WP Custom Fields, Part II: Tips and Tricks

[ Magnetic Fields ]

As we have seen in our previous post, WordPress Custom Fields Part I, custom fields provide an excellent way to add flexible content to your posts and pages. By assigning various types of content to different custom fields, you gain complete control over when, where, and how to display the associated information. For example, sub-headings may be displayed in the sidebar, footnotes may be consolidated into a single region, post images may be displayed before the post title, and so […] Continue reading »

WordPress Custom Fields, Part I: The Basics

[ Magnetic Fields ]

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 […] Continue reading »

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 […] Continue reading »

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

[ Fruit Loop ]

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, […] Continue reading »

Yahoo! Lies about Obeying Robots.txt Directives

There are two possibilities here: Yahoo!’s Slurp crawler is broken or Yahoo! lies about obeying Robots directives. Either case isn’t good. Slurp just can’t seem to keep its nose out of my private business. And, as I’ve discussed before, this happens all the time. Here are the two most recent offenses, as recorded in the log file for my blackhole spider trap: Continue reading »

Better Default Directory Views with HTAccess

[ Screenshot: Default Directory View ]

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 […] Continue reading »

Blacklist Candidate 2008-10-19

[ Photo: Television Flashback ]

Welcome to the Perishable Press “Blacklist Candidate” series. In this post, we continue our new tradition of exposing, humiliating and banishing spammers, crackers and other worthless scumbags.. From time to time on the show, a contestant places a bid that is so absurd and so asinine that you literally laugh out loud, point at the monitor, and openly ridicule the pathetic loser. On such occasions, even the host of the show will laugh and mock the idiocy. Of course, this […] Continue reading »

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 […] Continue reading »

Evil Incarnate, but Easily Blocked

As my readers know, I spend a lot of time digging through error logs, preventing attacks, and reporting results. Occasionally, some moron will pull a stunt that deserves exposure, public humiliation, and banishment. There is certainly no lack of this type of nonsense, as many of you are well-aware. 3G Blacklist Even so, I have to admit that I am very happy with my latest strategy against crackers, spammers, and other scumbags, namely, the 3G Blacklist. Since implementing this effective […] Continue reading »

Secrets of the Conditional Tag Revealed: How to Gain More Control Over Your WP Templates

More and more these days, we are all finding WordPress being used as a content management system. It shouldn’t be too tough to see why — highly customizable, a community growing in size and knowledge, and a plethora of options in the way of plugins and simple yet highly effective PHP edits. Thanks to these, you have access to an open source script that allows you to show what you want, when you want, where you want, and how you […] Continue reading »

Yahoo! Once Again Caught Disobeying Robots.txt Rules

Hmmm.. Let’s see here. Google can do it. MSN/Live can do it. Even Ask can do it. So why oh why can’t Yahoo’s grubby Slurp crawler manage to adhere to robots.txt crawl directives? Just when I thought Yahoo! finally figured it out, I discover more Slurp tracks in my Blackhole trap for bad spiders: Continue reading »

How to Generate Perfect WordPress Title Tags without a Plugin

[ Perfect Title Tags ]

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 […] Continue reading »

Unexplained Crawl Behavior Involving Tagged Query Strings

I need your help! I am losing my mind trying to solve another baffling mystery. For the past three or four months, I have been recording many 404 Errors generated from msnbot, Yahoo-Slurp, and other spider crawls. These errors result from invalid requests for URLs containing query strings such as the following: https://example.com/press/page/2/?tag=spam https://example.com/press/page/3/?tag=code https://example.com/press/page/2/?tag=email https://example.com/press/page/2/?tag=xhtml https://example.com/press/page/4/?tag=notes https://example.com/press/page/2/?tag=flash https://example.com/press/page/2/?tag=links https://example.com/press/page/3/?tag=theme https://example.com/press/page/2/?tag=press Note: For these example URLs, I replaced my domain, perishablepress.com with the generic example.com.
