Download files in laravel using Response::download

Question

In Laravel application I'm trying to achieve a button inside view that can allow user to download file without navigating to any other view or route Now I have two issues: (1) below function throwing

The file "/public/download/info.pdf" does not exist 

(2) Download button should not navigate user to anywhere and rather just download files on a same view, My current settings, routing a view to '/download'

Here is how Im trying to achieve:

Button:

  <a href="/download" class="btn btn-large pull-right"><i class="icon-download-alt"> </i> Download Brochure </a> 

Route :

Route::get('/download', 'HomeController@getDownload'); 

Controller :

public function getDownload(){         //PDF file is stored under project/public/download/info.pdf         $file="./download/info.pdf";         return Response::download($file); } 

Answer 1

Try this.

public function getDownload() {     //PDF file is stored under project/public/download/info.pdf     $file= public_path(). "/download/info.pdf";      $headers = array(               'Content-Type: application/pdf',             );      return Response::download($file, 'filename.pdf', $headers); } 

"./download/info.pdf"will not work as you have to give full physical path.

Update 20/05/2016

Laravel 5, 5.1, 5.2 or 5.* users can use the following method instead of Response facade. However, my previous answer will work for both Laravel 4 or 5. (the $header array structure change to associative array =>- the colon after 'Content-Type' was deleted - if we don't do those changes then headers will be added in wrong way: the name of header wil be number started from 0,1,...)

$headers = [               'Content-Type' => 'application/pdf',            ];  return response()->download($file, 'filename.pdf', $headers); 

Answer 2

File downloads are super simple in Laravel 5.

As @Ashwani mentioned Laravel 5 allows file downloads with response()->download() to return file for download. We no longer need to mess with any headers. To return a file we simply:

return response()->download(public_path('file_path/from_public_dir.pdf')); 

from within the controller.

Reusable Download Route/Controller

Now let's make a reusable file download route and controller so we can server up any file in our public/files directory.

Create the controller:

php artisan make:controller --plain DownloadsController 

Create the route in app/Http/routes.php:

Route::get('/download/{file}', 'DownloadsController@download'); 

Make download method in app/Http/Controllers/DownloadsController:

class DownloadsController extends Controller {   public function download($file_name) {     $file_path = public_path('files/'.$file_name);     return response()->download($file_path);   } } 

Now simply drops some files in the public/files directory and you can server them up by linking to /download/filename.ext:

<a href="/download/filename.ext">File Name</a> // update to your own "filename.ext" 

If you pulled in Laravel Collective's Html package you can use the Html facade:

{!! Html::link('download/filename.ext', 'File Name') !!}
