在Magento中添加一个自己的支付模块----第二部分

这里我们将在订单确认时显示我们的支付模块，将我们支付字段的信息和订单信息放在一块；

需要创建的文件：

• app/code/local/Envato/Custompaymentmethod/Block/Form/Custompaymentmethod.php: 这个block文件为自定义支付方式指定一个模板文件，展示自定义支付方式的表格；
• app/design/frontend/base/default/template/custompaymentmethod/form/custompaymentmethod.phtml:这个是支付方式表格的模板文件；
• app/code/local/Envato/Custompaymentmethod/Model/Paymentmethod.php: 这个模型文件用来验证和保存自定义支付方式相关的字段信息；
• app/code/local/Envato/Custompaymentmethod/Block/Info/Custompaymentmethod.php: 在右边栏中给总结区设置必要信息。。。；It's a block file which will set up the necessary information for the summary section in the right side­bar.

创建 app/code/local/Envato/Custompaymentmethod/Block/Form/Custompaymentmethod.php

<?php

// app/code/local/Envato/Custompaymentmethod/Block/Form/Custompaymentmethod.php

class Envato_Custompaymentmethod_Block_Form_Custompaymentmethod extends Mage_Payment_Block_Form

{

  protected function _construct()

  {

    parent::_construct();

    $this->setTemplate('custompaymentmethod/form/custompaymentmethod.phtml');

  }

}

说明：指定配置自定义支付模块字段的模板文件；

 

创建 app/design/frontend/base/default/template/custompaymentmethod/form/custompaymentmethod.phtml

<div class="form-list" id="payment_form_<?php echo $this->getMethodCode() ?>" style="display:none;">

  <div>

    <label><?php echo $this->__('Custom Field One') ?>*</label>

    <span>

      <input type="text" title="<?php echo $this->__('Custom Field One') ?>" name="payment[custom_field_one]" value="<?php echo $this->htmlEscape($this->getInfoData('custom_field_one')) ?>" />

    </span>

  </div>

  <div>

    <label><?php echo $this->__('Custom Field Two') ?>*</label>

    <span>

      <input type="text" title="<?php echo $this->__('Custom Field Two') ?>" name="payment[custom_field_two]" value="<?php echo $this->htmlEscape($this->getInfoData('custom_field_two')) ?>" />

    </span>

  </div>

</div>

<div>

   <?php echo $this->getMethod()->getConfigData('message');?>

</div>

　　说明：之间创建过两个字段custom_field_one 和custom_field_two，在这里展示这两个字段；

创建 app/code/local/Envato/Custompaymentmethod/Model/Paymentmethod.php

<?php

// app/code/local/Envato/Custompaymentmethod/Model/Paymentmethod.php

class Envato_Custompaymentmethod_Model_Paymentmethod extends Mage_Payment_Model_Method_Abstract {

  protected $_code  = 'custompaymentmethod';

  protected $_formBlockType = 'custompaymentmethod/form_custompaymentmethod';

  protected $_infoBlockType = 'custompaymentmethod/info_custompaymentmethod';

  public function assignData($data)

  {

    $info = $this->getInfoInstance();   

    if ($data->getCustomFieldOne())

    {

      $info->setCustomFieldOne($data->getCustomFieldOne());

    }

    if ($data->getCustomFieldTwo())

    {

      $info->setCustomFieldTwo($data->getCustomFieldTwo());

    }

    return $this;

  }

  public function validate()

  {

    parent::validate();

    $info = $this->getInfoInstance();

    if (!$info->getCustomFieldOne())

    {

      $errorCode = 'invalid_data';

      $errorMsg = $this->_getHelper()->__("CustomFieldOne is a required field.\n");

    }

    if (!$info->getCustomFieldTwo())

    {

      $errorCode = 'invalid_data';

      $errorMsg .= $this->_getHelper()->__('CustomFieldTwo is a required field.');

    }

    if ($errorMsg)

    {

      Mage::throwException($errorMsg);

    }

    return $this;

  }

  public function getOrderPlaceRedirectUrl()

  {

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

  }

}

说明：

1、$_code定义了自定义支付方式的唯一码；

2、$_formBlockType定义了一个块，当自定义支付方式选中时显示的块文件；

3、$_infoBlockType定义了一个块，右边栏显示的信息；

4、validate是对自定义支付相关字段的校验；

5、assignData将支付信息与订单信息绑定在一块；

6、getOrderPlaceRedirectUrl客户订单提交后的跳转地址；

创建 app/code/local/Envato/Custompaymentmethod/Block/Info/Custompaymentmethod.php

<?php

// app/code/local/Envato/Custompaymentmethod/Block/Info/Custompaymentmethod.php

class Envato_Custompaymentmethod_Block_Info_Custompaymentmethod extends Mage_Payment_Block_Info

{

  protected function _prepareSpecificInformation($transport = null)

  {

    if (null !== $this->_paymentSpecificInformation)

    {

      return $this->_paymentSpecificInformation;

    }

    $data = array();

    if ($this->getInfo()->getCustomFieldOne())

    {

      $data[Mage::helper('payment')->__('Custom Field One')] = $this->getInfo()->getCustomFieldOne();

    }

    if ($this->getInfo()->getCustomFieldTwo())

    {

      $data[Mage::helper('payment')->__('Custom Field Two')] = $this->getInfo()->getCustomFieldTwo();

    }

    $transport = parent::_prepareSpecificInformation($transport);

    return $transport->setData(array_merge($data, $transport->getData()));

  }

}

说明：这个文件可以在订单确认页面的右侧显示相关的总结信息；

 

我们已经完成了订单确认的过程；用户确认提交，Magento会根据getOrderPlaceRedirectUrl中的地址进行跳转；
