Question

I had an issue playing with Gallery when I changed a setting. However, I noticed there is a pattern to the error:

The URLs look as such:
main.php/d/number/name.jpg

“number” is dynamic (ie “9496-2”)
“name” is dynamic (ie “all+clad+7pc+b”)

Everything else is static.

Unfortunately, when I made the setting change, the “number” portion then changed from “9496-2” to “9495-2”.

How can I subtract the value “1” from variable “number”?

Answer 1

This should do it.

RewriteEngine On
RewriteBase /
RewriteRule ^photos/ebay/main.php/d/([0-9]*)6-([0-9]*)/(.*).jpg /photos/ebay/main.php/d/$1\5-$2/$3.jpg [QSA,L]

I know you said you already got it but here is a solution without an additional script. (And I actually tested this one to ensure that \5 works).
