You can't store the image in the way you used as:
$image = strtolower($this->input->post('image'));
Get the image file name once it is uploaded. Here is your modified code:
if (!$this->upload->do_upload('image')){
$this->form_validation->set_message('cat_image_upload', $this->upload->display_errors());
return false;
}
else{
$this->upload_data['file'] = $this->upload->data();
$data = array('upload_data' => $this->upload->data());
$doc_file_name = $data['upload_data']['file_name']; // Use this file name to store in database
return true;
}
