Order tables in prestashop when should be it created? - paypal

Question

When should actually an order must be created in PrestaShop, We integrated a local payment module which will redirect to there page and after entering card details and validating the payment it returns back , and it creates an order at that time.
My problem is that if the payment is declined , (or if I close the browser when the payment is processing in the payment page ) order is not created in the ps_order table but cart is created and if I query the bank with another WEB service the payment response is success for that cart_id and id_order is 0,
but I dont have an order or entry in ps_order table created in my ps_order table .How to cater this scenario?
Is it correct to create the order (insert into the order table )before payment processing and put current_state field as 3 status 3 means Processing in progress and change the current_state field if the payment is success or not.
select * from ps_orders
this is how the payemnt module does
if($reponseParameters[8]=='00000'){
// Update the Respose to the ps_networkonline_payment
$sql_response = " UPDATE `"._DB_PREFIX_."networkonline_payment` SET response = '".$text."' , `status` = '".$reponseParameters[4]."', error_code = '".$reponseParameters[8]."' WHERE order_id = '".$cart->id."' ";
Db::getInstance()->execute($sql_response);
// Create Order In prestashop pass the values to order-confrimation class
$total = (float)$cart->getOrderTotal(true, Cart::BOTH);
$this->module->validateOrder($cart->id, Configuration::get('PS_OS_PAYMENT'), $total, $this->module->displayName, 'Transaction Reference: ' . $reponseParameters[5], array(), (int)$currency->id, false, $customer->secure_key);
// Update the ps_order_payment table to make the PrestaShop Payment success
$q_orders = 'SELECT `reference` FROM ' . _DB_PREFIX_ . 'orders WHERE `id_cart` = ' . (int) $cart->id;
if ($r_orders = Db::getInstance()->getRow($q_orders)){
Db::getInstance()->execute('UPDATE `' . _DB_PREFIX_ . 'order_payment` SET `transaction_id` = \'' . pSQL($reponseParameters[5]) . '\' , `card_brand` = \'' . pSQL($reponseParameters[7]) . '\' WHERE `order_reference` = \'' . pSQL($r_orders['reference']) . '\'');
}
Tools::redirect('index.php?controller=order-confirmation&id_cart='.$cart->id.'&id_module='.$this->module->id.'&id_order='.$this->module->currentOrder.'&key='.$customer->secure_key);
return;
}else{
$this->error = $reponseParameters[9];//$this->module->getErrorMessage($object->error_code);
$total = (float)$cart->getOrderTotal(true, Cart::BOTH);
$this->module->validateOrder($cart->id, Configuration::get('PS_OS_ERROR'), $total, $this->module->displayName, $this->error, array(), (int)$currency->id, false, $customer->secure_key);
}
}else{
//fail
$this->error = $reponseParameters[9];//$this->module->getErrorMessage($object->error_code);
$total = (float)$cart->getOrderTotal(true, Cart::BOTH);
$this->module->validateOrder($cart->id, Configuration::get('PS_OS_ERROR'), $total, $this->module->displayName, $this->error, array(), (int)$currency->id, false, $customer->secure_key);
}
}

What payments modules usually have is a way for the bank to query your website when your customers are redirected to their platform, this way the order is created on your side no matter what happens on their side (leaving you with a freshly created order with a state like "pending payment").
Then the order is updated on the customer's return to your website, by a call from the bank (be it with a status "blocked", "cancelled", or "payment accepted").
