不需要 Laravel 表單輸入

Question

我正在嘗試為我的用戶制作一個簡單的聯系表格，如果他們有一個訂單 ID 可以將它放在一個字段中。 否則我將它默認為“0”（可以說他們有問題）

所以這是我的代碼

Controller
<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use App\Http\Requests;
use App\ContactUS;

class ContactUSController extends Controller
{
    public function contactUS()
    {
        return view('contactUS');
    }

    public function contactUSPost(Request $request)
    {
        $this->validate($request, [
            'name' => 'required',
            'email' => 'required|email',
            'message' => 'required'
        ]);

        ContactUS::create($request->all());

        return back()->with('success', 'Thanks for contacting us! We will get back shortly.');
    }
}



View

    <div class="container">
        <h1>Contact US Form</h1>

        @if(Session::has('success'))
            <div class="alert alert-success">
                {{ Session::get('success') }}
            </div>
        @endif

        {!! Form::open(['route'=>'contactus.store']) !!}

        <div class="form-group {{ $errors->has('name') ? 'has-error' : '' }}">
            {!! Form::label('Name:') !!}
            {!! Form::text('name', old('name'), ['class'=>'form-control', 'placeholder'=>'Enter Name']) !!}
            <span class="text-danger">{{ $errors->first('name') }}</span>
        </div>

        <div class="form-group {{ $errors->has('email') ? 'has-error' : '' }}">
            {!! Form::label('Email:') !!}
            {!! Form::text('email', old('email'), ['class'=>'form-control', 'placeholder'=>'Enter Email']) !!}
            <span class="text-danger">{{ $errors->first('email') }}</span>
        </div>

        <div class="form-group">
            {!! Form::label('Order ID:') !!}
            {!! Form::number('orderId', old('orderId'), ['class'=>'form-control no-spinners', 'placeholder'=>'Do you have and order id?']) !!}

        </div>

        <div class="form-group {{ $errors->has('message') ? 'has-error' : '' }}">
            {!! Form::label('Message:') !!}
            {!! Form::textarea('message', old('message'), ['class'=>'form-control', 'placeholder'=>'Enter Message']) !!}
            <span class="text-danger">{{ $errors->first('message') }}</span>
        </div>

        <div class="form-group">
            <button class="btn btn-success">Contact US!</button>
        </div>

        {!! Form::close() !!}

Model

<?php

namespace App;

use Illuminate\Database\Eloquent\Model;

class ContactUS extends Model
{
    public $table = 'contact_us';

    public $fillable = ['name','email','message'];
}

Migration

class CreateContactUsTable extends Migration
{
    /**
     * Run the migrations.
     *
     * @return void
     */
    public function up()
    {
        Schema::create('contact_us', function (Blueprint $table) {
            $table->increments('id');
            $table->string('name');
            $table->string('email');
            $table->text('message');
            $table->integer('orderId')->default('0');
            $table->boolean('solved')->default(false);
            $table->timestamps();
        });
    }

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

所以問題是，當我不在字段OrderId上放置任何值時，它采用默認值0但如果我放置任何數值1 or 2 etc它仍會在我的數據庫中保存0 。

知道為什么會發生這種反應嗎？

Answer 1

允許批量分配模型中的orderId字段，

 public $fillable = ['name','email','message','orderId'];

Answer 2

正如 Deepak 在評論中所述，您可以檢查控制器中的 null 值：

$data=$request->all();
$data['orderId'] = $data['orderId'] == '' ? 'No Order ID Entered' : $data['orderId'];

或者，通過一些虛假的東西

$data=$request->all();
$data['orderId'] = $data['orderId'] == '' ? 0 : $data['orderId'];
