Using explode within a view in Laravel 4
提问by user1072337
I have stored the FBIDs of a Facebook user's friends in a string in a mysql database. The string looks like this:
我已将 Facebook 用户朋友的 FBID 存储在 mysql 数据库中的字符串中。该字符串如下所示：
"fbid1,fbid2,fbid3...etc..."
I am trying to use specific FBIDs in a view (call profile images, for instance). My question is, how do I do this in a Laravel 4 view? I am trying the following:
我正在尝试在视图中使用特定的 FBID（例如，呼叫个人资料图像）。我的问题是，如何在 Laravel 4 视图中执行此操作？我正在尝试以下操作：
array = explode(",", {{ Auth::user()->friend_ids_unpacked}});
However, this just prints out the string with the other portion as text. I know this is incorrect, but I don't know how to perform a php call within the view in Laravel.
但是，这只是将字符串与其他部分一起打印为文本。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。
Thank you for your help.
感谢您的帮助。

You are trying to do two different things. Assuming that you want to get an array of friends - you do this:
您正在尝试做两件不同的事情。假设你想得到一组朋友 - 你这样做：
<? $array = explode(",", Auth::user()->friend_ids_unpacked); ?>
You can then use the array like this:
然后，您可以像这样使用数组：
@foreach ($array as $x)
<p>This is another id: {{ $x }}</p>
@endforeach

Move your curly braces to fully contain the PHP call:
移动大括号以完全包含 PHP 调用：
{{ $array = explode(",", Auth::user()->friend_ids_unpacked); }}
