The code below can't call the create_account function when submit button is clicked. What is actually wrong with the form?
<?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);
