force download of different files [closed]

Answer 1

You can try something like where the links to the image downalod.php?img=sterling02

$image = isset($_GET['img']) ? $_GET['img']  : "noimage" ;
$image .= ".jpg";

header('Content-disposition: attachment; filename='.$image);
header('Content-Type: image/jpeg');
readfile($image);

But if you want to force the download then use

header("Pragma: public");
header("Expires: 0");
header("Cache-Control: must-revalidate, post-check=0, pre-check=0"); 
header("Content-Type: application/force-download");
header("Content-Type: application/octet-stream");
header("Content-Type: application/download");
header("Content-Transfer-Encoding: binary ");
header('Content-disposition: attachment; filename='.$image);
readfile($image);

Answer 2

Your content-types are incorrect. You have to provide the file's mime type, which would be image/jpeg. not image.jpg.

As well, you cannot force a download of 3 separate files in a single HTTP request. While some browsers do support multiple files, you must encapsulate each one in a separate MIME body block, which you are not doing.

Either provide a .zipped copy of these 3 files for a single download, or provide 3 separate download links, one file per link.

Answer 3

Set the choice in the query string download.php?option=1

if (!isset($_REQUEST['option']) {
   //redirect away
}
if ($_REQUEST['option'] == 1) {
   header(...)
   //sterling02md.jpg
}
