Drupal is a free, open-source content management system (CMS) for a variety of platforms. It has a robust user community and easy-to-use administration features. Drupal Essential Training covers all the important aspects of installing, configuring, customizing, and maintaining a Drupal-powered website. Instructor Tom Geller explores blogs, discussion forums, member profiles, and other features while demonstrating the steps required to make Drupal perform. He also teaches fundamental concepts and skills along the way, including installation, backups, and updates; security and permissions; flexible page layouts and CSS; menu navigation; and performance monitoring and disaster recovery. He also discusses how to select and install the community-supported modules that further expand Drupal's capabilities, and gives experienced PHP programmers tips on customizing page templates. Example files accompany the course.
So now your Drupal site is up and humming smoothly, but it still looks rather generic. In Drupal, presentation is controlled by a system of page templates, which collectively is known as themes. So all we need to do to change the entire site's appearance is to change its theme. Fortunately, that's easy to do in Drupal. Just as a reminder, none of the site's content will change in this process. That means you can switch back and forth among many different themes without losing your articles, graphics, users or site information. There are literally hundreds of themes available online with a variety of looks and for a variety of purposes. For example, to make your site look good on mobile phones, we will look at some of those in another video, but for now, let's stick the six that come with Drupal 6.3's default installation.
I will show you how to change the default theme, that is, how the site looks to every casual visitor before they become a member as well as how to let your site's registered users select a different look that they like better. The first place that we go is over to Administer and then down to Themes. Here we see a list of themes that are available. By default, Garland is the theme. But we can change that by clicking in Default on any of these other ones. We will do that now and change the theme to Bluemarine. Scroll down to the bottom and Save Configuration. There, the entire look of the site has changed. One other thing has changed by the way, the Enabled box is now checked because obviously if this is the Default theme, it has to be enabled first. I am going to change it back to Garland now, Save configuration, and we are back at Garland, but notice the Enabled box is still checked. There are a few things that carry over when you go from theme to theme and some things that don't. For example, we have up here, 'Where damp basements are a feature not a bug.' That was something entered in site information as, I believe, the slogan.
Let's switch to Chameleon, for example, Save that configuration and that slogan has disappeared. We can make it reappear by enabling it in this specific theme or by making this slogan appear in every theme. Let's just do it for this one. We click on Configure and we get many different options, one of them being, whether or not the site slogan shows up. Let's try clicking on that, go down, Save Configuration, boom, there it is, it now shows up. If we want to change what shows up in every theme, we can go to Global settings and then when we click Site slogan, and say Save configuration, no matter what theme we go to now, the site slogan will show up. If for example, we were to go to Marvin, the site slogan now shows up. Let's go back to our original theme, which was Garland. In the process, we have enabled four themes.
I will show you how to make those themes available to each registered user now. First, we have to give them that permission by going to Administer, scroll down to Permissions and then scroll down to select different theme. Authenticated users are those who have become members of your site. Anonymous users are those who haven't. So we will say yes only to those people who have become members to the site, Save permissions. Now any user who goes to their local My account page over here and clicks on Edit, will be able to change the theme that they see. For example, this user wants to see Bluemarine, Save and, boom! That didn't change the theme for anybody else, only for this user. We are going to change back to Garland. Go back into themes and clean up what we did, just to make it clean. Garland becomes the Default theme, Save the configuration and we are done.
So here we have talked about how to move from theme to theme and how to change some of the things that show up within a theme such as slogans and mission statements. There are hundreds of themes out there though, so you can do more than just switch among them. You can change the way that the typography looks, the graphics in them and the way that they behave by editing them.
