Why does $variables in the headers don't work ?

[infowire]

Hello, i have a question, why do my variables $ don't work here? How to get them to work ?

if(isset($_POST['click']))
{
header('Content-Description: File Transfer');
header('Content-Type: application/octet-stream');
header("Content-Disposition: attachment; filename=" . $orig);
header('Content-Transfer-Encoding: binary');
header('Expires: 0');
header('Cache-Control: must-revalidate');
header('Pragma: public');
echo $link_download;
ob_clean();
flush();

 echo file_get_contents($link_download);
};

*sigh* Can you be a bit more specific than “doesn't work”? Have you printed the variable content to see if it's even correct?

 

According to the HTTP standard, the filename must be quoted. As in:

Content-Disposition: attachment; filename="foo"

Firefox seems to happily accept unquoted filenames, but it will stop after the first space character.

i found the first problem, my stupidity. Calling for $ when they have not been defined yet. Now it downloads example.jpg and it can't display...

When you have the browser download a file, it is not going to treat it like a standard image.  Any such handling would be left to the operating system.
