Apache ErrorDocument and $_SESSION vars

[Eric_S]

Hi,

 

In my ErrorDocument I'd like to be able to set some variables for future use then redirect using header() and access them.

 

.htaccess has this entry in it: ErrorDocument 404 /error.php

 

I can pass variables in cookies and all works:

 

setcookie('my_var', 'my_val');

header ("Location: $url");

 

I would rather set $_SESSION variables but I can't get it to work.

 

session_start();

$_SESSION['my_var'] = 'my_val';

header ("Location: $url");

 

then...

 

echo $_SESSION['my_var']; returns "". This works fine from other php scripts but not from ErrorDocument. What am I doing wrong here?

 

.htaccess has this in it:

 

ErrorDocument 404 /error.php

 

TIA.

The session is not getting passed to the next page. Any ideas?

[MasterACE14]

do you have session_start(); at the top of the 'next page' ?

[Eric_S]

Yes, it's there on both pages.

You have to close the session before doing the redirect. This ensures the session is written to before the next page is served.

 

session_write_close is probably the best idea.

Tried that too. I figured out the session_id changes but how can I grab the one from the last page or keep that session in the first place? I can pass the session_id in the query string but that's ugly. I can use cookies too and that works but sessions or post would be best.
