在此处将新闻模型更改为新闻模型
请在控制器中加载您的模型，其中使用
$this->load->model('News_model');
和使用
$this->News_model->set_news();
在create（）文件名：C:\xampp\htdocs\oproject\application\controllers\News.php行号：72 Backtrace:File:C:\xampp\htdocs\oproject\index.php行号：315 Function:require\u once`所以在News\u model文件中没有函数集\u News（），那么为什么在这里调用该函数呢？我想有一个：public Function set\u News（）方法在News\u模型中，，，您能检查一下吗？模型中没有set\u News（）函数，您将该函数放置在控制器中，请检查它
