Show last post of previous page as first on next?

[ia7]

Hi vB coding gurus, I have a question that's probably been asked maybe a number of times (a google search is hard to get right).

Is it possible to create a plug-in that will make 'showthread' show the last post of the previous page as the first post on the next page?

Example: Say 20 posts per page. I want that 20th post to show as the first post on Page 2 and so on. Why? Well as you get on a bit you forget what you saw 5secs earlier and so having that topic of discussion being readily available will make it easier to continue it on... hopefully! :D

I'm not looking for a global first page or anything, I've already seen them. :)

I had a look at showthread.php but it made me cry a little so I'm asking you, the wise ones, if this is possible to do and how.

Thanks.

Hmm...I guess you could try subtracting 1 from $lowerlimit if it's not 0, then I think you'd also need to increase the number of posts read when $perpage is used, to be $perpage + 1. I haven't tried it but I have a feeling if you were to just add one to $perpage, the page counters wouldn't work right.

Maybe another approach would be to only display $perpage posts, but calculate the first post based on the page (that's what's done now, but it just uses $limitlower = ($vbulletin->GPC['pagenumber'] - 1) * $perpage) But that way, I don't know if the page numbers make sense. It might be easier to just have the post from the previous page be in addition to $perpage.

Thanks kh99 I'll try some of those suggestions out on my test board. Appreciate the reply.
