[SOLVED] $_session problem

[johnsmith153]

Does anyone have a script that allows a user to download a file but have some sort of session control?

 

Ie

 

if($_SESSION['a']==1)

{

//download

}

else

{

//do not download

}

 

etc.

 

must work with sessions - which seems to be the problem.

have a script set a session, then do this

<?php
session_start();
if ($_SESSION['download']) {
echo '<script type="text/javascript">document.location="download link.exe"</script>';
}
?>

[johnsmith153]

I need it without javascript.

 

Is that possible?

[waynew]

<?php
session_start();
if ($_SESSION['download']) {
   header('Location: filename.exe');
}
?>

 

[jjacquay712]

sure, you can use this:

<?php
session_start();
if ($_SESSION['download']) {
header("location: download_link.exe");
}
?>

[jjacquay712]

beat me to it

[johnsmith153]

<?php
session_start();
if ($_SESSION['download']) {
header("location: jpeg-image.jpg");
}
?>

 

jpeg-image.jpg

 

Hardly going to work though, is it?

[johnsmith153]

Any ideas anyone?

 

Need to download a file, NOT just link to it.

 

But must be able to use $_SESSION on the page - it seems to mess it up if you do.

Sessions have nothing to do with opening files, so not sure what you mean by "mess up".

<?php
session_start();
if ($_SESSION['download']) {
header('Content-Disposition: attachment; filename="file.ext"'); 
readfile('path/to/file.ext');
}
?>

I agree there should not be any relation between file download and $_SESSION, but:

 

The below scripts are the full code that is on the page.

 

This WORKS great:

//session_start();
$fileurl = "/home/account/folder1/folder2/file.xlsx";
$file= "file.xlsx";
header("Content-Disposition: attachment; filename=$file");
readfile($fileurl);

 

This DOES NOT:

session_start();
$fileurl = "/home/account/folder1/folder2/file.xlsx";
$file= "file.xlsx";
header("Content-Disposition: attachment; filename=$file");
readfile($fileurl);

[revraz]

Define DOES NOT.  What does or does it not do?

[johnsmith153]

It does not work. It does not do the file download.

[johnsmith153]

Surely either I'm the idiot, or PHP is. Which one?

 

I would appreciate if someone can try this, I just can not understand why the below script will not download the file just because I set session_start()

 

Works fine, unless you set session_start()

 

//session_start();

$fileurl = "/home/account/folder1/folder2/file.xlsx";

$file= "file.xlsx";

header("Content-Disposition: attachment; filename=$file");

readfile($fileurl);

Thanks to www.sitepoint.com, the answer is:

 

Place:

 

session_cache_limiter('public');

 

before the session_start() call
