Makinng included strings in an email not appear if they're blank

[Maus]

That title is a little confusing I see, but here's hopefully a decent example:

If I have an email whose "body" part is the string:

$body = '$address1
$address2
$townorcity
$state
$zipcode
$country';

and the user has no need to complete, say, $towncity and $country and has therefore left them blank, how do I get it to not send something like:

52 Laketown Boulevard
blank line
Minneapolis
MN
54321
blank line

and instead send a much nicer version with the blank lines skipped?

edit: I am currently doing it with the mail() function, in case that's important

Just check each piece before you add it to the $body variable.

$body = "";
if ($address1)
$body .= '$address1';
if ($address2)
$body .= '$address2';

etc.......

Doy - it's so simple. Thanks very much, this is exactly what I needed. 🙂
