首先,使用$config2再次加载库将不起作用,因为库已加载一次,而$config1将保持加载状态。要加载新配置,请使用$this->upload->initialize($config2)代码>
其次,加载$config2将覆盖以前的配置。你应该重新安排你的代码。否则,两次上载将只使用最新的配置($config2)。例如:
使用$config1加载库
处理do_上传(“产品小图像”)并收集结果
使用initialize()加载$confg2
处理do_上传(“产品大图像”)并收集结果
处理结果(如果成功,则保存到db;如果其中一个上载失败,则显示错误)

下面是我为成功上传不同目录中的多个图像而编写的全部代码。再次感谢@Samutz
