这是代码，错误来自哪里 :) 我希望我能尽快得到答案！！！

“试图获得非对象的财产”的通知再清楚不过了。您正在尝试读取不是对象的东西的属性。

例如：

$object = false;
echo $object->property; // Notice: Trying to get property of non-object

可能它正在发生，因为您假设您正在执行的每个 SQL 查询都是成功的。但是，如果 SQL 查询出现错误并且无法运行，则调用将返回false而不是返回结果对象。

Sinse你甚至没有说你遇到这个问题的线路是不值得在这里进一步帮助你的努力。在尝试使用结果之前检查您的查询是否成功，并从中读取 MySQL 错误消息$this->db->error以找出问题所在。
