First, let me say kudos on the subject matter of that site. Very noble
cause indeed. Second, let me be sure I am clear on what you are looking
to do. Someone comes to the site, chooses 1-9 on your membership page and
you would like to have it fill in the "Amount Enclosed" text box
automatically based on what they select?

If so, it is possible but you won't use PHP. PHP is a server side script
and what you are looking to do is client side. You'll need some
Javascript - more specifically the "onchange" javascript event.

Looking at your code it seems you are using a code generating app, like
FrontPage, and I have no idea if an example from me would break that code
or not, since I have never used one of those applications, so I won't try
it. But the "onChange" javascript function is what you need.

HTH,

thanks for your reply and your comment, I asked because I had been given
the following information to the question in another group



Yes, simply make the form page a php e.g. memapp.php and set the action
to
self
e.g.
echo " <form method=\"post\" action=\"$PhP_SELF\">\n";

By passing any variables back to itself via the form call you can then
get
parse the variables and return the result in the shape of the completed
form
with the amount (totaled) etc.

Thanks Ian,

Could you possibly point me in the direction of more info on this or
somewhere I can get a script, as I have not yet started on php.

Gerald,

Have a look on http://www.php.net/ _the_ best reference you'll find
=)

I'll explain my point to clarify anyway:


$PHP_SELF was / is fine if register_globals are enabled.. but this
opens up security concerns as no checks are done to see if the data
has come from say, a GET URL (foo.com?bar=bleh) or if from a POST
method in a form.. or from a cookie, session var etc etc, so as you
can see, this is somewhat insecure (or could be). Defining it as
$_SERVER['PHP_SELF'] means that if I used foo.com?bar=php_self it'd
fail, as that would only be available from $_GET['php_self'].

You can find more indepth explanations on this again, on php.net is
you doa search for "register_globals" and check out the security
comments etc about it =)

Also.. create a .php file with just:


<?php phpinfo(); ?>


Access it via a URL as you would normally, and it'll display a load
of info regarding the server and PHP install. If you scroll down to
the bottom of the page, you'll see lots more $_SERVER[] vars too, to
which you can use in scripts too. As phpinfo() displays the output of
such vars, you can see as to what each would contain too, to help you
know of that's the one you want to use etc etc etc.


HTH.



Regards,

Ian

Thanks again, only a month ago I did not have access to php on the host
but thanks to someone donating hosting to us I have found there are lots
of things I can use. By the way before I started the site for Animals in
Distress I didn't know anything about html.
