Set your form up something like this (using mypage.php as your page).

<form method='get' action='mypage.php'>
<select name='view'>
<option value='view1'>View 1</option>
<option value='view2'>View 2</option>
</select>
<input type='submit' value='Change'>
</form>

Then when you change the view and click on submit, it refreshes the page with with the variable 'view' passed on the URL, along with its value. Then use PHP's $_GET[''] function to get the variable's value for processing...

<?php
if (!isset($_POST['submit']))
{
	echo '
	<form action="" method="POST">
	choose form:<br>
	<select name="form" size="2">
	<option value="1">form #1
	<option value="2">form #2
	</select><br>
	<input type="submit" name="submit" value="submit">
	</form>
	';
}
else
{
	if (isset($_POST['form']))
	{
		echo '
		you chose form #' . $_POST['form'] . '<br><br>
		<form action="" method="POST">
		';

	if ($_POST['form'] == 1)
	{
		echo '
		these are the fields for form #1:<br>
		field #1 <input type="text" name="field1"><br>
		field #2 <input type="text" name="field2"><br>
		field #3 <input type="text" name="field3"><br>			
		';
	}

	if ($_POST['form'] == 2)
	{
		echo '
		these are the fields for form #2:<br>
		field #1 <input type="text" name="field1"><br>
		field #2 <input type="text" name="field2"><br>
		field #3 <input type="text" name="field3"><br>			
		';
	}

	echo '
	<input type="submit" name="submit" value="submit">
	</form>
	';

}
else
{
	echo 'you did not choose a form';
}
}
?>
