如何在cakephp 3中保存多条记录

Question

我是 cakephp 3 的新手。我想用多个复选框保存多条记录。我在事件 table 中有一些事件，在密码 table 中有一些密码。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 table.

(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']);
}

&这里是视图-

<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：
CakePHP 3 中没有 saveAll 这样的事件。您必须遍历您的选项。

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 );
}

我没有测试过，但你明白了

>= 3.2.8
让人们走在正确的轨道上。
从 3.2.8 开始，有一种方法可以更有效地做到这一点。

$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，您可以一次保存多条记录。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);
