insert related fields

Hi,

Quick simple question

I am try to insert my form fields into 2 related tables.

Currently I am using this query:

$query = "INSERT INTO contacts (id, last_name, first_name, phone_mobile, assigned_user_id) VALUES ('{$id}', '{$lastname}', '{$firstname}', '{$telephone}', '{$user}')";

The problem is I also want to insert fields $social ; $address, etc

These fields are located in a separate table "contacts_cstm"

The common related key is "id"

How do I correctly construct the query?

THanks in advance.

 

change the table with phpmyadmin.

and add the new cell names in the ('names','names1') part and {$social} and {$address} at the other places!
