failed to upload image file and save data

@ the prodigy,

sir, in our Upload.php in the Libraries shows this script in the data().

Code:

$file_data = $this->upload->data();

this script calls this in the Upload.php

Code:

function data()
    {
        return array (
                        'file_name'            => $this->file_name,
                        'file_type'            => $this->file_type,
                        'file_path'            => $this->upload_path,
                        'full_path'            => $this->upload_path.$this->file_name,
                        'raw_name'            => str_replace($this->file_ext, '', $this->file_name),
                        'orig_name'            => $this->orig_name,
                        'file_ext'            => $this->file_ext,
                        'file_size'            => $this->file_size,
                        'is_image'            => $this->is_image(),
                        'image_width'        => $this->image_width,
                        'image_height'        => $this->image_height,
                        'image_type'        => $this->image_type,
                        'image_size_str'    => $this->image_size_str,
                    );
    }
