losing session variables ... help

[tanaka99]

I have a secured area on my website, and I register some variables including a code that determines a level of access.

I'm building a shopping cart, and when I get to the page to view the cart contents I'm losing my session variables ...

Is there something in this function that's stripping them? I assume it's the session_start(), but if I remove it, I get the same results ... please help. Here's the function that I believe is to blame:

	function GetCartId()
	{
		// This function will generate an encrypted string and
		// will set it as a cookie using set_cookie. This will
		// also be used as the cookieId field in the cart table

	if(isset($_COOKIE["cartId"]))
	{
		return $_COOKIE["cartId"];
	}
	else
	{
		// There is no cookie set. We will set the cookie
		// and return the value of the users session ID

		session_start();
		setcookie("cartId", session_id(), time() + ((3600 * 24) * 1));
		return session_id();
	}
}

?>

umm i recall sumtin abt if u call session_start() from inside a functions the variables are not set globally. you will have to use the global keyword.

and jus to b clear, u need to call session_start() on every page dat u need to access the Session vars.

This not exactly in regards to this thread but, I want to thank you Rohit for an insight in stating that "... need to call session_start() on every page..." -- it has helped me a lot on my project (I'm a newbie to PHP).

Thank You.
