如果条件失败，Laravel会从模型抛出错误

I am doing all the validations in ModelMy Rule is public static $rules = array( 'VehicleNumber' => 'required|unique:vehicle', 'NumberSeats' => 'required', 'VehicleType' => 'required', 'MaximumAllowed' => 'numeric|max:3', 'VehicleCode' => 'required|unique:vehicle');}But for changing the file name and checking its size i am handling in a SetFooAttributepublic function setInsurancePhotoAttribute($InsurancePhoto){ if($InsurancePhoto && Input::file('InsurancePhoto')->getSize() < '1000') { $this->attributes['InsurancePhoto'] = Input::get('VehicleCode') . '-InsurancePhoto.' . Input::file('InsurancePhoto')->getClientOriginalExtension(); Input::file('InsurancePhoto')->move('assets/uploads/vehicle/', Input::get('VehicleCode') . '-InsurancePhoto.' . Input::file('InsurancePhoto')->getClientOriginalExtension()); }}There in the Conditionif($InsurancePhoto && Input::file('InsurancePhoto')->getSize() < '1000')If it fails the Storing of Image, Setting Attribute won't be done.But How can i throw the Error to the User in this Case ? 解决方案 getSize() return integer so you should not use string for comparison as you have written 1000 in single quotes. You can create your own custom Validation in laravel.
