how to make the controller redirect results to an outside link or return a script alert in LARAVEL

hello I want to make a validation here in my table there is a column to store the data in the form of url to another link, here I want to make validation if the data exists then it will point to the link in $ get-> url_drive if it's not there then I want to display it in the form of a script for the user and redirect back this my controller

 $id = $request->input('id');
       $type = $request->input('type');
       $name = $request->input('name');
       $type = strtolower($type);
       $name = strtolower($name);
       $get = DB::table('users.user_connects')->where([
                                        ['user_id',$id],
                                        ['type',$type],
                                        ['name',$name]
        ])->first();
        if(isset($get)){
