Problem with uploading files, flow-php-server and Laravel

I ran into a problem of files not being uploaded today using flow-php-server together with Laravel. For me the problem was that the 404 header wasn’t properly returned on the test function of flow.js. Instead it would just return a 200 which in turn caused flow.js to not send the POST request after the GET request to check for the chunk existence.

In Laravel you should do something like this in the controller method that handles the flow.js requests. (taken from the basic example):

if (\Flow\Basic::save('./uploads/name_of_new_file', './chunks_temp_folder')) {
  // file saved successfully and can be accessed at './final_file_destination'
} else {
  // This is not a final chunk or request is invalid, continue to upload.
  $response = Response::make('', 404);
  return $response;
}

When I started I left the else block empty. Now the whole thing makes sense to me, but I haven’t done much backend before, so all in all this took me a couple of hours. I figured maybe posting this here helps someone else.

I am not a laravel user, but the key tasks would be:

• Setup routes, your action should accept GET and POST requests
• Copy https://github.com/flowjs/flow-php-server/blob/master/src/Flow/Basic.php class and make your own one with laravel Response class:

use \Flow\Request;
use \Flow\Config;
use \Flow\File;

$request = new Request();
$config = new Config(array(
   'tempDir' => 'tmp/'
));
$file = new File($config, $request);
$response = Response::make('', 200);

if ($_SERVER['REQUEST_METHOD'] === 'GET') {
    if (!$file->checkChunk()) {
        return Response::make('', 404);
    }
} else {
    if ($file->validateChunk()) {
        $file->saveChunk();
    } else {
        // error, invalid chunk upload request, retry
        return Response::make('', 400);
    }
}
if ($file->validateFile() && $file->save($destination)) {
    $response = Response::make('pass some success message to flow.js', 200);
}
return $response;

You might also pass params to Flow\Request class https://github.com/flowjs/flow-php-server/blob/master/src/Flow/Request.php#L12 Or you can rewrite this class in a laravel way. I haven’t tested this, but it might work.

Laravel way instead of $_SERVER['REQUEST_METHOD'] === 'GET' would be if ($request->isMethod('get')) { } where $request is Illuminate\Http\Request injected into method as Request $request
