$visibility_trans = __('Public'); 

if ( 'private' == $post->post_status ) {
	$post->post_password = '';
	$visibility = 'private';
	$visibility_trans = __('Private');
} elseif ( !empty( $post->post_password ) ) {
	$visibility = 'password';
	$visibility_trans = __('Password protected');
} elseif ( $post_type == 'post' && is_sticky( $post->ID ) ) {
	$visibility = 'public';
	$visibility_trans = __('Public, Sticky');
} else {
	$visibility = 'public';
	$visibility_trans = __('Public');
}
