I do this internally on our systems all the time and don't generally
have issues. The only fields that are posted to a page are the ones that
are inside of the <form> tag that has the button that was pressed.

Using the example XHTML code:

~  <form method="post" action="test.php">
~    <input type="text" name="foo" />
~    <input type="submit" value="Button 1" />
~  </form>

~  <form method="post" action="test.php">
~    <input type="text" name="bar" />
~    <input type="submit" value="Button 2" />
~  </form>

If a user clicks on Button 2, then only the text field "bar" is posted
to bar.php -- "foo" is ignored.

$HTTP_POST_VARS is deprecated as of PHP4 -- avoid it like the plague, if
you can.

| buttons.

It's really hard to tell what you're trying to do without seeing both
PHP code and accompanying HTML, so I can't comment on this one.

You can try several other methods. Try these:

~  1. echo "<pre>". print_r($_POST) ."</pre>";
~  2. echo "<pre>". var_dump($_POST) ."</pre>";
~  3. foreach ($_POST AS $key => $val) { echo "$key => $val<br />" }

Note that if you're using PHP3 instead of PHP4, you'll need to replace
$_POST with $HTTP_POST_VARS instead.
