Question

I have a class named MyCart.

Class MyCartClass
{
var $MyCart;  

function getCart(){
  return $this->MyCart;
}

function addItem($item){

    if ($this->MyCart){
        $this->MyCart .= ','.$item;
    } 
    else{
        $this->MyCart = $item;
    }

}

};

$globalCart = new MyCartClass; // create an instance of the class

The variable "$MyCart" is a string containing all the items in the cart, separated with a comma.

Now, I save this class to a file named "cart.php" and I include it in another file.

HOWEVER, every time I call the function "addItem", the if statement goes to the else branch, which means that the "$MyCart" variable does not contain the current state of the cart.

Do i need to store the state of my cart into a “session” variable?
Cause this way it will be accessible from all files for sure..

I would appreciate any kind of help!

Thanks.

Answer 1

If you mean saving it between request then yes you need to put it in $_SESSION.

Otherwise within one request you can use your $globalCart and not lose the contents of your $myCart var.
