Question

我已将Facebook用户的朋友的FBID存储在mysql数据库的字符串中。字符串如下所示：

"fbid1,fbid2,fbid3...etc..."

我正在尝试在视图中使用特定的FBID（例如，调用配置文件图像）。我的问题是，我如何在Laravel 4视图中执行此操作？我正在尝试以下方法：

array = explode(",", {{ Auth::user()->friend_ids_unpacked}});

但是，这只是打印出其他部分为文本的字符串。我知道这是不正确的，但我不知道如何在Laravel的视图中执行php调用。

感谢您的帮助。

Answer 1

你正在尝试做两件不同的事情。假设你想要一群朋友 - 你这样做：

<? $array = explode(",", Auth::user()->friend_ids_unpacked); ?>

然后您可以像这样使用数组：

@foreach ($array as $x)
    <p>This is another id: {{ $x }}</p>
@endforeach

Answer 2

移动花括号以完全包含PHP调用：

{{ $array = explode(",", Auth::user()->friend_ids_unpacked); }}
