WordPress Hook After Options Page Save

April 28, 2016

If you want to hook into WordPress when an options page is saved and access the values that were entered, you can use update_option_{$option}.

Let’s say for my options page, I added the setting like this:

register_setting( km_my_cool_options, km_my_cool_options );

I could then hook into when the options page is saved and access the old & new values like this:

* Hook into options page after save.
public function km_hook_into_options_page_after_save( $old_value, $new_value ) {
if ( $old_value['some_option'] != $new_value['some_option'] ) {
// This value has been changed. Insert code here.
add_action( 'update_option_km_my_cool_options', 'km_hook_into_options_page_after_save', 10, 2 );
