        if (Auth::check()) {
            $current_url = Session::get('current_url');
            $user = Auth::user();
            $industry = $request->input('industry');
            if (empty($industry)) {
                Session::flash('error', 'Industry is needed');
                return redirect()->back()->withInput();
            }
            $degrees = $request->input('degrees');
            if (empty($degrees)) {
                Session::flash('error', 'Degree is needed');
                return redirect()->back()->withInput();
            }
            $area_of_experiences = $request->input('area_of_experiences');
            if (empty($area_of_experiences)) {
                Session::flash('error', 'area of experiences is needed');
                return redirect()->back()->withInput();
            }

            $user_industry = UserIndustry::where('user_id', $user->id)->first();
            if (!empty($user_industry)) {
                $user_industry = $user_industry;
            } else {
                $user_industry = new UserIndustry();
            }

            $user_degrees_exists = UserDegree::where('user_id', $user->id)->get();
            if (!empty($user_degrees_exists)) {
                foreach ($user_degrees_exists as $user_degree_exist) {
                    UserDegree::destroy($user_degree_exist->id);
                }
            }

            $user_area_of_experiences_exists = UserAreaOfExperience::where('user_id', $user->id)->get();

                foreach ($user_area_of_experiences_exists as $user_area_of_experience_exist) {
                    UserAreaOfExperience::destroy($user_area_of_experience_exist->id);
                }
            }

            $user_industry->user_id = $user->id;
            $user_industry->industry_id = $industry;
            $user_industry->save();

            if (!empty($degrees)) {
                foreach ($degrees as $degree) {
                    $user_degrees = new UserDegree();
                    $user_degrees->user_id = $user->id;
                    $user_degrees->degree_id = $degree;
                    $user_degrees->save();
                }
            }
