Why no [fragment] in parse_url($_SER VER['PHP_SELF'])?

[deko]

I'm trying to identify which named anchor is currently being viewed on a
page. Although the address bar of my browser shows #whatever appended to
the end of the url, I can't seem to find it in a variable.

My efforts below return no value for ANYTHING except [path]. Am I missing
something?

$url = parse_url($_SER VER['PHP_SELF']);

$scheme = ($url[scheme]);
$host = ($url[host]);
$port = ($url[port]);
$user = ($url[user]);
$pass = ($url[pass]);
$path = ($url[path]);
$anchor = ($url[fragment]);

echo $scheme." = scheme<br>";
echo $host." = host<br>";
echo $port." = port<br>";
echo $user." = user<br>";
echo $pass." = pass<br>";
echo $path." = path<br>";
echo $anchor." = anchor<br>";

You will not be able to retrieve anchor with a $_SERVER variable since it isn't
transmitted to the server but handled on the client.

Hi and thanks for the reply.

I was reading up on anchors at
http://www.w3.org/TR/REC-html40/stru....html#h-12.1.2
The section: "12.2.3 Anchors with the id attribute" talks about using id's -
The id attribute can act as more than just an anchor name (e.g., style sheet
selector, processing identifier, etc.).

Do you think I can identify what is being viewed on the page if I use the id
attribute in the link? Other options?

*** this goes in page which I am linking to:
<a id="test"></a>

*** this is on page I am linking from:
<p><a href="tech.php# test">test</a></p>

The problem may still be client-side (as opposed to server-side) processing.
Perhaps Javascript is the way to go? If I could find some examples...

If the url http://www.domain.com/pagename.html#whatever the #whatever part
is not transmitted to the server. You'll need to deal with it on the client
side using Javascript.

10-4. That's what I am discovering. The goal here is to do different
things based on what section of the page is being viewed. Here's an
interesting article about using id's instead of names in anchors:
http://www.netmechanic.com/news/vol7/html_no6.htm

I've looked into Javascript a bit - but the question remains: how to
identify what anchor is currently beig viewed? If I can't do it in PHP how
to do it in Javascript?

Probably best to ask the Javascript group if you haven't already -
comp.lang.javas cript

try this:

<script language="javas cript">
var a = (window.locatio n.href.split('# ')) ;
document.write( a[1])
</script>

thanks for the question!

of course, this doesn't strictly tell you which anchor is currently
being viewed, only which anchor was requested.

as far as i can see there is no window or document property
corresponding to the idea of 'last requested anchor' or 'live anchor' or
whatever.

But using deko's idea of using ids (eg <a id="foo" name="foo"></a>) you can
now do:

<script language="javas cript">
var a = (window.locatio n.href.split('# ')) ;
document.getEle mentById(a). <-- other stuff here
</script>

You could use it to alter the style or content of the element or surrounding
element.
