Download File In Laravel

- 1 answer

I am new to Laravel and I trying to capture the filename stored on the database table called "Infrastructure" so that I can create a link for users to downloading that file. The download works but I always get the wrong file stored in the directory.

So in my controller called infrastructureController.php I have these codes.

public function show($id)
    {
        $infrastructure = $this->infrastructureRepository->find($id);
        $Attachment = $infrastructure->inf_file; // captured filename in the database

        if (empty($infrastructure)) {
            Flash::error('Infrastructure not found');

            return redirect(route('infrastructures.index'));
        }

        return view('infrastructures.show')->with('infrastructure', $infrastructure);
    }

In my route or web.php

I have these codes...

Route::get('/download', function(){
    $name = $Attachment;

    $file = storage_path()."/app/public/infrastructure/".$Attachment;

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

    return Response::download($file, $name, $headers);
});

and finally, in my view file, I have this

<!-- Inf File Field   -->
<div class="form-group">
    {!! Form::label('inf_file', 'Attachements:') !!}
    <a target="_blank" rel="nofollow noreferrer" href="/download">Download Now</a>
</div>

Can someone point out I did wrong here...

Answer

First you are not passing the name of the attachment from your View back to your controller so change your view to:

<!-- Inf File Field   -->
<div class="form-group">
    {!! Form::label('inf_file', 'Attachements:') !!}
    <a target="_blank" rel="nofollow noreferrer" href="/download/{{ $infrastructure->inf_file }}">Download Now</a>
</div>

Then in your route you need to access the name of the file like so:

Route::get('/download/{Attachment}', function($Attachment){
    $name = $Attachment;

    $file = Storage::disk('public')->get("infrastructure/".$Attachment);

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

    return Response::download($file, $name, $headers);
});
