PHPCMS前台文章列表前显示分类名称的25字标题： "轻松实现前台文章分类展示，提升用户体验"

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

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

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['catid']);
        if(!$this->set_modelid($catid)) return false;
        if(isset($data['where'])) {
            $sql = $data['where'];
        } else {
            $thumb = intval($data['thumb']) ? " AND thumb != ''" : '';
            if($this->category[$catid]['child']) {
                $catids_str = $this->category[$catid]['arrchildid'];
                $pos = strpos($catids_str,',')+1;
                $catids_str = substr($catids_str, $pos);
                $sql = "status=99 AND catid IN ($catids_str)".$thumb;
            } else {
                $sql = "status=99 AND catid='$catid'".$thumb;
            }
        }
        $order = $data['order'];

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

content_tag.class.php

3、在上述代码后加入以下代码

$TYPES = getcache('category_content_1','commons');//获取类别缓存2         
    foreach ($return as $key=>$v) {                                       
$return[$key][typename]=$TYPES[$v['catid']]['catname'];//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]}
