check session array

[robert_gsfame]

I create session for my shopping cart n wish to check whether certain product has been added into cart.

I use in_array but not working...

 

session_start();

$productname=$_GET['productname'];

if(in_array($productname,$_SESSION['cart'])){

echo "Product has been added";}else{

echo "Not yet added";}

 

I always get the second answer although i have created the session for the product...

 

thx for any helps

What does $_SESSION['cart'] look like? Maybe you need to use array_key_exists or simply isset.

I just put product id inside $_SESSION['cart'][x]

If you only put the product id in the cart array then you can't use the product name in your in_array() call, which is what you have done in post 1. You'll need to use the product id in the in_array() call, not the product name because from what you say, that doesn't get stored.

$_SESSION['basket'][$x] and when $x already exists, then $x++

 

I've checked everything and nothing wrong with the array, except using in_array to check whether the record exists

 

I can do with loop, but i don't think it's efficient enough

Sorry guys!! I forgot that i've encoded the product id...

 

Thx for all helps!
