realy its great mod
but does this mod get data from the user system?
if do it what about this mod load on server
I do not really understand first question... But I'll try to explain how do things work.
1) MOD with id=7 (postua) adds `user_ua` field in `phpbb_posts` table. It also extends submit function that the user agent is read when user posts. It is stored fo further use.
2) MOD with id=15 (feature-gfxua) adds images and functions to convert raw Useragent into System/browser strings
3) This MOD uses both of these features to read data from all user's posts and to process them. It takes some time (but really: this is fast by itself unless someone is using thousends of user-agents
), so resulting data is stored in cache (one cache file for each user). The cache is used when another user want to view profile. Cache is destroyed when user submits another post. So the impact on system load is minimal.
There are also my MODs that display textual and graphical User-Agent in viewtopic for each post, but they are so simple that there is no point to upload them here, I guess (until someone asks for them).
They (all of them, actually) can be installed, however, by phPKG.
