<a href="<? echo $PHP_SELF,'?','&action=something' ?>">do somehthing</a> this seems to work but can someone explain the syntax to me what does a '?' and a ',' do in PHP? I thought you joined strings with a full stop '.' (a period if you are from the US).

You are passing multiple parameters to the 'echo' language construct. The '?' is just a string, and is interpreted just like any other string in PHP. That will print out the value of $PHP_SELF followed by ?&action=something By the way, you really shouldn't have register_globals turned on. And you also really shouldn't top-post. -- Jasper Bryant-Greene Freelance web developer http://jasper.bryant-greene.name/ If you find my advice useful, please consider donating to a poor student!
