A relatively new feature of Joomla! is the ability to display the same module in multiple positions, and varying it depending on which page you are looking at. For example, you might want to display the search module in the header position on home page, but you want it in the left position on each sub page. Here is a quick and easy way to accomplish this.

Joomla! has a problem that you may or may not know about. It is a minor problem (or major, depending on whom you ask), and it will not really affect how your website functions.

The problem exists in how Joomla! renders menus. By default, the main element that contains the menu (in the case of a "flat list" menu, it is the "ul" element) is given an id=mainlevel. This is not a problem if you are using one menu on a page. But, if you are using multiple menus on a single page, there is a conflict.

Proper XHTML markup should not have more than one element with the same id. An id should be unique for each element that is given an id, so the browser can tell them apart for the purpose of style sheets and javascript. If you use multiple menus on the same page, you are using improper XHTML markup, and you will fail XHTML validation.

You can rest easy, though, because there is a solution. Read on to find out what it is.

You've installed Joomla!, installed all of the components, modules, and mambots you need, and you've created your content and menus. Now you want to create a custom look for your Joomla! site, but you don't know how to create a template. This article will step through the creation of a very basic template in Joomla! Hopefully, by the end of this article, you will have a basic understanding of what goes into a Joomla! template. (Note: This information only applies to Joomla! 1.0.X. It does not apply to version 1.5.)

By default, Joomla! displays the FrontPage component on the home page. The FrontPage component takes a list of content items that are published to the FrontPage and displays them in a blog layout. This will work for most sites, but some webmasters want the option to display something else on the home page. If you would like to change what is displayed on your home page, follow these steps:

1. In your administrator panel, click Menu->mainmenu.
2. Create a new menu item that links to what you want to display on the home page.
3. Re-order your menu items such that the item you want to display on the home page is listed first.

It really is that easy. Joomla! displays the first menu item in mainmenu as the home page. You can set anyting in your site as your home page using this method.

I had a request from a reader to provide more detailed instructions on "database wrangling" with your Joomla! database. This article is an attempt at honoring that request. I will add an article later that explains how to import your Joomla! database using phpMyAdmin.

To perform the tasks in this article, you will need phpMyAdmin installed on your server. I am using version 2.8.0.2 of phpMyAdmin and version 4.1.21 of MySQL. For the sake of brevity, I have assumed that you have access to your MySQL server and left out details on how to gain that access. If you are unsure about how to gain access to your MySQL server, you should contact your hosting provider.

Update February 7, 2009: I have now written an an article on how to move your Joomla! 1.5 site to a new server.

Things happen. Plans change. Websites outgrow current servers and need new servers. Hosting companies provide poor service, prompting a web master to decide to change servers. Whatever the reason, you might need to move your Joomla! installation from one server to another.

If you've been running a website for a while, you have probably already accumulated quite a bit of content and several 3rd party components and/or modules, and you do not want to start fresh with a new Joomla! installation. This article explains what I did to move HowToJoomla from my test server (howtojoomla.corywebb.com) to the server that it is on now.

I just recently installed Joomla! using a database that already had an instance of Joomla! installed in it. It was actually really easy. This article explains how to install multiple instances of Joomla! with 1 database.

With your standard Joomla! installation, you get a WYSIWYG editor called TinyMCE. A WYSIWYG (What you see is what you get) editor basically enables you to edit content items in your browser just like editing a document in a word processor without needing to know how to write HTML code.

For most people, TinyMCE will serve their needs adequately. However, you might prefer to use a different editor. If so, this article will teach you how to install a new editor and make it your default editor.
