To display the $$ value anywhere, make sure that you have installed the reward points mod to display the points in the location of which you want to show the dollar value. Then:
Open auth.php and before ?> put:
Code:
// WCM - Pass the points payment rate to the template for $$ display
$payment_rate = func_query_first_cell("select value from points_config where name='payment_rate'");
$smarty->assign("wcmPaymentRate",$payment_rate);
In your template file:
Code:
{math x=$points.total y=$wcmPaymentRate equation="x / y" format="%.2f" assign="wcmPointsDollars"}
{include file="currency.tpl" value=$wcmPointsDollars}
Voila.
