Sometimes its helpful to have a payment method ‘preselected’ for customers in the checkout area, so they avoid getting an error message if they miss that option. Or maybe you want to select a method for them as an example of what it looks like … plenty of reasons. This short article explains how to set a default payment method in oscommerce 2.2 and cre loaded 6.4.1a carts (which is slightly harder as cre is using runoverride files now to ‘steer things in a paypal direction.’)
Oscommerce 2.2 version
Backup the file: /catalog/checkout_payment.php and edit as follows:
Find:
1) {
echo tep_draw_radio_field('payment', $selection[$i]['id']);
} else {
echo tep_draw_hidden_field('payment', $selection[$i]['id']);
}
?>
Replace with:
1) {
if ($i == 0) {
$checked = true;
} else {
$checked = false;
}
echo tep_draw_radio_field('payment', $selection[$i]['id'], $checked);
} else {
echo tep_draw_hidden_field('payment', $selection[$i]['id']);
}
?>
Cre Loaded 6.4.1a
Backup the file: /catalog/includes/runoverride/ordercheckout/paypalxc_ordercheckout_paymentmodule.php
To get the selector bar highlighting the payment method row, modify as follows, replacing the payment method name in the ‘name of payment method’ bit:
If you’re not sure of the payment module names, go to Admin >> Modules >> Payment area, click on a module and read it’s name from the url in the address bar. Or just check in the /includes/modules/payment folder and drop the .php extension.
To get the radio button to default to the selected payment module, modify the following:
1 || $ec_enabled ) {
if ($i == 0) { // defaults to payment method with id=0 NOT related to sort order in admin
$checked = true;
} else {
$checked = false;
}
echo tep_draw_radio_field('payment', $selection[$i]['id'], $checked);
} else { ...
The key part in the code is the $i==0 which refers to the payment method id. This ISN’T related to the sort order of the payment modules in the Admin >> Modules >> Payment area, or some ‘name sort’ principle. Instead it just reflects the order of the modules in the database constant MODULE_PAYMENT_INSTALLED.
So if you take a look at the configuration table in your database and search for MODULE_PAYMENT_INSTALLED, your payment modules will be in a row there –
eg moneyorder.php,transfer.php,paypal.php
Here, moneyorder will have the id = 0 (so $i == 0 to be selected by default), transfer’s id = 1, paypal’s id = 2 … etc.
So by changing the $i == 0 in the code examples above to match your payment method id, you can easily set the default payment method at checkout.
