FOSuserBundle(发送邀请码给用户)

http://symfony.com/doc/master/bundles/FOSUserBundle/adding_invitation_registration.html

上面的构建实体注册服务之类的按照文档去操作。对应自己的地方稍加修改即可。

运用方法

public function inviteAction() {
    $em = $this->getDoctrine()->getManager();
    $invitation = new Invitation();
    $em->persist($invitation);
    // and then just output your $invitation->getCode() to user
    // also don‘t forget to check invitation as sent: $invitation->send()
}
