問題描述

我想獲取我在 Laravel 4 表單中設置的一系列復選框的值.這是視圖中設置復選框的代碼:

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

在我的控制器中，我想獲取復選框的值并將它們放入一個數組中.我不完全確定如何做到這一點，但我認為它是這樣的:

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

你能為我提供一個解決方案嗎?謝謝你.

Could you provide me with a solution to do this? Thank you.

這是我在控制器中的內容:

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');

        }

它沒有通過if"循環.如何查看 print_r 的輸出以查看 $friends_checked 變量中的內容?

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?

推薦答案

如果復選框是相關的，那么你應該在 name 屬性中使用 [].

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
}
