I have been trying without good result to run the source code for 'register_form.php' in 'Beginning PHP5' to create a user registration interface.

Please someone to give me the correct complete source code.

Note: This code below in BegPHP5Code is also incomplete. The Create_account function cannot be switch unto.

Here is the code
<?php
//register.php
include_once "./common_db.inc";

function in_use($userid) {
   global $user_tablename;

   $query = "SELECT userid FROM $user_tablename WHERE userid = '$userid'";
   $result = mysql_query($query);
   if(!mysql_num_rows($result)) return 0;
   else return 1;
}

function register_form() {
global $userposition;
global $PHP_SELF;

$link_id = db_connect();
mysql_select_db("sample_db");
$position_array = enum_options('userposition', $link_id);
mysql_close($link_id);

?>
