Tax Value (URGENT PLEASE)

Tax Value (URGENT PLEASE)

The cart has to calculate the tax value, but since it is already included on the price item, I need the cart to state the figures like this:

Let’s imagine an article that costs 79,92 euros (that is the amount appearing on the catalogue), then:

The catalogue shows: 79,92 and the cart must show this:

Sub-total: 68,90
Tax base: 68,90
Tax amount: 11,02
Total including tax: 79,92

How can I make my cart to work like that?

you would need to modify the total price calculation to deduct the tax amount from the sub total, and create a tax calculation to determine the the total tax amount.

You could then create a tax charge to use the tax calculation and display the tax amount as a line item in the cart.


I'm not sure of your exact tax amount, but the totalprice calculation would be:
([Price] - ([Price] * <tax percentage>)) * [Quantity]



Create another calculation called tax:
[Price] - ([Price] * <tax percentage>)

Tax calculation

Hi Jason Byrnes,

Thank you for your reply.

Please note that the tax percentage is passed through a session variable called TaxRate, since it is taken according to the state the customer states on his form.

In that case, what would be the formula of the total price calculation?, since I want the tax is deducted from the total price in the cart.

You wrote this formula:

([Price] - ([Price] * <tax percentage>)) * [Quantity]

Where the <tax percentage> is there should be the session variable called TaxRate that I have created? How shall I write it for it to work?

Shall I use this on the formula < >?

Please tell me the exact formula I have to write on the calculation.

Thank you for your kind help.

Regards,

Israel

if the name of the session variable is "tax" the calculation would be:
([Price] - ([Price] * $_SESSION['tax'])) * [Quantity]

Now I have one problem. I have generated 3 pages: cart.php, checkout.php and confirm.php. In order to get all values correctly in the confirm.php, I have to refresh the page manually. Otherwise, the calculation of the Tax, shipping etc is not done properly. How can I manage this?

Just after the body tag on the confirm page add the following code:

php:
<?php

$<cart Name>->GetContent();
?>





where "<cart Name>" is the name of your eCart object.
