cakephp 3.8在数据库中存储ajax数据

Question

我正在尝试将Ajax数据存储到cakephp 3.8中的数据库中。

数据如下：

数据代表2个选中的复选框，带有隐藏的输入。

我正在使用以下ajax代码：

var formData = menuItem;

var formUrl = $('#nav-menu-meta').attr('action');

$.ajax({
    type: 'POST',
    url: formUrl,
    data: formData,
    success: function(response,textStatus,xhr) {
        console.log('test ', response);

    },
    error: function(xhr,textStatus,error) {
        console.error(textStatus, error);
    }
});

public function addmenuitems() {
    if ($this->request->is('ajax')) {
        $this->autoRender = false;
        $this->response->disableCache();
    }

    if ($this->request->is('post')) {

        $menuitemTable = TableRegistry::getTableLocator()->get('menuitems');
        $menuitems = $menuitemTable->newEntities($this->request->getData());

        foreach ($menuitems as $menuitem) {
            if ($menuitemTable->save($menuitem)) {
                $response = $this->response->withType('application/json')
                    ->withStringBody(json_encode($menuitem));
                return $response;
            }else{
                $message = 'Error';
            }
        }            
    }
}

数据根本没有保存，那我想念什么？

我从getData（）函数中添加了调试数据数组，以显示该数组包含的内容：

/src/Controller/Admin/Web/MenusController.php (line 109)

    (int) 0 => object(App\Model\Entity\MenuItem) {
