从id检索用户信息

Question

I am working on a web app and am having trouble with a trivial issue. I have a table in a database, persons, which consists of the following fields: id, position (in company), username, firstname, lastname. I am working on an edit_user page. I have a main page listing the first+last names of all the users. I can then click on the names and this takes me to the edit_user page corresponding to that user. However, the updates that I make on the website do not get sent to the database (see code below).

//Inserting updates into database
        $query = "UPDATE person SET
            privilege  = '{$privilege}',
            nexus = '{$nexus}',
            firstname ='{$firstname}',
            lastname = '{$lastname}'"; 
        $query .="  WHERE id={$personid}";
        $result = mysql_query($query,$connection); 
        if (mysql_affected_rows() == 1) { 
            $message = "User was successfully updated"; 
        } else { 
            $message = "User was not updated";
            $message .= "<br/>" .mysql_error();
        }

My premonition is that something is wrong with the {$personid}, which was defined by:

function find_selected_user() {
    global $user;
    if (isset($_GET['personid'])) { 
        $personid = $_GET['personid'];
        return $personid
    } else {
        $user = NULL; 
    }
}

(the above function is supposed to return an array of $user's information) Please help -- I am so stuck! I am sure it is so simple but I've been thinking about it too long

You forgot the ending ; character here:

return $personid

Should be:

return $personid;
