sending a url through the url

[minuteman]

I am placing a "previous" link on a page. The previous page, however, is dynamicly generated. Thus the url of the page is always different. My plan is to retrieve the current url using $_SERVER['REQUEST_URI']; which returns something like this: /inventory/display.php?srtdata=make&begin=0&num=1&numBegin=1&search_value=x&search_column=pubshow
but can vary, depending on what the user has entered.
How can I send this value to the next page?

I thought I could assign it to a variable as in :
$newval = /inventory/display.php?srtdata=make&begin=0&num=1&numBegin=1&search_value=x&search_column=pubshow
and send it in the url but it can't be retrieved properly. When the parser hits the & it thinks it is a totally new variable instead of it being part of the $newval value. I've tried htmlspecialchars but couldn't get that to work (maybe because of syntax so if this should work what would the proper syntax be).

Thanks

have you tried using urlencode then assigning it to a variable?

I'd suggest just using javascript:

<a href="#" onClick="history.go(-1)">Back</a>
<a href="#" onClick="history.go(1)">Forward</a>

If you still want to use php, try \ all the & s

That got it! Thank you, very much!

$previous = $_SERVER['REQUEST_URI'];
$previous = urlencode($previous);

then pass $previous in the url to the next page. All the & and = signs are encoded and don't get read until $previous is entered into the link code.

Excellent!
