Question

我在cakephp 3中非常新。我想用多个复选框保存多个记录。我在活动表＆amp;中发现了一些事件。密码表中的一些密码。我想在每个事件下设置不同的密码。例如 - 对于事件1，我想设置一些密码，这些密码将存储在event_password_all表中。

（id，event1，password1），（id，event1，password2），（id，event1，password3）， ... ... （id，event1，passwordN）

我该怎么做。

这是我的控制器代码 -

    public function add()
{
    $eventPasswordAll = $this->EventPasswordAll->newEntity();
    if ($this->request->is('post')) {       
        $eventPasswordAll = $this->EventPasswordAll->patchEntity($eventPasswordAll, $this->request->data);
        if ($this->EventPasswordAll->save($eventPasswordAll)) {
            $this->Flash->success(__('The event password all has been saved.'));
            return $this->redirect(['action' => 'index']);
        } else {
            $this->Flash->error(__('The event password all could not be saved. Please, try again.'));
        }
    }
    $events = $this->EventPasswordAll->Events->find('list', ['limit' => 200]);
    $passwords = $this->EventPasswordAll->Passwords->find('list', ['limit' => 200]);
    $this->set(compact('eventPasswordAll', 'events', 'passwords'));
    $this->set('_serialize', ['eventPasswordAll']);
}

＆安培;这是视图 -

<div class="eventPasswordAll form large-10 medium-9 columns">
<?= $this->Form->create($eventPasswordAll) ?>
<fieldset>
    <legend><?= __('Add Event Password All') ?></legend>
    <?php
        echo $this->Form->input('event_id', ['options' => $events]);
        echo $this->Form->input('password_id', ['options' => $passwords, 'multiple' => 'checkbox']);
    ?>
</fieldset>
<?= $this->Form->button(__('Submit')) ?>
<?= $this->Form->end() ?>

Answer 1

3.2.8之前：
在CakePHP 3中没有像saveAll这样的事件。你必须遍历你的选择。

示例：

$passwords = $this->request->data('password_id');

foreach ($passwords as $password) {
    $data = [
        'event_id'    => $this->request->data('event_id'),
        'password_id' => $password
    ];
    $eventPasswordAll = $this->EventPasswordAll->newEntity();
    $this->EventPasswordAll->patchEntity($eventPasswordAll, $data);
    $this->EventPasswordAll->save($eventPasswordAll );
}

我没有测试它，但你明白了

＆gt; = 3.2.8

$data = [
    [
        'title' => 'First post',
        'published' => 1
    ],
    [
        'title' => 'Second post',
        'published' => 1
    ],
];
$articles = TableRegistry::get('Articles');
$entities = $articles->newEntities($data);
$result = $articles->saveMany($entities);

Answer 2

从CakePHP版本3.2.8开始，您可以一次保存多个记录。您可以使用cakephp文档中提到的以下代码。

https://book.cakephp.org/3.0/en/orm/saving-data.html#saving-multiple-entities

$data = [
 [
    'title' => 'First post',
    'published' => 1
 ],
 [
    'title' => 'Second post',
    'published' => 1
 ],
];
$articles = TableRegistry::get('Articles');
$entities = $articles->newEntities($data);
$result = $articles->saveMany($entities);
