NOTE: This plugin was created to test a feature which has since landed in WordPress core. To request specific fields with your REST API response, you may use the _fields query parameter introduced in WordPress 4.9.
Usage:
| Example Query | Result |
|---|---|
/wp/v2/posts?_fields=id,title |
Return a posts collection where each post includes only the id property and title object. |
/wp/v2/media?_fields=source_url |
Return a media collection where each object includes only the source_url. |
/wp/v2/tags?_fields[]=slug&_fields[]=id |
Return tag objects with only the id and slug properties. |
As noted in the above examples, the core implementation supports using query parameter array syntax or a comma-separated list.
Legacy plugin README below, for posterity.
Specify fields for the response JSON. See https://core.trac.wordpress.org/ticket/38131.
Use by specifying the fields you want as part of the request as a comma delimited list: ?fields=title,excerpt.
