怎么在smarty里面的循环中进行assign
这个是smarty里面的代码
- PHP code
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> $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);
这个是模板里面的代码
- HTML code
<!-- Code highlighting produced by Actipro CodeHighlighter (freeware) http://www.CodeHighlighter.com/ --> {foreach from=$brand_list item=list} {$i}, {/foreach}
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。

$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}

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
