symfony - 入力データを mysql のみに制限する方法 [a-zA-Z0-9_]

Question

FOSUserbundleとsymfony2でアプリケーションを作っています

ただし、ユーザーIDとして2バイト文字を入力できます。入力データを制限するにはどうすればよいですか。

I should check mysql level? or doctrine entity level ?

According to @ManseUK help,

I have tried like

use FOS\UserBundle\Entity\User as BaseUser;
use Doctrine\ORM\Mapping as ORM;
use Symfony\Component\Validator\Constraints as Assert;

class User extends BaseUser
{


 /**
 * @ORM\Column(type="string")
 *　@Assert\MaxLength(limit="10", message="The tel number is too long.")
 *  @Assert\Regex("/[0-9]/")
 */
protected $tel1;

if I put more than 10 characters or letters other than 0-9 ,it is inputted normally.

Could you find some hint?

I am using FOSUserBundle and SonataAdminBundle

So there are three points to edit user Entity data.

when edit user data in FOS\UserBundle\Controller\ProfileController

/**
 * Edit the user
 */
public function editAction()
{
    $user = $this->container->get('security.context')->getToken()->getUser();
    if (!is_object($user) || !$user instanceof UserInterface) {
        throw new AccessDeniedException('This user does not have access to this section.');
    }

    $form = $this->container->get('fos_user.profile.form');
    $formHandler = $this->container->get('fos_user.profile.form.handler');

    $process = $formHandler->process($user);
    if ($process) {
        $this->setFlash('fos_user_success', 'profile.flash.updated');

        return new RedirectResponse($this->getRedirectionUrl($user));
    }

    return $this->container->get('templating')->renderResponse(
        'FOSUserBundle:Profile:edit.html.'.$this->container->getParameter('fos_user.template.engine'),
        array('form' => $form->createView())
    );
}

When regist user data in FOS\UserBundle\Controller\RegitrationController

public function registerAction()
{
    $form = $this->container->get('fos_user.registration.form');
    $formHandler = $this->container->get('fos_user.registration.form.handler');
    $confirmationEnabled = $this->container->getParameter('fos_user.registration.confirmation.enabled');

    $process = $formHandler->process($confirmationEnabled);
    if ($process) {
        $user = $form->getData();

        $authUser = false;
        if ($confirmationEnabled) {
            $this->container->get('session')->set('fos_user_send_confirmation_email/email', $user->getEmail());
            $route = 'fos_user_registration_check_email';
        } else {
            $authUser = true;
            $route = 'fos_user_registration_confirmed';
        }

        $this->setFlash('fos_user_success', 'registration.flash.user_created');
        $url = $this->container->get('router')->generate($route);
        $response = new RedirectResponse($url);

        if ($authUser) {
            $this->authenticateUser($user, $response);
        }

        return $response;
    }

    return $this->container->get('templating')->renderResponse('FOSUserBundle:Registration:register.html.'.$this->getEngine(), array(
        'form' => $form->createView(),
    ));
}

When manage data in SonataAdminBundle

namespace Acme\AdminBundle\Controller;

use Symfony\Bundle\FrameworkBundle\Controller\Controller;

class DefaultController extends Controller
{
    public function indexAction($name)
    {
        return $this->render('AcmeAdminBundle:Default:index.html.twig', array('name' => $name));
    }
}

Thanks to @ManseUK

I have almost sloved the problem,but still mysterious thing remained.

 /**
 * @ORM\Column(type="string")
 * @Assert\MaxLength(limit="10", message="The tel number is too long.")
 * @Assert\Regex(
 *    pattern="/[0-9]/",groups={"Registration", "Profile"}
 * )
 */
protected $tel1; 

In a nutshell,

* @Assert\MaxLength(limit="10", message="The tel number is too long.")

works

but

 * @Assert\Regex(
 *    pattern="/[0-9]/",groups={"Registration", "Profile"}
 * )

dosen't work.

I can't put more than 10 letters,

but I can put other letters than [0-9] such as alphabet.
