How to use

Setting up the metabox in CMB2

Add the query_rest property to the field that you wish to query by in your CMB2 field configuration.

• If set to true, the field ID will used to query the REST API.
• If set to a value, the value will be used to query REST API.

Example

$cmb = new_cmb2_box( [
    'id'            => 'my_metabox',
    'title'         => __( 'My Metabox', 'cmb2' ),
    'object_types'  => [ 'post' ],
    'show_in_rest'  => WP_REST_Server::ALLMETHODS
] );

$cmb->add_field( [
    'id'            => 'my_text_field',
    'name'          => 'My text field',
    'type'          => 'text',
    'rest_query'    => true
] );

$cmb->add_field( [
    'id'            => 'custom_query_name',
    'name'          => 'My text field',
    'type'          => 'text',
    'rest_query'    => 'my_query'
] );

Querying the REST API

For each field that has rest_query set, 3 parameters will be available in the REST request on each post type that this field's metabox is registered on:

• the field's rest_query value or id (as defined above)
• the above parameter appended with _compare
• the above parameter appended with _type

Adding the field's query parameter to the request will add that field to the request's meta query. By default compare will be '=' but using the {rest_query}_compare parameter, this can be changed to any option allowed by WP_Meta_Query. The type of the query parameter will be set to 'CHAR' by default but this can be overwritten using {rest_query}_type, again with the values allowd in WP_Meta_Query.

Following the above example a query could look like:

const request = new Request('https://wordpress.org/wp-json/wp/v2/posts?my_text_field=hello&my_query=world&my_query_compare=LIKE');
