                 echo mysql_error();
                if($queryresult)
                {
                    non_db_func::loginuser($email);
                    db_func::updatelogin($details_arr['lastlogin']);
                    return 1;
                    }

                else
                    return 0;
                    }
                     else{

                     return 2;    
                      }

can any one tell me ,why lastlogin column isnt updated in my db

Answer 1

The problem is that in function updatelogin($lastlogin) you have not defined what $email will hold.

IF you echo your query after your query update statement (after $query = UPDATE .....)

echo $query

you will see what your problem is.

Update 1

I think you should have something like this before $query statement
$email=$details_arr['email'];

OR

pass $email value in function as updatelogin($lastlogin, $email)
