cakephp3为定义的变量提供未定义的错误

Question

我的代码是-

$user_id = 1;
$users = $this->UserModel->getUser($user_id);

$get_result = $this->Actionmodel->find('all', [
    'conditions' => ['id IN' => $ids],
    'contain' => [
        'Rank' => function ($q) {
            return $q
                ->select(['id', 'user_id', 'description'])
                ->where([
                    'status' => 1,
                    'user_id NOT IN' => $users
                ]);
        }
    ]
]);

给错误的未定义用户。 同时打印user_id数组。

您在闭包中使用$users ，但未指定use ...这样做：

$get_result = $this->Actionmodel->find('all',[
                                    'conditions'=>['id IN' => $ids],
                                    'contain'=>['Rank' => function ($q) use ($users) {
                                    return $q
                                    ->select(['id','user_id','description'])->where(['status' => 1,'user_id NOT IN' => $users]);}]]);
