
  jQuery(document).ready(function($) {
    $('a[rel*=facebox]').facebox()
  })
</script>

2、在header.php（或者其他文件）适当的位置加上：
<span><a href="#mydiv" rel="facebox">快速导航</a></span>
在header.php（或者其他文件）适当的位置加上：

<div id="mydiv" style="display:none">
  <div>
   <h2>按月归档</h2>
   <ul>
    <?php wp_get_archives('type=monthly&limit=12'); ?>
   </ul>
  </div>
  <div>
   <h2>网站分类</h2>
   <ul>
    <?php wp_list_cats('show_count=1'); ?>
   </ul>
  </div>
  <div>
   <h2>随机阅读</h2>
   <ul>
    <?php random_posts ($limit=11, $length=400) ; ?>
   </ul>
  </div>
</div>

3.将random_posts函数的相关定义放入functions.php中：

function random_posts ($limit = 5, $length = 400, $before = '<li>', $after = '</li>', $show_pass_post = false, $show_excerpt_in_title = true) {
    global $wpdb, $tableposts;
    $sql = "SELECT ID, post_title, post_date, post_content FROM $tableposts WHERE post_status = 'publish' ";
if(!$show_pass_post) $sql .= "AND post_password ='' ";
$sql .= "ORDER BY RAND() LIMIT $limit";
    $posts = $wpdb->get_results($sql);
$output = '';
    foreach ($posts as $post) {
       $post_title = stripslashes($post->post_title);
$post_date = mysql2date('j.m.Y', $post->post_date);
       $permalink = get_permalink($post->ID);
$post_content = strip_tags($post->post_content);
$post_content = stripslashes($post_content);
$post_strip = substr($post_content,0,$length);
       $post_strip = utf8_trim($post_strip);
$post_strip = str_replace('"', '', $post_strip);
$output .= $before . '<a href="' . $permalink . '" rel="bookmark" title="';
if($show_excerpt_in_title) {
  $output .= $post_strip . '... ';
          } else {
  $output .= 'Permanent Link: ' . str_replace('"', '', $post_title) . '...   ';
}
$output .= $post_date . '">' . $post_title . '</a>';
if(!$show_excerpt_in_title) {
  $output .= ': ' . $post_strip . '... ';
          }
$output .= $after;
}
echo $output;
}
