如何获取Laravel 4控制器中的一系列复选框的值（如果选中） [英] How to get the values for a series of checkboxes in Laravel 4 controller (if checked)

问题描述

我想获取我在Laravel 4表单中设置的一系列复选框的值。下面是视图中的代码设置复选框：

  @foreach（$ friends为$ friend）
 ; input tabindex =1type =checkboxname =friend []id ={{$ friend}}value ={{$ friend}}> 
 @endforeach 
  

在我的控制器中，我想获取复选框的值并将它们放在数组中。我不知道如何做到这一点，但我认为是这样的：

  array []; 
 
 foreach（$ friend as $ x）
 if（isset（Input :: get（'friend'））{
 array [] = Input :: get '）; 
 
} 
 endforeach 
  

编辑：

这是我在控制器中的：

  public function describe_favorite（）{
 
 $ fan = user（） - > id）; 
 $ fan-> favorite_venue = Input :: get（'venue'）; 
 $ fan-> favorite_experience = Input :: get ; 
 
 $ 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'）; 
 
} 
  

它不是通过if循环。如何查看print_r的输出以查看$ friends_checked变量中的内容？

解决方案

如果复选框相关，则应在name属性中使用[]。

  @foreach（$ friends as $ friend）
< input tabindex =1type =checkboxname =friend []id = {{$ friend}}value ={{$ friend}}> 
 @endforeach 
 
 
 $ friends_checked = Input :: get（'friend'）; 
 if（is_array（$ friends_checked））
 {
 //与选中的朋友做朋友
} 
  

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:

@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:

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.

EDIT:

This is what I have in the controller:

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?

解决方案

If checkboxes are related then you should use [] in the name attribute.

@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
}
