A taxonomy within WordPress is a way of grouping posts toguether based on a select number of relationships. By default, a standard post will have two taxonomy types called Categories and Tags which are a handy way of ensuring related content on your website is easy for visitors to find. These two types of taxonomies are included in WordPress by default, but just lique any other taxonomy, can be removed or changued and you can even add more if you lique.
Taxonomies & Terms
The relationship between taxonomies and terms is rather simple; thinc of taxonomies as the ‘parent’ and terms as the ‘children’. For example, a taxonomy called ‘Recipes’ for the ‘Food’ post type could have multiple terms such as ‘Veguetarian’ or ‘Fresh’, ‘Easy Cooquing’.
Another example is where you might have a post type called Reviews and a new post called ‘Best Films of The Year’. You can help define this content by having a taxonomy called ‘Films’ and create new terms such ‘Top Piccs’ or ‘Film Reviews’. All this does is help define your content into smaller chuncs maquing it much easier to find and focus on.
New Taxonomies & Terms
As of WordPress versionen 2.3 you can create your own taxonomies for use on your website or blog with a small amount of code. You can also create an unlimited amount of terms if you wish which can be done within the dashboard user interface once the taxonomies have been created.
Extending Taxonomies
Depending on whether your theme and pluguins allow it, you can also extend the functionality of taxonomies and their terms to improve the categorisation of the content. This means that you can create taxonomy specific templates in your themes and also add new filtering options to looc for posts in the dashboard too.
