phpcms图片模型调用组图的问题

phpcms里面有个图片模型，之前一直没有用过，之前用的轮播图是用文章+缩略图+推荐位实现的

今天看了一下图片模型添加内容的地方，和平常的文章相比多了一个组图的地方：

也即可以用一篇文章管理多个图片吧

那么我前台需要一个轮播图实现动态展示，怎么调用呢？

本来我是这样调的：因为只有一个文章在返回值$data里，而且键值是id，所以$data[1]，注意需要调用副表，就是那个moreinfo="1"

{pc:content action="lists" catid="11" order="id DESC" moreinfo="1" return="data"}
     {loop $data[1][pictureurls] $r}
           <li class="on">
                <div class="txt_box">
                     <div class="tit"><img src="{$r[url]}" alt="{$r[alt]}" /></div>
                </div>
           </li>
     {/loop}
{/pc}

结果竟然不显示！！！

var_dump了一下$data[1][pictureurls]，没问题啊，可以出来啊！真奇怪

然后查了半天，猛然看到var_dump($data[1][pictureurls])的类型是String。。。

好吧，怪不得呢，记得phpcms全局函数库中有string转array的，查了一下，是string2array方法

然后改成这样调：

{pc:content action="lists" catid="11" order="id DESC" moreinfo="1" return="data"}
      {loop string2array($data[1][pictureurls]) $r}
          <li class="on">
               <div class="txt_box">
                    <div class="tit"><img src="{$r[url]}" alt="{$r[alt]}" /></div>
               </div>
          </li>
      {/loop}
{/pc}

OK了~
