Copy values from one table to another

[vista]

Hi there.

Okay heres the scenario. I have 2 tables "Logins" and "User_Details"
What I want to do is write a PHP query that whenever a new user is created, that is manually entered into "User_details" table using a form, the next thing that should happen is that it should copy the value of the first 2 attributes from user_details table which are user_id and password into "Logins" table having the same 2 attributes only.

So what is the correct PHP query code for this. I tried many things but failed. I need somebody whos good at php / mysql to help me out! :)

Thanks!

I have everything setup. I just need the codes that do the copying. Assuming that the values entered are stored like this:

$values["user_id"]
$values["password"]

Attribute user_id is a primary key.
