[PHP] Must Have Cookies. PHP/JavaScript
OK, I'm working on a site that absolutely must use a cookie containing a session identifier. I know how to set a cookie through PHP, but I need to do something else too. The same page MUST identifier whether the cookie was accepted or not. I've seen sites like NetFlix.com that will test to see if their cookie was accepted, and if not, print up a page that says Sorry, you've got have your Cookies on or go somewhere else. Does anyone know how to do this with PHP, Java, or JavaScript? Code examples or example URLs would be appreciated.

RE: [PHP] Must Have Cookies. PHP/JavaScript
On the *2nd* page request you can check for your cookie in
$HTTP_COOKIE_VARS. If it is not there, cookies are disabled in the browser.
Here's a kludge to make your first page the 2nd page request: just start
your session on index, then META redirect to the next page; this 2nd page is
where you actually output HTML to the browser, and also check for the
cookie.
function check_cookies() {
global $HTTP_COOKIE_VARS;
if(!$HTTP_COOKIE_VARS[PHPSESSID]) {
// redirect to the cookie error page;
exit();
}

Not to sound overly obvious, but try this.
setcookie(cookieusername,$username,time()+6048000,/,,0);
$cookieusername = $HTTP_COOKIE_VARS[cookieusername];
if (!$cookieusername){
echoSorry, no cookie, no page.;
die();
}

If you won't enable trans_sid, you'll only have cookie based session, so
on each page you can test for cookie presence in $HTTP_COOKIE_VARS global
array, or, if you have register_globals on (practice for newbies), in
$GLOBALS.
So, you'll supposedly have an entrance page:
[index.php]
?php
setCookie('haveCookies',1);
Header('Location: http://site/main.php');
?
[main.php]
?php
if (empty($HTTP_COOKIE_VARS['haveCookies'])) {
return include error.php;
}
// the rest of php code goes here.
?
And BTW of globals off, ppl complain it's a lot to type (yap, one of
the virtues of a programmer, laziness), but hey you can assign those
long-named arrays to something simple, so if you have to work a lot
with, say, GET vars, just say $GV = $HTTP_GET_VARS; and go ahead w/ $GV.

Re: [PHP] Must Have Cookies. PHP/JavaScript
With a good start from the folks on this list and a little JavaScript
digging, I found an excellent solution to my problem that I thought I'd share:
Problem: Want to set a cookie then test for it on the same page. I don't
want to to do page redirection to ensure optimal search engine friendliness.
Solution: Set the cookie in PHP then test for the cookie with JavaScript.
Code example below:
?
if (! $MySession)
{
$SessionID = 2001 A Space Odyssey;
setCookie('MySession',$SessionID,time()+6048000,/,,0);
}
?
h t m l !--html tag done that way to ensure non-HTML appearance in e-mail
head
titleTest Page/title
SCRIPT LANGUAGE=JavaScript
cookie_name = MySession;
var Session;
function getSession()
{
if(document.cookie)
{
index = document.cookie.indexOf(cookie_name);
if (index != -1)
{
namestart = (document.cookie.indexOf(=, index) + 1);
nameend = document.cookie.indexOf(;, index);
if (nameend == -1)
{
nameend = document.cookie.length;
}
Session = document.cookie.substring(namestart, nameend);
return Session;
}
}
}
Session=getSession();
if (!Session)
{
CookieMessage = Cookies are not enabled. You can browse the site, but
will need to enable them to be able make a purchase.
}
else
{
CookieMessage =
}
/SCRIPT
/head
body
SCRIPT LANGUAGE=javascript
document.write(CookieMessage);
/SCRIPT
blah, blah, blah, the rest of the web page...
Enjoy,
