Symfony how to validate an EmailType by not allowing emails without an ending dot something

Currently the EmailType of Symfony allows any email like:

"whatever@domain"

So there is no validation against the domain of the email

what is the best way to make it accepts only email like:

"whatever@domain.something"

so that the domain should contain at least one dot.

Since it should be a common issue, I was wondering if there's already a built-in way to accomplish it.

Solution

  • Use Email constraint to validate email values correctly:

    use Symfony\Component\Validator\Constraints as Assert;

class User 
{
    /**
     * @var string
     *
     * @Assert\Email()
     */
    private $email;
}

    On submit the form the EmailValidator checks whether this '/^.+\@\S+\.\S+$/' pattern is valid or not, and throws a violation constraint if not.
