Writing an email with line break only after fields with data

[tcady]

dmorison, thanks for helping me with that other question,it appears to be working great -
next question,
I want the email i get to only have a line break if there is data in a field I write to the email.

For example my form has many rows each with a quantity field...in the email I get, I want the results to be written each on a new line but only if the field had a value:

Item 1 Quantity=34
Item 4 Quantity=7
Item 9 Quanity=2

I am writing my email like this in the PHP file:
$message=
"$item1 $quantity1
$item2 $quantity2
$item3 $quantity3
$item4 $quantity4
$item5 $quantity5
etc" .

If I use a <BR> after each line it puts a break wehter there is data for $item/$quantty or not....thought the line is blank - how can I say if $item5!= nothing then add a <BR>
or is there anohther way?

are those the actual varnames?
how many are there total?

if so I have a thought ;)

[tcady]

yes they are the actual var names, there are 47 of each.
I'll be back to read your idea and implemnt it on Monday! thanks ahead of time.

perfect

$message = "";
$counter = 1;
while ($counter <= 47) {
if (!empty(${'quantity' . $counter})) $message .= ${'item' . $counter} . ' = ' . ${'quantity' . $counter} . '<br>';
$counter++;
}

I initialized the message var but wasn't sure if you used it hiogher up in the code or not.
