Symfony2 KnpLabsGaufrette - Get local filesystem per twig (downloadable files) - php

Question

i'm using this config.yml.
knp_gaufrette:
adapters:
uploaded_files:
local:
directory: "%kernel.root_dir%/../web/uploads"
create: true
filesystems:
uploaded_files:
adapter: uploaded_files
alias: uploaded_files
Now i want to access uploaded files per twig.
Also for example:
<a href="{{ path('gaufrette_download', {system: 'uploaded_files', file: 'test.txt'}) }}>{{ 'Download' | trans }}</a>
The file should have a path like...
http://localhost/web/uploads/test.txt
I want a direct access to the file(s).
No controller (action).
Is this possible? Any ideas?

Answer 1

If your folder is web-accessible (i.e. you can type the url http://localhost/web/uploads/test.txt in your address bar and download the file), all you have to do is map the route gaufrette_download to that path. Your bundle's routing.yml could look like this (notice the missing defaults: { controller: ... }):
gaufrette_download:
path: /web/uploads/{file}
If your .htaccess is defined properly your web server should serve the file instead of accessing your application. You might have to add requirements for file, e.g. to allow for slashes (search the symfony cookbook for this)
If you just want to skip writing a controller (action), you could just as well create an event listener which is triggered when your request matches the route.
