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);
}
This question is related to

laravel-routing
HTML href link click:
<a ="{{ route('download',$name->file) }}"> Download </a>
In controller:
public function download($file){
$file_path = public_path('uploads/cv/'.$file);
return response()->download( $file_path);
}
In route:
Route::get('/download/{file}','Controller@download')->name('download');
HTML link click
<a class="download" href="{{route('project.download',$post->id)}}">DOWNLOAD</a>
// Route
Route::group(['middleware'=>['auth']], function(){
Route::get('file-download/{id}', 'PostController@downloadproject')->name('project.download');
});
public function downloadproject($id) {
$book_cover = Post::where('id', $id)->firstOrFail();
$path = public_path(). '/storage/uploads/zip/'. $book_cover->zip;
return response()->download($path, $book_cover
->original_filename, ['Content-Type' => $book_cover->mime]);
}
In the accepted answer, for Laravel 4 the headers array is constructed incorrectly. Use:
$headers = array(
'Content-Type' => 'application/pdf',
);
While using laravel 5
use this code as you don`t need headers.
return response()->download($pathToFile);
.
If you are using Fileentry
you can use below function for downloading.
// download file
public function download($fileId){
$entry = Fileentry::where('file_id', '=', $fileId)->firstOrFail();
$pathToFile=storage_path()."/app/".$entry->filename;
return response()->download($pathToFile);
}
File downloads are super simple in Laravel 5.
As @Ashwani mentioned Laravel 5 allows file downloads with response()->download()
to return file for download. We no longer need to mess with any headers. To return a file we simply:
return response()->download(public_path('file_path/from_public_dir.pdf'));
from within the controller.
Reusable Download Route/Controller
Now let's make a reusable file download route and controller so we can server up any file in our public/files
directory.
Create the controller:
php artisan make:controller --plain DownloadsController
Create the route in app/Http/routes.php
:
Route::get('/download/{file}', 'DownloadsController@download');
Make download method in app/Http/Controllers/DownloadsController
:
class DownloadsController extends Controller
{
public function download($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') !!}
If you want to use the JavaScript download functionality then you can also do
<a onclick=“window.open(‘info.pdf) class="btn btn-large pull-right"><i class="icon-download-alt"> </i> Download Brochure </a>
Also remember to paste the info.pdf file in your public directory of your project
I think that you can use
$file= public_path(). "/download/info.pdf";
$headers = array(
'Content-Type: ' . mime_content_type( $file ),
);
With this you be sure that is a pdf.
// Try this to download any file. laravel 5.*
// you need to use facade "use Illuminate\Http\Response;"
public function getDownload()
{
//PDF file is stored under project/public/download/info.pdf
$file= public_path(). "/download/info.pdf";
return response()->download($file);
}
This is html part
<a href="{{route('download',$details->report_id)}}" type="button" class="btn btn-primary download" data-report_id="{{$details->report_id}}" >Download</a>
This is Route :
Route::get('/download/{id}', 'users\UserController@getDownload')->name('download')->middleware('auth');
This is function :
public function getDownload(Request $request,$id)
{
$file= public_path(). "/pdf/"; //path of your directory
$headers = array(
'Content-Type: application/pdf',
);
return Response::download($file.$pdfName, 'filename.pdf', $headers);
}
Quite a few of these solutions suggest referencing the public_path() of the Laravel application in order to locate the file. Sometimes you'll want to control access to the file or offer real-time monitoring of the file. In this case, you'll want to keep the directory private and limit access by a method in a controller class. The following method should help with this:
public function show(Request $request, File $file) {
// Perform validation/authentication/auditing logic on the request
// Fire off any events or notifiations (if applicable)
return response()->download(storage_path('app/' . $file->location));
}
There are other paths that you could use as well, described on Laravel's helper functions documentation
you can use simply inside your controller:
return response()->download($filePath);
Happy coding :)
