false if not

boolean configfile_writeable( void )

returns true if the configuration file for that payment module is writeable,

false if not

boolean configfile_readable( void )

returns true if the configuration file for that payment module is readable,

false if not

void write_configuration( Array )

Stores all configuration values for this payment module in the configuration file.

boolean process_payment(String $order_number, Float $order_total, Array &$d)

This is the main function for all payment modules that use direct connections to a payment gateway

(like authorize.net or eWay XML). This is the place, where the payment details are validated and

captured on success.

Returns true on sucess, false on failure.

float get_payment_rate(Float $subtotal)

This is the function to calculate the fee / discount for this special payment module (so you can cal-

culate a fee, depending on the order total amount).

Note

IF you are about to change configuration variables: do this in both functions: show_configuration and

write_configuration!

5.1.4. Installing a Payment Module

Since there's no real installer for payment modules, you must copy the two files ps_mynewpayment.php

and ps_mynewpayment.cfg.php into the directory

/administrator/components/com_virtuemart/classes/payment/

first.

After you have done that, you can add a new payment method ("Store" => "Add Payment Method"). It's impor-

tant to fill in the correct name for Payment Class Name (in this case: ps_mynewpayment) - here's the reason

why you must give the class file the same name as the class inside the file: the Shop now tries to include a file

called "ps_mynewpayment.php" on Saving the payment method.

When you now re-open the newly created payment method, you have access to the configuration form.

5.2. Shipping Modules

5.2.1. The Basics

Shipping modules are located in the directory

/administrator/components/com_virtuemart/classes/shipping/

and have three files: the class file, the information file and the configuration file.

Example: Module "myShipping"
