laravel 4從不同文件夾下載文件

Question

嗨，夥計們，我只需要在我的項目下載頁面上獲得一些幫助，因爲我需要一個下載頁面，可以從不同文件夾獲取文件，所有文件夾都在公共路徑中一些想法，我正在使用一個頁面就像下面的鏈接只是忽略其他按鈕。

Download Page

我只是想阿賈克斯這一點，但它不工作

這是我的觀點：

@include('partials.navbar')

$(function() { 
$(".dload-button").click(function(){ 
    var param = $(this).data('id'); 
    $.ajax({ 
     url: "/downloadfile/" + param, 
     success: function(msg){ 
      var dload = JSON.parse(msg)[0]; 
      console.log(dload) 
      $('#id').val(dload.id); 
      $('#type').val(dload.file_type);

     }, 
     error:function(){ 
      alert("failure"); 
     } 
    }); 
    }); 
}); 

我的控制器：

public function dloadFile($id) 
    { 
     $files = Files::where('id',$id) 
        ->get(); 
     return json_encode($files); 
    } 

    public function getDownload() 
    { 
     $id = Input::get('id'); 
     $files = Files::where('id',$id) 
        ->first(); 
     $ftype = $files->file_type = Input::get('type'); 
     $filename = $files->upload = Input::file('filename'); 
     $file= public_path(). "uploads/{$ftype}"; 

     $headers = array(
       'Content-Type: => application/pdf', 
      ); 

     return Response::download($file, '{$filename}', $headers); 


    } 

我的路線：

Route::get('/downloadfile/{id}', 'FileController@dloadFile'); 
Route::get('/download', array('uses' => 'FileController@getDownload')); 

任何想法更多讚賞先謝謝了！

Answer 1

有沒有必要使用Ajax進行下載。有我的代碼下載產品image.in視圖文件有下載鏈接。

<a data-id="{{ $product->id }}" href="/productCRUD/{{$product->id}}/download" class="btn btn-primary btn-xs dload-button" ><i class="fa fa-download">Download</i></a> 

在routes.php文件

Route::get('productCRUD/{product}/download', 'ProductCRUDController@download'); 

在productCRUDController.php

public function download($id) 
{ 

    $files = Product::where('id',$id) 
       ->first(); 
    $ftype = $files->file_type = Input::get('type'); 
    $fullPath= public_path(). "/uploads/{$files->filePath}"; 
    $headers = array(
      'Content-Type: => application/jpg', 
     ); 
    return Response::download($fullPath,$files->filePath, $headers); 

} 

與當你點擊你在你的下載文件夾中的文件下載鏈接此代碼。
