Before you will be able to use it, though, you will need a theme that supports it. Most of the customizations you would like to make are included in a well designed theme with the proper support.

Matt Mullenweg said: "Child themes are the only way you should build your WordPress site on top of a framework."

Why are child themes the only way to build? If your theme updates and you don't use a child theme, all your changes will be lost. And if you don't update, you're site may well be insecure.

So, child themes are great. But the sad fact is almost no-one uses them.

firebugIt can be difficult to edit WordPress templates. Many have a lot of CSS files, which makes it difficult to test and to make changes.

UPDATE: Firebug is not supported anymore. Please try Dev Tools in Firefox, or Developer Tools in Chrome instead.

We recommend that you use Firefox to help you edit WordPress themes.

Firefox is a great browser but also a great tool for working with themes. Firebug is an add-on for Firefox that gives you two really important powers:

  • You can test template design changes before you make them.
  • You can quickly track down the exact file and line number where you need to make changes.

In this tutorial, we're going to show you how to use Firebug. We're going to edit the site title in the default WordPress Twenty Eleven theme.

Have you ever experienced Microsoft's famous Blue Screen Of Death? Well, WordPress has its own version commonly called the White Screen Of Death.

You are most likely to see this after upgrading WordPress to a new version, adding a plugin or a theme. 

It is possible to turn on debug mode to find the problem, but that won't really help if all you can see is a blank screen. Here are some ways in which you can recover from the White Screen of Death.

Right before we jump into this tutorial, we’d like to mention an alternative method that you might find both faster and easier. As you know WordPress as a CMS relies on plugins to extend its core functionality, and one such plugin for this use case is Modula. Modula is an easy-to-use WordPress gallery plugin that makes adding flexible photo and video galleries to your website easier than ever. You can learn more about Modula by clicking here or get started right away by downloading the free plugin from the WordPress plugin repository by clicking here.

There are tens of thousands of plugins on WordPress.org, but it's amazing how much you can get done with the WordPress core and just a plugin or two.

In this tutorial we're going to show you how to create a sleek photo gallery with elegant pop-ups, all using just a default WordPress site plus only one plugin.

Step 1. Add a new post or new page

  • Click Add New for either a post or a page.
  • Click the Upload/Insert icon.

Step 2. Add a list of images to that page or post

  • Open your file explorer and drag and drop a group of photos to the " Drop files here" Box.
  • If you are successful, the image files will be listed and you will see progress bars to show you they're uploading.
  • When every one is uploaded, click Save all changes at the bottom of the list. Scroll down to see it if it's not visible.
  • There will now be gallery tab at the top of the window. This tab is specific to this page or post. If you add a new page or post, you won't see this tab until you have uploaded pictures.

Step 3. Adjust settings and add the gallery

  • Scroll to the bottom of the window.
  • Choose your Gallery Settings.
  • Click Insert gallery.

Step 4. Customize the page

  • Now you will see a gallery icon in the center of the area where you inserted your gallery.
  • You can insert text or images above or below this section to customize the page.

Step 5. View the page to see the gallery

  • The thumbnails will show based on the settings you chose.

So far so good. However, if you click on the individual images, all you see are the images flat on the page. To get a really nice pop-up effect, we'll need to add a plugin.

Step 6. Add the lightbox effect

  • Go to Plugins > Add New.
  • Search for "jQuery Lightbox For Native Galleries".
  • Install Now.
  • Activate the Plugin.
  • Go to Settings > jQuery Lightbox.
  • Choose your theme.
  • View your gallery and click a thumbnail. Your images will pop up on a light box with navigation control and image count.


You now have a photo gallery with a lightbox effect installed. You can make further enhancements with additional plugins. For example you can create Multiple Galleries with this extension http://wordpress.org/extend/plugins/multiple-galleries/.

"Taxonomy" is a confusing word and one that many people don't like. It's hard to remember, it contains the word "tax", and it sounds like a little too much like "taxidermy" for comfort.

However, recently WordPress has adopted the word "taxonomy" as an additional way to organize information in more advanced ways than can be done with tags and categories.

In this example, we're going to show you how to create a full staff directory. After reading this tutorial, you'll be able to create a page for your company, sub-pages for each department in your company and finally place all your staff members into a department.

Custom Content Type ManagerOver the last few years people have been pushing the boundaries of WordPress as a CMS.

CTM allows you to create custom post types and add fields to them. You can add images checkboxes, textareas, and dropdowns and much more. And you can do all of this with little to no coding knowledge.

Child themes are the professional way to modify WordPress themes. Matt Mullenweg who founded WordPress said that "child themes are the only way you should build your WordPress site on top of a [another theme]".

A child theme can use all of the functions, CSS and design features from a parent theme. The child themes only needs to contain the details it wants to change.

In this tutorial we'll use the default Twenty-Eleven theme as an example parent theme.

The beta version of WordPress 3.4 is out.

So what's new? At first glance, you might say "not much". Unlike version 3.3, there are no easily visible changes to the admin area.

WordPress 3.4 is all about making theme customization easier, but even when you click on Appearance, you still won't notice any changes.

It's only when you dig deeper that you start to notice the magic.

We often get asked for our favorite plugins and so here's a list of some of the favorites used by the staff at OSTraining.

wordpress-logo-stacked-rgbWordPress started out as a simple way to share your thoughts on the web through, what was then, a new concept, blogging. People wanted to keep "web logs" of their thoughts and have other people read them and contribute comments. So WordPress was born to blog and it still does an outstanding job, but has grown into a content management system (CMS) which is something much more.

