[RESOLVED] sigh a cookie problem

VisionsOfCody

I've got cookie problems on localhost php/apache, winXP, Firefox

I've been using this page to set and test a cookie and it works fine (the setcookie was from HERE

<?php if($_GET['action']=="set"){setcookie("clientid", "1", false, "/", false);
	header("Location: TEST-cookie.php");
}
if($_GET['action']=="delete"){setCookie("clientid");
	header("Location: TEST-cookie.php");
} 
?>

<title>cookie test</title>
</head>

<body>
<a href="TEST-cookie.php?action=set">setting cookie</a><br />
<a href="TEST-cookie.php?action=delete">deleting cookie</a><br /><br />
<?php
  echo "cookie = ".$HTTP_COOKIE_VARS["clientid"];
?>
</body>
</html>

that works fine but when i try to test it with

if(isset($HTTP_COOKIE_VARS["clientid"])){

in a different page it reckons the cookie hasn't been set

is there some obvious thing I'm missing here ?

thanks

<?php
if(isset($_GET) && !empty($_GET))
{
	if(@$_GET['action'] == 'set')
		setcookie('clientid', '1', false, '/', false);
	elseif(@$_GET['action'] == 'delete')
		setcookie('clientid', '', false, '/', false);

header('Location: TEST-cookie.php');
}

?>

<a href="TEST-cookie.php?action=delete">deleting cookie</a><br /><br />
<?php
if(isset($_COOKIE) && !empty($_COOKIE))
	echo '
<strong>$HTTP_COOKIE_VARS[\'clientid\']:</strong> ' . @$HTTP_COOKIE_VARS['clientid'] . '<br />
<strong>$_COOKIE[\'clientid\']:</strong> ' . @$_COOKIE['clientid'] . '<br />';
?>
</body>
</html>

That works for me. Try clearing out all your cookies for that specific session in that tab, then try again. I had to do that, but after that it works flawlessly.

You'll notice a few differences:
1.) I moved the header() function out of the conditionals to be one call
2.) I only act upon the $_GET value if it's set and not empty (reduces warnings)
3.) I provide an empty cookie (content, time, and domain) to "delete" or reset the cookie.
