Those are the php files that I query two variables to the database.

die.php

<?php

include('common_db.php');

$btn = $_GET['var1'];

$loc = $_GET['var2'];


$result = mysql_do("INSERT INTO tes2 (button_id, location_id) VALUES ('$btn','$loc');");
// $result = mysql_do("INSERT INTO tes2 (test) VALUES ('$btn');");

echo $result;

?>

//common_db.inc

<?php
//common_db.inc

$dbhost = 'xxx.113.xxx.xxx';
$dbusername = 'ilteris';
$dbuserpassword = 'xxxxxx';
$default_dbname = 'moodbox';

$MYSQL_ERRNO = '';
$MYSQL_ERROR = '';

function db_connect() {
	global $dbhost, $dbusername, $dbuserpassword, $default_dbname;
	global $MYSQL_ERRNO, $MYSQL_ERROR;
	
	$link_id = mysql_connect($dbhost, $dbusername, $dbuserpassword);
	if(!$link_id) {
		$MYSQL_ERRNO = 0;
		$MYSQL_ERROR = "Connection failed to the host $dbhost.";
		return 0;
	}
	else if(empty($dbname) && !mysql_select_db($default_dbname)) {
		// MYSQL_ERRNO = mysql_errno();
		// MYSQL_ERROR = mysql_error();
		return 0;
	}
	else return $link_id;
}

function sql_error() {
	global $MYSQL_ERRNO, $MYSQL_ERROR;
	
	if(empty($MYSQL_ERROR)) {
		$MYSQL_ERRNO = mysql_errno();
		$MYSQL_ERROR = mysql_error();
	}
	return "$MYSQL_ERRNO: $MYSQL_ERROR";
}

function mysql_do($sql) {
	$link_id = db_connect();
	$result = mysql_query($sql, $link_id);
	return $result;
}

?>
