Question

我正在使用CakePHP 3.6.7，我的问题是当我以控件形式使用关联数据时，出现无法发出标题警告的情况。

这是我的代码：

AppController.php初始化函数（如果用户已登录，我将从此处检索其所有数据）

public function initialize() {

parent::initialize();

// Retrieve user data for all views
if($this->request->getSession()->read('Auth.User')) {
    $this->user = $this->Users->get($this->request->getSession()->read('Auth.User.id'), [
        'contain' => ['UserPersonalData']
    ]); 
    $this->set('user', $this->user);
    $this->set('_serialize', 'user');
}

}

UserPersonalDataController.php初始化函数

public function initialize()
{
    parent::initialize();

}

UserPersonalDataController.php编辑功能

public function edit()
{
    if ($this->request->is(['patch', 'post', 'put'])) {
        $userPersonalData = $this->Users->patchEntity($this->user, $this->request->getData());
        if ($this->Users->save($userPersonalData)) {
            $this->Flash->success(__('The user personal data has been saved.'));

            return $this->redirect($this->user->username);
        }
        $this->Flash->error(__('The user personal data could not be saved. Please, try again.'));
    }
}

edit.ctp，以下格式将在调试模式下引发无法发出标头的警告

<div class="container" style="padding: 2rem">
<div class="users form large-9 medium-8 columns content">
    <?= $this->Form->create($user, [
        'class' => 'form-signin',
    ]); ?>
    <fieldset>
        <legend><?= __('Edit User') ?></legend>
        <?php
            echo $this->Form->control('user_personal_data.firstName', ['required' => true, 'class' => 'form-control', 'placeholder' => 'First Name', 'label' => false]);
            echo $this->Form->control('user_personal_data.lastName', ['required' => true, 'class' => 'form-control', 'placeholder' => 'Last Name', 'label' => false]);
            echo $this->Form->control('user_personal_data.phone', ['required' => true, 'class' => 'form-control', 'placeholder' => 'Phone', 'label' => false]);
        ?>
    </fieldset>
    <?= $this->Form->button(__('Submit'), ['class' => 'btn btn-lg btn-primary btn-block' ]) ?>
    <?= $this->Form->end() ?>
</div>

edit.ctp，以下格式不会引发任何警告

<div class="container" style="padding: 2rem">
<div class="users form large-9 medium-8 columns content">
    <?= $this->Form->create($user, [
        'class' => 'form-signin',
    ]); ?>
    <fieldset>
        <legend><?= __('Edit User') ?></legend>
        <?php
            echo $this->Form->control('email', ['required' => true, 'class' => 'form-control', 'placeholder' => 'First Name', 'label' => false]);
        ?>
    </fieldset>
    <?= $this->Form->button(__('Submit'), ['class' => 'btn btn-lg btn-primary btn-block' ]) ?>
    <?= $this->Form->end() ?>
</div>

正如我所说，如果我在control（）窗体帮助器中使用关联的数据，它将在调试模式下抛出该警告。如果我不处于调试模式，它将可以正常工作，但我对此感到担心。感谢您的帮助！

问题是，正如Greg Schmidt所说，我有一个格式不正确的数值。解决了！
