Help with HTTP_SERVER_VARS

[Anon]

Hi,

Is their a function that would retrieve a complete url including all of the server variables,(ex.www.myurl.com? id=123&name=joe...etc.),. What I am doing is creating a shopping cart that would allow me to go back to the last page I was browsing before I entered the shopping cart... a bookmark in a sense. I have used some of the http variables such as $URL allowing me to get the url but I can't figure out how to use the HTTP_SERVER_VARS[ ] array to get my server variables. Any suggestions would be helpful.

Thanks

Rick

reset ($HTTP_GET_VARS);
while (list ($key, $val) = each ($HTTP_GET_VARS)) {
// getvars (id, name etc.) are in $key
// $val is the value of var $key

}

To find out where a user came from (previous page) you can use Javascript : look for property document.referrer in your Javascript documentation.

good luck,
Jan
