There are many ways to navigate a WordPress-powered site. There are archive links, category links, page links, internal post links, single post links, admin comment links, tag links, and many other types of navigational links. When it comes to navigating sequentially through your site’s chronological archive pages, category archives, and other types of archive pages, WordPress provides several useful template tags designed to dynamically link the pages together. Likewise, for single permalink post-views, WordPress provides a set of template tags that connects the pages together in chronologically sequential fashion.
Since WordPress 2.8, we can target specific types of page views with CSS using the new
body_class() tag. Designed for use within the

Recently, I found myself on the front lines of WordPress’ somewhat complicated Media-Library system. The site that I was developing required a rather elaborate system of retrieving and displaying image attachments. So, using the latest version of WordPress (2.8.3 at the time), I found myself experimenting with as many template tags and custom functions as I could find. After much experimentation, I discovered the perfect solution, and along the way I collected a healthy collection of recipes for displaying image attachments and their various types of associated information.
Did you know that WordPress makes it super-easy to display some basic statistics about your database performance? The information may be displayed publicly on your web page, slightly hidden in your source code, or entirely private so only you can see it. There are two basic statistics that are drop-dead easy to include on your pages:
Out of the thousands of plugins available for WordPress, there is one that all WordPress users are familiar with: Hello Dolly. As far as I know, the Hello Dolly plugin was the first WordPress plugin and has been included with every version of WordPress. The plugin is so familiar that many WordPress users don’t even think about it. They either activate the plugin or delete it without giving it a second thought. But if you actually stop to think about it for a moment, the following questions seem inescapable:
Close monitoring of your site’s PHP errors is crucial to operating a healthy, secure, and well-performing website. When left undetected, PHP errors can reduce performance, waste bandwidth, and leave your site vulnerable to malicious attack. PHP errors usually occur unpredictably and spontaneously, and may be triggered by even the slightest changes to your server configuration, database setup, or WordPress files.
