apply_filters_deprecated( string $tag, array $args, string $version, string $replacement = null, string $message = null )

Fires functions attached to a deprecated filter hook.

描述

When a filter hook is deprecated, the apply_filters() call is replaced with apply_filters_deprecated(), which triggers a deprecation notice and then fires the original filter hook.

Note: the value and extra arguments passed to the original apply_filters() call must be passed here to $args as an array. For example:

// Old filter.
return apply_filters( 'wpdocs_filter', $value, $extra_arg );

// Deprecated.
return apply_filters_deprecated( 'wpdocs_filter', array( $value, $extra_arg ), '4.9.0', 'wpdocs_new_filter' );
