Ok, together with r20714 (removing unsed variable only) the backwards scrolling isn't completely fixed :-( The current version is a little bit better because it is possible to scroll once back, the second click jumps to the beginning of the list in correct order. The previous version jumps at the first backwards click to the beginning of the list, in reversed order. I think we need a database request to figure out the offset for every backwards scrolling in dependency of the current page and the limit. But I do not know how to do this in the cheapest way, without melting the servers :-(
What this needs is a "to" parameter, to specify a maximum id. Pseudo-code would be: SELECT ... FROM table WHERE id < 1234 ORDER BY id DESC LIMIT 50 Then you need to reverse the result set in PHP.
Should be fixed by Aaron in r35371.
r35371 and friends reverted as they don't work on MySQL 4.0.
