在下订单前请求密码确认 - Magento

Question

在我们的Magento CE 1.7商店，我们允许“贸易”客户组中的客户下单并支付采购订单。

我们需要实施一个额外的安全层 - 当客户到达结账流程的订单审核步骤时，就在通过采购订单付款方式下订单之前，需要提示他们请求他们帐户登录密码（即使他们已登录）。他们需要正确输入他们的账户密码才能下订单。

这是一个相当困难的前景，我知道 - 有谁知道这是相对可能的，或任何现有的模块，提供这种功能？

在此先感谢！

你也许可以做到这一点使用事件/观察者，但我会做到这一点的方法是使用自定义的付款方式，基本上重复定单

见/应用/代码/核心/法师/支付/型号/法/Purchaseorder.php

class Mage_Payment_Model_Method_Purchaseorder extends Mage_Payment_Model_Method_Abstract 
{ 

    ..... 


    /** 
    * Validate payment method information object 
    * 
    * @return Mage_Payment_Model_Abstract 
    */ 
    public function validate() 
    { 
     $paymentInfo = $this->getInfoInstance(); 

     validate customer password there 

     if($paymentInfo->getOrder()->getCustomerId()){ 

      //see login() in /app/code/core/Mage/Customer/Model/Session.php 
      $customer = Mage::getModel('customer/customer') 
       ->setWebsiteId(Mage::app()->getStore()->getWebsiteId()); 
      //May need to change to the order store id and not Mage::app()->getStore()->getWebsiteId() 

      //get password enter on PO screen 
      $password = $paymentInfo->getPassword() 

      if ($customer->authenticate($paymentInfo->getOrder()->getCustomerEmail(), $password)) { 
       return true; 
      } 
      return false; 
     } 
     else{ 
      //customer not login 
      return false; 
     } 

     /** 
      * to validate payment method is allowed for billing country or not 
      */ 
     if ($paymentInfo instanceof Mage_Sales_Model_Order_Payment) { 
      $billingCountry = $paymentInfo->getOrder()->getBillingAddress()->getCountryId(); 
     } else { 
      $billingCountry = $paymentInfo->getQuote()->getBillingAddress()->getCountryId(); 
     } 
     if (!$this->canUseForCountry($billingCountry)) { 
      Mage::throwException(Mage::helper('payment')->__('Selected payment type is not allowed for billing country.')); 
     } 
     return $this; 
    } 

    /** 
    * Assign data to info model instance 
    * 
    * @param mixed $data 
    * @return Mage_Payment_Model_Method_Purchaseorder 
    */ 
    public function assignData($data) 
    { 
     if (!($data instanceof Varien_Object)) { 
      $data = new Varien_Object($data); 
     } 

     $this->getInfoInstance()->setPoNumber($data->getPoNumber()); 
     $this->getInfoInstance()->setPassword($data->getPassword()); 
     return $this; 
    } 


}
