Laravel5.8入门与实战-安全与优化

表单验证提示信息

 　　　　if ($result===true || $result>0) {             $request->session()->flash('data',['class'=>'success','msg'=>'更新成功']);         }else{             $request->session()->flash('data',['class'=>'danger','msg'=>'更新失败']);         }         return redirect(route('admin.config.siteconfig'));     }

表单验证blade里面

   　　　　　　@if (session()->has('data'))                   <div class="alert alert-{{session('data')['class']}}">                     {{session('data')['msg']}}                   </div>               @endif  

数据验证

private function checkdata($name='siteconfig',$request){         switch($name){             case 'infomation':                 $datavalidate = $request->validate([                     'company'=>'required',                     'address'=>'required',                     'phone'=>'required',                 ],[                     'company.required'=>'公司名称不能为空',                     'address.required'=>'地址不能为空',                     'phone.required'=>'客服热线不能为空',
                ]);                    break;             case 'baidu':                 $datavalidate = $request->validate([                     'key'=>'required',                 ],[                     'key.required'=>'百度密钥不能为空',                 ]);                    break;             default:                 $datavalidate = $request->validate([                     'name'=>'required',                     'tittle'=>'required',                     'sitetittle'=>'required',                     'domain'=>'required|url',                 ],[                     'name.required'=>'配置标识不能为空',                     'tittle.required'=>'配置名称不能为空',                     'sitetittle.required'=>'网站名称不能为空',                     'domain.required'=>'网站域名不能为空',                     'domain.url'=>'网址输入不正确',                 ]);                    break;

 

//根据配置标识获取配置信息

    private function getconfig($name = 'siteconfig'){         $res_config = DB::table('config')->where('name','=',$name)->first();         $config = [];         if ($res_config){             # code...             $config = json_decode($res_config->config,true);         }         return $config;     }         }

后台设置信息设置完成后跳转到当前设置页面

   return redirect(route('admin.config.'.$request->name));  

使用pjax实现网站后台页面部分刷新

命令composer require spatie/laravel-pjax

 kernel.php添加中间件

protected $middleware = [         \App\Http\Middleware\CheckForMaintenanceMode::class,         \Illuminate\Foundation\Http\Middleware\ValidatePostSize::class,         \App\Http\Middleware\TrimStrings::class,         \Illuminate\Foundation\Http\Middleware\ConvertEmptyStringsToNull::class,         \App\Http\Middleware\TrustProxies::class,         \Spatie\Pjax\Middleware\FilterIfPjax::class
