当我要提交帖子时，会出现此类错误。我尝试更改从数据库字段到视图的所有内容，但是每次运行代码时，我都会遇到相同的错误，但看不到问题出在哪里
职位控制器

错误在第74行，错误消息：
调用未定义的方法CI_Loader :: libary（）
最佳答案
在构造函数中尝试
$this->load->library('upload');
更换线74
$this->upload->initialize($config);
$this->load->library('upload', $config);
请享用！我希望。会的。 :)
关于php - 调用未定义的方法CI_Loader::library()，我们在Stack Overflow上找到一个类似的问题：https://stackoverflow.com/questions/44191142/
