laravel 如何验证表单输入并插入数据库

Question

我正在尝试用 laravel 5.3 中的某些字段构建一个简单的注册表单，但在这样做时出现插入错误，以下是屏幕截图：

以下是我的 blade 文件：

@extends('admin.authlayouts')

@section('content')
<!-- Registration content -->
<div class="col-xs-12 login-content reg-content">
    <span class="text-center">Register to get your account</span>
    <div class="col-xs-12 login-form">
        <form role="form" method="POST" action="{{ url('/memberregister') }}">
          {{ csrf_field() }}

            <label>Enter your personal details below.</label>
            <div class="form-group{{ $errors->has('name') ? ' has-error' : '' }}">
                <label class="sr-only" for="full-name">Full name</label>
                <input type="text" name="name" id="name" value="{{ old('name') }}" placeholder="Full name" class="input-field full-name form-control" required autofocus>
              @if ($errors->has('name'))
                <span class="help-block">
                    <strong>{{ $errors->first('name') }}</strong>
                </span>
            @endif
            </div>
            <div class="form-group{{ $errors->has('email') ? ' has-error' : '' }}">
                <label class="sr-only" for="email">Email</label>

            </div>
            <div class="form-group{{ $errors->has('city') ? ' has-error' : '' }}">

以下是我的控制器：

public function memberregister(Request $request)
{
  $this->validate($request, User::$register_validation_rules);
  $data = $request->only('name', 'email', 'password', 'username', 'address', 'city', 'is_admin', 'contact');
  $data['password'] = bcrypt($data['password']);
  $data['is_admin'] = 0;
  $user = User::Create($data);
  if($user){
    \Auth::login($user);
    return redirect('member.dashbaord');
  }

  return back()->withInput();
}

以下是我的用户模型：

<?php

namespace App;

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;

class User extends Authenticatable
{
    use Notifiable;

    /**
     * The attributes that are mass assignable.
     *
     * @var array
     */
    protected $fillable = [
        'name', 'email', 'password', 'contact', 'address', 'city', 'country', 'username', 'bankname', 'bankaddress', 'ifsccode', 'accountnumber', 'is_admin'
    ];

    /**
     * The attributes that should be hidden for arrays.
     *
     * @var array
     */
    protected $hidden = [
        'password', 'remember_token',
    ];

    public static $login_validation_rules = [
      'username' => 'required|exists:user',
      'password' => 'required'

    ];

    public static $register_validation_rules = [
            'name' => 'required|max:255',
            'email' => 'required|email|max:255|unique:users',
            'username' => 'required|max:255|unique:users',
            'password' => 'required|min:6|confirmed',
//             'contact_number' => 'required',
            'address' => 'required|max:255',
            'city' => 'required|max:255',
//             'state' => 'required|max:255',
//             'country' => 'required|max:255'

    ];

}

请帮帮我。

谢谢。

Answer 1

在您的 User 模型中，$fillable 数组包含 country 列。但是您正在尝试创建新记录而不为 county 列插入任何值。

因此，在 users table 中创建记录时，您必须为 country 列定义一个默认值。

在您的 users 迁移文件中，将 country 列设置为可为空。

$table->string('country')->nullable();

Answer 2

看起来您的架构中有 "country" 并且它不可为 nullable() and/or 没有 default()，并且您没有从表单中提供该值。适当修复（使其可为空，为其设置默认值，向表单添加国家/地区字段）。

我在你的 memberregister() 方法中根本没有看到对 "country" 的引用

Answer 3

检查以下行

$data = $request->only('name', 'email', 'password', 'username', 'address', 'city','country', 'is_admin', 'contact');

请求中没有国家。您还需要添加国家/地区。
