推荐答案

您的PHP更改

$this->upload->do_upload()

到

$this->upload->do_upload("add_1")

其中add_1是您的输入名称属性。

where "add_1" is your input name attribute.

代码UPLOAD库文档

PS在HTML中，=的Label属性定位输入ID，因此您必须在输入中添加ID。

P.S. At your HTML the Label attribute for="" is targeting input ID so you have to add id to your input.
