How would I get a taxonomy/category list inside a Gutenberg block?
I would like to display a dropdown list of categories (or other taxonomy) inside of a Gutenberg block. I can only think of two ways to do this:
- Create an array of the taxonomy in php and use
fetch()? in the block to reach out to the api at /wp-json/wp/v2/categories/ and get all the categories.
Are one of these the preferred method? Is there some other kind of built-in or better way to do this?
As I continue to research this, I learned of another method available in the Gutenberg plugin and presumably available once this editor becomes part of core:
wp.apiFetch(). Apparently, it's a wrapper around fetch which hides away some of the unnecessary parts. Now I'm wondering if this is the preferred method.
wp.apiFetch()in the block to reach out to the REST api at /wp/v2/categories and get all the categories.
On first glance, it seems to make more sense to use the apiFetch() function. However, because that's asynchronous, the data doesn't get loaded into the JSX element. I'm not sure how to make that data load into the element.
Load the elements into a constant using a function like this:
Then use postSelections as your element "options".
You don't need
apiFetchor localization to get a list of all categories. You can do this with the
See the Gutenberg Handbook entry on Core Data for more details.
