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:content action="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phpcmsmodulescontentclassescontent_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;
[*]}

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;
[*]}

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:content action="hits" catid="0" num="10" order="views DESC" cache="3600"}
调用方法2：
{pc:content action="hits" num="10" order="views DESC" cache="3600"}
