在Magento中添加一个自己的支付模块----第三部分

在前两部分解决了在后端配置自定义支付方式，在确认订单时显示提交方式；

• app/code/local/Envato/Custompaymentmethod/Helper/Data.php:这是帮助文件，用来提供实体方法；
• app/code/local/Envato/Custompaymentmethod/controllers/PaymentController.php:这是控制器文件，为支付网关页补充必要的执行文件；
• app/design/frontend/base/default/template/custompaymentmethod/redirect.phtml: 这是支付网关页面的模板文件；

app/code/local/Envato/Custompaymentmethod/Helper/Data.php

<?php

// app/code/local/Envato/Custompaymentmethod/Helper/Data.php

class Envato_Custompaymentmethod_Helper_Data extends Mage_Core_Helper_Abstract

{

  function getPaymentGatewayUrl()

  {

    return Mage::getUrl('custompaymentmethod/payment/gateway', array('_secure' => false));

  }

}

说明：在帮助文件中，定义一个方法来返回自定义支付方式的返回地址；

app/code/local/Envato/Custompaymentmethod/controllers/PaymentController.php

<?php

// app/code/local/Envato/Custompaymentmethod/controllers/PaymentController.php

class Envato_Custompaymentmethod_PaymentController extends Mage_Core_Controller_Front_Action

{

  public function gatewayAction()

  {

    if ($this->getRequest()->get("orderId"))

    {

      $arr_querystring = array(

        'flag' => 1,

        'orderId' => $this->getRequest()->get("orderId")

      );

       

      Mage_Core_Controller_Varien_Action::_redirect('custompaymentmethod/payment/response', array('_secure' => false, '_query'=> $arr_querystring));

    }

  }

  public function redirectAction()

  {

    $this->loadLayout();

    $block = $this->getLayout()->createBlock('Mage_Core_Block_Template','custompaymentmethod',array('template' => 'custompaymentmethod/redirect.phtml'));

    $this->getLayout()->getBlock('content')->append($block);

    $this->renderLayout();

  }

  public function responseAction()

  {

    if ($this->getRequest()->get("flag") == "1" && $this->getRequest()->get("orderId"))

    {

      $orderId = $this->getRequest()->get("orderId");

      $order = Mage::getModel('sales/order')->loadByIncrementId($orderId);

      $order->setState(Mage_Sales_Model_Order::STATE_PAYMENT_REVIEW, true, 'Payment Success.');

      $order->save();

       

      Mage::getSingleton('checkout/session')->unsQuoteId();

      Mage_Core_Controller_Varien_Action::_redirect('checkout/onepage/success', array('_secure'=> false));

    }

    else

    {

      Mage_Core_Controller_Varien_Action::_redirect('checkout/onepage/error', array('_secure'=> false));

    }

  }

}

app/design/frontend/base/default/template/custompaymentmethod/redirect.phtml

<?php

$order = new Mage_Sales_Model_Order();

$orderId = Mage::getSingleton('checkout/session')->getLastRealOrderId();

$order->loadByIncrementId($orderId);

?>

<h2><?php echo $this->__('Demo Payment Gateway') ?></h2>

<p>It's a demo page acting as a payment gateway interface! So don't worry you won't get charged :-)</p>

<form name="custompaymentmethod" method="post" action="<?php echo Mage::helper('custompaymentmethod')->getPaymentGatewayUrl(); ?>">

  <input type="hidden" name="orderId" value="<?php echo $orderId; ?>">

  <input type="submit" value="<?php echo $this->__('Make Payment') ?>" />

</form>
