Как сделать так что бы пользователь который добавил данные, только он мог изменять эти данные?

 
<?php
class modelStreetball extends cmsModel {
	public function addBattle($battle){	
		return $this->insert('photobattles', $battle);		
	}	
	public function updateBattle($id, $battle){	
		return $this->update('photobattles', $id, $battle);	
	}
	public function deleteBattle($id){	
		$config = cmsConfig::getInstance();	
		$battle = $this->getBattle($id);	
		$logos = self::yamlToArray($battle['logo']);
		if (is_array($logos)){
			foreach($logos as $path){
				unlink( $config->upload_path . $path);
			}			
		}				
	return $this->delete('photobattles', $id);		
	}
	public function getBattle($id){	
		return $this->getItemById('photobattles', $id);	
	}
	public function getBattles(){
		return $this->get('photobattles');		
	}	
	public function getBattlesCount(){
 
		return $this->getCount('photobattles');
	}
}

 
<?php
