Here is trimmed down version of what I have for a file download function. In
my version the filename is generated by the action params, you would have
customize that part to your setup. Content Type would also have to be
modified, as they are getting pdf files this setup.
Maybe it will help.
public function downloadAction () {
// path to file
$timage = "/generate/real/path/to/file/";
// break file up
$tp = pathinfo($timage);
// disable mvx layout
Zend_Layout::getMvcInstance()->disableLayout();
// disable this view
$this->_helper->viewRenderer->setNoRender();
// set headers
header("Content-Type: application/pdf");
header("Content-disposition: attachment;
filename=".$tp['basename'].";");
header("Content-Length: ".filesize($timage));
header('Content-Transfer-Encoding: Binary');
header('Accept-Ranges: bytes');
header('ETag: "'.md5($timage).'"');
header("Cache-Control: no-cache, must-revalidate");
header("Pragma: no-cache");
//send file data
// or print file_get_contents($timage);
readfile_chunked($timage);
}
// pulled from php.net comments
function readfile_chunked($filename,$retbytes=true) {
$chunksize = 15*1024; // how many bytes per chunk
$buffer = '';
$cnt =0;
// $handle = fopen($filename, 'rb');
$handle = fopen($filename, 'rb');
if ($handle === false) {
return false;
}
while (!feof($handle)) {
$buffer = fread($handle, $chunksize);
echo $buffer;
ob_flush();
flush();
if ($retbytes) {
$cnt += strlen($buffer);
}
unset($buffer);
}
$status = fclose($handle);
if ($retbytes && $status) {
return $cnt; // return num. bytes delivered like readfile()
does.
}
return $status;
}

Subject: Re: [fw-general] Action Helper To Send Files?
Should these callback functions be added to the action controller? Or added
as new methods of a class extending ContextSwitch?
