I have follow code from this link, https://gist.github.com/757903 and I have manage to create several metaboxes on my custom options page under Settings section. Stuff that doesn't work for me are :
- I can't make it work, so save form work, I think that this hook doesn't exists "add_action('admin_post_save_howto_metaboxes_general', array(&$this, 'on_save_changes'));"
- When I move boxes around, next time when I come back to that page, order of meta boxes is not saved, same thing for columns layout.
Can someone help me with this please. Thank you in advance.
