在Laravel 5.4

Question

我现在正在使用全新安装的Laravel 5.4，我还安装了https://github.com/appzcoder/crud-generator。我使用生成器生成了Tickets CRUD。我能够发布＆＃34;门票＆＃34;使用＆＃34; php artisan migrate＆＃34;

将表转换为mysql数据库

如果其中一个文本输入缺少输入，我目前无法尝试显示$ errors。

TicketsController.php

    <?php

namespace App\Http\Controllers\Users;

use App\Http\Requests;
use App\Http\Controllers\Controller;

use App\Ticket;
use Illuminate\Http\Request;
use Session;

class TicketsController extends Controller
{
    /**
     * Display a listing of the resource.
     *
     * @return \Illuminate\View\View
     */
    public function index(Request $request)
    {
        $keyword = $request->get('search');
        $perPage = 25;

        if (!empty($keyword)) {
            $tickets = Ticket::where('user_id', 'LIKE', "%$keyword%")
                ->orWhere('subject', 'LIKE', "%$keyword%")
                ->orWhere('description', 'LIKE', "%$keyword%")

                ->paginate($perPage);
        } else {
            $tickets = Ticket::paginate($perPage);
        }

        return view('user.tickets.index', compact('tickets'));
    }

    /**
     * Show the form for creating a new resource.
     *
     * @return \Illuminate\View\View
     */
    public function create()
    {
        return view('user.tickets.create');
    }

    /**
     * Store a newly created resource in storage.
     *
     * @param \Illuminate\Http\Request $request
     *
     * @return \Illuminate\Http\RedirectResponse|\Illuminate\Routing\Redirector
     */
    public function store(Request $request)
    {

        $requestData = $request->all();

        Ticket::create($requestData);

        Session::flash('flash_message', 'Ticket added!');

        return redirect('tickets');
    }


}

查看

        <div class="panel panel-default">
            <div class="panel-heading">Create New Ticket</div>
            <div class="panel-body">
                <a href="{{ url('/tickets') }}" title="Back"><button class="btn btn-warning btn-xs"><i class="fa fa-arrow-left" aria-hidden="true"></i> Back</button></a>
                <br />
                <br />

                @if ($errors->any())
                    <ul class="alert alert-danger">
                        @foreach ($errors->all() as $error)
                            <li>{{ $error }}</li>
                        @endforeach
                    </ul>
                @endif

                {!! Form::open(['url' => '/tickets', 'class' => 'form-horizontal', 'files' => true]) !!}

                @include ('user.tickets.form')

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

            </div>
        </div>

form.blade.php

<div class="form-group {{ $errors->has('user_id') ? 'has-error' : ''}}">
    {!! Form::label('user_id', 'User Id', ['class' => 'col-md-4 control-label']) !!}
    <div class="col-md-6">
        {!! Form::number('user_id', null, ['class' => 'form-control']) !!}
        {!! $errors->first('user_id', '<p class="help-block">:message</p>') !!}
    </div>
</div><div class="form-group {{ $errors->has('subject') ? 'has-error' : ''}}">
    {!! Form::label('subject', 'Subject', ['class' => 'col-md-4 control-label']) !!}
    <div class="col-md-6">
        {!! Form::text('subject', null, ['class' => 'form-control']) !!}
        {!! $errors->first('subject', '<p class="help-block">:message</p>') !!}
    </div>
</div><div class="form-group {{ $errors->has('description') ? 'has-error' : ''}}">
    {!! Form::label('description', 'Description', ['class' => 'col-md-4 control-label']) !!}
    <div class="col-md-6">
        {!! Form::text('description', null, ['class' => 'form-control']) !!}
        {!! $errors->first('description', '<p class="help-block">:message</p>') !!}
    </div>
</div>

<div class="form-group">
    <div class="col-md-offset-4 col-md-4">
        {!! Form::submit(isset($submitButtonText) ? $submitButtonText : 'Create', ['class' => 'btn btn-primary']) !!}
    </div>
</div>

如果没有输入主题文字输入，我会收到页面错误提示：

SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'subject' cannot be null (SQL: insert into `tickets` (`user_id`, `subject`, `description`, `updated_at`, `created_at`) values (1, , dsa, 2017-03-08 13:05:22, 2017-03-08 13:05:22))

而不是$ errors功能

我需要在TicketsController中包含一些内容吗？和中间件？

感谢任何帮助。

Answer 1

对于这项工作，

$this->validate($request, [
    'subject' => 'required',
]);

在动作方法中写上面的代码，然后检查。

以下是您可以预先形成validation in laravel

的方法
