rest_(post_type)_collection_params filter-hook . WC 1.0

Filter collection parameters for the posts controller.

The dynamic part of the filter $this->post_type refers to the post type slug for the controller.

This filter registers the collection parameter, but does not map the collection parameter to an internal WP_Query parameter. Use the rest_{$this->post_type}_query filter to set WP_Query parameters.


add_filter( 'rest_(post_type)_collection_params', 'filter_function_name_8422', 10, 2 );
function filter_function_name_8422( $query_params, $post_type ){
	// filter...

	return $query_params;
JSON Schema-formatted collection parameters.
Post type object.
