code for adding Tax to Total in cart

[nrkar]

I would be grateful to someone who can help me with the coding for Cart.php file attached herewith.

I need to add Tax @7.75% to the SubTotal and the Grand total should appear just below the SubTotal.

 

Total :........

Tax:...........

Total Including Tax:.............

 

Thanks in advance...

It's 3:15 AM in the morning here, I honestly was going to help you further than give you the formula, but after seeing 1,500 lines of code, i couldn't skim it without passing out.

 

 

 

 

Formula for getting the tax: price*tax/100

$price_of_item = 50; 
$tax_rate = 7.75;
$total_tax = $price_of_item*$tax_rate/100;

echo '$$total_tax';

 

if you go search through cart.php after you find the "$price" variable in that script, you can add $tax variable.

I started you off on 1, I found the 1st price variable around lines 70 and down. i added a noted "TAX EDIT" i'm sure you can work from there, but If nothings figured out by tomorrow, i shall help you. Just really tired 

 

if($option_settings && is_array($option_settings)){
					// now we work out what values to add to the shopping cart session array.
					// we want the name of the product
					$product_name = $product_settings['name'];
					// we want it's price, the price of the option that the user selected:
					$price = $option_settings['price'];

					//TAX EDIT - you want the tax, well here it is.
					$tax = $option_settings['tax'];

					// we see if there is a name of the option that the user selected.
					if(isset($option_settings['name']) && $option_settings['name'] && $option_settings['name'] != $product_name){
						$product_name .= ' - ' . $option_settings['name'];
					}
					// and work out the quantity ordered, with a defualt of 1.
					$quantity = max(1, ((int)$_REQUEST['quantity']) ? (int)$_REQUEST['quantity'] : 1 ); 
					$product_uri = (isset($_REQUEST['url']))?$_REQUEST['url']:'';
					$new_product = array(
						// values that are showed to the user in checkout:
						"name"=>$product_name,
						"price"=>$price,
						"tax"=>$tax,
						"quantity"=>$quantity,
						"product_uri"=>$product_uri,
						"product_option"=>$product_option,
						"product_settings"=>$product_settings,
					);
