Custom OpenSearch Functionality for Your Website

I recently added OpenSearch functionality to Perishable Press. Now, OpenSearch-enabled browsers such as Firefox and IE 7 alert users with the option to customize their browser’s built-in search feature with an exclusive OpenSearch-powered search option for Perishable Press. The autodiscovery feature of supportive browsers detects the custom search protocol and enables users to easily add it to their collection of readily available site-specific search options. Now, users may search the entire Perishable Press domain with the click of a button. And you can do it too! Adding customized OpenSearch-powered search functionality to your own site is a ...

Content Negotiation for XHTML Documents via PHP and htaccess

In this article, I discuss the different MIME types available for XHTML and explain a method for serving your documents with the optimal MIME type, depending on the capacity of the user agent. Using either htaccess or PHP for content negotiation, we can serve complete, standards-compliant markup for our document’s header information. This is especially helpful when dealing with Internet Explorer while serving a DOCTYPE of XHTML 1.1 along with the recommended XML declaration. According to the ...

An Easy Introduction to Web Feeds

This article will help beginners understand a few “feed” essentials: what they are, how they work, and how to use them.. So you are a little new to the Web. As you surf around, you keep noticing these little orange squares and multicolored boxes placed next to phrases such as these: Subscribe via RSS Subscribe via XML Subscribe via Atom Subscribe via Feedburner Subscribe to My Feed Subscribe to Main Content Subscribe to Comments ..and so on. Although these invitations to “subscribe” come in many flavors, they are ...

Error-Free Feed-Validation Links for Feedburner-Redirected Feeds

Just a quick tip on how to create error-free links to feed validation services for feeds that are redirected through Feedburner. For example, let’s say our site’s main feed is originally located at: http://domain.tld/feed/ If we wanted to provide our visitors with a link that would enable them to automatically validate our feed using a free service such as feedvalidator.org 1, we would create the link as follows: Validate our Feed ..which would do the job nicely. However, if we are redirecting our feed through Feedburner, the previous link will return an error, as the feed URL now registers as the following: http://feeds.feedburner.com/myfeedname ..depending on the Feedburner name ...

Laser-Focused Feeds and Smarter Feed Management

My current adventure into the fascinating realms of site redesign and optimization has yielded several chunks of fruit related to managing and delivering feed content. One of my primary concerns regarding the overhaul of Perishable Press is streamlined content delivery and rights management. An important area of convergence for these two factors involves the management and delivery of a site’s syndicated content. In this article, I explain the shortcomings of many default feed configurations and present an effective overall strategy for better feed management. When it comes to managing syndicated content, ...

What is the Difference Between XHTML 1.0 Strict and XHTML 1.1?

As some of you (e.g., Louis) may have noticed during the recent site redesign, I decided to switch the default doctype from XHTML 1.0 Strict to XHTML 1.1. Just in case you were wondering, XHTML 1.1 is different than XHTML 1.0 in three important ways 1: On every element, the lang attribute has been removed in favor of the xml:lang attribute On the a and map elements, the name attribute has been removed in favor of the id attribute The “ruby” collection of elements has been ...

New Version of Category LiveBookmarks Plus for WordPress 2.3

CLB+ As many WordPress users now realize, there have been many fundamental changes in the new version of WordPress. The latest version of WordPress — 2.3 — features a considerably revamped database structure, including a complete reorganization and redistribution of the wp_categories table. Unfortunately, such database alterations have rendered inoperable many popular plugins, proving quite unfortunate not only for millions of WordPress users, but also for those of us who donate time, effort, and resources toward the development of freely available WordPress plugins. Thus, with the advent of WordPress 2.3, developers whose plugins have ceased to function must now decide whether or not to ...

Feed your Image via Atom or RSS

This quick tutorial explains how to add images to both Atom and RSS feeds. Although both formats allow for image-inclusion, feed-reader support for image-display is currently quite limited. Hopefully, that will change in the near future.. Images for Atom Feeds Images included within Atom feeds must have a ratio of either 1:1 or 2:1. There are no other restrictions as to file type or size. Use the XML element for URL’s targeting 1:1 images. Otherwise, use the XML element for URL’s targeting 2:1 images. Either element should be placed in the element: http://domain.tld/path/icon.ico http://domain.tld/path/logo.gif Images for RSS Feeds RSS supports images with a maximum width of 144px and ...

Feed Tester

Ignore this post.. [Edit] Note to WP 2.0.5 users: Everything was working fine on this site before upgrading to WP 2.0.5. After upgrading, apparently, our feeds stopped validating* and the BDP RSS Aggregator plugin refused to update our own feeds. After several hours investigating the situation, we determined that the Live Comment Preview plugin was interfering with our feeds validating, while the upgraded WordPress (2.0.5) was responsible for problems with the BDP plugin. Here is a copy of our recent comment posted at the BDP plugin website: Comment by m0n on Wednesday 6 December 2006 at 4:28 am I was running ...

Add RSS Feed Link Icons to WordPress Category Listings

This brief tutorial explains two methods for adding RSS feed link icons to category listings. Let’s say that you have a list of category links, where each link targets a specific category view. Now let’s say that, next to each category link, you would like to provide a icon that links to that particular category’s syndicated feed. So, rather than cluttering up your page with two sets of category links -- one for category views and another for category feeds -- consolidate links and simplify your site by providing both sets of links in a logical, streamlined format. Method One: A Static Category/Category-Feed List via wp_list_cat...

WordPress RDF Source Makeover

Beautiful Source-Code Output, Part 1: Whip your WordPress RDF Code into Submission Update: This article applies specifically to WordPress 2.0.2, but may be generalized to any WP 2.0+ version. I love looking at beautiful source-code output. However WordPress tends to spit code out in random chunks, often leaving spaces, line breaks, and tabs littered throughout the source output. This messes things up. Lists don’t look like lists and logically written code often appears scattered along the page carelessly. Often, this is the result of poorly written PHP, which can be manipulated to write beautifully aligned code that looks as good as it works. For the first article in this series, we will bring order ...
