In the first form include a hidden field that identifies the form when
you are checking the post values after submission. This way you know
exactly what form was submitted. Second if the first form has been
submitted then you know that you need to present the second form also.
THe second form should also have a hidden field so that it may be
identified upon submission. In this way you can detect which form was
submitted (submit buttons are problematic for determining which form was
submitted). Then when you detect that the second form was submitted you
can handle it's data as you please and then only present the first form.
A basic example follows (completely unchecked for typos/errors):
<?php
$submittedForm = null;
if( isset( $_POST['formSubmitted'] ) )
{
$submittedForm = $_POST['formSubmitted'];
if( $_POST['formSubmitted'] == 'form1' )
{
// do something with its data.
}
else
if( $_POST['formSubmitted'] == 'form2' )
{
// do something with its data.
}
}
?>
<form name="form1" method="post" action="<?= $_SERVER['PHP_SELF'] ?>">
<input type="hidden" value="form1" />
<select name="game">
<option value="1">1</option>
<option value="2">2</option>
<option value="3">3</option>
<option value="...">...</option>
</select>
<input type="submit" name="continue" value="Continue" />
</form>
<?php
if( $submittedForm == 'form1' )
{
?>
<form name="form2" method="post" action="<?= $_SERVER['PHP_SELF'] ?>">
<input type="hidden" value="form2" />
<select name="blah">
<option value="foo">Foo</option>
<option value="fee">Fee</option>
<option value="fii">Fii</option>
<option value="foh">Foh</option>
<option value="fum">Fum</option>
</select>
<input type="submit" name="continue" value="Continue" />
</form>
<?php
}
?>
Cheers,
Rob.
