### laravel 自带的上传功能 ###

1.文件上传配置  
项目目录下面config->filesystems.php，其中有一个disk的配置。

添加一个自定义的驱动 `public`,设置文件上传路径，这里设置为storage目录下面的app文件夹:

2.模板页面

{!! Form::open(['route' => 'order.store', 'class'=>'form-horizontal mt-20', 'enctype' => 'multipart/form-data']) !!}
    <div class="form-group">
        <label class="col-sm-2 control-label label-width">图片：</label>
        <div class="col-sm-10">
            <input type="file" name="picture" id="picture" required="true">
        </div>
    </div>
    <div class="form-group">
        <label class="col-sm-2 control-label label-width"></label>
        <div class="col-sm-10 mb-15">
            <button type="submit" class="btn btn-primary">提交</button>
        </div>
    </div>
    {!! Form::close() !!}

2.在OrderController控制器里面

使用命名空间

use App\Models\Order;
    use Illuminate\Support\Facades\Storage;

store 方法中对上传文件进行处理

public functiuon store(REQUEST $request) 
    {
        $data = $request->all();
        $picture = $request->file('picture'); 
    
        if ($picture->isValid()) {
           $ext = $picture->getClientOriginalExtension();
           $path = $picture->getRealPath(); 
           $filename = 'data/upload/'.time().mt_rand(999, 9999).'.'.$ext; //文件路径，存入数据库
           Storage::disk('public')->put($filename, file_get_contents($path));
        }
        $data['picture'] = $filename;
        Order::create($data);
    }
