Php Codeigniter用户会话错误

我在Codeigniter框架中面临一个新问题。她是我最讨厌的人

如果对

登录

变量执行

var\u转储

，您将看到它是一个数组，而不是一个对象，因此无法像处理对象一样处理它

 //You used this code because row_array return array not object
 `$`login["result"] = `$`this->Customer_model->login(`$`email, `$`password, `$`remember);
  echo  $login['result']["last_name"];

因此，请转到您的模型并修改以下内容：

$customer = $result->row_array();

将是：

$customer['result'] = $result->row_array();

然后在第46行中，将其用作：

$login['result']->last_name;

发生这种情况的原因：

因为正如您最初定义的那样，

$customer

是一个对象。稍后，您还通过使用

$customer['something']

分配模式，将其重新定义为一个数组。

所以你不能随心所欲，它要么是数组，要么是对象。

问题是什么？返回tics用于什么？遇到了一个PHP错误严重性：注意消息：尝试获取非对象文件名的属性：controllers/secure.PHP行号：46 abida SultanaSearch并删除这些返回标记以开始<代码>$电子邮件应为$email.echo“pre>----

消息：尝试获取非对象的属性
，这与错误不同。新错误现在显示
未定义属性：stdClass:：$last\u name
。这意味着没有从数据库中提取姓氏。@易卜拉欣-只需确保从数据库中获取姓氏即可
 //You used this code because row_array return array not object
 `$`login["result"] = `$`this->Customer_model->login(`$`email, `$`password, `$`remember);
  echo  $login['result']["last_name"];
