在formupload.blade.php中使用表单

@if(isset($success))
    <div class="alert alert-success"> {{$success}} </div>
@endif
    {!! Form::open(['action'=>'ImageController@store', 'files'=>true]) !!}

    <div class="form-group">
        {!! Form::label('title', 'Title:') !!}
        {!! Form::text('title', null, ['class'=>'form-control']) !!}
    </div>

    <div class="form-group">
        {!! Form::label('description', 'Description:') !!}
        {!! Form::textarea('description', null, ['class'=>'form-control', 'rows'=>5] ) !!}
    </div>

    <div class="form-group">
        {!! Form::label('image', 'Choose an image') !!}
        {!! Form::file('image') !!}
    </div>

    <div class="form-group">
        {!! Form::submit('Save', array( 'class'=>'btn btn-danger form-control' )) !!}
    </div>

    {!! Form::close() !!}
    <div class="alert-warning">
        @foreach( $errors->all() as $error )
           <br> {{ $error }}
        @endforeach
    </div>

</div>

Answer 1

把它放在composer.json中

"require": {
        "laravelcollective/html": "^5.4"
 },

要么

composer update 

然后在provider部分数组的config/app.php中添加它

composer require laravelcollective/html

之后,在别名数组的config/app.php中添加两个类别名

Collective\Html\HtmlServiceProvider::class,
