李文凯老师请速度进一下，急急急

$groupbuy_id = intval ( $_GET ['id'] );
        $proDetail = D ( 'GroupbuyView' )->getGroupbuy ( array ('groupbuy_id' => $groupbuy_id ) );
        $proDetail['pro'] = D('App.Gift')->where("id = {$proDetail['products_id']}")->find();
        
        //产品图片
        $id = 947;
        $pic = D ( 'PubAttachFile' )->loadImg ( $id );
        dump($pic);
        $img = $this->getImg ( json_encode ( $pic ), 4 );
        $this->assign ( 'img', $img );

老师，请帮我估计下代码是怎么回事吧，我把下面查询产品图片的查询放到最上面，就能查到值，可放到下面来就查不到了，请问下是怎么回事

我的D(''PubAttachFile'')这个MODEL是继承另一个配置MODEL，里面写的是另一个数据库连接

你看下这里是不是有终止的代码
    $proDetail = D ( 'GroupbuyView' )->getGroupbuy ( array ('groupbuy_id' => $groupbuy_id ) );
        $proDetail['pro'] = D('App.Gift')->where("id = {$proDetail['products_id']}")->find();

说下我不是李文凯老师，呵呵~~~~
