Creating a theme: first steps To create a theme, we will do the following: 1. Create a directory for the theme. 2. Create the theme's .info (dot-info) file. 3. Add our first files. [ 45 ] Chapter 2 After we've finished these three short steps, we will add our JavaScript to the theme. A precaution for theme developers To get build our theme correctly, we will need to be able to view it. But to view it, we will need to have it enabled. What if we make a mistake that prevents Drupal from rendering correctly? We could lock ourselves out of the administration page. To prevent this from happening, it is wise to set the administration theme to one of the default themes. This is done in Administer | Site configuration | Administration theme. Creating a theme directory Every theme should have its own directory. When you install Drupal, one of the directories created is called themes/. If you take a look inside that directory, you will see all of the top-level (non-subtheme) themes that Drupal provides. Do not put your themes in there. This directory is only for themes that come with Drupal's core. Themes, like modules, go inside the sites/ subtree. The sites/ area also appears inside the Drupal directory and is created when you install Drupal. Inside the sites/ directory, two folders are created by default: sites/all/ and sites/default/. To better understand these two directories, keep in mind that one installation of Drupal can serve multiple sites. For example, if I have a site called example.com and a site called anotherexample.com, I can use one installation of Drupal to serve both. The first site I install will be installed in sites/default/. The next site I install will need to go in its own folder (for example, sites/anotherexample.com/). Content that only belongs to a single site should go in that site's directory. For example, if I want to install a special theme for anotherexample.com, I should put the theme in sites/anotherexample.com/themes/.

Working with JavaScript in Drupal In other cases, I may want to share a theme or module across all sites. In these cases, files would go in sites/all/. In this book, we will be putting all of our themes and modules in sites/all/themes/ and sites/all/modules/. If in doubt, put files in sites/all/. This makes it easier to share your work between sites. With that background material behind us, let's create our theme directory. The name we give to this directory will be the name of our theme. Theme and module names should always be in a lower case, and may be composed only of letters, numbers, and underscores. In the .info file, we will be able to attach a human-readable name to the theme. That may use spaces, capital letters, and other special characters. Our first theme will be in sites/all/themes/frobnitz/ as seen in the following screehshot:. If this is the first theme you create, you may also need to create the sites/all/ themes/ directory. Once the directory is created, we need to add a special file to tell Drupal about the theme.
