怎么在smarty里面的循环中进行assign
这个是smarty里面的代码

PHP code

$i=0;
$db->Query("brand_list","select * from `category` where `pid`='2' order by id");//总共有4个结果
while($array = $db->GetArray("brand_list")){
    $brand_list[] = $array;
    $i++;
    $wf->assign("i",$i);
    //echo $i.',';
}
$wf->assign('brand_list',$brand_list);

Copy after login


这个是模板里面的代码
HTML code

{foreach from=$brand_list item=list}
    {$i},
{/foreach} 

Copy after login


现在就是在php里面echo 一下的话输出的就是正确的结果:1,2,3,4,
但是在模板里面就是输出的4,4,4,4,

我知道可以在模板里面实现自加,这边只是举了个例子。
我想问的是怎么在php的循环里面去进行assign,从而能够使模板能够正常的输出我想要的东西。

不知道表达的够不够清楚。

------解决方案--------------------
$i=0;
$db->Query("brand_list","select * from `category` where `pid`='2' order by id");//总共有4个结果
$index = array();
while($array = $db->GetArray("brand_list")){
$brand_list[] = $array;
$i++;
$index[] = $i;
//echo $i.',';
}
$wf->assign("i",$index);
$wf->assign('brand_list',$brand_list);


{foreach from=$brand_list item=list key=key}
{$i[$key]},
{/foreach}
