Answer 1

您确定$ ccover变量已发送到php吗？

Answer 2

您无法在post元素中获取输入类型文件...为了获取文件名... codeigniter具有上载类的方法数据..您可以在其中获取文件名...因此为了上传文件

        if ( ! $this->upload->do_upload('ccover'))
        {
                print_r($this->upload->display_errors());
        }

do_upload方法强制您上传文件...，之后您可以获取文件名

更改

$ccover = $data_form['ccover'];

到

$ccover = $this->upload->data('file_name');

我的项目中codeigniter中的未定义索引
