URI safe pagination patch - El Forum - 10-30-2007
[eluser]kylehase[/eluser]
This is patch to the pagination class that aims to provide pagination without breaking other URI data. For instance if your URI is something like:
example.com/class/method/search/phone/sort/price or
example.com/class/method/filter/online
The page links will preserve the extra URI fields:
example.com/class/method/20/search/phone/sort/price or
example.com/class/method/40/filter/online etc.
Your class must be able to parse the URI with or without the page number.
See http://ellislab.com/forums/viewthread/63531/ for help with that.
