Filter the output of JSON

[zenliver]

Thank you for creating such an excellent wordpress REST API plugin, it enhances the output of JSON.This feature helps me a lot:

the official API:

/wp-json/wp/v2/posts?categories=5

this outputs only category 5's posts not including its children categories posts

and better-rest-endpoints API:

/wp-json/better-rest-endpoints/v1/posts?category=5

this outputs all posts of category 5 including all its children categories posts

appreciate for your excellent works!

Now I have a little suggestion about filtering the output of JSON.

Can we add a filter parameter to the API's endpoints to filter the output of JSON? For example:

if wen can use:

/wp-json/better-rest-endpoints/v1/posts?category=5&fields=id,title,date

(query string &fields=id,title,date is added)

to output only the id title date fields, thus the JSON output will be much smaller.

Many thanks! Wish you a happy life!

Hi @zenliver thanks for the issue. I think this could be a great idea. I might not be able to get to it for a little bit but I'll definitely take a look into how we could accomplish it. Feel free to make a PR if you have any ideas. I know that something like this might be coming to the official Rest API soon (https://core.trac.wordpress.org/ticket/43874)

@erwstout Thank you for your answer!

The json fields filtering of official API has been already resolved by an excellent plugin WP REST API - filter fields, but the official API still has something not good.
