File Upload Validation Broke

You know what, I got validation to work...still without JavaScript though - I don't have any progress showing things made, to test with.

PHP Code:

public function testing_uploads_validation()
    {
        $validation = \Config\Services::validation();
        $validation->setRule('img_path', 'Upload file', 'uploaded[img_path]|max_size[img_path,1000]|ext_in[img_path,jpg]');

        if($this->request->getPost('save')) {

            $validation->withRequest($this->request)->run();

            if(empty($validation->getErrors())) {
                $file = $this->request->getFile('img_path');
                if ($file->isValid() && !$file->hasMoved())
                {
                    $random = $file->getRandomName();
                    $file->move(WRITEPATH.'uploads', $random);
                }
            }
        }

        echo $validation->listErrors() ?? null;

        helper('form');
        echo form_open_multipart();
        echo form_label('Upload file', 'img_path');
        echo form_upload('img_path', set_value('img_path'), 'id="img_path"');
        echo form_submit('save', 'Save the file');
        echo form_close();
    } 


You can see things I made with codeigniter here: itart.pro its not overly impressive as I have very little time to learn.
