1、打开phpcms\caches\caches_commons\caches_data\category_content_1.cache.php

return array (
  1 => 
  array (
    &#39;catid&#39; => &#39;1&#39;,
    &#39;siteid&#39; => &#39;1&#39;,
    &#39;type&#39; => &#39;1&#39;,
    &#39;modelid&#39; => &#39;0&#39;,
    &#39;parentid&#39; => &#39;0&#39;,
    &#39;arrparentid&#39; => &#39;0&#39;,
    &#39;child&#39; => &#39;1&#39;,
    &#39;arrchildid&#39; => &#39;1,2,3,5,162&#39;,
    &#39;catname&#39; => &#39;网站介绍&#39;,
    &#39;style&#39; => &#39;&#39;,
    &#39;image&#39; => &#39;&#39;,
    &#39;description&#39; => &#39;&#39;,
    &#39;parentdir&#39; => &#39;&#39;,
    &#39;catdir&#39; => &#39;about&#39;,
    &#39;url&#39; => &#39;/html/about/&#39;,
    &#39;items&#39; => &#39;0&#39;,
    &#39;hits&#39; => &#39;0&#39;,
    &#39;setting&#39; => &#39;array (
  \&#39;ishtml\&#39; => \&#39;1\&#39;,
  \&#39;template_list\&#39; => \&#39;default\&#39;,
  \&#39;page_template\&#39; => \&#39;page\&#39;,
  \&#39;meta_title\&#39; => \&#39;\&#39;,
  \&#39;meta_keywords\&#39; => \&#39;\&#39;,
  \&#39;meta_description\&#39; => \&#39;\&#39;,
  \&#39;category_ruleid\&#39; => \&#39;1\&#39;,
  \&#39;show_ruleid\&#39; => \&#39;\&#39;,
  \&#39;repeatchargedays\&#39; => \&#39;1\&#39;,
)&#39;,

category_content_1.cache.php

可以看到，这里缓存了所有栏目类别的详细信息，其中就有我们需要的

'catname' => '网站介绍',

2、打开phpcms\modules\content\classes\content_tag.class.php

/**
     * 列表页标签
     * @param $data
     */
    public function lists($data) {
        $catid = intval($data[&#39;catid&#39;]);
        if(!$this->set_modelid($catid)) return false;
        if(isset($data[&#39;where&#39;])) {
            $sql = $data[&#39;where&#39;];
        } else {
            $thumb = intval($data[&#39;thumb&#39;]) ? " AND thumb != &#39;&#39;" : &#39;&#39;;
            if($this->category[$catid][&#39;child&#39;]) {
                $catids_str = $this->category[$catid][&#39;arrchildid&#39;];
                $pos = strpos($catids_str,&#39;,&#39;)+1;
                $catids_str = substr($catids_str, $pos);
                $sql = "status=99 AND catid IN ($catids_str)".$thumb;
            } else {
                $sql = "status=99 AND catid=&#39;$catid&#39;".$thumb;
            }
        }
        $order = $data[&#39;order&#39;];

        $return = $this->db->select($sql, &#39;*&#39;, $data[&#39;limit&#39;], $order, &#39;&#39;, &#39;id&#39;);

content_tag.class.php

3、在上述代码后加入以下代码

$TYPES = getcache(&#39;category_content_1&#39;,&#39;commons&#39;);//获取类别缓存2         
    foreach ($return as $key=>$v) {                                       
$return[$key][typename]=$TYPES[$v[&#39;catid&#39;]][&#39;catname&#39;];//给lists标签返回的数组中增加一个类别字段
}

4、前台调用方法

{$v[typename]}
