Until a few years ago, I hadn’t written a single WordPress plugin. I had created and customized many themes for our clients, but for some reason, I kept telling myself that creating a plugin was beyond my capabilities. In hindsight, I couldn’t have been more wrong. If you’ve ever felt this way, let me tell you something. Creating a WordPress plugin is not beyond your capabilities. Anyone that has skills enough to write basic PHP and modify a theme can create a plugin.
