Frage zu Insert into

Hi,

habe hier ein Regsitrierungsformular, dieses möchte ich mit einem weiter Feld "PCNAME" erweitern.

Soll heissen, der User muss seinen PC-Namen eingeben, wenn er sich regsitriert. Die Tabelle "users" gibt es, darunter habe ich bereits ein Feld "pcname" angelegt. Das auslesen funktioniert nur das eintragen nicht.

bei insert into muss ich den Feldnamen eingeben und das value, verstehe dies aber hier nicht. Warum steht hier NULL, ist doch garkein Feld ."values(NULL,".. Und was macht eigentlich die NULL hier drin: $HTTP_POST_VARS[email]', NULL, '$password', ???

Hoffe jemand kann das Script einfügen...

Hier das Skript:

<?php

require_once "common/style.php";

if(isset($register)){

    if($HTTP_POST_VARS[user] == ''){
        printerror("$lang_usernotblank");
        exit;
    }

    //check username first
    $sql = "SELECT user_name from $mysql_users_table where user_name='$user'";
    $result = $db->query($sql);
    $numrows = $db->num_rows($result);

    if($numrows > 0){
        printerror($lang_usernametaken);
        exit;
    }

    //check passwords
    if($HTTP_POST_VARS[password] != $HTTP_POST_VARS[password2]){
        printerror($lang_passwordsnotmatch);
        exit;
    }
    else{
        $password = md5($HTTP_POST_VARS[password]);
    }

    //create user account, but do not activate it.
        $sql = "INSERT into $mysql_users_table values(NULL, '$HTTP_POST_VARS[first]', '$HTTP_POST_VARS[last]', '$HTTP_POST_VARS[user]', '$HTTP_POST_VARS[email]', NULL, '$password', '$HTTP_POST_VARS[office]', '$HTTP_POST_VARS[phone]', '$HTTP_POST_VARS[pcname]' 0, 0, 0,'default', NULL, NULL, NULL, 0, NULL, '$default_language', 0)";
    $db->query($sql);
    $uid = $db->insert_id();

    //send notification to admin for approval
    $sql = "SELECT template from $mysql_templates_table where name='email_new_user'";
    $result = $db->query($sql);
    $template = $db->fetch_array($result);
    $template=str_replace("'","'",$template[0]);
    eval("\$email_msg = \"$template\";");

    if($enable_smtp == 'lin'){
        sendmail($admin_email, $helpdesk_name, $HTTP_POST_VARS[email], $uid, $email_msg);
    }
    if($enable_smtp == 'win'){
        mail($admin_email, "$lang_registerforaccount", $email_msg, "From: ".$helpdesk_name ."<".$HTTP_POST_VARS[email].">\nReply-To: ".$HTTP_POST_VARS[email]."\n");
    }
    //no other options...if enable_smtp is set to anything else, the email will not get sent.
    
    //print out the message so the user knows he/she is awaiting approval
    echo "$lang_messagetoadmin
";
    exit;
}

echo "<form method=post>";

startTable("$lang_register", "left", 80, 1);
    echo "<tr><td class=back>
";


        startTable("$lang_register - $lang_required", "left", 80, 2);
            echo "<tr><td width=27% class=back2>$lang_username: </td>
                <td class=back> <input type=text size=30 name=user></td></tr>\n";

        endTable();

    echo "<div align=\"center\"><input type=submit name=register value='$lang_register'></div>";
    echo "</form>";
    echo "</td></tr>";

endTable();
