Hi,
Below is a function I have written to update the Cookie of a Shopping Cart.
To me, the logic seems fine But how are Cookies updated from stored Arrays like this ?
This is the original cookie ...
Array ( [ECAcart] => Array ( [coppercasserole] => Array ( [qty] => 1 [desc] =>
Copper Casserole [price] => 2199 ) [steelcasserole] => Array ( [qty] => 1 [desc]
=> Steel Casserole [price] => 2099 ) [steelfrying] => Array ( [qty] => 1 [desc]
=> Steel Frying [price] => 899 ) ) )
The cookie after updating with 1item that already exists in the Cart ...
Array ( [coppercasserole] => Array ( [coppercasserole] => Array ( [qty] => 1
[desc] => Copper Casserole [price] => 2199 ) [steelcasserole] => Array ( [qty]
=> 1 [desc] => Steel Casserole [price] => 2099 ) [steelfrying] => Array ( [qty]
=> 1 [desc] => Steel Frying [price] => 899 ) ) [steelcasserole] => Array ( [qty]
=> 1 [desc] => Steel Casserole [price] => 2099 ) [steelfrying] => Array ( [qty]
=> 1 [desc] => Steel Frying [price] => 899 ) )
