Implements a server-side strategy for collection and recovery of PSR-7 UploadedFile objects

1.0.1 2017-05-06 07:53 UTC


This package implements a server-side strategy for temporary collection and recovery of PSR-7 UploadedFile objects.

PHP Version

You can use this service to implement controllers that collect uploaded files posted asynchronously by a browser and return the temporary file UUIDs, then, on completion, recover the uploaded files and move them to permanent storage.

The filename and MIME-type (as posted by the client) will be preserved.

Unrecovered files are automatically flushed after a defined expiration period.


Bootstrap the service:

$service = new TempFileService(__DIR__ . '/temp');

In your asynchronous file post-controller, collect posted files and return UUIDs:

$uuids = [];

foreach ($request->getUploadedFiles() as $file) {
    $uuids[] = $service->collect($file);

echo json_encode($uuids);

In your form post-controller, recover the collected files:

foreach ($uuids as $uuid) {
    $file = $service->recover($uuid);

    // get information about recovered file:

    $filename = $file->getClientFilename();
    $media_type = $file->getClientMediaType();

    // move recovered file into permanent storage:

    $file->moveTo(__DIR__ . '/files/' . $file->getClientFilename());

Alternatively, obtain the path to the temporary file and move/copy the file by other means - for example, to import an uploaded file into FlySystem:

$file = $service->recover($uuid);

$stream = fopen($file->getTempPath(), "r");

$filesystem->writeStream("uploads/" . $file->getClientFilename(), $stream);


$file->flush(); // optionally flush the temporary file after copying

Note that, if you don't flush the temporary file, it will of course be garbage-collected after the defined expiration period.

Also, if you manually rename or move the temporary file, the JSON meta-data file will be collected and flushed for you immediately when the TempFile instance is destroyed.
