注意消息:尝试获取非对象文件名的属性:views/survay_view.php行号:33

收到上述错误的原因是,您试图访问$records数组中作为对象$row->some_变量保存的数据,而该数据似乎不是对象

您正在使用以下代码从数据库中获取结果:

$data['records']=$this->db->get'save\u survay',$config['per\u page'],$this->uri->segment2,0

上面的代码在数据库上运行一个查询,但这本身并不能生成任何有用格式的结果。它返回的是一个数组,包含与查询有关的各种数据,其中包含结果

要作为对象访问结果,可以按如下方式调整代码:

$data['records']=$this->db->get'save_survay',$config['per_page'],$this->uri->segment2,0->result

如果希望将结果作为数组返回,可以使用以下命令:

$data['records']=$this->db->get'save\u survay',$config['per\u page'],$this->uri->segment2,0->result\u数组


正如我在评论中提到的,我真的建议阅读文档,特别是关于

的页面,你能发布你的代码片段吗?我一直收到一个错误,说遇到了PHP错误严重性:注意消息:试图获取非对象文件名的属性:views/survay_view.PHP行号:33上面的代码有几个问题。首先,您的数据库代码$this->db->get位于控制器中。为了遵守MVC编程方法,应该将此代码放在模型中。它不会破坏您的代码,但会帮助您分离代码并使其更易于管理。出现上述错误的问题是,您需要使用$this->db->get->result返回一个results对象。我建议您阅读codeigniter文档,特别是这一页:该文档有多种语言可供使用,您可以详细介绍这些错误吗?非常感谢你的帮助,你让我免于了很多麻烦:我现在正在阅读这份文件
