Welcome to WordPress. This is your first post. Edit or delete it, then start writing!

We also update the meta using the functionupdate_post_meta(). I usually prefer using this over add_post_meta() because, if there’s no meta in place, update_post_meta() will add it anyway.

Now we check if $processed_like is true. If the post meta updated, then it will be true, because update_post_meta() returns true on success. If it is true, we set the current permalink as the redirect.

The reason we have to do a redirect is that if we didn’t and just loaded the page with ?post_action=like still in the URL, if the user copied that URL or simply refreshed the page, it would add another like.

Thanks for following along with the tutorial and I hope it’s been helpful to you!
