[英]Phalcon - validation in form
我创建了带有验证规则的表单。 一切都很好,形式可见并且有效。 问题出在验证器上。 只有第一个验证器在addValidators([ ....])
起作用
我的表单类源代码:
public function initialize()
{
$title = new Text('title');
$title->setLabel('Title of article');
$title->setFilters([
'striptags', 'trim'
]);
$title->addValidators([
new PresenceOf([
'message' => 'Title can not be empty'
]),
new StringLength([
'min' => 5,
'messageMinimum' => 'Title is too short. Should has more than 5 letters'
]),
new MYArticleAddCheckTitleValidator([
'message' => 'aaaaaaaaaaaaaaa'
])
]);
$this->add($title);
..........
Windows上的Phalcon版本2.0.4。
有什么建议或建议吗?
非常感谢。
解决此问题的最佳方法是使用Flash消息(类为Phalcon\\Flash\\Direct
。 您可以在此处找到文档。
我建议您查看phalcon vokuro项目使用此策略。
该解决方案的关键是表单类内部的message()
函数。
表格类
<?php
namespace Your\App\Forms;
use Phalcon\Forms\Form;
use Phalcon\Forms\Element\Text;
use Phalcon\Validation\Message;
use Phalcon\Validation\Validator\PresenceOf;
use Phalcon\Validation\Validator\StringLength;
use Your\App\Validation\MYArticleAddCheckTitleValidator;
class YourForm extends Form {
public function initialize()
{
$title = new Text('title');
$title->setLabel('Title of article');
$title->setFilters([
'striptags', 'trim'
]);
$title->addValidators([
new PresenceOf([
'message' => 'Title can not be empty'
]),
new StringLength([
'min' => 5,
'messageMinimum' => 'Title is too short. Should has more than 5 letters'
]),
new MYArticleAddCheckTitleValidator([
'message' => 'aaaaaaaaaaaaaaa'
])
]);
$this->add($title);
}
/**
* Prints messages for a specific element. Call it in the view
*/
public function messages($name)
{
if ($this->hasMessagesFor($name)) {
foreach ($this->getMessagesFor($name) as $message) {
$this->flash->error($message);
}
}
}
}
调节器
<?php
namespace Your\App;
use Your\App\YourForm;
class YourController extends ControllerBase
{
public function indexAction()
{
$form = new YourForm();
$this->view->form = $form;
if($this->request->hasQuery('title')){
if ($form->isValid($this->request->getQuery()) != false) {
// Code when form is valid
}
}
}
}
查看如果您遵循建议的架构,则应位于/app/views/your/index.html
<form method="GET" action="">
<?= $form->label('title') ?>
<?= $form->render('title')?>
<?= $form->messages('title') //show messages here ?>
</form>
如果您使用多种形式,则向DI
注册Flash服务非常有用。 定义服务时(可以在根文件夹中的index.php
或/app/config/
文件夹中的services.php
中),您可以定义Flash服务:
<?php
use Phalcon\DI\FactoryDefault;
$di = new FactoryDefault();
// Register the flash service with custom CSS classes
$di->set('flash', function () {
$flash = new Phalcon\Flash\Direct(
array(
'error' => 'your-error-class',
'success' => 'your-success-class',
'notice' => 'your-notice-class',
'warning' => 'your-warning-class'
)
);
return $flash;
});
