curreX is an AJAX powered Currency Conversion widget for WordPress sidebars.
As of version 0.7, it does. One should place a call to the function
show_currex( default_from, default_to, decimal_places, (optional) type, (optional) title ) in an appropriate place in the file sidebar.php for the non widget enabled theme.
The default_from and default_to here are 3 character shortened codes for the source and destination currencies. These 3 character codes can be found in the dropdown currency selection boxes of curreX, stated beside each currency.
decimal_places is an integer which denotes the precision (number of digits to display after the decimal point) of the conversion result.
title specifies the title to display embedded in the Flash widget. This parameter is optional too and if omitted, no title will be displayed in the widget. This parameter is directly related the the type of the widget, and if flash isn't the chosen type has no effect on the display anywhere. This feature is meant to act as a replacement for the default title field of a WordPress widget. I don't recommend using both together - as it'll be pointless and redundant.
A typical call to this function with source currency as US Dollars, destination currency as Thai Baht and precision set to 2 decimal places looks like,
<? show_currex( "USD", "THB", 2, 'flash', 'Currency Exchange' ); ?>
NOTE: Any version prior to 0.7 works only with widget enabled themes.
