In a PHP code block, yes. And with error checking via isset() if your server requires that. Most are not that strict.

To diagnose the javascript part of it, I would need a link to the live page. However, even at that it would be time consuming to mock up because of the AJAX involved. To fix up the PHP part, I would need to see all of the PHP code employed.

And I only have a vague idea of you objective here. It would help if you could be more clear on that.

You might not need so much code. I get the feeling that you might be over complicating things. Like if you want to use AJAX, let it do most of the work and use less PHP and normal HTML. Or perhaps consider doing it all via PHP.

One thing I did say is that if the link doesn't fire (often the case where javascript is involved), it won't matter if the query string is valid or not, at least insofar as what would normally happen in PHP and HTML on the page.

This from my earlier post however does work:

PHP Code:

<?php 
if(isset($_GET['bob'])){ 
    echo $_GET['bob']; 
} 
?> 
<a href="?bob=Fred's Friend#/work/page1">GoTo /work/page1</a> 
<p>&nbsp;</p> 
<p>&nbsp;</p> 
<p>&nbsp;</p> 
<p>&nbsp;</p>

<p>&nbsp;</p> 
<p>&nbsp;</p> 
<p>&nbsp;</p> 
<p>&nbsp;</p> 
<p>&nbsp;</p> 
<p>&nbsp;</p> 
<p>&nbsp;</p> 
<p>&nbsp;</p> 
<p>&nbsp;</p> 
<a name="/work/page1">/work/page1</a>

and answers your original question.

I might add that if the javascript code relied upon an invalid query string in order to parse the link, of course it will no longer work if you change it to a valid one.

Another thing I didn't mention before because it's unclear to me what your $.ajax() function is doing is that it appears perhaps to be a POST request. If so, the query string (GET data), even if valid (perhaps especially if valid), might not get passed to the requested page.

thank you for all the communication, after all of this i think what i need is something like this
http://www.stoimen.com/blog/2009/04/...-url-with-php/

however this posts method doesnt seem to work, i will post files and if you have a moment, would be greatly appreciated

I have serious doubts about that method's applicability in this and pretty much any situation. You cannot call it via AJAX to get the value because the javascript on it cannot be used under an AJAX request, it requires a reload of the page so sort of defeats the purpose of doing anything unobtrusively, because it's using the hash, many requests to it will not be passed to the server anyway, and owing to its reliance upon cookies adds layers of uncertainty as to whether or not it will perform as expected.

That said, it doesn't work even as stated on the page because the code is written using invalid characters and is poorly thought out as well. If it would be of any help, here's a working version:

PHP Code:

---

<script type="text/javascript">
    (function(){
        var h = location.hash;
        h = h.substring(h.indexOf('#') + 1);
        document.cookie = 'anchor=' + h;
    <?php
        $c = isset($_COOKIE['anchor'])? $_COOKIE['anchor'] : '';
        $c = "'" . $c . "'";
    ?>
        if(h !== <?php echo $c; ?>){
            location.reload();
        }
    })();
</script>
<?php
    $c = isset($_COOKIE['anchor'])? $_COOKIE['anchor'] : '';
    echo $c;
?>

Perhaps if you ran it in a hidden iframe . . . But then there would be caching issues added to those already mentioned. These could perhaps be worked around, and then timing would become critical as to when this value became accessible to the rest of your code, still not solving many of the other issues.

But I would strongly advise you to use a GET request with a valid query string for this, it would be so much simpler.

thank you for all the help, will go over all the notes this evening.
