In-depth overview from Paul Kaiser on how WordPress 3.0 is expanding and improving upon creating custom taxonomies, including how they can now be hierarchical. Most importantly Paul shows how (and why) they can be used in themes.
Some quick notes and news about the book!
Anything you create in the global namespace has the potential to conflict with a theme, another plugin (including one you wrote), and WordPress core itself. Thus, prefix everything with a unique-enough character set. For example, all functions I write always start with “nacin_”, and I make sure that my functions are unique across all of my plugins.
In this recent post, I used some fairly generic function names like
custom_css_hooks. Andrew is saying that names like that are a little too generic and that it's possible another plugin could use that same name which would be rather disastrous. Since it's totally internal anyway, I should have called it
digwp_custom_css_hooks, which would be far less likely to meet a conflict.
Yes, it runs WordPress on Windows and SQL Server.

I'm a HUGE fan of being able to link up a CSS file on a per-page basis. I just find it extremely common that a page needs CSS styling unique to it, and I hate litering a sites main stylesheet with customizations that only one particular page needs. We've talked about this before, and even created a custom method for doing so, as well as mentioned the art direction plugin, which makes this easily possible.
Recently, WPRecipes posted an incredibly useful technique that uses a shortcode to add private content to blog posts. This functionality makes it easy to manage leftover data, miscellaneous notes and other communication by keeping everything together with its corresponding post. Consolidating information like this helps to streamline flow and organization into the future.
HTML5 is rapidly gaining popularity, but how many people are actually using it? If not HTML5, then what? When creating websites, designers have a variety of options for markup:
The titles of pages are controlled by the <title> tag in the <head> section of a website. They are important for all kinds of reasons. Telling the user where they are. The name of the page when bookmarked both locally and socially. They are important for SEO.
WordPress provides several navigational template tags to make it easy for visitors to surf your pages. There are basically two different types of template tags used for chronological post navigation:
Back in January, we asked How Do You Use the WordPress Media Library?. After more than 700 votes, the results are in:
Really nice article running down the major caching plugins, including some ones I have never heard of. I'm a fan of W3 Total Cache myself, having tried about four of them on various sites. I like the CDN integration, the fact that it doesn't change your URLs, and that it combines file and database caching. Not to mention it is actively maintained.
Most interesting are the options that turn out to be worse that no caching at all.
CSS-Tricks does nearly 2.5 million pageviews a month and can run OK without caching, it's just much faster and surge-protected with it on.
When the iPad came out I was able to convince myself that it really is my responsibility as a publisher of a digital book that I should have this device for testing. Ha! Yeah right, I just thought they were cool and wanted one. So the big question is...
We covered how to run a shortcode in a widget. But what about inserting a widget with a shortcode? I recently had this situation come up. I had a single page where I just wanted to be able to chuck in a widget without the whole rigmarole of creating a special widgetized area and probably a custom page template for that widgetized area and such. I wanted to just put [widget widget_name="my_widget"] in the pages content and have that widget pop in. Turns out it wasn't as easy I wanted it to be, but it's not that bad...
In a recent post, we show you how to clean up and enhance the functionality of WordPress with a custom functions.php template. In that post, we explain how using a custom
