WPBeginner has published an article that explains how they used the WP Favorite Posts plugin to give one of their clients a “personalized library” for their users which allowed them to favorite videos that they could watch repeatedly. In the article, they also explain how to use the plugin to provide that same personalized experience for your own site so that registered users or non-registered users could favorite specific posts that they could access later. It’s a cool plugin but upon reading the directions on how to display the favorite option within specific pages or posts, I was sent back into time because in order to accomplish that task, you need to add specific code to certain template files such as page.php, single.php, etc. I thought that practice of adding plugin functionality was gone but I guess not.
