Php Smarty foreach环路构建阵列

通过一个smarty foreach循环，我通过这样一个数组

{foreach name=aussen item=order_values from=$module_data}
  HEIAS_PARAMS.push(['order_article', '{$module_data.PRODUCTS_ID}']);
{/foreach}

HEIAS_PARAMS.push(['order_article', '1']);
HEIAS_PARAMS.push(['order_article', '2']);
HEIAS_PARAMS.push(['order_article', '3']);

HEIAS_PARAMS.push(['order_article', '1,2,3']);

输出是这样的

{foreach name=aussen item=order_values from=$module_data}
  HEIAS_PARAMS.push(['order_article', '{$module_data.PRODUCTS_ID}']);
{/foreach}

HEIAS_PARAMS.push(['order_article', '1']);
HEIAS_PARAMS.push(['order_article', '2']);
HEIAS_PARAMS.push(['order_article', '3']);

HEIAS_PARAMS.push(['order_article', '1,2,3']);

foreach循环如何获得这样的输出

{foreach name=aussen item=order_values from=$module_data}
  HEIAS_PARAMS.push(['order_article', '{$module_data.PRODUCTS_ID}']);
{/foreach}

HEIAS_PARAMS.push(['order_article', '1']);
HEIAS_PARAMS.push(['order_article', '2']);
HEIAS_PARAMS.push(['order_article', '3']);

HEIAS_PARAMS.push(['order_article', '1,2,3']);

我会按照这些思路来写。

用{if！smarty.foreach.aussen.last}，{/if}写的东西是错误的。foreach.aussen.last的未知标记
