您可以这样做：

function wpse_113057_hide_publish_buttons(){
 $cpt = \'your_post_type\';// can be post
 global $post;
 if($post->post_type == $cpt && current_user_can(\'members\') ){
  echo \'
    <style type="text/css">
      .misc-pub-section, #delete-action {
        display:none;
      }
    </style>
  \';
 }
}
add_action(\'admin_head-post.php\', \'wpse_113057_hide_publish_buttons\');
add_action(\'admin_head-post-new.php\', \'wpse_113057_hide_publish_buttons\');

希望这有帮助。
