Custom Taxonomies

Posted on April 30th, 2011

While this new feature may seem a bit complex to non-developers, it certainly brings WordPress 3.0 closer to a true CMS.  Custom taxonomies allow you to create additional pieces of meta information.  By default, there are “Categories” and “Tags.”  Now we can add additional types, with the option of being hierarchical or not.

So what does this mean exactly?  Here are some examples of what you can do with custom taxonomies:

Let’s say you’re a film fanatic and you use your WordPress blog to post reviews and rate new movies.  You can create a custom taxonomy for “Rating,” then add R, PG-13, PG, G to every review.

Another example would be real estate listing websites.  In addition to photos and descriptions, you might use additional taxonomies to provide a list of specs on each property such as asking price, number of bedrooms, year built, etc.
