[Resolved] Capturing a URL

[Reformed]

Can anyone suggest good way of capturing a full url, so it could be assigned to variable? I have an update function that updates a record and I want my user to be returned to the same page they edited on after the changes where made, but I don't know what page they will be on.

yeah i do exactly the same thing on my site

the code i use is as follows

<?PHP
	$return = $_SERVER['PHP_SELF'];
	if($_SERVER['QUERY_STRING'] != ""){
		$return .= echo "?";
		$return .= echo $_SERVER['QUERY_STRING'];
	}
?>

this creates a var called $return, which is the current page. If any environment vars (page.php?var1=a&var2=b) have been posted, these will be added to $return

then to get back, just call

header("Location: $return");

nb browsers are very fussy about this header - all spaces etc must be as above!

no worries - if you need any more help, gimme a shout - i spent the other night working on that bit so that when users login to my site, they are taken back to their original location
