Download function - El Forum - 03-27-2013

Hi,
I would really appreciate if someone can give a few pointers here. I have in my controller a download function which looks like this:
Code:
public function download($file_name){
$mime = 'application/vnd.google-earth.kmz';
$path = $_SERVER['DOCUMENT_ROOT']."/trackdb/modules/gis/assets/archive/";
$full_name = $path.$file_name;
echo($full_name);
header('Content-Type: '.$mime);
header("Content-Disposition: attachment; filename=$file_name");
header("Pragma: no-cache");
header("Expires: 0");
readfile("$full_name");
exit();
}In my view, I have:
Code:
echo anchor('gis/download/'.$result, 'Download KMZ file', 'title="KMZ File"');$result is the file name passed from the controller.
The generated URL of the link looks like:
http://{Domain}/trackdb/index.php/gis/download/Sites.kmz
Which is the correct file name. The problem is that the file doesn't actually download. It simply downloads a dummy 1 KB .kmz file (the real file in that location is over 2MB).
Many thanks
Jad

I've tried using the download helper instead. The message I kept getting is:
Message: file_get_contents(path...) [function.file-get-contents]: failed to open stream: No such file or directory
The problem is that I've tried everything with path, writing it as a relative path, absolute path...etc. and I still keep getting the message.
Code:
public function download($file_name){
$path = '../assets/archive/';
$this->load->helper('download');
$data = file_get_contents($path.$file_name);
force_download($file_name, $data );

Solved.
Path has to be specified relative to index.php file, not the controller.

Welcome to the CodeIgniter forums!
I'm glad you solved your problem.
It's a good idea to always use absolute paths wherever possible. There are some built-in constants to help with that.
Code:
BASEPATH // The path to the ./system directory.
APPPATH // The path to the ./application directory.
FCPATH // The path to the directory containing your index.php file.
