已經assign一個模版變量$assign,由于要做特殊的循環(huán)輸出，使用for循環(huán)，因此使用到了php標簽，但是php語句和模版語句的變量作用域是不同的，因此不能直接獲取到

{{php}}

for($i=0;$i<count($assign);$i=$i+2){
echo '
<ul>
<li> <span class="zz_pic"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i][pic_id])).'" title=""><img src="uploads/thumb_'.$assign[$i][pic].'" alt=""></a></span> <span class="zz_title"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i][pic_id])).'" title="">'.$assign[$i][title].'</a></span> </li>
<li> <span class="zz_pic"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i+1][pic_id])).'" title=""><img src="uploads/thumb_'.$assign[$i+1][pic].'" alt=""></a></span> <span class="zz_title"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i+1][pic_id])).'" title="">'.$assign[$i+1][title].'</a></span> </li>i>

</ul>';}
{{/php}}

解決的方法是：模版變量全部存在smarty的一個對象里面；只要在for之前進行賦值：$assign = $this->_tpl_vars[assign];

{{php}}
$assign = $this->_tpl_vars[assign];
for($i=0;$i<count($assign);$i=$i+2){
echo '
<ul>
<li> <span class="zz_pic"><a href="'._url('picture',array('col_key'=>'cert','pic_id'=>$assign[$i][pic_id])).'" 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])).'" 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])).'" 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])).'" title="">'.$assign[$i+1][title].'</a></span> </li>i>

</ul>';}
