Module Class - Prestashop Override

// Add custom logic BEFORE parent execution PrestaShopLogger::addLog("Custom: Validating order for cart #$id_cart", 1, null, 'Cart', $id_cart);

While modifying a module's core files directly is a disaster waiting to happen (updates will erase your changes), provide a clean, upgrade-safe solution.

// Add custom logic AFTER parent execution if ($result) PrestaShopLogger::addLog("Order validation successful!", 1); prestashop override module class

return $result;

// Keep original module properties parent::__construct(); provide a clean

// Call the original method from the original module class // Note: The original class is automatically aliased as 'MyBankPaymentOriginal' by PrestaShop $result = parent::validateOrder($id_cart, $id_order_state, $amount_paid, $payment_method, $message, $extra_vars, $currency_special, $dont_touch_amount, $secure_key, $shop);

PrestaShop is a powerful e-commerce platform, but every merchant eventually hits a limitation: "I need to change how this module works." // Keep original module properties parent::__construct()

/override/modules/mybankpayment/ Inside that folder, create a file named after the original module’s main class, but with override in the name? No – the file must be named exactly like the original class, but placed in override.
