I have created a hit counter that stores all time hits and daily hits. This means that if a single post gets at least one view a day it will have 365 meta fields added to it by the end of the year. Multiply this by N posts and the number can grow considerably large. Will this ever be an issue? I know Wordpress caches stuff and this is why i am worried about it. Will all of these be loaded each time the post is loaded.
This will better explain what i have implemented.
$dailyhits = get_post_meta( $post->ID, 'hits_'.date('Y-m-d'), true ); if($dailyhits == null || $dailyhits == "" || $dailyhits == false) $dailyhits = 1; else $dailyhits = $dailyhits + 1; update_post_meta($post->ID, 'hits_'.date('Y-m-d'), $dailyhits);
