IF语句对true变量执行else，对于false变量CAKEPHP执行true

Question

为真，我收到“成功UNENLISTED（1）！”否则，我收到“成功登录（1）！”。

dump（$ swap）将返回true并仍然执行IF，否则，如果返回false则仍然执行true

我不了解CakePHP特有的内容吗？

//to grab database entry
public function swapSub($user_id_main, $user_id_from) {
        $result = $this->find()
                ->where(['Enlist.user_id_main'=>$user_id_main,'Enlist.user_id_for'=>$user_id_from])
                ->first();
                dump($result);
        if($result['active']){
            $result['active'] = 0;
            if($this->save($result)){
                return false;
            }
        } else {
            $result['active'] = 1;
            if($this->save($result)){
                return true;
            }
        }
    }

//display true and false statement. //$swap == TRUE/does not work either
            $swap = $this->Enlist->swapSub($user_id_main, $user_id_from);
            dump($swap);
            if($swap){
                $this->Flash->success(__('Successfully ENLISTED(1)!'));
            } else {
                $this->Flash->success(__('Successfully UNENLISTED(1)!'));
            }
