Pretty much have mine working again now, I don’t know how hacky this is, but it works for now. If anyone from the REST API team read this then a little tutorial covering the do’s and don’ts would be great, especially for tax and meta queries 🙂

I am using woocommerce and filtering products so what I need will differ to you but basically I had to first register the _price meta_key so that products could be properly ordered:

$args = array(
    'type' => 'float',
    'description' => 'Product price for woocommerce products',
    'single' => false,
    'show_in_rest' => true,
);
register_meta( 'product', '_price', $args );

I also had to modify the existing order and orderby collection parameters for the product post type to accept new values:

add_filter( 'rest_product_collection_params', 'swish_rest_product_collection_params', 10, 2);

function swish_rest_product_collection_params($params, $post_type_obj) {
	$params['order'] = array(
		'description'        => __( 'Order sort attribute ascending or descending.' ),
		'type'               => 'string',
		'default'            => 'desc',
		'enum'               => array( 'asc', 'desc', 'ASC', 'DESC' ),
	);

	$params['orderby'] = array(
		'description'        => __( 'Sort collection by object attribute.' ),
		'type'               => 'string',
		'default'            => 'date',
		'enum'               => array(
			'date',
			'relevance',
			'id',
			'include',
			'title',
			'slug',
			'meta_value_num',
			'menu_order title',
			'menu_order',
			'data'
		),
	);

	return $params;
}

Finally I replaced my original rest_query_vars filter with this:

add_filter( 'rest_product_query', 'swish_rest_product_query' ,10 ,2 );
function swish_rest_product_query( $args, $request ) {
    $args['meta_query'] = array(
    		'compare' => 'IN',
    		'key'		=> '_visibility',
    		'value'		=>array('visible', 'catalog')
    	);
    if(isset($request['filter']['tax_query'])) {
    	$tax_query = array();
    	foreach ($request['filter']['tax_query'] as $query) {
    		$tax_query[] =array(
    			'taxonomy' 	=> $query['taxonomy'],
    			'field'		=> $query['field'],
    			'terms'		=> $query['terms'],
    			'operator'	=> $query['operator']
    		);
    	}
	    $args['tax_query'] = $tax_query;
    }
    if(isset($request['filter']['product_cat'])) {
    	$args['product_cat'] = $request['filter']['product_cat'];
    }
    if(isset($request['filter']['meta_key'])) {
    	$args['meta_key'] = $request['filter']['meta_key'];
    }

    return $args;
}

Your needs will differ but start with rest_{your_custom_post}_query, and build your standard wp_query with that by adding to the args, using the request object to grab the values as necessary.

Hi, I’d just like to raise this again as I can’t see the availability of the company name when exporting orders. I can see it for the customer export but not the order export. It’s also not shown as part of the pro version. Can you confirm?

Thanks.
