looking for new maintainer(s) Please use Nette\Application\Responses\FileResponse instead. Or hi-speed solution X-Accel/NGINX or X-Sendfile/Apache.
Addon makes controlled downloads of files peace of cake. It supports client reconnections, segmented downloading, files over 4GB, automatic mime-type detection and special characters in file names. If you need to control download speed you are on the right site.

Install this addon just by calling:
composer require jkuchar/filedownloader
Or to install example, continue to example repository. (one command set-up)
Import FileDownloader from it's namespace
use FileDownloader\FileDownload;And use
$filedownload = new FileDownload;
$filedownload->sourceFile = "source.txt";
$filedownload->download();
// or the same thing using fluent-interface
FileDownload::getInstance()
->setSourceFile("source.txt")
->download();$filedownload = new FileDownload();
$filedownload->sourceFile = "source.txt";
// apply speed limit (in this case in bytes per second)
$filedownload->speedLimit = 5 * FDTools::BYTE;
// set filename that will be seen by user
$filedownload->transferFileName = "test.txt";
// set mime-type manually (you normally do not need to so this!)
$filedownload->mimeType = "application/pdf";
// show this file directly in browser (do not download it)
$filedownload->contentDisposition = FileDownload::CONTENT_DISPOSITION_INLINE;
$filedownload->download();The same thing using fluent-interface:
FileDownload::getInstance()
->setSourceFile("source.txt")
// Nastavíme rychlost odesílání v bytech
->setSpeedLimit(5*FDTools::BYTE)
->setTransferFileName("test.txt")
->setMimeType("application/pdf")
->setContentDisposition(
FileDownload::CONTENT_DISPOSITION_INLINE
)
->download();When... ...download is cancelled ...download failed ...download succeded etc.
$filedownload->onAbort[] = "onAbortHandlerFunction"; // here is everything callable accepted
// fluent-interface
FileDownload::getInstance()->addAbortCallback("onAbortHandlerFunction")
// Callback parameters are always the same
function onAbort(FileDownload $download,IDownloader $downloader){
/* ... */
}| Callback name | Description |
|---|---|
| BeforeDownloaderStarts | Before downloader starts |
| BeforeOutputStarts | Before output to browser starts (last chance to modify HTTP headers) |
| StatusChange | When file download status changes (when block of file is sent or every second if there is no speed limit) |
| Complete | When file download is finished |
| Abort | When file download is aborted (user clicks cancel) |
| ConnectionLost | When connection is lost (for whatever reason) |
| TransferContinue | When paused transfer continues (this is start event for partial downloads) |
| NewTransferStart | When new transfer from beginning starts (this is start event for downloads from beginning) |
In repository there is example form that prints on screen all called callbacks.
There are two downloaders AdvancedDownloader requires to set infinite time limit (tries to do so automatically). As fallback there is NativePHPDownloader available, this downloader requires as much memory as is file size on some PHP installtions. (php bug: if you've found solution, please let me know)
Callbacks, speed controlling and support for big files is only for AdvancedFileDownloader!
- This is realized through cURL extension so please do not forget to enable it. Addon will work also without CURL but very inefficiently.
- Support for >4GB files also requires to add BigFileTools into your libraries (do that using composer)
