Four years later, people continue to tell me how much they enjoy and use the content as a bookmarked reference for many of their HTAccess needs. The article was even published in a book on Joomla! Security. This is very inspiring to me, so I have decided to create a similar post for all of the useful WordPress code snippets, tips and tricks that I have collected […] Read more »

Unobtrusive JavaScript for ‘Print-This’ Links

One of the oldest JavaScript tricks in the book involves providing a “print this!” link for visitors that enables them to summon their operating system’s default print dialogue box to facilitate quick and easy printing of whatever page they happen to be viewing. With the old way of pulling this little stunt, we write this in the markup comprising the target “print this!” link in question: <a href=”javascript:window.print()”>Print This!</a> Big yuck there, of course, due to the obtrusive nature of the JavaScript implementation. Adhering to the principles of proper Web Standards, it is better practice to separate behavior from structure […] Read more »

WordPress Custom Fields, Part I: The Basics

I recently developed a theme that makes heavy use of WordPress’ custom fields. The custom-field functionality of WordPress makes it possible to rig up just about any customized layout quickly and easily. Custom fields enable designers to organize post content into different sections, making it possible to create non-linear page layouts, with different types of content easily removed from the normal post loop and relocated to different parts of the document. This organizational and design flexibility has the added benefit of making it super-easy to update your content, redesign your theme, and handle blog maintenance in general. In the first […] Read more »

Perfect WordPress Title Tags Redux

In my previous article on WordPress title tags, How to Generate Perfect WordPress Title Tags without a Plugin, We explore everything needed to create perfect titles for your WordPress-powered site. After discussing the functionality and implementation of various code examples, the article concludes with a “perfect” title-tag script that covers all the bases. Or so I thought.. Some time after the article had been posted, Mat8iou chimed in with a couple of ways to improve thie script by cleaning up tag names and specifying page numbers for archive views. Apparently, by replacing the $tag variable with WordPress’ built-in single_tag_title();, titles […] Read more »

Fruit Loop: Separate any Number of Odd and Even Posts from any Category in WordPress

Recently, I discussed how to implement a horizontally sequenced display order for WordPress posts in two columns. In that tutorial, I explain how to separate odd and even posts using a dual-loop configuration and PHP’s modulus operator. Such technique serves well a variety of configurational scenarios, but is limited to the display of the default (admin-specified) number of posts from all categories. In this tutorial, we adapt this odd-and-even loop configuration to accommodate a much greater degree of customization. Specifically, we will focus on separating any number of odd and even posts from any specific category or group of categories. […] Read more »

Better Default Directory Views with HTAccess

Beautify your default directory listings! Displaying index-less file views is a great way to share files, but the drab, bare-bones interface is difficult to integrate into existing designs. While there are many scripts available to customize the appearance and functionality of default directory navigation, most of these methods are either too complicated, too invasive, or otherwise insufficient for expedient directory styling. In this comprehensive tutorial, you will learn how to use the built-in functionality of Apache’s mod_autoindex module to style and enhance your default directory views with a smorgasbord of stylistic and functional improvements.

Redirecting Subdirectories to the Root Directory via HTAccess

One of the most useful techniques in my HTAccess toolbox involves URL redirection using Apache’s RedirectMatch directive. With RedirectMatch, you get the powerful regex pattern matching available in the mod_alias module combined with the simplicity and effectiveness of the Redirect directive. This hybrid functionality makes RedirectMatch the ideal method for highly specific redirection. In this tutorial, we will explore the application of RedirectMatch as it applies to one of the most difficult redirect scenarios: redirecting all requests for a specific subdirectory (or any subordinate directory or file) to the root (or any parent) directory. We will explore how to accomplish […] Read more »

Multiple Loops and Multiple Columns with WordPress, (X)HTML and CSS

How to Generate Perfect WordPress Title Tags without a Plugin

Keeping an eye on all things WordPress, I have noticed an ongoing fascination with configuring the ultimate WordPress <title></title> tags. Many bloggers use various plugins to generate differently configured <title></title> tags depending on particular page views. A good example of this is seen in the All in One SEO Pack, which, among many other things, enables users to specify custom titles for several different types of pages. While there is nothing wrong with this approach, some of us prefer to run WordPress with as few plugins as possible. If you want to create perfect WordPress title tags without a plugin, […] Read more »
