I have an input form with 7 drop downs pairs (Item/Item Colour).

I want to loop through to check if they are empty ($_POST['items1'], $_POST['items2'].... $_POST['items7']).. same thing for item colour.

I wanted to loop through, assign my loop variable to a variable with text
$item_val = "items".$i;
then check if $_POST['$item_val'] is empty.  I have tried ${$item_val}, nothing seems to work.

Is there anyway to achieve this?

Thanks

$_POST[$item_val] not $_POST['$item_val']
