Laravel Blade将空值返回给控制器

Question

*问题已回答*

我试图让表单文本字段输入从刀片到控制器变量的值，然后传入db查询但它给我空值。

例如，$ a = request（'chargeable_price'）;

这给了我空值。有人能帮我吗？代码运行没有错误但数据库字段更新为零而没有传递值。

这是我的控制器代码

public function postEditSubscription(Request $request, $property_id, $subscription_id){


        try {

            $a = request('chargeable_price');

            DB::table('subscriptions')->where('id',$subscription_id)->update(array(
                'price'=>$a,
            ));


        }catch(ModelNotFoundException $e){

            throw $e;

        }catch(ModelValidationException $e){


            throw $e;

        }catch(IntegrityException $e){

            throw $e;

        }catch(Exception $e){


            throw $e;

        }

      //  $request->flush();

        return redirect()->route('admin::managing::subscription::index', array('property_id' =>$property_id))->with(Sess::getKey('success'), Translator::transSmart('app.You have successfully edit Subscription Details.', 'You have successfully edit Subscription Details.'));


    }

这是我的刀片代码

Answer 1

阅读你的截图，你的答案是

• $request['subscriptions']['chargeable_price'];或，
• request('subscriptions.chargeable_price')

完全取决于你使用哪一个。

Answer 2

尝试访问像这样的字段$ a = $ request-> input（'chargeable_price'）;
