I’d like to add a custom function to my WP site. Visitors would be able to click a button to “like” a post, much like Google’s +1. Only one option: click to like.
My thought is to store the likes by incrementing a value in post-meta, then add that to the post’s query to display the number.
Can anyone point me to online tutorials, scripts, or plugins that might help me? I’m not a programmer, but I can understand and edit most PHP and js. I just don’t know where to start, and searches haven’t turned up anything yet.
