php - 如何解析/解码 smarty 模板中的 JSON 对象？

Question

我的模板文件中有以下代码:

{foreach from=$items item=entry}
  <pre>
    {$entry->nb_persons|@print_r}
  </pre>
{/foreach}

输出为(json字符串):

{"ip":"12.12.12.12","date":1375616434,"cartitems":["foo:1"],"company":"dsad","FirstName":"sad","LastName":"asdsad","street":"","postcode":"","city":"","country":"Andorra","phone":"456456","fax":"","email":"sad@sad.com","comefrom":"google","request":"","message":"sadads"}

我想单独打印每个元素，例如:

{$entry->nb_persons.company}

应该给我 -> "dsad"

但这不起作用，我不确定为什么。

JSON 字符串就是字符串。要访问它的成员，你必须从这个字符串创建数组/对象:

{foreach from=$items item=entry}
  {* create array from JSON string*}
  {assign var=person value=$entry->nb_persons|json_decode:1}
  <pre>
    {$person.company}
  </pre>
{/foreach}
