SQLSTATE[23000]：违反完整性约束：1048 laravel 5.7

Question

我在 Laravel 5.7 中遇到错误：

Illuminate\Database\QueryException SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'name' cannot be null (SQL: insert into stores (name, matric, phone, email, password, updated_at, created_at) values (?, ?, ?, ?, ?, 2019-10-01 16:29:49, 2019-10-01 16:29:49))

这是我的表格：

<!DOCTYPE html>
<html>
<head>
    @section('title', 'Sign up for customer page')
</head>
<body class="text-center">
@extends('layout.app')

@section('content')

@endsection
@include('include.navbar')
<form class="form-signup" action="{{URL:: to('/store')}}" method="post">
  @csrf

  <h1 class="h3 mb-3 font-weight-normal">Please sign up as customer</h1>
  <label for="inputname" class="sr-only">Name</label>
  <input type="text" id="inputname" class="form-control" placeholder="Name" required>
  <label for="inputmatric" class="sr-only">ID matric</label>
  <input type="text" id="inputmatric" class="form-control" placeholder="ID matric" required>
  <label for="inputphon" class="sr-only">Phone No</label>
  <input type="text" id="inputphon" class="form-control" placeholder="Phone No" required>
  <label for="inputemail" class="sr-only">E-mail</label>
  <input type="text" id="inputemail" class="form-control" placeholder="E-mail" required>
  <label for="inputpassword" class="sr-only">Password</label>
  <input type="text" id="inputpassword" class="form-control" placeholder="Password" required>


  <button class="btn btn-lg btn-primary btn-block"  type="submit">Sign up</button>
  <p class="mt-5 mb-3 text-muted">&copy; 2017-2019</p>
</form>

</html>

这是UserController:

namespace App\Http\Controllers;
use App\Http\Controllers\Controller;
use Illuminate\Http\Request;
use Illuminate\Support\Facades\URL;
use Illuminate\Support\Facades\DB;
use App\store;//model name

class UserController extends Controller
{
    public function store(Request $request)
    {

        $this->validate($request,[
            'name'=> 'request',
            'matric'=> 'request',
            'phone'=> 'request',
            'email'=>'request',
            'password'=> 'request'

        ]);

        //store new customer
        $store = new store;   // valible and model name
        $store-> name = $request->input('name');
        $store-> matric = $request->input('matric');
        $store-> phone = $request->input('phone');
        $store-> email = $request->input('email');
        $store-> password = $request->input('password');

        //save new customer
        $store-> save();

        //redirect
        return redirect('/');
    }
}

这是迁移：

<?php
//create the customer table
use Illuminate\Support\Facades\Schema;
use Illuminate\Database\Schema\Blueprint;
use Illuminate\Database\Migrations\Migration;

class CreateStoresTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('stores', function (Blueprint $table) {
            $table->bigIncrements('id');
            $table->string ('name');
            $table->integer ('matric');
            $table->string ('phone');
            $table->string ('email');
            $table->string ('password');
            $table->timestamps();
        });
    }

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

Answer 1

您正试图在名称列中保存空值，尽管它是必需的。

Answer 2

您的 html 表单中缺少 name 属性。如果没有此属性，您的输入数据将不会传递给控制器，因此您将获得空值。因此，将 name 属性添加到输入字段。

<label for="inputname" class="sr-only">Name</label>
<input type="text" id="inputname" name="name" class="form-control" placeholder="Name" required>
<label for="inputmatric" class="sr-only">ID matric</label>
<input type="text" id="inputmatric" name="matric" class="form-control" placeholder="ID matric" required>
<label for="inputphon" class="sr-only">Phone No</label>
<input type="text" id="inputphon" name="phone" class="form-control" placeholder="Phone No" required>
<label for="inputemail" class="sr-only">E-mail</label>
<input type="text" id="inputemail" name="email" class="form-control" placeholder="E-mail" required>
<label for="inputpassword" class="sr-only">Password</label>
<input type="text" id="inputpassword" name="password" class="form-control" placeholder="Password" required>

同时更改您的验证

$this->validate($request,[
    'name'=> 'required',
    'matric'=> 'required',
    'phone'=> 'required',
    'email'=>'required',
    'password'=> 'required'
]);

Answer 3

您应该用 name="namehere" 命名您的输入例如

<input type="text" id="inputname" name="name" class="form-control" placeholder="Name" required>

Answer 4

您还可以采取以下步骤在您的 Laravel 网站中绕过此错误：-

更新位于路径 \config\
的 database.php 文件中的 'strict' => false
在位于路径 \app\Http\
的 Kernel.php 文件中的语句下方注释

// \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,

希望对以后的人有所帮助。

Answer 5

您可能以文本格式发送数据：