WordPress is truly astounding. Whether pushing content to social networks, competing for sales and search engine position, allowing people to subscribe to specific content WordPress is not simply a website, but rather a content-publishing platform. It allows you to take part in today's "instant" information network - the internet. It gives an individual the same publishing power as a major corporation.

WordPress is an interface


We use the term interface quite a lot. Originally it was coined to describe a method of passing information between two very different items. Sometimes between two machines (a hardware interface) to let a computer trade information with a printer as an example. A keyboard lets humans talk to computers; it's also an interface. WordPress is an interface that simplifies the way you communicate with a database. It lets you create and manipulate data with a GUI (Graphic User Interface).

WordPress makes it possible to publish all types of information without knowing how to write code. Anyone can start using a well-setup site without much training. It's fairly intuitive since it has evolved from years of user feedback and constant revision.

WordPress is a publishing platform


The success of early bloggers created a demand for an easy way to publish news or opinions instantly. Remember the Drudge Report during the Clinton Administration? The Drudge Report was an "aggeregator" which pulled news stories and blog entries from other sources and posted them in an aggegated blog. The notariaty of the Drudge Report is only one example of what fueled the demand for easy blog creation.

The first web pages were built one page at a time by writing all the information into a file and making it look good by writing mark-up code (HTML- Hypertext Markup Language). It might take hours to create a single page on a site.

Not very efficient for the "blogosphere", where compettiion for top blogs dependend on instant publishing. This meant that the person doing the writing couldn't always be the same person that did the web development. Information was created faster than it could be disseminated by coding pages with HTML.

The concept of "database driven" websites came about. Partly because of blogs, but also because of demands of web developer to make data available on demand. In a database driven site, all the stories and pictures are stored in a data base, and the actual pages are created only when someone visits the actual URL of the page. Showing and sellng products, creating portfolios, making directories all have a common base of data that needs to be assembled and presented on demand, in different combinations and with different looks.

You could write out various applications and programs for this, but the WordPress developers have written out the programming for you. Now you have a simple, graphical way to enter information into the database. They have also written out the most common ways to display it. And now since all this data is so well organized, other people can write applications which use the same data in different ways or allow you to add new data and combine it with the old. That's what plugins are for. They expand the core capabilities of WordPress with additional applications.

WordPress is a Content Management System


Publishing content isn't easy. It changes all the time. New content is added, old deleted. In ecommerce, prices change, sales and promotions come and go. Information needs to be very fluid, and WordPress lets you manage this ebb an flow. It also writes rules for you. For example, it will let registered users see a post, but hide it from people who aren't registered users. But managing the information isn't it's only function.

This information also has to look good and be organized properly. The underlying programing has to be safe, fast and up-to-date. Design and technology change as well as the information. WordPress handles this by separating the functions so a change in one area doesn't affect changes in another area. That's really the basic concept behind a content management system.

If you change the design, the database is unaffected and can still be used without modification; the programming isn't affected either. The same is true for all three elements. Changing one doesn't affect the other two. If all these weren't individual, you would need to build an entire new website every time there was a change. That would be very costly and very time consuming. There are four basic components to a content management system.

  1. Core programming - the common functions and files that every site needs to function at a minimal level.
  2. Data Base - The "file cabinet" of all information properly organized, sorted and tagged for easy retrieval.
  3. Theme (design) - The display of the information when it's pulled from the data base.
  4. Plugins - Additional programming that can be added to get extra functions that aren't part of the core. These can be turned on and off at will without affecting the core programming.

About WordPress

According to the WordPress Codex, "WordPress powers nearly a quarter of new sites today, is the content management system (CMS) of choice for more than two thirds of the top million sites making it the most popular on the web, and is trusted by content publishers both large and small including CNN and the NY Times. With more than 50 million sites globally and eight years of history."

The roots go back to 2001, but it made its first appearance in 2003. You can view it's history in the Codex on this page.

This is the official website responsible for all communication and resources related to WordPress. From this site you can download a copy, as well as search for free plugins and free themes. Access to the codex and and the WordPress Forum can be found here as well.

The WordPress Codex


We've mentioned it several times. This is the location of all documentation pertaining to WordPress. It is intended to be an encyclopedia of all WordPress knowledge. It is an "open wiki" which means that it is written by contributors. You can add to or modify wiki articles. You can read more about it here. If you want to contribute, start with this page.

Like most software, WordPress is distributed under a license, which means there are certain things that you are legally permitted (and not permitted) to do with WordPress software and source code. WordPress is distributed under a license called the GNU General Public License, a very popular license in the open source industry. If that doesn't ring a bell, read on.

About the GPL
gnuThe GNU General Public License, or GPL, is an open source license. Open source doesn't just mean that you can view the source code — it has political and philosophical implications as well. Open source, or "Free Software", means you are free to modify and redistribute the source code under certain conditions. Free doesn't refer to the price, it refers to freedom. The difference between the two meanings of free is often characterized as "Free as in speech vs. free as in beer." The GPL is free as in speech.

If you move your WordPress site, you may have trouble getting your pages to show correctly. Often this problem is caused by two WordPress settings: the Site URL and the Home URL.

These are normally easy to change by going to Dashboard > Settings > General settings page. But sometimes that's difficult to do because the move has broken your access to the WordPress administrator area.

Here's how to fix the problem.

There are some more complex alternatives to Widget Context and these include Widget Logic, Display Widgets and Slayers Custom Widgets.
