【问题描述】：

您好，我在 Laravel 项目中工作，我正在使用 js 验证器来验证表单文件，但如果我使用 unique:users 验证规则，则同样无法正常工作。我想要提交独特的电子邮件。如果我使用它，我将无法提交表单本身。所有其他验证规则都正常工作。

请帮我找出问题

以下是 UserController 中的代码，我应用了验证规则

<?php

namespace App\Http\Controllers;
use App\Http\Controllers;
use Illuminate\Http\Request;
use JsValidator;
use Validator;
use App\User;
use Illuminate\Support\Facades\Hash;
use App\Mail\WelcomeMail;
use Illuminate\Support\Facades\Mail;
use DB;
use Session;
use Redirect;
use Carbon\Carbon;
use App\Libraries\GlobalHelpers;
use App\Libraries\ImageHelpers;
use Auth;
use Response;


class UserController extends Controller
{
    protected $userValidationRules = [
        'user_name' => 'required',
        'email' => 'required|email|max:255|unique:users',
    ];
 public function addUsers()
    {
        $validator = JsValidator::make($this->userValidationRules,[],[],'#addusers');
        return view('user.add')->with(['validator' => $validator]);
    }
}

以下是视图文件中的代码

@extends('user.layout.app')

@section('content')
    <script src="{{ url('js/user/location.js') }}"></script>
    <div class="container-fluid add-location">
        <div class="row">
            <div class="col-md-12">
                <div class="card">
                    <form method="post"  action="{{ route('storeUsers') }}" name="addusers" id="addusers" enctype="multipart/form-data" novalidate>
                        {{ csrf_field() }}
                        <div class="card-header">
                            <h4 class="card-title"> Add Users </h4>
                        </div>
                        @if(!empty($errors->all()))
                            <div class="row"> @foreach ($errors->all() as $error)
                                    <div class="col-lg-12">
                                        <div class="alert alert-danger"> <span>{{ $error }}</span> </div>
                                    </div>
                                @endforeach </div>
                        @endif
                        <div class="card-content">

                                </div>

什么问题，为什么唯一验证不起作用？

【问题讨论】：

'email' =>'required|string|email|max:255|unique:users,email',
不，它不工作

标签： php laravel

【解决方案1】：

protected $userValidationRules = [
        'user_name' => 'required',
        'email' => 'required|email|max:255|unique:users,email',
    ];

独特的：表，列根据 https://laravel.com/docs/6.x/validation#rule-unique

【讨论】：

【解决方案2】：

提交存储的时候还需要通过验证规则，只有它会检查

$this->validate($request, [
            'email' => 'required|email|max:255|unique:users'
        ]);
