สอบถามเรื่อง การใช้ if เช็คค่า file รูปภาพที่ส่งมาครับ

if($_FILES["filUpload"]["tmp_name"]==""){
		$strSQL = "INSERT INTO payment_customer(Order_ID,Customer_ID,Bank_ID,Date_Pay,Time_Pay,Amount_Pay) 
		VALUES ('".$_POST["OrderID"]."','".$_SESSION['Customer_ID']."','".$_POST["Bank_ID"]."','".$_POST["Date_Pay"]."',
		'".$_POST["Time_Pay"]."','".$_POST["Amount_Pay"]."')";
		$objQuery = mysql_query($strSQL);
		
		$strSQL = "UPDATE orders SET Status = '2' WHERE OrderID = '".trim($_POST['OrderID'])."' ";
		$objQuery = mysql_query($strSQL);
		
		$strSQL = "UPDATE orders_detail SET Status = '2' WHERE OrderID = '".trim($_POST['OrderID'])."' ";
		$objQuery = mysql_query($strSQL);
			
	echo "<script>alert('เเจ้งชำระเงิน เรียบร้อยเเล้ว')</script>";?>
	<script type="text/javascript">
	window.location="page_member_order_history.php";
</script><?
		}
	elseif(move_uploaded_file($_FILES["filUpload"]["tmp_name"],"myfile/image_memberpayment/".$_FILES["filUpload"]["name"]))
