推荐答案

请按照以下步骤操作

1. check $application_insert variable return anything?

2. change './application/assets/images/user_image/' to "application/assets/images/user_image/"

3. make writable all the folders assests, images and user_image

4. check spelling of the folders are same what you given in the upload path
