[RESOLVED] get # in url

rikmoncur

Is it possible to detect the # in a url with php or is it clientside?

eg http://www.somesite.com/somepage.php#sublink

I'm trying to get the 'sublink' bit of the url.

Tried $SERVER['PHP_SELF']; and $SERVER['REQUEST_URI']; but no joy.

UPDATE: meh... had a look round and seems it is only accessable by javascript.

I would have thought that it would show up in REQUEST_URI on the initial page load. However, its all clientside if the user clicks on an anchor that just moves them around the page...

The "#..." part is never sent to the webserver; instead, client-side browsers strip it out and handle it accordingly once the page has loaded.

wouldnt $_SERVER['QUERY_STRING']; work or is that with a ? only

when i want to grab just the query string i do somthing like.

then say its a image from a link

<a href="view.php?bob_falls.jpg">Bob Falls</a>

the view page will contain

<?php
$url="http://".$SERVER['HTTP_HOST']."/images/".$SERVER['QUERY_STRING'];
?>

at the top and

in the body.

is that what you are trying to do?

bradgrafelman

Yes, $_SERVER['QUERY_STRING'] displays all data past the "?" in a URL, but once again, browsers don't even send the "#..." data to the webserver, so a PHP script has no chance at accessing it.

seems that even javascript can sometimes miss it too.

document.location.href

doesn't always work.

I'll mark this thread as resolved.

Coming back to this - what I was trying to do:

I have a navigation menu with links that change background colour to indicate which page you're on - eg if you're on the contact page, the contact page link will have a gray background.

<a href="contact.php" <?php if(basename($_SERVER['PHP_SELF']) == "contact.php") {echo "style='background-color:#ccc;' "; } ?> />contact</a>

If there's another link to 'feedback form' which is half way down the contact page
<a href="contact.php#feedback" />
then I need to detect that #feedback.

That was the problem.

This is the workaround:

Make the link submit a form:

<form action="contact.php#feedback" method="POST" name="form">
<input name="feeback" type="hidden" value="feedback" />
</form>
<a href="#" onclick="document.form.submit()"  >feedback form</a>

Instead of detecting #feedback I can now detect the $POST['feedback'] and use that to change the background colour of the link eg -

<a href="#" onclick="document.form.submit()" <?php if(isset($_POST['feedback'])){echo "style='background-color:#ccc;' "; } ?> / >feedback form</a>
