Design and Prototyping for Drupal

Step 1: Create the “Event Categories” Taxonomy Vocabulary

Taxonomy, for those who haven’t learned a lot of DrupalSpeak™, is how Drupal categorizes content. Each taxonomy vocabulary is a set of categories, or tags, that you can apply to one or several types of content. In previous versions of Drupal, you could create vocabularies as you needed them, by creating a vocabulary and selecting which content types the vocabulary could be associated with. This was easier in some respects, but could turn complicated as new content types were added.

In Drupal 7, taxonomy vocabularies are treated very differently. Rather than creating the vocabulary after the content type, you create it before you create the fields for a content type, and then add a “term reference” field that points back to the vocabulary within your content type.

We’ll start by creating a vocabulary. In the administration panel, we choose Structure→Taxonomy, and select the Add vocabulary option (see Figure 12-3). We’ll name our new vocabulary “Event Categories” and hit Save.

Once we’ve created our vocabulary, we’ll add terms by clicking the add terms link. Once you’re done adding terms, you can choose list terms to see the terms you’ve created. ...
