Making Sales/State tax option click proof

[xccelerant]

I was wondering if it was possible to move the sales tax field to the checkout page, instead of having the user decide. This way when the user inputs their billing info, the state field is a drop down box and when they click on the state that has sales tax, there is no way to bypass it. Right now with the NopCart example site you can select Other States: even if you live in Arizona and not be charged sales tax. Has anyone tried modifying this??

I tried modifying an existing script and adding this to the header of the check out page.

<SCRIPT>
function calculate() {
if (document.CheckoutCart.b_state.options[document.calcform.State.selectedIndex].value == 'NY') {
// ADJUST YOUR TAX RATES ON THE LINE BELOW --------------------------------------------
document.CheckoutCart.tax.value = dp((document.CheckoutCart.subtotal.value) * 0.0825)
document.CheckoutCart.total.value = dp((document.CheckoutCart.subtotal.value) * 1.0825)
} else {
document.CheckoutCart.tax.value = dp((document.CheckoutCart.subtotal.value) * 0.000)
document.CheckoutCart.total.value = dp((document.CheckoutCart.subtotal.value) * 1.000)
}
</SCRIPT>

This is the dropdown to the check out page State field.

Sounds like a good idea.

The managecart page would list the State Sales Tax for the State where the store is located.

The only change I would make is check to see if the b_state == s_state -- it is the state you are shipping to that determines the tax, not the where the customer gets the bill...

Hello Randy,

Thanks for replying. I'm surprised this hasn't already been done since it seems to be the only weak link with this cart. I just started with NOPcart so I am still figuring it out and not up on Javascript. Wheres the best spot to call the function. Right now I was thinking of doing it on the checkout page, but since the tax is already figured on the managecart can I call an existing function and compute it on the checkout page, or since it is already computed, then just have it added and recomputed when the state is selected?

You are right on what determines the tax. Thanks.
