Working with Taxonomies by Hand // Statamic Docs

Creating Taxonomies

Taxonomies are kept in content/taxonomies, each with their own YAML file, and their entries in a matching subdirectory.

taxonomies/
|-- tags.yaml
|-- tags/
    |-- good.yaml
    |-- great.yaml
    |-- best.yaml

Each Taxonomy's YAML file can contain its title, as well as any data that should be injected into all its terms.

title: Tags
inject:
  foo: bar

A taxonomy (or multiple taxonomies) can be assigned to a collection.

# content/collections/blog.yaml
 
title: Blog
taxonomies:
  - tags

When editing an entry in that collection, taxonomy fields will be automatically added.

To taxonomize an entry, you can add term values to a field named exactly the same as the taxonomy's handle.

title: My Entry
tags:
  - foo
  - bar
  - baz

Now when listing entries that belong to the foo, bar, or baz terms, the entry will appear.

Hot Tip!

Make sure that the field is named exactly the same as the taxonomy handle, otherwise it will not be considered part of that taxonomy term.

Additional data (custom fields) can be added to a term by creating a yaml file matching the term’s slug.

site/content/taxonomies
|-- tags.yaml
`-- tags
    |-- foo.yaml
    `-- bar.yaml

In the YAML file, add data like so:

food: bacon
drink: whisky

Whenever referencing the Terms in your templates, now {{ food }} and {{ drink }} would output bacon and whiskey respectively.

Just like entries, these values will be augmented automatically in your templates depending on the blueprint.
