Virtuemart PayPal API Bugs and Solutions
Problem
The introduction of new payment method "PayPal (new API)" is causing "Credit Card" payment option to appear for no reason.
Solution
To completely get rid of this problem, there are 3 files involved
- administrator/components/com_virtuemart/classes/ps_checkout.php -> method list_payment_methods()
- administrator/components/com_virtuemart/classes/ps_payment_method.php -> method list_payment_radio()
- components/com_virtuemart/themes/default/templates/checkout/get_payment_method_paypal_ex.tpl.php
administrator/components/com_virtuemart/classes/ps_checkout.php Line 826-834
Paypal (new API) are implemented separately from generic Virtuemart payment methods. So we need to prevent it from reloading again
function list_payment_methods( $payment_method_id=0 ) {
...
$db_nocc = new ps_DB;
$q = "SELECT * from #__{vm}_payment_method,#__{vm}_shopper_group WHERE ";
$q .= "#__{vm}_payment_method.shopper_group_id=#__{vm}_shopper_group.shopper_group_id ";
$q .= "AND (#__{vm}_payment_method.shopper_group_id='".$auth['shopper_group_id']."' ";
$q .= "OR #__{vm}_shopper_group.default='1') ";
$q .= "AND (enable_processor='B' OR enable_processor='N' OR (enable_processor='P' AND `payment_class`!='ps_paypal_api')) ";
$q .= "AND payment_enabled='Y' ";
$q .= "AND #__{vm}_payment_method.vendor_id='$ps_vendor_id' ";
$q .= " ORDER BY list_order";
...
}

If you only use one payment method "Paypal (new API)", you need that payment method to be selected by default.
