I have a page with thumbnail pictures that can be clicked on to see a larger picture. Each picture is hyperlinked as follows <a HREF="show_pic.php?pic=blah&caption=Some+Text"> I access the 'pic' & 'caption' attributes with $_GET['pic'], etc. Pretty standard stuff. I have PHP set up so that error messages get mailed to a specified mail account. Every so often I get the following error message: Undefined index: caption In file /home/..../show_pic.php, line 64 page: /show_pic.php?pic=gb3.jpg&caption=Some+Text The problem is obviously (I think) that the $_GET['caption'] is failing. What I can't figure out is why the '&' got turned into '&'. Is a browser doing this?Yes it is. Actually, you should specify the URL with the & yourself, like this: <a HREF="show_pic.php?pic=blah&caption=Some+Text"> otherwise it is not valid HTML. -- ------------------------------------------------------------------------- Derick Rethans http://derickrethans.nl/ PHP Magazine - PHP Magazine for Professionals http://php-mag.net/ -------------------------------------------------------------------------
