Why is the following code picking up data from inside the code itself rather getting input from user?
<?php
//register.php
include "./common_db.inc";
$link_id = db_connect();
mysql_select_db("sample_db");
$country_array = enum_options('usercountry', $link_id);
mysql_close($link_id);
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 $userid, $username, $usercountry, $useremail, $userprofile, $country_array;
global $PHP_SELF;
?>
