当在另一个函数中访问会话时会话变为空

Question

我正在使用laravel框架5.2。我正在使用dropzone处理多个图像。所有图像都成功存储在会话中。现在的问题是，当我在另一个函数访问特定的会话它给了我空白的结果，这里是我巴尔德文件和功能

enter code here 
<---Dropzone--> 
<div class="modal-body"> 
      <div class="dropzone-img"> 
       <form id="my-awesome-dropzone" action="{{ url('/add-images')}}" class="fallback dropzone"> 
          {{ csrf_field() }} 

      </div> 
     </div> 

现在我的控制器有两个功能

enter code here 
public function add_images(Request $request){ 
    if($request->ajax()){ 
     $image=$_FILES['file']; 
     if(!empty($image)){ 
      if($image['error']==0){ 
       $imgName = pathinfo($_FILES['file']['name']); 
       $ext = $imgName['extension']; 
       $rand=mt_rand(5,1000000000).'.'.$ext; 
       $destination=realpath('../public/images/ListingImages').'/'; 
       if(move_uploaded_file($image['tmp_name'], $destination.$rand)){ 
        $request->session()->put('businessimages.'.$imgName['filename'].'.image',$rand); 
        $images = $request->session()->get('businessimages'); 
        echo "<pre>"; print_r($images); die; 
       } 
      } 
     } 
    } 
} 

Now when i accessed the businessimages session in another function it gives me empty result. 

public function business_for_sale(Request $request){ 
    $images = $request->session()->get('businessimages'); 
    echo "<pre>"; print_r($images); die; 
} 

谁能帮我。感谢提前:)

我认为这个问题是你调用die（）函数，当你设置会话

$request->session()->put('businessimages.'.$imgName['filename'].'.image',$rand); 
$images = $request->session()->get('businessimages'); 
echo "<pre>"; print_r($images); die; 

你可以看到它 Does die() end your session in PHP?

所以，你可以尝试改变它像

$request->session()->put('businessimages',$rand); 
$images = $request->session()->get('businessimages'); 
echo "<pre>"; print_r($images); 
session_register_shutdown(); 
die;
