Form E-mail Submission

Question

Good evening to all, I need some help on a complex problem,
to me at least. I will have a form that has a great deal of text
boxes, radio buttons and check boxes. Only a few radio buttons
and/or check boxes will be selected each time someone fills out the
form. Is there a way to have it to where only what is filled out is
sent in the email submission and not all of the blank areas? There
are roughly 30 possible questions and sometimes someone may only
answer 10. I do not want 20 empty questions in between the 20 that
were answered. Any help would be appreciated. Thank you in advance.

That won't work for two reasons:
1. The conditional statement needs to be enclosed in
parentheses like this:
if (isset($_POST['your_radio_Button'])) {
$email_body .= $_POST['your_radio_button']
2. If nothing is selected for a radio button group or a
checkbox, it's
not included in the $_POST array anyway. However, empty text
fields,
text areas, and select drop-down menus are always included in
$_POST
array, even if nothing is inserted into them or selected.
A simple way to solve the OP's problem with PHP would be
something like
this:
<?php
if ($_POST) {
$email_body = '';
foreach ($_POST as $key => $value) {
$value = trim($value);
if (!empty($value)) {
$email_body .= "$key: $value\n";
?>
This assumes that none of the $_POST array elements is an
array (for
example, from a multiple select menu or checkbox group). It
also ignores
such issues as magic quotes and sanitizing user input. It
just provides
the bare bones of the answer to the original question about
how to
exclude empty fields.
