Payment Modules in Prestashop
Payment process in Prestashop is all about security and effectiveness. This is what makes it so
special. Information on delivery addresses and bank cards should be protected to prevent fraud –
and payment modules act like security guards in this case. Numbers, calculations and orders are
payment modules’ business as well. So how does it work? Let’s find out.
Class
/classes/PaymentModule.php
As you know, all modules are inherited from the class Module, except for the payment modules.
They are inherited from the abstract class PаymentMоdule, which in turn is inherited from the class
Modules (inherits the installation, removal, encapsulates module properties etc).
The class PаymentMоdule possesses configuration methods of certain current payment module
properties, for example: the permitted currency, the format of addresses and the list of the countries
for which this payment module can be applied.
The payment module can have one of two currency settings:
1. Checkbox – the module has the ability to work with multiple currencies;
2. Radio – the payment is available in one currency only (applicable for the modules, designed
for specific countries).
The method install of the class PаymentMоdule:
public function install()
{
if (!parent::install())
return false;
// Insert currencies availability
if ($this->currencies_mode == 'checkbox')
{
if (!$this->addCheckboxCurrencyRestrictionsForModule())
return false;
}
elseif ($this->currencies_mode == 'radio')
{
if (!$this->addRadioCurrencyRestrictionsForModule())
return false;
}
else
Tools::displayError('No currency mode for payment module');
