Smarty：如何使用Php代码获取foreach变量

Question

My Code:

 <!--    {foreach from=$goods_cat.cat_id item=rec_cat name=f1}-->

       <?php      
         **echo  $rec_cat[id]; // get nothing, why?**
        $smarty->assign('goods_cat_' . $rec_cat[id], assign_cat_goods($rec_cat[id], 4));
        $smarty ->assign('cat_goods_nf' , 'goods_cat_' . $rec_cat[id]);           
?>
     <!--{foreach from=$cat_goods_nf item=goods}-->
                  {$goods.url}
     <!--{/foreach}--> 

  <!--{/foreach}--> 

I need the id of rec_cat ,so I use PHP Tags to get it,but Its display nothing? why ?How can I correct it?

Don't use <?php tag inside a template, but instead use {php} tag of Smarty :

Then you get your variables just like so :

$var = $this->get_template_vars('var');
