Hi Andy -- I could really use your help with something...

I've got a Gallery app that I'm using and adding a dropshadow to on the fly, but at the beginning of each session, it appends a string of characters to end of the image path. Do you think you'd be able to help me filter it out?



Take a peek at this thread (or below) to see this problem:
http://gallery.menalto.com/node/40941

Code:
http://travelvice.com/support/alterimage.php?url=http://snapshots.travelvice.com/download/1495-8/thailand.jpg?g2_GALLERYSID=6d9ba394bdecb7fed172ff65f56e81ee


Thanks for the brain power Andy!

- Craig

OK, so if I understand it, you have a url posted to a webpage that looks like:

Code:
http://travelvice.com/support/alterimage.php?url=http://snapshots.travelvice.com/download/1495-8/thailand.jpg?g2_GALLERYSID=6d9ba394bdecb7fed172ff65f56e81ee


And given $_GET['url'], which looks like:

Code:
http://snapshots.travelvice.com/download/1495-8/thailand.jpg?g2_GALLERYSID=6d9ba394bdecb7fed172ff65f56e81ee


You want to be able to extract just the url not including the query string, right?

If so, that's easy!

PHP:
<?php $url = substr($_GET['url'], 0, strpos($_GET['url'], '?')); ?>

That's perfect Andy!

It turned into this on my end...

PHP:
<?php //check for (and remove) Gallery 2 session marker
        $g2pos = strpos($url, '?g2_GALLERYSID');
        if ($g2pos !== false) {
            $url = substr($url, 0, $g2pos);
        } ?>
