I Built a WordPress Plugin with Claude Code – Here’s What Actually Happened

Finding a post ID in WordPress is one of those things that sounds simple until you’re doing it for the tenth time that week.

You hover over the post, look at the URL in the status bar, squint at the number buried in ?post= and try to remember it long enough to paste it somewhere. Or you click into the editor just to grab the ID from the URL. It works. It’s also mildly annoying every single time.

So I built a plugin that adds a Copy ID button directly to the Posts and Pages list. One click, ID’s in your clipboard, done.

The interesting part? I built it with Claude Code. Start to finish.

TCPDF Was Adding a Second Page Silently – Here’s What Caused It and How I Fixed It

A user reported that their certificate was printing two pages instead of one. No error. No warning in the logs. Just a blank second page with some content on it that was supposed to be on page one.

That’s the worst kind of bug — silent, visual, and impossible to reproduce until you understand exactly what triggered it.

My Moodle Plugin Crashed on the Live Site Because I Added a Column Manually

I added a new column to my plugin’s database table. Tested locally — everything worked. Deployed to the live site — plugin crashed with a “Column not found” error in front of actual users.

The column was sitting in my local database. It was not on the live server. Of course it wasn’t. I had added it by running ALTER TABLE directly in phpMyAdmin. That only touched my local machine. The live server had no idea a new column was supposed to exist.

This is the mistake I see most Moodle developers make once. You do it, the live site breaks, you manually run the SQL on the server at odd hours, and then you learn there’s a proper way to do this.
