I achieve to do that hacking the “wp_ulike” class in the function “loggedby_ip_method”.
I added an ADD term to the mysql for the $is_user_liked_before : AND date_time
> date_sub(now(),INTERVAL 1 DAY)
Some problems doing this :
– I hacked the plugin, i know it is the wrong way, but i didn’t see any hooks to filter the query
– As others functions simply update the like status of this ip without taking account the current ID of the like, all nexts likes/dislikes will update every likes done by this ip, so statistics will be wrong.
