我在CakePHP 3中有一个新的用户表单，它收集用户的基本数据，例如用户名，电子邮件，姓名，电话等。这应该保存到Users表中，数据到表单中收集的数据，例如帐户是管理员，帐户创建的时间戳等等。所有这些其他字段都具有数据库中指定的默认值，例如0 {{1}在admin字段上，或false表示时间戳。我没有从表单中保存的其他人可以为空，没有默认值。
我遇到的问题是提交表单时，它会返回一般错误CURRENT_TIMESTAMP。我已使用The user could not be saved. Please, try again收集print_r数据以及request数据debug()，$user看起来不错，而request } $user表示我希望数据库插入默认值的数据。
我做错了什么，为什么表单不会提交我给出的值，而数据库设置其余的默认值？
我的控制器：
This field is required public function signup() {
// set page-specific values
$this->set('cakePage', false);
if (!$this->request->session()->check('Session.timestamp')) {
$this->redirect('/signup/home');
}
$user = $this->Users->newEntity();
if ($this->request->is('post')) {
$dob = implode("-", $this->request->data['birth_date']);
$this->request->data['birth_date'] = date('Y-m-d', strtotime($dob));
$user = $this->Users->patchEntity($user, $this->request->data);
if ($this->Users->save($user)) {
$this->Flash->success(__('The user has been saved.'));
return $this->redirect(['action' => 'index']);
} else {
$this->Flash->error(__('The user could not be saved. Please, try again.'));
// debug
print_r($this->request->data);
echo "<br>";
print_r($user);
}
}
$carriers = $this->Users->Carriers->find();
$this->set(compact('user', 'carriers'));
$this->set('_serialize', ['user']);
}
print_r($this->request->data); Array ( [username] => asdf [password] => asdf [email] => asdf@gmail.com
[first_name] => asdf [last_name] => asdf [birth_date] => 2000-01-01
[profile_image] => testUrl [bio] => Yo [phone] => 1234567890 [carrier] => 1 )
debug($user);
