Get Current User’s Role in WordPress
There’s no WordPress function to directly get the current user’s role, so I typically include my own function to serve that purpose, similar to the one below. This function is even more versatile since if you pass a specific user’s ID or User object to it, it will return that user’s role. If you pass nothing to it, […]

If you’re using Selectize to power your dropdown menus, you may find yourself wishing that when the user clicks the dropdown menu, the current value in the control would be cleared, leaving behind only a blinking cursor and the dropdown menu. This would make it very clear that the two options available to them are […]
Replace Post Meta Query with Taxonomy Query
In this post, I’ll cover how to replace a post meta query with a taxonomy query. Why, you ask? WordPress’ postmeta database table is not optimized for queries, so querying for posts based on their post meta like the below is inefficient. View the code on Gist.

Since the WordPress Customizer is built using the Underscore.js and Backbone.js libraries, the values of all the customizer controls are not stored in the DOM, but rather in a discrete model.
