Removing Content From WP API Response When Listing Posts

October 25, 2016March 19, 2016 by Yoren Chang

For many reasons you might want to exclude certain fields from WP API response in certain circumstances. In this short post I’ll be showing you how to remove the “content” field from WP API response when visiting /wp/v2/posts route.

Getting Categories With Posts In A Single WP API Request

March 3, 2016December 18, 2015 by Yoren Chang

UPDATED March 03, 2016:

Post has been updated. Now we use "rest_prepare_category" filter for this job.

UPDATED March 02, 2016: 

With the latest WP API V2 Beta12, the filter "rest_prepare_term" I used in this post no longer work and it should be changed to "rest_prepare_category". I'll update the post content ASAP.

A while back ago I wrote a post to show you how to “Adding Fields To The JSON Response Of The WP REST API“. In the first scenario why we’ll ever need to add fields to WP API, is for people who want to build an accordion menu with categories as the first level links, which when being clicked, the posts would be collapsed as the second level links.

We know we could use WP API to get a single category info, and we can also get the posts for a certain category, but unfortunately we can’t do both in a single API request.

Display Post Excerpt To The More Tag With WP API V2

October 25, 2016December 12, 2015 by Yoren Chang

Ho Ho Ho! It’s December now so you get a Santa-style greeting from me! Today I’ll be showing you a simple trick that I got asked a while back ago in one of the comments, that is: “how can we display excerpt to the more tag (<!–more–>) with WP API V2”?

By default, WP API V2 has the excerpt field in the posts response, but the auto generated one is often not what we want.

So here are things we’d like to hack around the WP API and get the results we want:

Get the excerpt with read more link
Get the excerpt from text before the more tag
Display content of the shortcodes or oEmbed links in your excerpt

Now let’s get started.

Upgrading Your AngularJS Theme To Work With WP API V2

October 25, 2016September 29, 2015 by Yoren Chang

Note added 2015/12/16: Now this post is updated to be compatible with WP API v2 Beta 9.

Note added 15/12/13: With the BREAKING CHANGES in WP API v2 Beta 9, the theme is now broken even if you follow this tutorial. I'll manage to update the post soon so don't get too excited about the plugin updates.

Today in this post, I’ll be showing you how to upgrade the AngularJS WordPress theme that we have been working on for a very long time, to work with the latest WP API v2 (beta 4 at the time of this writing).

To be honest I didn’t expect the WP API v2 would be so much different from the version 1. When I talked about upgrading the theme in some comments of my tutorials, I thought it just about updating the routes and that’s all. It turned out I was wrong and the mistakes I’ve made are pretty worthy of documenting. So here we go.

Getting Posts By Taxonomy Or Meta Field With WP-API v2.0

October 25, 2016July 20, 2015 by Yoren Chang

Mar 03, 2016 UPDATED:

Updated all routes in this post so now should be compatible with WP API V2 beta 12.

Feb 28, 2016 UPDATED: 

Just realised since v2 beta 4, /posts WP_Query vars was moved back to filter param. I'll update all routes in this post ASAP.

In the post adding fields to the JSON response of the WP REST API, you’ve learned about how to manipulate the data from the WP REST API (WP-API). Another topic I got asked very often, is how to get posts by certain filters – mostly taxonomy and meta field. So today let’s talk about it.

Before we get started, if you’re looking for the workarounds for WP-API v1.x, Josh has written great tutorials for you. Here are the links of them:

In the following article, I’ll show you the quick answers and a more bigger picture beyond them. If you’re not interested in the later one, feel free to skip it.
