Have you ever accidentally saved the same post meta to a post in WordPress, and ended up with a duplicate? Of course, you could go through each post and check the meta, check for duplicates, and delete any of them but… I think I’ve figured out a beast of an SQL query that will give […]

WordPress Post Meta and JSON

…or how I stopped worrying and learned to love the slashes. Post Meta in WordPress is a great tool to store random bits of data associated with your posts. But did you know that it comes with its own set of problems? Have you ever tried storing a JSON string inside of post meta? Only […]

Auto-enable WP_DEBUG with a cookie

One of the most important things to do when working on new themes, plugins, or debugging issues in WordPress is to turn on WP_DEBUG.  According to the Codex: WP_DEBUG is a PHP constant (a permanent global variable) that can be used to trigger the “debug” mode throughout WordPress. It is assumed to be false by […]
