One way that I would do it is break out of the print statement, and then
execute the if statement, print the appropriate menu, and then go back
into the heredoc.

Or you could execute a switch statement before hand, that handles the
$_POST variables, and then have a varaible of say $selectstatement set to
the appropriate select code that prints out in the heredoc.. so it would
be like

     I am submitting ...
     $selectstatement
     <br />

instead of that whole if statement.

Personally, I wouldn't use a heredoc for this purpose.  Instead, break =
out of PHP mode, like so...

function printForm()
{

global $errorMessage;

?>

<p>*denotes a required field.</p>

<form action=3D"<?=3D$_SERVER['PHP_SELF']?>" method=3D"post" =
enctype=3D"multipart/form-data">

....

<php

}

I always use this method outputting large amounts of text and it's =
worked very well, and with quite clean code.
