Question

When wanting to update field completed_status by one when this form is submitted, it is staying at 0. The query $submission is the update for the users tables.
This is the code I have been using:

$user_id = intval($_SESSION['user_id']);
if (isset($_POST['doPersonal'])) {

    if (empty($err)) {

        $Sex = mysql_real_escape_string($_POST['Sex']);
        $Second_Nationality = mysql_real_escape_string($_POST['Second_Nationality']);
        $Birth_Place = mysql_real_escape_string($_POST['Birth_Place']);
        $Birth_Country = mysql_real_escape_string($_POST['Birth_Country']);
        $children = mysql_real_escape_string($_POST['children']);

        $the_query =   "INSERT INTO personal (user_id, Sex, Second_Nationality, 
Birth_Place, Birth_Country, children)
VALUES ('$user_id', '$Sex', '$Second_Nationality','$Birth_Place', '$Birth_Country',
'$children')
ON DUPLICATE KEY UPDATE Sex=VALUES(Sex), Second_Nationality=VALUES(Second_Nationality),
Birth_Place=VALUES(Birth_Place) , children=VALUES(children)";



        // query is ok?
        if (mysql_query($the_query, $link) ){

            // redirect to user profile
            header('Location: myaccount.php?id=' . $user_id);

            $submission= "update users set completed_status=completed_status+1 where 
id='$_SESSION[user_id]'";
        }
    }
}

}

From the above code we can see that you are redirecting the page before the update query so please modify it as,

if (mysql_query($the_query, $link) ){

           $submission= "update users set completed_status=completed_status+1 where 
id='$_SESSION[user_id]'";

           mysql_query($submission,$link);  // to execute the update query              

          // redirect to user profile
          header('Location: myaccount.php?id=' . $user_id);


}
