ถามหน่อยค่ะ insert ข้อมูลลง database ได้ แต่ไม่มีข้อมูล

$host = "localhost:3306";
$username = "dbpapor";
$password = "qwerty";
$objConnect = mysql_connect($localhost,$username,$password);

$objDB = mysql_select_db("papor_net");

		$strSQL = "INSERT INTO `member`(`username`,`password`,`name`,`lname`) VALUES ('".$_POST['username']."', 
		'".$_POST["password"]."','".$_POST["name"]."','".$_POST["lname"]."')";
		$objQuery = mysql_query($strSQL);
		
		echo "Register Completed!<br>";		
	
		echo "<br> Go to <a href='login.php'>Login page</a>";		
	

mysql_close($objConnect);
