大佬教程收集整理的这篇文章主要介绍了PHP-Phalcon验证表单字段而不保存到数据库,大佬教程大佬觉得挺不错的,现在分享给大家,也给大家做个参考。
<?PHP
use Phalcon\Mvc\Model\Criteria;
use Phalcon\Paginator\Adapter\Model as Paginator;
use Phalcon\Mvc\View;
class UsersController extends ControllerBase {
public function loginAction() {
if($this->request->isPost()) {
$user = new Users();
$validates = $user->validation($this->request->getPost());
// Now validation works fine, but cancelOnFail in model doesn't seems to work,
if($validates) {
echo 'valid inputs';
}
else {
print_r($user->getmessages());
// Now how can we show these error messages below the corresponding input fields in the view.
// we would also like to show error message as follows, if a field has more than one validation conditions,
// Eg: say username have notempty and valid e-mail validation set in model so if username is empty show only not empty message,
// similarly if username is not empty and if its not a valid e-mail , show not valid email message.
}
exit();
}
}
}

@H_801_0@我正在尝试从模型进行验证,如下所示
@H_801_0@
<?PHP
use Phalcon\Mvc\Model\Validator;
use Phalcon\Mvc\Model\Validator\PresenceOf;
use Phalcon\Mvc\Model\Validator\Email;
class Users extends \Phalcon\Mvc\Model {
public function validation() {
$this->validate(new PresenceOf(
array(
'field' => 'username',
'message' => 'Username is required.',
'cancelOnFail' => true
)
));
$this->validate(new Email(
array(
'field' => 'username',
'message' => 'Username must be a valid e-mail.'
)
));
$this->validate(new PresenceOf(
array(
'field' => 'password',
'message' => 'password is required.'
)
));
return $this->validationHasFailed() != true;
}
}
?>
@H_801_0@我的查看文件如下
@H_801_0@
<?PHP
echo $this->tag->form(array("users/login", "role" => "form"));
echo $this->tag->textField(array('username', 'class' => 'form-control', 'placeholder' => 'E-mail', 'type' => 'email', 'tabindex' => 1));
echo $this->tag->passwordField(array('password', 'class' => 'form-control', 'placeholder' => 'password', 'type' => 'password', 'tabindex' => 2));
echo $this->tag->submitButton(array('Login','class' => 'btn btn-sm btn-success btn-block', 'tabindex' => 5));
?>
</form>
@H_801_0@我如何实现以下目标,
@H_801_0@1)检查表单字段是否按照控制器中模型中的规定正确验证.
@H_801_0@2)我不想保存表单数据,仅对其进行验证.
@H_801_0@3)在视图的输入字段下方显示相应的错误消息.
@H_801_0@谢谢解决方法:
@H_801_0@您需要创建表单,绑定您的实体,然后根据请求进行验证.查看http://docs.phalconphp.com/en/latest/reference/forms.html#validation @H_801_0@编辑:要显示错误消息,您可以在控制器中执行此操作 @H_801_0@// ...
$messages = array();
foreach ($user->getmessages() as $messagE) {
$messages[$message->getField()] = $message->getmessage();
}
$this->view->messages = $messages;
//...
@H_801_0@现在您可以看到$messages.
@H_801_0@我认为您确实应该在这种情况下使用表格.您尝试验证模型中的用户登录,但这是一个简单的表单验证.在模型中,您可以验证应用程序中用户的业务规则.以上是大佬教程为你收集整理的PHP-Phalcon验证表单字段而不保存到数据库全部内容,希望文章能够帮你解决PHP-Phalcon验证表单字段而不保存到数据库所遇到的程序开发问题。
