cart total incl. tax, but want it excl. tax

I want the cart to display the total price excluding tax, in stead of incl. tax.

It's now like:

Code: Select all

<div class="gkTotal"> <?php echo str_replace(JText::_('COM_VIRTUEMART_CART_TOTAL'), '', $data->billTotal); ?> </div>

I tried for example:

Code: Select all

<div class="gkTotal">
<?php
$taxCoEf = 1.21;
$totalInTax = $data->billTotal;
$totalExTax = $totalInTax / $taxCoEf;
echo str_replace(JText::_('COM_VIRTUEMART_CART_TOTAL'), '', $totalExTax);
?>
</div>

I'm pretty noob with php, but do my best. This gives a '0' as result. What can I do else?

As patient as I am, I figured it out myself.
I needed to add an extra line to /components/com_virtuemart/helpers/cart.php
After line 1675

Code: Select all

// ex tax is what we want as well
$data->billTotal_net = $currencyDisplay->priceDisplay( $this->cartPrices['discountedPriceWithoutTax'] );

I changed the code on line 98 in /templates/gk_instyle/html/mod_virtuemart_cart/default.php to:

Code: Select all

<div class="gkTotal"> <?php echo str_replace(JText::_('COM_VIRTUEMART_CART_TOTAL'), '', $data->billTotal_net); ?> </div>

That works like a charm. See: http://www.vdmkantoormeubelen.nl/
