Phpcms V9调用热门TAG要使用Get SQL语句,调用tag数据库,loop循环输出;但V9版本的PHPCMS默认没有完善tag功能,必须下载一个插件;
插件如下:

http://files.cnblogs.com/xltf/phpcms_tag.rar

首先将压缩包解压以后将phpcms文件夹放到根目录覆盖原来的文件夹（其实所有的文件都是新建的）

然后打开phpcms/model/content_model.class.php 找到

if(!$isimport && $data['status']==99) {

在他的上面添加如下代码

// 添加到tags 表开始

if($systeminfo['keywords']){

$this->db_tags = pc_base::load_model('tags_model'); 

//$this->db_tags_content = pc_base::load_model('tags_content_model');

$keywords = strpos($systeminfo['keywords'], ',') !== false ?  explode(',', $systeminfo['keywords']) : explode(' ', $systeminfo['keywords']);

$sql = '';

foreach($keywords as $key){

if($this->db_tags->get_one("`tag`='$key'", 'tagid')){

$this->db_tags->query("UPDATE `phpcms_tags` SET `usetimes`=usetimes+1 WHERE tag='$key'");

}else{

$this->db_tags->query("INSERT INTO `phpcms_tags`(`tag`,`usetimes`,`lastusetime`,`lasthittime`)VALUES('$key',1,".SYS_TIME.",".SYS_TIME.")");

}

$sql .= ",('$key','$urls[0]','$systeminfo[title]',$this->siteid,$modelid,$id,$systeminfo[catid],".SYS_TIME.")\n";

}

if($sql){

$sql = "INSERT INTO `phpcms_tags_content` (`tag`,`url`,`title`,`siteid`,`modelid`,`contentid`,`catid`,`updatetime`) VALUES ".substr($sql, 1);

$this->db_tags->query($sql);

}

}

// 添加到 tags 表结束

找到下面的

$this->content_check_db->update($check_data,array('checkid'=>'c-'.$id.'-'.$this->modelid));

在他的下面添加如下代码

// 添加到tags 表开始

if($systeminfo['keywords']){

$this->db_tags = pc_base::load_model('tags_model'); 

$this->db_tags_content = pc_base::load_model('tags_content_model');

$keywords = strpos($systeminfo['keywords'], ',') !== false ? explode(',', $systeminfo['keywords']) : explode(' ', $systeminfo['keywords']);

$sql = '';

foreach($keywords as $key){

if(!$this->db_tags_content->get_one("`tag`='$key' AND `contentid` = $id AND `catid` =$systeminfo[catid] ", 'contentid')){

if($this->db_tags->get_one("`tag`='$key'", 'tagid')){

$this->db_tags->query("UPDATE `phpcms_tags` SET `usetimes`=usetimes+1 WHERE tag='$key'");

}else{

$this->db_tags->query("INSERT INTO `phpcms_tags`(`tag`,`usetimes`,`lastusetime`,`lasthittime`)VALUES('$key',1,".SYS_TIME.",".SYS_TIME.")");

}

$sql .= ",('$key','$urls[0]','$systeminfo[title]',$this->siteid,$this->modelid,$id,$systeminfo[catid],".SYS_TIME.")\n";

}

}

if($sql){

$sql = "INSERT INTO `phpcms_tags_content` (`tag`,`url`,`title`,`siteid`,`modelid`,`contentid`,`catid`,`updatetime`) VALUES ".substr($sql, 1);

$this->db_tags->query($sql);

}

}

// 添加到 tags 表结束

然后进入后台管理模块;可以看到TAG标签模块;点安装;再重建引索即可

(我这里已经安装,所以显示的是卸载)

最后再使用Get SQL语句就可以把热门标签调用出来了;

{pc:get sql="SELECT tag,hits FROM v9_tags order by hits desc" num="8"} 

<h2>热门标签</h2>

{loop $data $r} 

<a href="{APP_PATH}index.php?m=search&c=index&a=init&typeid=1&q={$r}&time=all">{$r}</a>| 

{/loop}

{/pc}
