How do I create a "publish" button to put in a custom metabox?
Or if you can point me to the code that creates the current publish box, that'd help me out.
-attempting to simplify my custom post type-
All admin UI pages use a core function for a reason:
submit_button( $text = NULL, $type = 'primary', $name = 'submit', $wrap = true, $other_attributes = NULL );
get_submit_button() in case you want to return instead of print the button.
<button type="submit">Your Text</button> should about do it for you...it's just a submit button, nothing special. It's generated by
submit_button( __( 'Publish' ), 'primary', 'publish', false, array( 'tabindex' => '5', 'accesskey' => 'p' ) );.
