$_SESSION and stored info

Recommended Posts

Hi,
I’m using PHP OOP and created an instance of the class and stored the content inside a $_SESSION['cart']

 

1...   I can validate, if “prid” exists in the session with this …. 

        How would i check for "prid" and "prflavour" Mango ? 

   if (isset($_SESSION['cart'][12]))

2...    I need to update the quantity when both conditions "prid" and "prflavour" are met.

 

how do i change this $_SESSION['cart'][$_GET['prid']]-> to work with prid and prflavour

$_SESSION['cart'][$_GET['prid']]->updateQuantity(123)

sample of the $_SESSION['cart']

Array
(
    [13] => Item Object
        (
            [prid:protected] => 13
            [prname:protected] => Meal
            [prflavour:protected] => Mango

            [prqty:protected] => 10
        )

    [12] => Item Object
        (
            [prid:protected] => 12
            [prname:protected] => Milk
            [prflavour:protected] =>
            [prqty:protected] => 123
         )

)

prid and prflavour (and the other two) are protected, which means you can't change them in your code like you're trying to do. You need to use methods in the class. For example,

1. Use a getFlavour() method to get the flavor and check that it is "Mango"

2. Use updateQuantity() just like how you have there

 

If your problem is finding out which object in the array is the Mango item then you need a loop like

foreach ($_SESSION['cart'] as $prid => $item) {
	if ($item->getFlavour() == "Mango") {
		$item->updateQuantity(123);
		break; // don't need to check the rest of the cart
	}
}
What would be nicer than this is if you had a sort of ItemCollection that could do much of this work for you. One class representing an entire cart. Then that class could handle the searching part, and you could call it with code like

$_SESSION['cart']->updateFlavourQuantity("Mango", 123);
