Changing the sub-total wording depending on tax

[Ryk]

At present, I have the sub-total text say "Sub-total (including VAT @17.5%)"; the client has now expanded his options so that tax is sometimes NOT applied.

What I want to do is to change that sub-total text depending on whether tax is "on" or "off".

It seems to me that the logical place to do it is to insert a conditional statement in the function ot_subtotal in includes/modules/order_total/ot_subtotal.php to change the value of MODULE_ORDER_TOTAL_SUBTOTAL_TITLE so my question is - what is the variable for tax on/off?

What is the criteria for tax being "sometimes NOT applied" ?

Shipping destination by country

I gather your client is using "tax included in prices" via the admin switch.
Thus, prices always show with tax already included.

But, if the buyer's country matches a certain zone the "tax included" amount is zero because tax is not relevant.
And you're only wanting to change the display text if that tax amount is zero ?

Yep, that's it.

/includes/modules/order_total/ot_subtotal.php
line 38 says this:

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

change it to this:

      $this->output[] = array('title' => $this->title . ($order->info['tax'] == 0 ? '' : TEXT_TAX_INCLUDED_MESSAGE) . ':',

and add a language define to your extra-definitions folder saying this:

define('TEXT_TAX_INCLUDED_MESSAGE', '(including VAT @17.5%)');

And use the default name for the subtotal text (ie: "Subtotal").

Excellent - many thanks.
