不太可能，但可以尝试以下方式：

add_action(\'wp\', \'check_post_pass\');

function check_post_pass(){

  if(!is_single() || !post_password_required()) return;

  global $post;
  if(isset($_COOKIE[\'wp-postpass_\'.COOKIEHASH])
      && $_COOKIE[\'wp-postpass_\'.COOKIEHASH] !== $post->post_password){

    define(\'INVALID_POST_PASS\', true);

    // tell the browser to remove the cookie so the message doesn\'t show up every time
    setcookie(\'wp-postpass_\'.COOKIEHASH, NULL, -1, COOKIEPATH);
  }

}   

if(defined(\'INVALID_POST_PASS\')) _e(\'The password you entered is funky\');
