Answer 1

我认为文件输入名称应该是“ userfile”，而不是“ image”。

Answer 2

CI file upload file control default name is userfile .

If you want to change the it's name to customized one, then you have to pass the new name to upload function like :

  if ( ! $this->upload->do_upload("image")) // image is your new name for file control

Answer 3

Firstly,

either change the do_upload function call to:

if ( ! $this->upload->do_upload('image'))

OR

change the input name to this:

<input type="file" class="input-large" name="userfile" id="image">

Secondly,

change your form enctype to:

enctype="multipart/form-data"
