php - Laravel 中的注册表单重定向到自身而不创建用户实例

问题描述

我一直在用 Laravel 创建一个注册表单，我使用默认的 Auth 表单，我只将类别添加到表单中，但我不知道为什么它一直将我重定向到注册表单，甚至没有创建用户实例，我检查User.php文件并将类别添加到错误数组中，也添加到用户迁移表中，但仍然无法正常工作

这是我的register.blade.php文件：

@extends('layouts.app')

<!-- Fetching the categories from the DATABASE -->

<?php 
use Illuminate\Support\Facades\DB;
    $categories = DB::table('static_categories')->get();
?>

<!-- **************************************************** -->

@section('content')

<div class="container">

    <div class="row justify-content-center">
        <div class="col-md-8">
            <div class="card">
                <div class="card-header">{{ __('Register') }}</div>

                <div class="card-body">
                    <form method="POST" action="{{ route('register') }}" aria-label="{{ __('Register') }}">
                        @csrf

                        <div class="form-group row">
                            <label for="name" class="col-md-4 col-form-label text-md-right">{{ __('Name') }}</label>

                            <div class="col-md-6">
                                <input id="name" type="text" class="form-control{{ $errors->has('name') ? ' is-invalid' : '' }}" name="name" value="{{ old('name') }}" required autofocus>

                                @if ($errors->has('name'))
                                    <span class="invalid-feedback" role="alert">
                                        <strong>{{ $errors->first('name') }}</strong>
                                    </span>
                                @endif

这是我的用户迁移文件：

<?php

use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateUsers extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('users', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('email')->unique();
            $table->string('password');
            $table->rememberToken();
            $table->timestamps();
            $table->integer('cat')->unsigned();
            $table->foreign('cat')->references('cat_id')->on('static_categories');
        });
    }

    /**
     * Reverse the migrations.
     *
     * @return void
     */
    public function down()
    {
        Schema::dropIfExists('users');
    }
}

这是我的 registerController 文件：

<?php

namespace App\Http\Controllers\Auth;

use App\User;
use App\Http\Controllers\Controller;
use Illuminate\Support\Facades\Hash;
use Illuminate\Support\Facades\Validator;
use Illuminate\Foundation\Auth\RegistersUsers;

class RegisterController extends Controller
{
    use RegistersUsers;

    /**
     * Where to redirect users after registration.
     *
     * @var string
     */
    protected $redirectTo = '/home';

    /**
     * Create a new controller instance.
     *
     * @return void
     */
    public function __construct()
    {
        $this->middleware('guest');
    }

    /**
     * Get a validator for an incoming registration request.
     *
     * @param  array  $data
     * @return \Illuminate\Contracts\Validation\Validator
     */
    protected function validator(array $data)
    {
        return Validator::make($data, [
            'name' => 'required|string|max:255',
            'email' => 'required|string|email|max:255|unique:users',
            'password' => 'required|string|min:6|confirmed',
            'cat' => 'required|integer'
        ]);
    }

    /**
     * Create a new user instance after a valid registration.
     *
     * @param  array  $data
     * @return \App\User
     */
    protected function create(array $data)
    {

        return User::create([
            'name' => $data['name'],
            'email' => $data['email'],
            'password' => Hash::make($data['password']),
            'cat' => $data['cat'],
        ]);
    }
}

非常感谢提前！不要介意发布这个问题的糟糕方式，这是我第一次！

解决方案

您缺少类别字段的名称。

<select name="cat"></select>

这就是为什么它没有按要求进行。在 laravel 中，您必须为输入字段命名，否则将被省略。我会建议，每当您遇到这种情况时，然后转储数据，例如

dd($request->all();

看看是否需要数据。

对您的问题的回答是： laravel 正在重定向，因为您在验证中有必需的类别字段，并且您没有将其发送到服务器，因为缺少字段名称。如果您在选择标签下方添加此代码，您可能会看到错误

@if ($errors->has('cat'))
     <span class="invalid-feedback" role="alert">
          <strong>{{ $errors->first('cat') }}</strong>
     </span>
@endif
