Joomla 1.5 Custom Breadcrumbs

Garrett Bluma — Thu, 09 Jul 2009 06:00:00 +0100

Joomla seems to have everything figured out — Breadcrumb support is no exception.

Recently we were writing some custom component for a client and needed to handle the breadcrumbs in a special way that Joomla couldn't manage automatically.

As a simplified example, imagine we redirect a user to a component that isn't attached to a menu. We would expect the breadcrumbs to simply output "Home" and provide a link back to the index of the site.

Trevor M. — Tue, 19 May 2009 06:00:00 +0100

Embedding videos inside your Joomla content is easy. There are several Joomla plugins that make it a snap.

Once you have installed the plugin, you will need to enable it by going to the "Plugin Manager" in the backend of your Joomla site (/administrator).

Turn on Caching to Speed Up Your Joomla Site

Trevor M. — Fri, 27 Feb 2009 07:00:00 +0100

There is a simple and effective way to help speed up your Joomla site. It is called "caching". When you use the caching feature, Joomla creates a static file (or cache), of your web pages. This means that your website can use this cached file instead of making redundant database calls each time someone goes to a page. This in turn saves time and speeds up your site.

Log into the back of your Joomla site (/administrator) to turn caching on. Go to "Global Configuration" as seen below.
