PHP Help with Forms

Question

Hey everyone -
I have a quote form on my website that I'd like to tweak a
bit. There are
some fields that have a drop-down box of "Yes" or "No" and
directly after
that it says, "If Yes, ..." So, no matter which option is
chosen, the user
still sees that even if it doesn't apply to them - which I'm
OKAY with for
the time being, but wish to implement it differently.
If the user selects "Yes" - I'd like the the field that says
the question I
*need* to ask the user if they choose "Yes." If they select
"No," than the
box is never shown. Sounds simple enough, right? Right ...
My concern is a). how to show this hide/don't hide
functionality, and b).
how to validate (require) the box being "shown" if they
choose "Yes" and to
NOT validate (require) if they choose "No."
I'm going to upload a .html file to my server that has the
full code for my
quote.php page in plain text, so someone can help me
implement this.
Quote source code:
http://www.avenuedesigners.com/tests/quote_source.html
I colored the big chunks of PHP code red, and the form blue
for ease.
I've tried something like this:
<?php
if ($_POST['havewebsite'] == "Yes") {
echo ('<p class="labelbold">If yes, What is the Domain
Name?</p>
<input name="currentdomain" type="text"
class="contactfield2 inputstyled"
id="currentdomain" value="<?php if
(isset($_POST[\'currentdomain\'])) echo
htmlentities($_POST[\'currentdomain\']);?>" tabindex="11"
/>');
?>
And run into two problems:
1. It only shows up when the page is submitted, and I'm
naturally assuming
this is because of the $_POST being in there. I need it to
display
immediately if they select "Yes."
2. It physically prints out: <?php if
(isset($_POST[\'currentdomain\']))
echo htmlentities($_POST[\'currentdomain\']);?> - as the
value of the
textfield instead of leaving it blank/printing the previously
entered text.
How can I fix these, guys? Thank you!

Answer 1

you can apply a show-hide layer behavior to the YES check box
(onClick="MM_ShowHideLayers...)
and have the inverse show;hide behavior applied toi the NO
checkbox.
Once you have a Layer on your page and have applied the
behavior, you change that Layer into a
regular div by the way, just leave the same id.
Then, for validating the question only if yes is selected:
<?php
if ($_POST['have_a_website'] == 'yes' &&
empty($_POST['question'])){
$error = TRUE;
?>
