Validation

Validation is supported by default using the Symfony validation library.

Simplest way to validate your fields is to use assertion annotations.

Examples

Assert that $firstName is not empty:

use Symfony\Component\Validator\Constraints as Assert;
...
/**
 * @ORM\Column(name="FirstName", type="string", length=40)
 * @Assert\NotBlank()
 */
protected $firstName;

Assert $email is not empty:

/**
 * @ORM\Column(name="email", type="string", length=150)
 * @Assert\Email(message="Not valid email")
 */
protected $email;
