Add custom field in review form

Question

I want to add a custom field to the review form in Magento. I have tried this but the data is not saved, it shows the field.

app\code\core\Mage\Adminhtml\Block\Review\Edit\Form.php

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

After

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

app\design\frontend\theme\theme\template\review\form.phtml

        <li class="formlistreview">
            <label for="email_field" class="required"><em>*</em><?php echo $this->__('E-mail') ?></label>
            <div class="input-box">
                <input type="text" name="email" id="email_field" class="input-text required-entry" value="<?php echo $this->htmlEscape($data->getEmail()) ?>" />
            </div>
        </li>

app\code\core\Mage\Review\Model\Resource\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
);

What am I missing?

Answer 1

use $this instead of $object

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

Answer 2

You need to do is add a column email in review_detail table. Then this issue would be resolved.

It's too old post, but it might help someone. So, i just figured out the solution.
