_wp_register_meta_args_whitelist() │ WP 4.6.0

Deprecated from version 5.5.0. It is no longer supported and can be removed in future releases. Use _wp_register_meta_args_allowed_list(). Please consider writing more inclusive code instead.

Filters out register_meta() based on an allowed list.

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

Internal function — this function is designed to be used by the kernel itself. It is not recommended to use this function in your code.

No Hooks.

Return

Array. Filtered arguments.

Usage

_wp_register_meta_args_whitelist( $args, $default_args );
$args(array) (required)
Arguments from register_meta().
$default_args(array) (required)
Default arguments for register_meta().
