Phpcms V9 调用全站文章排行的解决方案
Phpcms V9 调用全站文章排行的解决方案今天忙于修改网站界面，想在首页添加浏览排行功能，却发现Phpcms竟然不支持调用全站文章排行。下午仔细研究了Phpcms源码，终于找到解决办法。默认情况下，Phpcms只支持调用当前文章排行，代码如下：
{pc:contentaction="hits" catid="$catid" num="10" order="views DESC" cache="3600"}
其中$catid为待调用栏目的id，如果想实现全站调用，需要修改phpcms\modules\content\classes\content_tag.class.php文件，找到以下函数：
/*** 排行榜标签* @param $data*/ public function hits($data) { $catid = intval($data['catid',); if(!$this->set_modelid($catid)) return false; $this->hits_db = pc_base::load_model('hits_model'); $sql = $desc = $ids = ''; $array = $ids_array = array(); $order = $data['order',; $hitsid = 'c-'.$this->modelid.'-%'; $sql = "hitsid LIKE '$hitsid'"; if(isset($data['day',)) { $updatetime = SYS_TIME-intval($data['day',)*86400; $sql .= " AND updatetime>'$updatetime'"; } if($this->category[$catid,['child',) { $catids_str = $this->category[$catid,['arrchildid',; $pos = strpos($catids_str]',')+1; $catids_str = substr($catids_str] $pos); $sql .= " AND catid IN ($catids_str)"; } else { $sql .= " AND catid='$catid'"; } $hits = array(); $result = $this->hits_db->select($sql, '*', $data['limit',, $order); foreach ($result as $r) { $pos = strpos($r['hitsid',,'-',2) + 1; $ids_array[, = $id = substr($r['hitsid',,$pos); $hits[$id, = $r; } $ids = implode(',', $ids_array); if($ids) { $sql = "status=99 AND id IN ($ids)"; } else { $sql = ''; } $this->db->table_name = $this->tablename; $result = $this->db->select($sql, '*', $data['limit',,'','','id'); foreach ($ids_array as $id) { if($result[$id,['title',!='') { $array[$id, = $result[$id,; $array[$id, = array_merge($array[$id,, $hits[$id,); } } return $array; } [/ol,修改代码（见注释）：
/*** 排行榜标签* @param $data*/ public function hits($data) { $catid = intval($data['catid',); $this->hits_db = pc_base::load_model('hits_model'); $sql = $desc = $ids = ''; $array = $ids_array = array(); $order = $data['order',; $hitsid = 'c-'.$this->modelid.'-%'; $sql = "hitsid LIKE '$hitsid'"; if(isset($data['day',)) { $updatetime = SYS_TIME-intval($data['day',)*86400; $sql .= " AND updatetime>'$updatetime'"; } if(!emptyempty($catid) && $catid>0) { //添加判断：id是否为空 if(!$this->set_modelid($catid)) return false; if($this->category[$catid,['child',) { $catids_str = $this->category[$catid,['arrchildid',; $pos = strpos($catids_str]',')+1; $catids_str = substr($catids_str] $pos); $sql .= " AND catid IN ($catids_str)"; } else { $sql .= " AND catid='$catid'"; } } $hits = array(); $result = $this->hits_db->select($sql, '*', $data['limit',, $order); foreach ($result as $r) { $pos = strpos($r['hitsid',,'-',2) + 1; $ids_array[, = $id = substr($r['hitsid',,$pos); $hits[$id, = $r; } $ids = implode(',', $ids_array); if($ids) { $sql = "status=99 AND id IN ($ids)"; } else { $sql = ''; } $this->db->table_name = $this->tablename; $result = $this->db->select($sql, '*', $data['limit',,'','','id'); foreach ($ids_array as $id) { if($result[$id,['title',!='') { $array[$id, = $result[$id,; $array[$id, = array_merge($array[$id,, $hits[$id,); } } return $array; } [/ol,修改代码后，无论设置栏目id为0或空，都能调取全站文章排行。
调用方法1：
{pc:contentaction="hits" catid="0" num="10" order="views DESC" cache="3600"}
调用方法2：
{pc:contentaction="hits" num="10" order="views DESC" cache="3600"}
