临时工不工作。即使我省略了标题字段，它仍然会提交帖子。有什么想法吗？我只想验证每个字段，如果它是空的，您将收到一条消息（“请填写…”）然后返回页面，不发布任何内容。

你错过了wp_nonce_field 操作名称。
wp_nonce_field(\'submit-users-note\'\'notes_nonce_field\' );
$nonce = $_POST["notes_nonce_field"];
if ( ! isset($nonce) ! wp_verify_nonce( $nonce, \'submit-users-note\' ) ) {
exit; // Get out of here, the nonce is rotten!
}
