Upload

To upload files there is the UploaderInterface. The UploaderInterface just returns an instance of File that provides a path for the file.

Config

Config Name	Example	Required	Description
provider	s3	true	The mailing service to be used. Options are: null, sendgrid, mailgun, postmark
naming_strategy	random_time	true
s3	n/a	false	The S3 options as defined in the AWS S3 section below.
local	n/a	false	The local options as defined in the local section below.
url	https://public.url/	true	The base url the file will be located at.

Fetching an Uploader

To get the uploader you can just autowire Parthenon\Common\Upload\UploaderInterface. And that will inject either the uploader called default or if there is only one it'll inject that.

{{% notice info %}} If you have more than one uploader and neither are called default. Autowiring will result in an exception for no found uploader being flung. {{% /notice %}}

The other way to get the uploader is to call the Parthenon\Common\Upload\UploaderManager::getUploader. This can be injected via autowiring with the interface Parthenon\Common\Upload\UploaderManagerInterface.

use Parthenon\Common\Upload\UploadManager;

class Controller {
    public function uploadAction(Request $request, UploaderManagerInterface $uploaderManager) {
      $uploader = $uploaderManager->getUploader('profile_images');
      // do stuff with uploader
    }
}

Creating your own uploader

namespace Parthenon\Common\Upload;

use Symfony\Component\HttpFoundation\File\UploadedFile;

interface UploaderInterface
{
    public function uploadUploadedFile(UploadedFile $file): File;
}

Naming

Often there is a need for files to be named in a specific way.

namespace Parthenon\Common\Upload;

interface NamingStrategyInterface
{
    public function getName(string $filename): string;
}

Strategies

Name	Description
md5_time	This creates a md5 hash from the file name and then suffixes a unix timestamp to the end. This does result in a guessable filename.
random_time	This this creates a random string that has the timestamp suffixed to it.

Flysystem

Flysystem is an extremely good uploading library that can be used for upload files to multiple systems. There is a wrapper for his library to allow use while also allowing for potential competitors in the future to be usable.
