Question

说明：

我从https://laravelcollective.com/docs/5.4/html下载并安装了Form，并按照说明配置了所有文件。

  Collective\Html\HtmlServiceProvider::class,

        'Form' => Collective\Html\FormFacade::class,
        'Html' => Collective\Html\HtmlFacade::class,

问题：

我的路线http://127.0.0.1:8000/admin/product/create显示空白页。实际上，它应该向我显示一个表格。在所有代码或本地主机中都没有任何错误消息。

HTML代码：

@extends('admin.layout.admin')

@section('content')

    <h3>Add Product</h3>

    <div class="row">
        <div class="col-md-8 col-md-offset-2">
            {!! Form::open(['route' => 'product.store', 'method' => 'POST', 'files' => true, 'data-parsley-validate'=>'']) !!}

            <div class="form-group">
                {{ Form::label('name', 'Name') }}
                {{ Form::text('name', null, array('class' => 'form-control','required'=>'','minlength'=>'5')) }}
            </div>

            <div class="form-group">
                {{ Form::label('description', 'Description') }}
                {{ Form::text('description', null, array('class' => 'form-control')) }}
            </div>
            <div class="form-group">
                {{ Form::label('price', 'Price') }}
                {{ Form::text('price', null, array('class' => 'form-control')) }}
            </div>

            <div class="form-group">
                {{ Form::label('size', 'Size') }}
                {{ Form::select('size', [ 'small' => 'Small', 'medium' => 'Medium','large'=>'Large'], null, ['class' => 'form-control']) }}
            </div>

            <div class="form-group">
                {{ Form::label('category_id', 'Categories') }}
                {{ Form::select('category_id', $categories, null, ['class' => 'form-control','placeholder'=>'Select Category']) }}
            </div>

            <div class="form-group">
                {{ Form::label('image', 'Image') }}
                {{ Form::file('image',array('class' => 'form-control')) }}
            </div>

             {{ Form::submit('Create', array('class' => 'btn btn-default')) }}
            {!! Form::close() !!}

        </div>
    </div>

Answer 1

您的create()为空，因此不会显示任何内容。应该是这样

 public function create()
 {
   return view('form');
 }

form是您视图中的名字。

laravel 5.4表单在本地主机上不显示任何内容。并且它也没有显示任何错误消息。空白
