Login and registration form in Laravel 5
提问by mrakodol
I start to learn a new laravel and trying to learn it, by building small project, to make my starter site, but I have a problem. I only create new project without any plugin. I have a problem with login and register form. I put this into route file:
我开始学习一个新的 Laravel 并尝试通过构建小项目来学习它来制作我的入门网站，但我遇到了问题。我只创建没有任何插件的新项目。我在登录和注册表单方面遇到问题。我把它放到路由文件中：
get('user/login', 'Auth\AuthController@showLoginForm');
post('user/login', 'Auth\AuthController@postLogin');
get('user/register', 'Auth\AuthController@showRegistrationForm');
post('user/register', 'Auth\AuthController@register');
And make a login and register form. It shows me a forms, but I can't submit it and I do not know how to insert into database or how to validate user credentials. Can you tell me how to do it in new beta Laravel framework?
并制作登录和注册表格。它向我展示了一个表单，但我无法提交它，我不知道如何插入数据库或如何验证用户凭据。你能告诉我如何在新的 beta Laravel 框架中做到这一点吗？
Problem is that Laravel shows me a login and register form. But when I click submit it didn't do nothing, only refresh the page. I put method="POST" action="" into forms. When I change
问题是 Laravel 向我展示了一个登录和注册表单。但是当我点击提交时它什么也没做，只是刷新页面。我将 method="POST" action="" 放入表单中。当我改变
public function register(RegisterRequest $request)
into
进入
public function register()
in App\Http\Controllers\Auth\AuthController, when I submit form it give me an error that $request is not find.
在 App\Http\Controllers\Auth\AuthController 中，当我提交表单时，它给我一个错误，即找不到 $request。

This is how it works in Laravel 5 when you use request. If you inject Request object for example this way:
当您使用请求时，这就是它在 Laravel 5 中的工作方式。例如，如果您以这种方式注入 Request 对象：
public function register(RegisterRequest $request) {
// your code goes here
}
the code of this function won't be executed until RegisterRequestvalidate your data with success.
在RegisterRequest成功验证您的数据之前，不会执行此函数的代码。
Looking at your rules:
看看你的规则：
return [
'email' => 'required|email|unique:users',
'password' => 'required|confirmed|min:8',
];
you need to make sure your data pass those rules.
您需要确保您的数据通过这些规则。
You should also add to your form displaying errors:
您还应该添加到显示错误的表单中：
@foreach ($errors->all() as $error)
{{ $error }}
@endforeach
to display validation errors in form.
在表单中显示验证错误。

Everything seems to be fine in your code. Valid function is being launched. If you don't believe me, change your registerfunction into:
在您的代码中一切似乎都很好。正在启动有效功能。如果您不相信我，请将您的register功能更改为：
public function register()
{
return "This is register function";
}
The error you get is because if you remove RegisterRequest $requestfrom your function parameter, you cannot later use $request->email;because it's undefined
你得到的错误是因为如果你RegisterRequest $request从你的函数参数中删除，你以后不能使用，$request->email;因为它是未定义的
