我试图从我的控制器添加一个验证,如下所示。但它总是显示这个
if ($request->getPost('ownerType') == "Company") {
$form->getInputFilter()->get('companyName')->getValidatorChain()->addValidator('required');
}
显示错误。我对以下错误感到困惑。
Catchable fatal error: Argument 1 passed to Zend\Validator\ValidatorChain::addValidator() must implement interface Zend\Validator\ValidatorInterface, string given, called in E:\xampp\htdocs\hossbrag\module\WebApp\src\WebApp\Controller\JobController.php on line 177 and defined in E:\xampp\htdocs\hossbrag\vendor\zendframework\zendframework\library\Zend\Validator\ValidatorChain.php on line 100
我的控制器在这里
<?php
namespace WebApp\Controller;
use Zend\Mvc\Controller\AbstractActionController;
use Zend\View\Model\ViewModel;
use WebApp\Entity\User;
use Zend\View\Model\JsonModel;
use vendor\mpdf\mpdf;
class JobController extends AuthenticatedController
{
public function createAction()
{
$form = new \WebApp\Form\JobpostingForm();
$form->get('companyName')->setValueOptions($company);
$checkAgreement = true;
$request = $this->getRequest();
if ($request->getPost('ownerType') == "Company") {
$form->getInputFilter()->get('companyName')->getValidatorChain()->addValidator('required');
}
}
}
应该在我的控制器中更改什么以获得适当的解决方案。
