I don’t think there is a need to add the items to the init hook from the activation function. I think you can call them directly:
private static function single_activate() {
self::add_partner_terms(); //$this->add_partner_terms();
self::add_geo_terms(); //$this->add_geo_terms();
}
I’m not really sure if it should be self::
or $this->
because I’m a little bit fuzzy about OOP, especially tonight.
