提交带有验证码的表单后，预先填充magento表单

我已经在magento中创建了自定义表单扩展。提交表单后，如果验证码不正确，如何预先填充表单值。表单将不会保存在后端。这是我的控制器文件

类名称空间\u模块名称\u索引控制器扩展

}验证码检查和重定向之前。您可以将提交的数据保存在注册表中。您可以在表单详细信息页面上访问保存的注册表数据

发送电子邮件时，可以删除注册表数据

$post = $this->getRequest()->getPost();

寄存器变量

Mage::register('name', $post['name']);
Mage::register('email', $post['email']);
Mage::register('message', $post['message']);

Mage::unregister('name');
Mage::unregister('email');
Mage::unregister('message');

使用下面的方法获取模板中的注册表变量值

Mage::registry('name');
Mage::registry('email');
Mage::registry('message');

销毁/注销变量

Mage::register('name', $post['name']);
Mage::register('email', $post['email']);
Mage::register('message', $post['message']);

Mage::unregister('name');
Mage::unregister('email');
Mage::unregister('message');

在哪里调用magento控制器操作中的寄存器变量。我已经调用了postAction（）方法。但是它不起作用。你可以在这行下面$captchaModel=Mage:：helper（'captcha'）->getCaptcha（$formId）；
