Simple session problem

[richblend]

Im making a shopping cart object, which holds the contents of the cart in a mutlidimensional, associative array. Im ok with sessions, but not too hot on objects, which is probably where the problem lies. heres the bit of the code im interested in...

function add_item($item){	
		//$item is associative array
		//$n= next slot in the array. when added to cart, register session data
		$n=count($this->contents);
		$this->contents[$n]['id']=$item['id'];
		$this->contents[$n]['name']=$item['name'];
		$this->contents[$n]['quantity']=$item['quantity'];
		$this->contents[$n]['price']=$item['price'];
		$this->contents[$n]['description']=$item['description'];
		$this->contents[$n]['total_price']=$item['total_price'];

	$session_data=$this->contents;
	session_register("session_data");

}

I thought that would register the contents array into the session, but when i try to access this array on the next page, after starting the session, its not there.

Oh, and there IS a call to session_start() before that code.. so thats not the problem...

thanks for any help....

Try
print_r($this->contents);
and see if there is any output

yeah, i did that. the array is populated perfectly, for some reason it just doesnt want to work with the sessions.

Did you try:

$_SESSION['session_data']=$this->contents;

🙂

actually, not yet, no... i think the book i learnt from must be a little old fashioned. i had no idea that you could put stuff in the session array that way (i dunno why, it stands to reason really).

i thought the only way you could do it was with session_register(), which seemed a bit odd, but thats what my book told me!

Ill give it a go and get back.

Cheers

$_SESSION is new, and session_register is depreciated. 🙂
