RE: [fw-general] Downloading a file from server

[Gina-Marie Rollock]

Thanks again Lars. I finally got it to work. Seems that my final problem
was that I wasn't disabling the view, thereby corrupting the output. I
disabled my layout and set the view not to render, and I'm OK now.

Hi Gina-Marie,

You do it in a very similar way as you would do it plain PHP: you send a
header, read the file, send the content of the file. So in a controller
it could looks something like this:

public function downloadAction()
{
    $this->getResponse()->setHeader('Content-Type: foo/bar');
    $filename =
$this->sanitizeFilename($this->getRequest()->getParam('filename'));
    $this->getResponse()->appendBody(file_get_contents($filename));
}

Note: the sanitizeFilename()-method is not present. You must implement
something like this to not introduce security issues where people can
download your /etc/passwd or something similar. But preferably such
validation is done in your domain model.
If you have a model and such file is part of your model, it could
probably look like that:

public function downloadAction()
{
    $model = new
YourDomainModel($this->getRequest()->getParam('filename'));
    $this->getResponse()->setHeader('Content-Type', $model->getType());
    $this->getResponse()->appendBody($model->getContent());
}

cu, Lars
