I'm not sure if this has been reviewed before, but I didn't see anything in the forum about it. I have a basic php submit form that I have customized per my needs for fields. Everything works perfectly however, I have a drop down menu with some selections. One of the selections, when clicked will display an additional field **only displays when clicked**, I need that field to be required to be filled out only when it is displayed/clicked. Can someone point me in the right direction? My php skills are very light to none. Thanks, I can post my code as well if that makes it easier. Thanks..

Here is the code:


<?
$editFormAction = $_SERVER['PHP_SELF'];
if (isset($_SERVER['QUERY_STRING'])) {
$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);
}

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {
$fromemail=$_POST['Email'];
$email = $HTTP_POST_VARS[Email];
$mailto = "--------@yahoo.com";
$mailsubj = "Contact Form";
$mailhead = "From: $fromemail";
reset ($HTTP_POST_VARS);
$mailbody = "Values submitted from web site form: General Contact Form - www.-------.pro/gen.php/ \n";
while (list ($key, $val) = each ($HTTP_POST_VARS)) { $mailbody .= "$key : $val\n\n"; }
if (!eregi("\n",$HTTP_POST_VARS[Email])) { mail($mailto, $mailsubj, $mailbody, $mailhead); }
echo "<span style='color:#666666'>Your message has been sent &amp; someone will contact you shortly. Thanks for choosing -----.</span>";
}
