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);
