$_SESSION question.

[devianleong]

Hi, now I've a function which is add product to cart:

    function addtocart($pid,$q,$attribute){
        if($pid<1 or $q<1) return;

        if(is_array($_SESSION['cart'])){

            $max=count($_SESSION['cart']);
            $_SESSION['cart'][$max]['productid']=$pid;
            $_SESSION['cart'][$max]['qty']=$q;
            $_SESSION['cart'][$max]['attribute']=$attribute;
        }
        else{
            $_SESSION['cart']=array();
            $_SESSION['cart'][0]['productid']=$pid;
            $_SESSION['cart'][0]['qty']=$q;
            $_SESSION['cart'][0]['attribute']=$attribute;
        }
    }

And now my remove product function is :

$id is generate from for loop in cart page which is same value with $i below

    function remove_product($id){
        $id=intval($id);
        $max=count($_SESSION['cart']);
        for($i=0;$i<$max;$i++){

            (This part how to determine $_SESSION['cart'][$i] that match with $id)?

                unset($_SESSION['cart'][$i]);
                break;
            }
            if($_SESSION['cart'] == ''){
            unset($_SESSION['cart']);   
            }
        }
        $_SESSION['cart']=array_values($_SESSION['cart']);
    }

my previous code is :

if($pid==$_SESSION['cart'][$i]['productid']){
unset($_SESSION['cart'][$i]);
break;

but now I don't want to determine productid , I want to determine the number $i that pass from my cart page and remove the item. Any solution?

Even before we start assisting you. You have to be very honest with us. Where did you get this code? Are you using a platform like Magento or Prestoshop? If so you are trying to modify the file? If you did created this code, you should know there is a by pass and so far the code you provided doesn't show any sign of it. You need to post a code related to that
