Question

我将username用作id进行登录，并将用户名和电子邮件设置为唯一。每当我输入用户名和电子邮件时，验证规则都会检查即将到来的数据，并且没有问题，因为username和email是新的且唯一的。我更新时会出现问题。更新属性时，不需要主要更改用户名，但是规则要求使用unique, username。 使用验证规则更新唯一属性的最佳做法是什么？。

更新用户方法

 public function updateUser($req, $id)
    {
        $user = User::where('user_id', $id)->firstOrFail();
        $user->username = $req->input('username');
        $user->password = Hash::make($req->input('password'));
        $user->email = $req->input('email');
        $user->first_name = $req->input('first_name');
        $user->last_name = $req->input('last_name');
        $user->phone = $req->input('phone');
        $user->emergency_phone = $req->input('emergency_phone');
        $user->profile_photo = $req->input('profile_photo');
        $user->role = $req->input('role');
        $user->status = $req->input('status');

        $user->save();
        return $this->filterUsers([$user]);
    }

规则

  protected $rules = [

        'username' => 'required|max:20|unique:users',
        'email' => 'required|string|email|max:255|unique:users',
        'password' => 'required',
        // **in Production **
        // 'password' => [
        //     'required',
        //     'min:6',
        //     'regex:/^.*(?=.{3,})(?=.*[a-zA-Z])(?=.*[0-9])(?=.*[\d\X])(?=.*[!$#%]).*$/',
        //     'confirmed'
        // ],
        /**
         * Three of the five rules. 
         * English uppercase characters (A – Z)
         * English lowercase characters (a – z)
         * Base 10 digits (0 – 9)
         * Non-alphanumeric (For example: !, $, #, or %)
         * Unicode characters
         */

        'first_name' => 'required|string|max:255',
        'last_name' => 'required|string|max:255',
        'phone' => 'required|regex:/^([0-9\s\-\+\(\)]*)$/|min:5',
        'role' => 'required'


    ];

Answer 1

At edit time it will check for a unique username so we avoid unique for a current edit id

In the update method your validation rules as per below:

protected $rules = [
        'username' => 'required|max:20|unique:users,username,' . $id',
        'email' => 'required|string|email|max:255|unique:users,email,' . $id',
        'password' => 'required',
        'first_name' => 'required|string|max:255',
        'last_name' => 'required|string|max:255',
        'phone' => 'required|regex:/^([0-9\s\-\+\(\)]*)$/|min:5',
        'role' => 'required'
    ];

Answer 2

您可以使用

'username' => 'required|max:20|unique:users,username,' . $id',

如果您的用户表的主键是id，如果它是user_id之类的东西，那么它将变成

'username'  =>  'required|email|unique:user,username,' . $request->input('user_id') . ',userid',

所以语法是

'input_field' => 'unique:<table name>,<column name for this input field>, <unique id>, <unique id column in table>';

Answer 3

您需要在控制器Use Validator;中使用laravel验证程序类

并使用类似这样的内容：

$error = Validator::make($req->all(), $rules);
