How to get the values for a series of checkboxes in Laravel 4 controller (if checked)
提问by user1072337
I would like to get the values for a series of checkboxes I have set up in a Laravel 4 form. Here is the code in the view setting up the checkboxes:
我想获取我在 Laravel 4 表单中设置的一系列复选框的值。这是视图中设置复选框的代码:
@foreach ($friends as $friend)
<input tabindex="1" type="checkbox" name="friend[]" id="{{$friend}}" value="{{$friend}}">
@endforeach
In my controller, I would like to get the values for the checked boxes and put them in an array. I am not exactly sure how to do this, but I assume it is something like:
在我的控制器中,我想获取复选框的值并将它们放入一个数组中。我不完全确定如何做到这一点,但我认为它是这样的:
array[];
foreach($friend as $x)
if (isset(Input::get('friend')) {
array[] = Input::get('friend');
}
endforeach
Could you provide me with a solution to do this? Thank you.
你能给我提供一个解决方案来做到这一点吗?谢谢你。

This is what I have in the controller:
这是我在控制器中的内容:
public function describe_favorite() {
$fan = Fan::find(Auth::user()->id);
$fan->favorite_venue = Input::get('venue');
$fan->favorite_experience = Input::get('experience');
$friends_checked = Input::get('friend[]');
print_r($friends_checked);
if(is_array($friends_checked))
{
$fan->experience_friends = 5;
}
$fan->save();
return Redirect::to('fans/home');
}
It is not going through the "if" loop. How do I see the output of the print_r to see what's in the $friends_checked variable?
它没有通过“if”循环。如何查看 print_r 的输出以查看 $friends_checked 变量中的内容?

If checkboxes are related then you should use [] in the name attribute.
如果复选框是相关的,那么您应该在 name 属性中使用 []。
@foreach ($friends as $friend)
<input tabindex="1" type="checkbox" name="friend[]" id="{{$friend}}" value="{{$friend}}">
@endforeach
$friends_checked = Input::get('friend');
if(is_array($friends_checked))
{
// do stuff with checked friends
}

The array friend must have a key . If there is $friend->id you could try something like this.
数组朋友必须有一个 key 。如果有 $friend->id 你可以尝试这样的事情。
@foreach ($friends as $friend)
<input tabindex="1" type="checkbox" name="friend[{{$friend->id}}]" id="{{$friend}}">
@endforeach

Using name="friend[]" in the form field creates an array named friend that is passed to the server, as opposed to name="friend" which passes a string value to the server.
在表单字段中使用 name="friend[]" 会创建一个名为 friend 的数组,该数组将传递给服务器,而不是 name="friend" 将字符串值传递给服务器。
