php - After woocommerce/wordpress registration
803
Solution:
WordPress core handles user registration and runs the hook right after a user is registered.
Taking from the codex an example would be:
add_action( 'user_register', 'myplugin_registration_save', 10, 1 );
function myplugin_registration_save( $user_id ) {
if ( isset( $_POST['first_name'] ) )
update_user_meta($user_id, 'first_name', $_POST['first_name']);
}
