Upload manager for Nette framework



"ondrs/upload-manager": "v8.0.0"


Register the extension:

    uploadManager: ondrs\UploadManager\DI\Extension

Minimal configuration:

    relativePath: '/uploads'

Full configuration:

    basePath: %wwwDir%
    relativePath: '/uploads'
        blacklist: {php}
        maxSize: 1280
        type: jpg
        quality: 80
        saveOriginal: FALSE
                - {800, NULL}
                - shrink_only
                - {500, NULL}
                - shrink_only
                - {250, NULL}
                - shrink_only
                - {100, NULL}
                - shrink_only

In most cases you want to choose the wwwDir as your basePath (and it is chosen by default) to make your files publicly accessible. relativePath is relative to the basePath, so complete path where your files will be uploaded looks like this


dir is an optional parameter and you can set it during the runtime of your script in the listen() or in the upload() method.


  • blacklist
    • array of files extensions which are blacklisted, php is by default


  • maxSize

    • maximum size of an image, if its bigger, it will be automatically resized to this size
    • can be number X coord of an imahe
    • or array [X, Y]
  • dimensions

    • array of dimensions to which an image will be resized

    • format is

          - {X_SIZE, Y_SIZE}
          - RESIZE_OPTION
    • PREFIX can be whatever you want, it will be added to a resized file: PREFIX_file.jpg

    • Y_SIZE is optional as well as RESIZE_OPTION

    • RESIZE_OPTION is set to Image::SHRINK_ONLY by default

For example we will set the UploadManager according to the full configuration which is written above.


Uploading an image file foo.jpg with size (1680 x 1050) will result in creation of 5 files: foo.jpg, 800_foo.jpg, 500_.jpg, 250_foo.jpg, thumb_foo.jpg which will be saved in the %wwwDir%/uploads/super/dir All files are resized proportionally according to their X dimension and saved with a corresponding prefix. File foo.jpg is considered to be an original but it's resized to 1280px.


Inject ondrs\UploadManager\Upload into your presenter or wherever you want

/** @var \ondrs\UploadManager\Upload @inject
public $upload;

And do an upload.

public function renderUpload()

If you want to upload just a single file (for example with a form) call the singleFileToDir() method

public function processForm($form)
    /** @var Nette\Http\FileUpload */
    $fileUpload = $form->values->file;

    $this->upload->singleFileToDir('path/to/dir', $fileUpload);


The real fun comes up with an events. They are here to help you to control and monitor your upload process with an ease.

  • onQueueBegin

    • called before the upload starts
    • accept one argument
      1. array of Nette\Http\FileUpload objects which will be uploaded
  • onQueueComplete

    • called when the upload finish
    • accept two arguments
      1. array of Nette\Http\FileUpload
      2. array of \SplFileInfo objects which were uploaded
  • onFileBegin

    • called before the upload of each file
    • accept two arguments
      1. Nette\Http\FileUpload
      2. dir which is constructed as {relativePath}[/{dir}]
  • onFileComplete

    • called after the upload complete of each file
    • accept three arguments
      1. Nette\Http\FileUpload object of the original file
      2. \SplFileInfo object of the uploaded file
      3. dir which is constructed as {relativePath}[/{dir}]

Real world example

 * @param int $eventId
public function uploadAttachment($eventId)
     * @param FileUpload $fileUpload
     * @param \SplFileInfo $uploadedFile
     * @param $path
    $this->upload->onFileComplete[] = function (\SplFileInfo $uploadedFile, FileUpload $fileUpload, $path) use ($eventId) {

        $filename = $uploadedFile->getFilename();

                'filename' => $filename,
                'path' => $path,
                'crm_events_id' => $eventId,

     * @param array $files
     * @param array $uploadedFiles
    $this->upload->onQueueComplete[] = function(array $files, array $uploadedFiles) use($eventId) {

        $uploadedFiles = array_map(function($i) {
            return $i->getFilename();
        }, $uploadedFiles);

                'text' => implode(';', $uploadedFiles),

    $this->upload->filesToDir('attachments/' . $eventId);
