Sort members on registration using gender

[***Teh GodFather***]

Hi,
I have set that setting gender on registration si required...
Now I want that, when a new member is registered to be sorted in one of two membergroups depending on his gender...
I supose that I need to edit Register.php but I dont know how...
Can anyone help me?

I think i will have to use this code:

Code Select Expand

// No gender specified...
if (empty($user_settings['gender']))
$user_info['groups'][] = 10;
          // User is male..
elseif ($user_settings['gender'] == 1)
$user_info['groups'][] = 11;
// User is female...
else
$user_info['groups'][] = 12;

to check gender... But this code wont sort them... Then i want to check if they are allready sorted... I suppose that this query will use but i am not sure...

Code Select Expand

$group = db_query (SELECT `ID_GROUP`
FROM `members`
WHERE `ID_MEMBER` = $member_id);



Now i am not very goog with php so if someone could help me with coding...

It should look like this:

if $group="" INSERT into members group id where id_member=$member_id;

And then to set group id based on gender..
