回复讨论(解决方案)

$post['txt_Name'] = $tel;
$tel在哪里定义的？你的框架是直接post后就可以使用该变量了么？

$post = $this->input->post(NULL, TRUE);
打印￥post的值是什么

$post['txt_Name'] = $tel;

	public function _FeedBack(){$post = $this->input->post(NULL, TRUE);if(isset($post['btnSubmit'])){ $post['addtime'] = time(); $this->message->insert($post);}}
