Syncing Favorites

Hello,

I wanted to know how to sync all of my user’s favorite posts. For example, I have the favorite button in about three different places (a list of posts, on the post, and the page that shows the list of all the favorites). When the user clicks favorite on the post itself it is then favorited, but searching through all the posts I have to offer the user can find the post they favorited directly showing it’s not favorited ( but in reality it is favorited )… Simply put if it’s favorited in one spot I want it to show it is in all locations/unfavorite.

Thanks,
Christian
