On PHPBuilder.com today there's a new tutorial walking you through the creation of a simple WordPress plugin that shows the latest YouTube video from your blog's channel.

Think of plugins as components where you put your functionality and widgets as components of your user interface. Building your own WordPress plugins and widgets will make your blog truly original, and all you need is basic PHP and HTML knowledge - and your imagination.

They help you get started with defining a few constants, registering the actions with WordPress, building the widget (with complete cut-and-paste-able code) and including it in your WordPress blog. You can download the complete source if you want to get started quickly.

Alan Skorkin has a recent post to his blog about a trouble that many WordPress users have come across in working with their content and the WP-Syntax plugin (for displaying code) - a special character escaping bug that escapes characters that don't need it.

Suffice to say, [WP-Syntax] does the job fine except for one very annoying issue. Whenever you have any kind of special characters in your code (which you inevitably do e.g. <, >, & etc.), these always render as their escaped representations.

It only happens with the WYSIWYG editor for writing content (which the tool's FAQ recommends turning off) but there's a better solution that Alan found - change a line of code in the plugin to use the htmlspecialchars_decode function to rid your install of this pesky escaping bug.

On the Template Monster blog there's a recent post looking at some of the upcoming features in WordPress 3.0 that many WordPress site owners have eagerly been waiting for.

If you've been using your WordPress installation in a single-user fashion and have been looking to get more people in on the fun, you'll probably want to update to the WPMU edition of the popular blogging engine. It's not the easiest thing to accomplish, so the WordPress Arena site is here with a guide to walk you through each step of the way.

[WPMU] is most famously used for WordPress.com where it serves tens of millions of hits on millions of blogs each day. Many bloggers interested in using WordPress MU already have a WordPress blog. Unfortunately, I think it is not possible to turn WordPress installs into WordPress MU installs directly uploading new files and upgrading.

The post includes a 17-step process you'll need to follow to get your current WordPress installation migrated over intact (with a few sub-steps along the way). At the end, there's a brief tour of the new panels you'll have for things like the blogs, users, themes and administration.

In a new post to his blog Klaus Graefensteiner talks about one of the fastest ways to get WordPress installed and running on a Windows 7 platform - the Web Platform Installer.

his is the first installment of a series of blog post called the WIMPinator Chronicles that describe how to setup a PHP development environment for Windows 7 and IIS 7.5. In this part we are taking advantage of a very cool tool called the Web Platform Installer. With a few clicks you will be able to install and configure IIS7, PHP, MySQL and a Wordpress blog on your local Windows 7 computer.

With the Web Platform Installer, the installation of the needed software is just a few clicks (and configuration settings) away. Windows users will feel right at home. His screenshots guide you through the whole process and you'll end up with IIS, PHP and MySQL installed to run the WordPress blogging platform on your local machine.

Vid Luther has a recent post over on his blog today about using Phing to deploy WordPress to the cloud, more specifically to the Rackspace Cloud Sites.

My last post about Wordpress and Capistrano made people ask why wasn't I using Phing, and staying within the PHP ecosystem. The answer was simple, I wanted to learn Ruby, and I wanted to learn Capistrano. The question kept nagging me though, so I decided to find out how easy would it be to duplicate this in PHP.

He lists some of his requirements (as laid out in his Capistrano build) like made over a secure connection and can work with the Rackspace Cloud Sites. He came up against a few issues - some dealing with the platform, another about the tools installed - but besides that, things got working quickly. He includes the XML configuration file he used for Phing to get it all working happily.

WordPress users out there might find the latest post from Sameer Borate interesting if they're looking to squeeze the most performance out of their installation. It's a guide to using the FirePHP plugin for Firefox to benchmark your WordPress install's SQL.

The first thing you can do to rectify the situation is to find out where exactly the bottleneck resides by analyzing the time each SQL query takes to executes. Some inquisitive people among you may also be interested in knowing in what sequence the Wordpress SQL queries themselves are being run.

His method of benchmarking the SQL for the application uses some of the built in query logging in WordPress and some code dropped into your footer of your template to grab that information and push it back out to the waiting FireBug panel in your browser. The result looks something like this.

On the SitePoint PHP blog there's a recent post from Craig Buckler showing how to split up your WordPress content into two or more columns quickly and easily.

WordPress is a great CMS, but implementing some features within your theme can require a little lateral thinking. The content for your page or post is usually output by the theme code using a single function call. But what if you need to split the content into two or more blocks? That might be necessary if your theme requires multiple columns or sections on the page.

There's a built in call WordPress includes, "get_the_content", that returns the content rather than just echoing it out. With this handy function giving you just the content, you're free to split up the content however you want - on certain tags or as they suggest, using the "more..." tag and a few modifications to a few other scripts to split it out into DIV blocks.

Instead of comparing the software itself, the GnomeOnTheRun.com blog takes a look at the project homepages of three major PHP CMS/blogging tools - Joomla!, Drupal and WordPress - to see when they might tell us about the project itself. (Some of the homepages are actually built using the software too).

I found some interesting things that might shed some light onto the different projects. This is all based on January 11th, and 28th homepages, so by the time you read this a lot may have changed. Rather than go into great detail, I'll provide short lists of interesting things I noticed.

He looks at three different sides of the sites - how the markup is structured and if they conformed to an HTML standard, the overall performance of the sites and the actual content of the site (how useful it is, the organization, etc). You'll have to read the post to see what his conclusions were, though.
