當在另一個函數中訪問會話時會話變爲空

Question

我正在使用laravel框架5.2。我正在使用dropzone處理多個圖像。所有圖像都成功存儲在會話中。現在的問題是，當我在另一個函數訪問特定的會話它給了我空白的結果，這裏是我巴爾德文件和功能

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> 

現在我的控制器有兩個功能

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; 
} 

誰能幫我。感謝提前:)

我認爲這個問題是你調用die（）函數，當你設置會話

$request->session()->put('businessimages.'.$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，你可以嘗試改變它像

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