Hi,
What you can do is edit the file administrator/components/com_hikashop/classes/cart.php and add after the code:
if(!empty($shipping_id)){
$cart->shipping = $app->getUserState( HIKASHOP_COMPONENT.'.shipping_data');
if(!empty($cart->shipping)){
$currencyClass = hikashop::get('class.currency');
$shipping =& $cart->shipping;
$shippings = array(&$shipping);
$currencyClass->processShippings($shippings);
//calculate total price with shipping
$currencyClass->addShipping($cart->shipping,$cart->full_total);
$cart->full_total=&$cart->shipping->total;
}
}
the code:
if(bccomp($cart->full_total->prices[0]->price_value_with_tax,0,5)<=0){
$cart->full_total->prices[0]->price_value_with_tax = 0;
$cart->full_total->prices[0]->price_value = 0;
}
Let us know if that works and we will included it in next version of HikaShop.
