like sending them an email, etc// maybe set a flash success message for the userreturn $this-redirectToRoute(replace_with_some_route);}return $this-render(registration/register.html.twig,array(form $form-createView()));}}在安全配置中配置上面步骤3的编码器来定义用于编译密码的算法1234# app/config/security.ymlsecurity:encoders:AppBundle\Entity\User:bcrypt1234567891011xmlns:xsihttp://www.w3.org/2001/XMLSchema-instancexmlns:srvhttp://symfony.com/schema/dic/servicesxsi:schemaLocationhttp://symfony.com/schema/dic/services http://symfony.com/schema/dic/services/services-1.0.xsdbcrypt123456// app/config/security.php$container-loadFromExtension(security, array(encoders array(AppBundle\Entity\User bcrypt,),));这个案例我们推荐使用bcrypt 算法。了解更多关于如何编码用户密码的细节请看安全章节。如果您决定不使用注释方式的路由(如上)那么你需要创建一个这个控制器的路由1234# app/config/routing.ymluser_registration:path: /registerdefaults:{ _controller:AppBundle:Registration:register }12345678910xmlns:xsihttp://www.w3.org/2001/XMLSchema-instancexsi:schemaLocationhttp://symfony.com/schema/routing http://symfony.com/schema/routing/routing-1.0.xsdAppBundle:Registration:register12345678910// app/config/routing.phpuse Symfony\Component\Routing\RouteCollection;use Symfony\Component\Routing\Route;$collection new RouteCollection();$collection-add(user_registration, new Route(/register, array(_controller AppBundle:Registration:register,)));return $collection;下一步创建模板12345678910{# app/Resources/views/registration/register.html.twig #}{{ form_start(form) }}{{ form_row(form.username) }}{{ form_row(form.email) }}{{ form_row(form.plainPassword.first) }}{{ form_row(form.plainPassword.second) }}Register!{{ form_end(form) }}1234567891011?php echo $view[form]-start($form) ??php echo $view[form]-row($form[username]) ??php echo $view[form]-row($form[email]) ??php echo $view[form]-row($form[plainPassword][first]) ??php echo $view[form]-row($form[plainPassword][second]) ?Register!?php echo $view[form]-end($form) ?参见如何自定义表单渲染里面有更多细节。更新你的数据库结构 ¶如果你在这个教程中已经更新了User实体你必须要使用下面的命令去更新数据库结构1$ php bin/console doctrine:schema:update --force就是这样来到/register来尝试一下吧注册表单只有Email(没有 Username) ¶如果你想要你的用户通过email登录并不需要用户名那么你可以从你的User实体中彻底移除他。相反让getUsername()返回email属性1234567891011121314// src/AppBundle/Entity/User.php// ...class User implements UserInterface{// ...public function getUsername(){return $this-email;}// ...}下一步只更改你security.yml文件的providers 部分以便Symfony知道如何去通过email属性加载你的用户来登录。参见如何自定义表单渲染。添加一个“打上勾”的Checkbox ¶有时你想要一个“你接受这个条款和声明吗”的Checkbox出现在你的注册表单。唯一窍门让你要去添加这个字段到你的表单中而你永远不需要添加多余的termsAccepted属性到你的User实体。要做到这一点要添加一个termsAccepted字段到你的表单但设置它的 mapped 选项为false:1234567891011121314151617181920// src/AppBundle/Form/UserType.php// ...use Symfony\Component\Validator\Constraints\IsTrue;use Symfony\Component\Form\Extension\Core\Type\CheckboxType;use Symfony\Component\Form\Extension\Core\Type\EmailType;class UserType extends AbstractType{public function buildForm(FormBuilderInterface $builder, array $options){$builder-add(email, EmailType::class);// ...-add(termsAccepted, CheckboxType::class, array(mapped false,constraints new IsTrue(),)));}}constraints配置也被使用了它允许我们添加验证尽管没有User中没有termsAccepted属性。
