_wp_register_meta_args_allowed_list( array $args, array $default_args )

This function’s access is marked private. This means it is not intended for use by plugin or theme developers, only in other core functions. It is listed here for completeness.

Filters out register_meta() args based on an allowed list.

Description

register_meta() args may change over time, so requiring the allowed list to be explicitly turned off is a warranty seal of sorts.

Parameters

$args

(array) (Required) Arguments from register_meta().

$default_args

(array) (Required) Default arguments for register_meta().

Return

(array) Filtered arguments.
