[英]SQLSTATE[23000]: Integrity constraint violation: 1048 laravel 5.7
我在 Laravel 5.7 中遇到錯誤：
Illuminate\Database\QueryException SQLSTATE[23000]：完整性約束違規：1048 列“名稱”不能為
created_at（SQL：插入stores（name，phone，matric，password？，更新時間？創建updated_at）， , ?, ?, 2019-10-01 16:29:49, 2019-10-01 16:29:49))
這是我的表格：
<!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">© 2017-2019</p>
</form>
</html>
這是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('/');
}
}
這是遷移：
<?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');
}
}
您正在嘗試在名稱列中保存 null 值，即使它是必需的。
您的 html 表單中缺少name屬性。 如果沒有此屬性，您的輸入數據將不會傳遞給 controller，因此您將獲得空值。 因此，將name屬性添加到輸入字段。
<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>
並更改您的驗證
$this->validate($request,[
'name'=> 'required',
'matric'=> 'required',
'phone'=> 'required',
'email'=>'required',
'password'=> 'required'
]);
您還可以采取以下步驟繞過 Laravel 網站中的此錯誤：-
在位於路徑\config\的database.php文件中更新'strict' => false
在位於路徑\app\Http\的Kernel.php文件中的語句下方評論
// \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,
希望它將來對某人有所幫助。
您應該使用name="namehere"命名您的輸入，例如
<input type="text" id="inputname" name="name" class="form-control" placeholder="Name" required>
