User ID parameter in Laravel Request
提问by Ebuen Clemente Jr.
I have an admin where he is able to create and update users. I made a new Form request called 'UserUpdateRequest'. How can I pass the user id so that it can update user detail? Here are my rules:
我有一个管理员，他可以在其中创建和更新用户。我提出了一个名为“UserUpdateRequest”的新表单请求。如何传递用户 ID 以便它可以更新用户详细信息？这是我的规则：
// UserUpdateRequest
public function rules()
{
return [
'firstname' => 'required|min:2|max:255',
'lastname' => 'required|min:2|max:255',
'username' => 'required|max:255',
'password' => 'required|min:6|confirmed',
'email' => 'required|email|max:255|unique:users,email,????',
'contact' => 'required|integer',
'gender' => 'required|in:m,f',
'role_id' => 'required|exists:roles,id',
];
}
// Controller
public function update(UserUpdateRequest $request, User $user)
{
$user->update([
'firstname' => request('firstname'),
'lastname' => request('lastname'),
'username' => request('username'),
'email' => request('email'),
'contact' => request('contact'),
'gender' => request('gender'),
'role_id' => request('role_id'),
]);
session()->flash('message', 'User has been successfully added.');
return redirect('/users/' . $user->id);
}
'required|email|max:255|unique:users,email,????',is where I am confused.
'required|email|max:255|unique:users,email,????',是我困惑的地方。

看法：
<input type="hidden" value="{{ $user->id }}" name="user_id">
Controller:
控制器：
public function rules()

$id = $this->request->get('user_id');
return [

Since admin is changing users I assume you already have user data on your view file.
由于管理员正在更改用户，因此我假设您的视图文件中已经有了用户数据。
you can pass a hidden input on your form.
您可以在表单上传递隐藏的输入。
<input type="hidden" value="{{$user->id}}" name="user_id" />
and then receive it on your controller.
然后在您的控制器上接收它。
$user_id = $request->input('user_id');
$user = \App\User::find($user_id);
//validation comes here
Edit Depending on new information
根据新信息编辑
public function update(UserUpdateRequest $request, User $user)
should be
应该
public function update(Request $request, User $user)
and you have to call Request on your controller;
你必须在你的控制器上调用 Request ；
use Illuminate\Http\Request;
after that you can get your request as
之后你可以得到你的请求
dd($request->all());
but if you are using a special request post your UserUpdateRequestclass.
但如果您使用特殊请求，请发布您的UserUpdateRequest类。

Pass the userId as in hidden input field and use in the unique validation like
在隐藏输入字段中传递 userId 并在唯一验证中使用，如
unique:users,email,userId
