Create Dashboard Widget with form to keep team’s record

Here is a tutorial on submitting forms through dashboard widgets : http://www.wpexplorer.com/configurable-dashboard-widgets/

In the tutorial the author uses a single function for both displaying and updating the widget. What if you then use this approach and implement functionality similar to a save routine for custom meta boxes and custom fields to link the new meta data to a post/page id?

Could you try to add meta to a post/page or update existing meta of a post/page

add_post_meta( $post_id, $meta_key, $new_meta_value, true );
update_post_meta( $post_id, $meta_key, $new_meta_value );

I also noticed that he doesn’t have the entire form markup present in his example so your form action could then be left blank

Hope it helps and that I’m not way off with what your trying to do.
