Question

我正在尝试使用各种聪明的foreach属性，如last，first，total但似乎没有任何效果。虽然循环正常工作。以下是我的代码：

{foreach from=$myArray key=icon item=myValues name=myValueArray}  
  {if $myValueArray.first} first element {/if}  
    {$myValues["data"]}  
{/foreach}

我认为它必须简单，所以我使用链接smarty doc和SO问题，但没有确切地讨论这个问题。

来自文档：http://www.smarty.net/docsv2/en/language.function.foreach.tpl

    {foreach} loops also have their own variables that handle properties. 
    These are accessed with: {$smarty.foreach.name.property} with “name” being 
    the name attribute.

    Note
    The name attribute is only required when you want to access a {foreach} property, unlike {section}. Accessing a {foreach} property with name undefined does not throw an error, but leads to unpredictable results instead.


    {foreach} properties are index, iteration, first, last, show, total.

这样：

{foreach from=$myArray key=icon item=myValues name=myValueArray}
// {if $myValueArray.first} first element {/if}
{if $smarty.foreach.myValueArray.first} first element {/if}
{$myValues["data"]}
{/foreach}

使用{if $smarty.foreach.myValueArray.first}。有example 7.12

Smarty foreach属性不起作用
