在评论表单中添加自定义字段

Question

我期待在"评论"表单中创建自定义字段"电子邮件ID"和"一个"下拉列表.

我试过这个,但没有保存数据,它只是字段

应用程序\代码\核心\法师\评论\型号\ Mysql4\Review.php

protected function _afterSave(Mage_Core_Model_Abstract $object)
{
$detail = array(
'title' => $object->getTitle(),
'detail' => $object->getDetail(),
'nickname' => $object->getNickname(),
'email' => $object->getEmail(), // New field 1
'fname' => $object->getFname(), // New field 2
);

现在添加电子邮件,fname在数据库的review_detail表中也转到app\code\core\Mage\Adminhtml\Block\Review\Edit\Form.php也添加:

$fieldset->addField('fname', 'text', array( // New field 2
'label' => Mage::helper('review')->__('First Name'),
'required' => true,
'name' => 'fname'
));

$fieldset->addField('email', 'text', array( // New field 1
'label' => Mage::helper('review')->__('Email'),
'required' => true,
'name' => 'email'
));

之前

$fieldset->addField('nickname', 'text', array(
'label' => Mage::helper('review')->__('Nickname'),
'required' => true,
'name' => 'nickname'
));

修改Mage核心类有点吓人,将来很难升级magento核心类.您可以通过自己的自定义模块覆盖特定的类(如果要设置模块,请参阅模块创建者)

模块的config.xml,添加模型重写如下:

<global>
    <models>
        <review_mysql4>
            <rewrite>
                <review>[[Your Company]]_[[Your Module]]_Model_Review</review>
            </rewrite>
        </review_mysql4>
    </models>
    ...
</global>

并且指定的类将从您要覆盖的Magento核心类扩展:

class [[Your Company]]_[[Your Module]]_Model_Review
    extends Mage_Review_Model_Mysql4_Review
{
    protected function _afterSave(Mage_Core_Model_Abstract $object)
    {
     .... 
    }
}

PS.在magento review_detail表中添加新字段:

$installer = $this;
$installer->startSetup();
$installer->run("ALTER TABLE review_detail ADD COLUMN email VARCHAR(255) NULL");
$installer->endSetup();
