laravel文件上传

一、视图文件代码

 <td>
        <input type="file" name="brand_logo" id="logo" size="45">
        <br>
        <span class="notice-span" style="display:block" id="warn_brandlogo">
          请上传图片，做为品牌的LOGO！
        </span>
 </td>

二、控制器代码

use IlluminateSupportFacadesStorage;

use IlluminateHttpRequest；

use IlluminateSupportFacadesDB;

public function add(Request $request)
    {
        if($request->isMethod('POST'))
        {
            $data = $request->all();
            $brand_logo = $request->file('brand_logo');
            if($brand_logo->isValid())
            {
                $ext = $brand_logo->getClientOriginalExtension();//后缀
                $path = $brand_logo->getRealPath();//路径
                $filename = date('Y-m-d-H-i-s').'.'.$ext;//重命名
                Storage::disk('upload')->put($filename, file_get_contents($path));//上传
            }
            $data['brand_logo'] = '/laravel56/public/brandpic/'.$filename;
            $res = DB::table('brand')->insert([
                'brand_name'=>$data['brand_name'],
                'brand_logo'=>$data['brand_logo'],
                'brand_desc'=>$data['brand_desc'],
                'site_url'=>$data['site_url'],
                'sort'=>$data['sort'],
                'is_show'=>$data['is_show']
            ]);
            if($res)
            {
                return redirect('Admin/Brand/brand_list');
            }
        }
    }

切记在config/filesystems.php中添加如下代码：

'upload' => [
            'driver' => 'local',
            'root' => public_path('brandpic'),//brandpic是自己定义的文件保存目录
        ],
