From URL To Query–WordCamp San Francisco 2014

WordCamp San Francisco is today, and I’ve been invited to present a five-minute lightning talk as part of this afternoon’s program. Drawing from my longer talk of the same name (given at past WordCamps), From URL to Query describes the process WordPress undertakes to deliver the right content for each URL.

Ever wonder what process WordPress undertakes when someone visits your site? Or how it translates that nice permalink to the database query that ultimately delivers the content your visitors requested? Or what it takes to load the appropriate template from your site’s theme?

In this talk, I’ll walk through WordPress’ loading process and shed some light on the various APIs used. I’ll also discuss how these APIs work together to make the software function.
