Then add uploader, which extends yiicod\fileupload\base\UploaderInterface and provides functionality to handle uploaded file

class UserAvatar implement UploaderInterface {
    /**
     * Event for coco uploader
     * @param string $fullFileName Full file path
     * @param Array $userdata Userdata from widget
     * @param Array $results Uploaded result file
     * @return Array or null
     */
    public function uploading($fullFileName, $userdata, $results)
    {  
        $model = new UserModel();
        //Save to temp
        $model->onAfterFileUploaded($fullFileName, 'logo');
    
        //After save requered set
        if ($model->save()) {
                return [
                    'url' => $model->getFileSrc('logo'),        
                    '...' => '...'
                ];
            )else{
                //Delete temp uploaded file
                $model->resetFile('logo');
                return [
                    'error' => 'Insert error message'
                    '...' => '...'
                ];
            };
        }
    }
}

Upload on submit

class UserAvatar implement UploaderInterface{
    
    /**
     * Event for coco uploader
     * @param string $fullFileName Full file path
     * @param Array $userdata Userdata from widget
     * @param Array $results Uploaded result file
     * @return Array or null
     */
    public function uploading($fullFileName, $userdata, $results)
    { 
        $model = new UserModel();
        //Save to temp
        $model->onAfterFileUploaded($fullFileName, 'logo');
    }
}
