smarty模版使用php标签，如何获取模版变量in: 后端程序
已经assign一个模版变量$assign,由于要做特殊的循环输出，使用for循环，因此使用到了php标签，但是php语句和模版语句的变量作用域是不同的，因此不能直接获取到{{php}}for($i=;$i<count($assign);$i=$i+){
echo '
<ul>
<li> <span class="zz_pic"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i][pic_id])).'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title=""><img src="uploads/thumb_'.$assign[$i][pic].'" alt=""></a></span> <span class="zz_title"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i][pic_id])).'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="">'.$assign[$i][title].'</a></span> </li>
<li> <span class="zz_pic"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i+1][pic_id])).'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title=""><img src="uploads/thumb_'.$assign[$i+1][pic].'" alt=""></a></span> <span class="zz_title"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i+1][pic_id])).'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="">'.$assign[$i+1][title].'</a></span> </li>i></ul>';}
{{/php}}解决的方法是：模版变量全部存在smarty的一个对象里面；只要在for之前进行赋值：$assign = $this->_tpl_vars[assign];{{php}}
$assign = $this->_tpl_vars[assign];
for($i=;$i<count($assign);$i=$i+){
echo '
<ul>
<li> <span class="zz_pic"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i][pic_id])).'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title=""><img src="uploads/thumb_'.$assign[$i][pic].'" alt=""></a></span> <span class="zz_title"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i][pic_id])).'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="">'.$assign[$i][title].'</a></span> </li>
<li> <span class="zz_pic"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i+1][pic_id])).'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title=""><img src="uploads/thumb_'.$assign[$i+1][pic].'" alt=""></a></span> <span class="zz_title"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i+1][pic_id])).'" rel="external nofollow" rel="external nofollow" rel="external nofollow" rel="external nofollow" title="">'.$assign[$i+1][title].'</a></span> </li>i></ul>';}
{{/php}}
