Sessions Header

[vccarvalho]

Hi there, I'm new to sessions, and I'm having this message displayed in a few pages, what's funny is that just a few pages shows this warning others work just fine:

Warning: Cannot send session cache limiter - headers already sent (output started at /home/exported/viniciusc/public_html/cpdee_new/adm/blocks/teses_selection.php:2) in ../sessions.php on line 3

I'm using a sessions.php page that's included in every page

session.php

<?
session_id();
session_start();
session_register("sID");
session_register("sUser");
session_register("sPerfil");
session_register("sTipo");

?>

And also have a Check login in every page to check if the $sID session var was set.

Any help would be very nice 🙂

Thanks

Vinicius,

It would appear from the information you have given that in the pages where you receive this error message, you have some characters inserted before you call session_start();

This might include a space, return or whatever. Check that there is nothing before you call the session functions.

This includes before the <?

It would appear that your include page (in your example) is not the problem as you do not get the error evertime you include it. The problem is on the pages you have included this page from.

Hope this helps

You cannot have any white space at the top of the page. If there is any space it may be interpreted as output and the session call will fail.

I'm guessing that on some pages you have a blank line or two before you start the code.

Seesion must be the first thing on the page, headers can be added right after.
