I try to save with wp-json my custom post types meta data but does not works in my case
I create my custom post type with jjgrainger's class as it follows
$arguments = array(
'public' => true,
'show_in_rest' => true,
);
$survey = new PostType('survey', $arguments);
$survey->register();
register_meta( 'survey', 'survey_data', array(
'show_in_rest' => true,
'single' => true
) );
return $survey;
but when I save the following structure
post: {
title: "Title",
content: "some content",
status: 'publish',
id: null,
survey_data: null,
meta: {
survey_data: [{'some': 'asdasd'}, {'some':'ssdfs'}]
}
},
the post will be created but not the meta data

Reset to default 0The register_meta() function is defined like so:
function register_meta( $object_type, $meta_key, $args, $deprecated = null )
And the $object_type (as of now) has to be post for all post types. So use this:
register_meta( 'post', 'survey_data', ... )
See the // {comments} in the code below, which I copied from here:
<?php
// The object type. For custom post types, this is 'post';
// for custom comment types, this is 'comment'. For user meta,
// this is 'user'.
$object_type = 'post';
$args1 = array( ... );
register_meta( $object_type, 'my_meta_key', $args1 );
UPDATE
If you'd like to limit the meta to a certain post type, use the object_subtype parameter like so: (that parameter was added in WordPress version 4.9.8)
// Add survey_data meta support to `survey` post type in REST API.
register_meta( 'post', 'survey_data', array(
'show_in_rest' => true,
'object_subtype' => 'survey',
...
) );
// Add survey_data meta support to `my_cpt` post type in REST API.
register_meta( 'post', 'survey_data', array(
'show_in_rest' => true,
'object_subtype' => 'my_cpt',
...
) );
And as you can see, just duplicate the same register_meta() call for other post types. But the $object_type needs to be post, even for Pages (page post type).
