You must use a redirect page specially if you want to use anchors in the same
page.
In your html pages:
<form method="post" action="redirect.php"
<fieldset>
<legend>Choose a Film</legend>
<label for="film">Title: </label>
<select name="film" id="film" onchange="this.form.submit();">
<option value="#"></option>
<option value="#">Fighting the Taliban</option>
<option value="#">Meeting the Taliban</option>
<option value="php/afghan.php">Afghan Ladies' Driving School</option>
</select>
<noscript><input type="submit" "value="GO" /></noscript>
</fieldset>
</form>
I assume the "this.form.submit()" works when the javascript is enabled, then
in theory you wouldn't need the submit button, so set it inside noscript tags
that should enable the button for none javascripters (may not work n old
browsers like mosaic).
--- redirect.php ---
<?PHP
switch($_REQUEST['film']) {
case 'taliban':
header('Location: http://www.example.net/pagename.html');
exit;
case 'driver':
header('Location: http://www.example.net/afghan.html');
exit;
case '#hello':
/* not sure if this works */
header('Location: http://www.example.net/afghan.html#hello');
exit;
default:
header('Location: http://www.example.net');
exit;
}
?>
--- eof ---
Using a redirect script makes you need only one server side script instead of
making all your pages to server side scripts.
