PbootCMS生成的 sitemap.xml 中增加 tag 标签链接

// 指定分类标签调用 public function getSortTags($scode) {     $join = array(         array('ay_content_sort b', 'a.scode=b.scode', 'LEFT'),         array('ay_model c', 'b.mcode=c.mcode', 'LEFT')     );     $scode_arr = array();     if ($scode) {         $this->scodes = array(); // 先清空         $scodes = $this->getSubScodes(trim($scode)); // 获取子类         $scode_arr = array(             "a.scode in (" . implode_quot(',', $scodes) . ")",             "a.subscode='$scode'"         );     }     $result = parent::table('ay_content a')         ->where('a.status=1')         ->where("c.type=2 AND a.tags<>'")         ->where($scode_arr, 'OR')         ->join($join)         ->order('a.visits DESC')         ->column('a.tags');     return $result; }

if (!empty($rs = $this->model->getSortTags(''))) {     $tags = implode(',', $rs); // 把栏目tags串起来     $tags = array_unique(explode(',', $tags)); // 再把所有tags组成数组并去重     foreach ($tags as $key2 => $value2) {         if (!in_array($value2, array_column($data, 'tags'))) { // 避免重复输出             $url_rule_type = $this->config('url_rule_type') ?: 3;             if ($url_rule_type == 3) {                 $link2 = Url::home('tag=' . urlencode($value2), '');             } else {                 $link2 = Url::home('tag/' . urlencode($value2));             }             $str .= $this->makeNode($link2, date('Y-m-d'), '0.80');         }     } }
