In case this has yet to be answered to your satisfaction...
Your page will *have* to reload when the user presses the button, but
the majority of content can look the same, except for the content you
want to change.
Let's say you've named the button "section" and its value is "home" as
in:
<input type="text" name="section" value="home"/>
When the user presses the button, the form now shows the value of
"section" as "home". PHP knows this has occurred. So you can make any
action occur by simply (in PHP):
if ($_POST['section'] == 'home') {
do_something();
}
In your case, you want a section of your HTML page to display something
else. So, wherever you want that content to be displayed in your HTML
page, do this:
<?php
if ($_POST['section'] == 'home') {
echo "a bunch of text for home stuff";
}
?>
The "<?php" thingie tells Apache to interpret the next part as PHP, and
the "?>" part tells Apache that the PHP part is over. If you're using
GET instead of POST for the form then change "$_POST" above to "$_GET".
Every item in a form yields a POST or GET variable which PHP can read,
just as it did above.
There are alternate ways to do this, but the above is probably the
simplest for you.
I recommend "Programming PHP" an O'Reilly book as a reference for the
language.
