[RESOLVED] capturing URL "pieces" in reverse for mod_rewrite

[snailface]

Does anyone know how to do this, or if this is even possible.

In order to utilize mod_rewrite correctly for my site, I'd like to be able to capture only the last two parts of an entered URL for use as values in a query string in the translated URL.

For Example:
if the user enters: www.mysite.com/piece_1/piece_2/piece_3/

I only want to capture piece_2 and piece_3 in my regular expression for my rewrite rule.

---

if the user enters: www.mysite.com/piece_1/piece_2/piece_3/piece_4/

I only want piece_3 and piece_4

Is this at all possible? Or do I need to set up a new rewrite rule for every level of depth in the entered URL?

P.S. I know this sounds like an odd request, but rest assured that I have my reasons.

Yes it's possible... you need to use the "$" character to signify the end of the string. But you'd have to be 100% sure that the string ends in a "/", otherwise it won't work all the time.

Something like this might work:

RewriteRule ^.*/(.*?)/(.*?)/?$ new://place.to.be/

Something like that.... not 100% sure though.... try and find out 😉

Thanks bpat. I'm getting close. I'll let you know when I've got it all working.

Had to use 3 rules to catch everything:

RewriteRule ^([^/]*)/?$ tester.php?page=$1 [QSA,L] 
RewriteRule ^([^/]*)/([^/]*)/?$ tester.php?page=$2&parent=$1 [QSA,L] 
RewriteRule ^.*/([^/]*)/([^/]*)/?$ tester.php?page=$2&parent=$1 [QSA,L]

The tester.php file referenced in the rules is just something I put together for debugging to show me that the querystrings were coming through OK.
