[PHP] How to ensure cookies are turned on.
Hello; Im working on a website that uses sessions as an integral part of the site. If cookies are not turned on in the browser, my site will not work. Ive been searching unsuccessfully to find the way to determine if the browser has cookies enabled. I want to warn the user that the site wont work if they have cookies turned off. There must be some global variable that tells me. Could someone help me out?

You can redirect user to a turn on your cookies page at a point where cookies are really required and none is send. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php

There is no global variable.
Set a cookie the when they hit the login page and then check to be sure that
cookie isset when they post to it.
Example for login.php:
?
setcookie(cookie_check,1);
if ($LoginButton == Login){
if ($cookie_check != 1){
header (Location: no_cookies.php);
exit;
}
# THE BALANCE OF YOUR SCRIPT - If they got here they have cookies enabled.
}
?
form method=post action=?= $PHP_SELF ?
!-- THE BALANCE OF YOUR FORM --
/form
Best,

If the cookie you set is not send back, the cookies are turned off
(unless you screwed up). You can redirect user to a turn on your
cookies page at a point where cookies are really required and none is
send.
and how would you know that? unless you specify an alternative string
using GET ofcourse
By where cookies are really required I meant for example login page.
If you find out that session cookie is not set while handling login
form, you know that cookies are off.
The alternative you are talking about is also possible, but you have to
be carefull so that these pages are not indexed by search engines.
