html part

      <div id="sc" data-id="{$detail.id}" class="in_right">
        <p id="sc_words">收藏</p>
      </div>

php background processing

  // 商品收藏   1 代表未登入 2代表取消收藏  3 代表 收藏成功 
    public function collect_add(){
      if(empty(session(&#39;uid&#39;))){
        echo &#39;1&#39;;
      }else {
        $collect=M(&#39;collect&#39;);
        $gid=I(&#39;post.gid&#39;);
        //先確定是否已收藏
        $map[&#39;gid&#39;]=$gid;
        $map[&#39;uid&#39;]=session(&#39;uid&#39;);
        $data=$collect->where($map)->find();
        if($data){
          if($data[&#39;status&#39;]==1){
            $collect->where(&#39;id=&#39;.$data[&#39;id&#39;])->setField(&#39;status&#39;,0);
            echo &#39;2&#39;;
          }else{
            $collect->where(&#39;id=&#39;.$data[&#39;id&#39;])->setField(&#39;status&#39;,1);
            echo &#39;3&#39;;
          }
        }else{
          if($collect->create()){
            $collect->gid=$gid;
            $collect->create_time=get_date();

            $collect->status=1;
            $collect->add();
            echo &#39;3&#39;;
          }else{
