1.代码位置 upload/model/ajax.class.php function Atn_action()

function Atn_action()
	{
		$id=(int)$_POST['id'];
		if((int)$_POST['id']>0){
			if($this->uid>0){
				if($_POST['id']==$this->uid){
					echo 4;die;
				}
				$atninfo = $this->obj->DB_select_once("atn","`uid`='".$this->uid."' AND `sc_uid`='".$id."'");//查询是不是关注过了
				$user=$this->obj->DB_select_once("member","`uid`='".$id."'","`usertype`");//查询想关注别人的你的信息
				if($user['usertype']=="1")//确定求职者身份
				{
					$table="resume";
				}elseif($user['usertype']=="2"){//招聘者身份
					$table="company";
				}
				$comurl = $this->furl(array("url"=>"c:profile,id:".$id));
				$row=$this->obj->DB_select_once("friend_info","`uid`='".$id."'");
				$name = $row['nickname'];
				if(is_array($atninfo)&&!empty($atninfo))//判断关注过就会取消关注
				{
					：：
				}else{//否则关注
					：：
				}
			}else{
				echo "3";die;
			}

只需id,uid为大于0的值
2.代码位置 upload/ask/model/index.class.php
function attention_action()
{
$this->is_login();//判断登录
$is_set=$this->obj->DB_select_once("attention","`uid`='".$this->uid."' and `type`='".(int)$_POST['type']."'");
if($_POST['type']=='1')
{
$info=$this->obj->DB_select_once("question","`id`='".(int)$_POST['id']."'","`id`,`title`,`uid`");
$gourl= $this->aurl(array("url"=>"c:content,id:".$info['id']));
$content="关注了<a href=\"".$gourl."\" target=\"_blank\">《".$info['title']."》</a>。";//关注别人
$n_contemt="取消了对<a href=\"".$gourl."\" target=\"_blank\">《".$info['title']."》</a>的关注。";//取消关注别人
}else{
$info=$this->obj->DB_select_once("q_class","`id`='".$_POST['id']."'","`id`,`name`");
$gourl= $this->aurl(array("url"=>"c:getclass,id:".$info['id']));
$content="关注了<a href=\"".$gourl."\" target=\"_blank\">".$info['name']."</a>。";//关注互联网
$n_contemt="取消了<a href=\"".$gourl."\" target=\"_blank\">".$info['name']."</a>的关注。";//取消关注互联网
}
看登录这里
function is_login()
{
if($this->uid==""||$_COOKIE['username']=='')
{
echo 'no_login';die;
}
}
只判断是否为空
只需有type=1或2，id、uid、username有值
