Drupal: Send file programmatically
User login
Tuesday, July 24, 2012 - 13:08
Here is a handy, general function for Drupal 6 that takes as an argument a file id and returns the file for downloading.
<?php
function MYMODULE_send_file($fid) {
$file = db_fetch_object(db_query("SELECT * FROM {files} WHERE fid = %d", $fid));
if ($file) {
$my_path = $_SERVER['DOCUMENT_ROOT'] .'/'.$file->filepath;
header("Pragma: public");
header("Expires: 0");
header('Cache-Control: no-store, no-cache, must-revalidate');
header('Cache-Control: pre-check=0, post-check=0, max-age=0', false);
header('Last-Modified: '.gmdate('D, d M Y H:i:s') . ' GMT');
$browser = $_SERVER['HTTP_USER_AGENT'];
if(preg_match('/MSIE 5.5/', $browser) || preg_match('/MSIE 6.0/', $browser))
{
header('Pragma: private');
// the c in control is lowercase, didnt work for me with uppercase
header('Cache-control: private, must-revalidate');
// MUST be a number for IE
header("Content-Length: ".filesize($my_path));
header('Content-Type: application/x-download');
header('Content-Disposition: attachment; filename="'.$file->filename.'"');
}
else
{
header("Content-Length: ".(string)(filesize($my_path)));
header('Content-Type: application/x-download');
header('Content-Disposition: attachment; filename="'.$file->filename.'"');
}
header('Content-Transfer-Encoding: binary');
if ($file = fopen($my_path, 'rb')) {
while(!feof($file) and (connection_status()==0))
{
ob_clean();
print fread($file, filesize($my_path));
flush();
}
fclose($file);
}
exit(0);
}
}
