When you are building a theme, and the circumstance comes up where you need to create a link to a specific page hard-baked right into the theme, there is a function you should be using.

I was talking with Darren Hoyt recently about building a better interactive button (404 link removed 2013/11/17). The goal of the button was to provide three states: regular, hover, and active (pressed). That is standard of any good button, but we were going to integrate some fading effects into it to really making the button satisfying to interact with. Here is a demo, and now we are going to show you how to integrate it into WordPress.
I've always used plugins for breadcrumbs, but of course rolling your own is always appealing. Gilbert Pellegrom shows us how to do it with our own custom functions.
Over on CSS-Tricks, I describe a problem I had of trying to create an RSS feed of pages that were buried two deep under a parent page. The standard query_posts can't go two levels deep with pages, or accept multiple parent pages to run the query. Instead I had to create multiple feeds from a custom template and stitch them together.
UPDATE: Make sure to take out "Take Two" on this concept, with a cleaner method for doing this.
Custom fields allow us to attach data to Posts or Pages that we can yank out and use at will in our templates. They are awesomely flexible and single-handedly allow WordPress to be used for about any CMS need. The fact that they can only be used on single Posts can be limiting in some circumstances. Sometimes you wish you could grab a custom value that you can control and is consistent globally, regardless of the current post. In this post we'll look at a technique to do so.
Let's say you were going to start a music review site where you review individual songs. Words are great, but in this context they aren't going to mean much unless you have the song right there to go with it that can be listened to. This presents some interesting legal problems. You can't just upload your own copy of the song to your web server and use some kind of MP3 player on your website to present the song. That is illegal distribution of the MP3 that could get you into trouble.
Use the WP-DB-Backup Plugin, have it send a copy to your email. This is what we do on DiW and it works great. Part of security is having clean and recent copies of your data in case of failure.

WordPress is like Windows, it's a huge target so hackers are extra-motivated to exploit it.There has been a bunch of brew-ha-ha over WordPress security over the last week or so. It started off a few weeks ago with a really easy URL hack to reset the Admin's password. That ballooned into a far nastier exploit allowing a new admin to be created who could totally hose a site. Matt Mullenweg does a little damage control here by essentially saying the best way to stay secure is to stay updated to the latest version. I wholeheartedly agree, and think that that step is just a part of a complete security breakfast (the upcoming book will have lots on security). I have probably nearly 20 WordPress sites I maintain and every single one of them was at 2.8.4. It's so trivially easy to upgrade, It's a no-brainer.
WordPress is a CMS. The whole idea being to manage content and make websites editable without having to wrangle code. Any theme can handle Posts and Pages, but what about those "smaller" areas. Little chunks of text placed around a design like a small "about" section, or the copy in the footer of a website. A lot of times this text is hard-baked right into the theme, which isn't a very friendly way to do things, as it can't be updated by average Joe user.
WordPress is a CMS out of the box, but sites that are really deep in page templates and hierarchies can benefit from some help on the back end for managing them all. This roundup of plugins do just that.
