try to var_dump your $row and see if index u_name is exist

trace it where the null come from ?
the $result then check it, what if the $result is also wrong ?
that means the mysqli_query, then check your query is something wrong with them.
you can also look at mysqli_error() to see if there are any error when mysql executing your query
