symfony: stream download

by prettyscripts on 2010-05-17 10:42:06

to download file the symfony way, add a download action and not to display layout unless there are errors.

in /path/to/your/app/modules/your_module/actions/actions.class.php:

PHP:

	`public function executeDownload(sfWebRequest $request) {`
	`$file = Doctrine::getTable('File')->find($request->getParameter('id'));`

	`// check if file exists`
	`if (!$file->fileUploaded()) {`
	`$this->getUser()->setFlash('error', 'File does not exist.');`
	`return sfView::ERROR;`
	`}`

	`// do any file information formatting`
	`// do any credential validation`

	`// dowload file`
	`$response = $this->getContext()->getResponse();`
	`$response->clearHttpHeaders();`
	`$response->addCacheControlHttpHeader('Cache-control', 'must-revalidate, post-check=0, pre-check=0');`
	`$response->setContentType('application/octet-stream', true);`
	`$response->setHttpHeader('Content-transfer-encoding', 'binary');`
	`$response->setHttpHeader('Content-Disposition', 'attachement; filename=' . $file->getSlug() . '.' . $file->getExtension());`
	`$response->sendHttpHeaders();`
	`$response->setContent(file_get_contents($file->getFullPathFilename()));`

	`return sfView::NONE;`
	`}`
