    Hi everybody,

    Who can help me to fix a problem.

    I want to join two tables.

    Aid int; //auto increment
    name varchar;

    Bid int; //same id as Aid
    Author varchar;

    if ($voegtoe) { // name of button in form

    //add a record ID Aid auto increment

    $sql_A = "INSERT INTO TABLE_A (naam) VALUES

    //Tryin' to get the last ID from TABLE_A
    $result_A = mysql_query("SELECT Aid FROM TABLE_A");

    $objectid= mysql_query($result_A);

    //Tryin' to use Aid From TABLE_A

    $sql_B = "INSERT INTO TABEL B (Bid, author) VALUES
    ('$objectid', '$author')";


    TABLE_B is not getting the ID from TABLE_A, Why??

    Because you are not getting the last id from table a. Your select will return the first id (actually it returns all but you're only getting the result for the first one.) There's a easier, safer way to do this. Check the php manual for the function mysql_insert_id(). This will do what you want.
