you need it name of file first then move to upload folder


        if (isset($_FILES['image'])) {

          
            $uploadFolder=ROOTPATH."upload";
                             
            $avatar = $this->request->getFile('image');
            $avatar->move($uploadFolder, time() . '.' . $avatar->getClientExtension());
            $pathStoreToDatabase= $avatar->getName();
            

        }

```
and remember use post method
