【问题描述】:
如果字段未通过验证,是否有办法在表单的输入字段下方显示错误消息?我可以以某种方式以显示表单的相同操作(在我的情况下为用户/索引)处理表单,然后将这些错误消息发送到查看吗?我所拥有的是:index.volt:
<div class="loginForm">
<form action=<?= $form->getAction(); ?> method="POST">
<label for="username">Username: </label>
<?= $form->render('username'); ?>
<br/>
<label for="password">Password: </label>
<?= $form->render('password'); ?>
<br>
<?= $form->render('login'); ?>
</form>
</div>
LoginForm.php:
<?php
use Phalcon\Forms\Form,
Phalcon\Forms\Element\Text,
Phalcon\Forms\Element\Password,
Phalcon\Forms\Element\Submit,
Phalcon\Validation\Validator\PresenceOf,
Phalcon\Validation\Validator\StringLength;
class LoginForm extends Form {
public function initialize()
{
$this->setAction('login');
$username = new Text('username');
$username->addValidator(new PresenceOf(array (
'message' => 'Can\'t be empty'
)));
$password = new Password('password');
$password->addValidator(new PresenceOf(array (
'message' => 'Can\'t be empty'
)));
$submit = new Submit('login', array('value' => 'Login'));
$this->add($username);
$this->add($password);
$this->add($submit);
}
}
和 UserController.php:
<?php
class UserController extends \Phalcon\Mvc\Controller
{
/**
* login form
* @var LoginForm
*/
private $_loginForm;
public function initialize()
{
$this->_loginForm = new LoginForm();
}
public function indexAction()
{
$this->view->setVar('form', $this->_loginForm);
}
public function loginAction()
{
if($this->request->isPost()) {
if (!$this->_loginForm->isValid($this->request->getPost())) {
foreach ($this->_loginForm->getMessages() as $message) {
echo $message. '<br />';
// redirect to User/index and pass error messages to view to display them to a user
}
}
}
}
}
编辑: 或者,在显示的同一操作上处理此表单会更好。我该怎么做?
