COOKIES in PHP

[happyturtle]

I am using cookies on my website and they will not travel when you click on a link.

 

I am using /folder/folder1/folder2/.

 

Can anyone help me?

 

	if($_COOKIE['per'] == "" AND $_GET['per'] == "") {
	$limit = 24;
} else {
	setcookie("per", $_GET['per'], time()+60*60*24*100, "/");
	$limit = $_COOKIE['per'];
}
if($_GET['per'] != "") {
	header("Location: /");	
}

 

Thanks.

If you can provide more code, it might help tracking it down.  However, I see one potential problem with your posted code:

if($_COOKIE['per'] == "" AND $_GET['per'] == "") {
	$limit = 24;
} else {
	setcookie("per", $_GET['per'], time()+60*60*24*100, "/");
	$limit = $_COOKIE['per'];
}

You're saying if "per" is empty in the cookie and the URL, then you set the limit to 24.  Your else sets the "per" to the value of "per" in the URL.  What if this isn't set?  You could have the cookie filled and URL parameter empty, which would reset your cookie value to an empty value.

 

You can try this

if(empty($_COOKIE['per']))
{
if (empty($_GET['per']))
	setcookie('per', 24, time()+60*60*24*100, '/');
else
	setcookie('per', $_GET['per'], time()+60*60*24*100, '/');
}
$limit = $_COOKIE['per'];

 

You'll also want to verify the values of 'per.'  You can find out more here:
