Add shipping charge based on state?

My client wants to add a $3 charge if she's delivering to a state west of Mississippi. Would I have to use a custom calculation for that? Can you give me an example?

Thanks - Joe

eCart stores the shipping state selected in a session called "eCartCheckoutForm_shipping_state_province"

you would need to hand code an array of all the states to the west of the mississippi:

$toTheWest = array();

$toTheWest[] = "CA";

$toTheWest[] = "WA";

$toTheWest[] = "UT";

$toTheWest[] = "TX";



etc...

then set a session if the selected shipping state is in the $toTheWest array:

$_SESSION['toTheWest'] = 0;

if(in_array($_SESSION['eCartCheckoutForm_shipping_state_province'], $toTheWest)) $_SESSION['toTheWest'] = 1;

in eCart create a new shipping rule as:
Based on Session Variable value:
if the session variable "toTheWest is "=" a value of "1"

Flat rate charge of "3"

Thanks, Jason - I'll give that a shot and let you know how it goes.

Jason - is the placement of the $toTheWest array creation and the session setting critical? I was going to put it on the checkout page before the WA redirect. Would that work?

Thanks - Joe

The code to create the array needs to be on the confirm page, after the code that sets the eCartCheckoutForm_shipping_state_province session variable
