Adding a new currency in 2.3 version of osCommerce is now incredibly easy. Go to your admin area > localization > currencies;
On this page, you’ll likely see “US Dollars” and “Euro” installed. To install a new currency, click the [+ New Currency] button, and you’ll see a number of input boxes ready for the new currency to be inserted. Just like the older versions of osCommerce…
What is new is the dropdown list of “pre-installed, but not active” currencies;
Selecting one of these from the dropdown will populate the input boxes, as so (I chose New Zealand Dollars);
So all I now have to do is press the [save] button. And now my shop is also able to use NZD as one of it’s currencies.
Updating the new Currency
It’s important to note that evary time you add in one or more new currencies, you must also press the [update exchange rate] button, else you will find that you are making a good profit or a bad loss when people pay you in currencies other than your shops default!
Easy as 123.
