Order Total Order changed but need to change 'Sub-Total' calculations

[mylittlereddress]

I am trying to change the the order total so that it gives

 

Subtotal:

Shipping:

Subtotal Excl VAT:

VAT:

Total Incl VAT:

 

At the moment the "Subtotal Excl VAT" does not include the Shipping, and the "VAT" is not being calculated to include VAT on "Shipping".

 

I have been looking at catalog/includes/modules/order_total folder to change how the various totals are calculated.

 

Am I looking at the correct files? Or should I be looking elsewhere please?

 

Many thanks in advance

Is there anyone who knows where the code to calculate totals is please?

If anyone else has this problem, I have finally worked it out.

 

To give the Sub-Total ex VAT but including the shipping,

 

catalog/includes/modules/order_total/ot_subtotal_ex.php

 

Find:

 

if (DISPLAY_PRICE_WITH_TAX == 'true')

{

$this->output[] = array('title' => $this->title . ':',

'text' => $currencies->format($order->info['subtotal']-$order->info['tax'], true, $order->info['currency'], $order->info['currency_value']),

'value' => $order->info['subtotal']);

 

}

else

{

$this->output[] = array('title' => $this->title . ':',

'text' => $currencies->format($order->info['subtotal'], true, $order->info['currency'], $order->info['currency_value']),

'value' => $order->info['subtotal']);

 

}

 

Change to:

if (DISPLAY_PRICE_WITH_TAX == 'true')

{

// Changed to added shipping cost to the subtotal - added +$order->info['shipping_cost'] into both lines below

$this->output[] = array('title' => $this->title . ':',

'text' => $currencies->format($order->info['subtotal']-$order->info['tax']+$order->info['shipping_cost'], true, $order->info['currency'], $order->info['currency_value']),

'value' => $order->info['subtotal']+$order->info['shipping_cost']);

 

}

else

{

// Changed to added shipping cost to the subtotal - added +$order->info['shipping_cost'] into both lines below

$this->output[] = array('title' => $this->title . ':',

'text' => $currencies->format($order->info['subtotal']+$order->info['shipping_cost'], true, $order->info['currency'], $order->info['currency_value']),

'value' => $order->info['subtotal']+$order->info['shipping_cost']);

 

}

 

Basically you are adding +$order->info['shipping_cost'] to anywhere there is $order->info['subtotal']

 

This may or may not be the correct way of doing it, but it did work for me.
