Filters the default value for the option.
For settings which register a default setting in `register_setting()`, this
function is added as a filter to `default_option_{$option}`.
function filter_default_option( $default, $option, $passed_default ) { if ( $passed_default ) { return $default; } $registered = get_registered_settings(); if ( empty( $registered[ $option ] ) ) { return $default; } return $registered[ $option ]['default']; }
