setcookie is not changing value

phorbidden

here is the code I am using

	function detectiPhone($query){
		$container = $_SERVER['HTTP_USER_AGENT'];
		//print_r($container); //this prints out the user agent array. uncomment to see it shown on page.
		$useragents = array ("iPhone","iPod");
		if ($_GET['iphonechoice'] == 'no') {setcookie("iphoneTemplate", "noway", time() + 1814400);}
		$this->iphone = false;
		foreach ( $useragents as $useragent ) {
			if (eregi($useragent,$container) && $_COOKIE['iphoneTemplate'] != 'noway') {
				$this->iphone = true;
				setcookie("iphoneTemplate", "yes", time() + 1814400);
			}
			if (eregi($useragent,$container) && $_COOKIE['iphoneTemplate'] == 'yes') {
				$this->iphone = true;
			}
		}

basically it runs and sets the cookie to yes, but even when it enters the iphonechoice if statement it will not change the cookie to 'noway'. All of this is being done before the headers are printed... I just don't see why it sets it to 'yes' enters the if statement and never changes to 'noway'

I tracked it down with a bunch of echos and this is where I am stuck. Please let me know.

there is a missing }, I forgot to cut and paste it cause there is a bunch of commented code before it, and that is not my issue 😉

setcookie() does not set a value in $COOKIE. It adds the desired cookie to the HTTP headers queued up to be sent to the browser. $COOKIE gets populated at script start based on the cookies (if any) the browser sent as part of its HTTP headers requesting a new page. If you need to add/change a $_COOKIE value in your script, you will have to set it explicitly.

I wouldn't go quite that far. 😉 Especially since a lot of people seem to make that same mistake.

ok but now if I need to change the value it seems that using

$_COOKIE['iphoneTemplate'] = 'noway';

is not working... or at least it works but then changes the value back, it is not sticking.

I don't think cookies work like sessions.
Try using setcookie() to change the value.

Well I figure if you set a value in a cookie you would be able to change it. Like changing templates... how else do you all store thevalue... probably in sql... but I am trying to mod a plugin for wordpress... without having to touch the DB.

Yes, by setting another cookie with the same name (and other relevant parameters) but different value.

phorbidden

right by using setcookie

that doesn't seem to work either. I will mess with it some more and let you know what I find.

thank you all for the constant updates!
