I'm trying to pass a nonce at the links created from my plugin using
Of course this is invalid:
add_submenu_page( 'my_dashboard', 'Dashboard', 'Dashboard', 'manage_options', 'my_dashboard&nonce-field=' . wp_create_nonce('my_action'), 'show_dashboard' );
as per the Codex, the slug should only include lowercase alphanumeric, dashes, and underscores characters.
So my question is, how could we pass nonce in the URL of the menu links a plugin creates?
