Allow settings option schema to be modified

[pcfreak30]

In WP_REST_Settings_Controller,

get_registered_options

and

get_item_schema

Seem to pull/manipulate data from

get_registered_settings

, but don't have filters and/or register_setting does not allow a schema for the option value.

The use case is storing an associative array/hash of settings data in one option, to keep the options table tidy.

I think the best route possibly may be for

register_settings

to allow a schema in the

$args

and that get used in the controller for validation. Another way maybe just a filter to inject the needed schema on the fly, but that's less than ideal for the use case of verifying children items inside an options data.

Hi @pcfreak30!

Setting a custom schema is supported under the show_in_rest argument.

register_setting('name', 'group', [
    'show_in_rest' => [
        'schema' => [
            'type'       => 'object',
            'properties' => [
                'propA' => [
                    'type' => 'string',
                ]
            ]
        ]
    ]
]);
