Block Random String Comment Spam

Recently WordPress sites have been getting hammered with random-string comment spam. The attackers are clever, using random text strings for every vector except the payload, which usually is the URL used for the comment’s Name link. But for these weird comment spams, the apparent payload is the email address. It’s the only part of the comment that’s not made up of random gibberish. Continue reading »

WordPress get_comments_number() Not Working Correctly?

It seems that the WordPress function, get_comments_number(), is not working correctly. It is returning inconsistent results for posts with zero comments, pingbacks, or trackbacks. Sometimes the function returns true, other times false. It’s just random, from what I’ve been able to tell. So maybe a bug, or maybe something I am missing. Not a big deal, just looking for clues..

Why is there no 7G WordPress Plugin?

I have thought a lot about making an nG WordPress plugin. The problem is that writing to .htaccess via PHP/plugin is risky with lots of ways to fail and make users confused and angry. And nobody wants that, in fact just the opposite: my plugins strive to give users the most awesome experience possible. Continue reading »

New Book: Wizard’s SQL Recipes for WordPress

I’m excited to launch my latest web-dev book, Wizard’s SQL Recipes for WordPress. I got the idea for this book way back when I was first learning how to build dynamic websites. I thought it would be useful to bring together all of the best SQL snippets in sort of a “spellbook” or “cookbook”. After all, SQL queries can seem like magic to the uninitiated. By entering concise, well-crafted commands, SQL enables anyone to interact with any relational database. It’s […] Continue reading »
