CakePHP：將多個條目從另一個控制器保存到模型

Question

我有一個具有“學校”表和“學生”表的數據庫。 顯然，一所學校有很多學生，這在DB中有代表。

在CakePHP中進行“烘焙”之后，我的添加函數都可以使用其默認格式。 我可以創造學生，也可以創造學校。 但是，我希望每當創建學校時都能創建兩個學生。 因此，我在學校的“ add.ctp”文件中設置了這樣的表單：

<?= $this->Form->create('school') ?>
<fieldset>
    <legend><?= __('Add School') ?></legend>
    <?php

    // create the school
    echo $this->Form->input('school_name');
    echo $this->Form->input('school_description');

    echo $this->Form->input('student.0.name');
    echo $this->Form->input('student.0.description');
    echo $this->Form->input('student.1.name');
    echo $this->Form->input('student.1.description');

    ?>
</fieldset>
<?= $this->Form->button(__('Submit')) ?>
<?= $this->Form->end() ?>

但是我找不到解決方案可以修改SchoolsController.php文件中學校的“添加”功能來保存兩個學生。 我該怎么做？

編輯：這是POST數據：

Array
(
    [school_name] => Harvard
    [school_description] => A University
    [students] => Array
        (
            [0] => Array
                (
                    [name] => Bob Brown
                    [description] => Likes frogs
                )

            [1] => Array
                (
                    [name] => James Jones
                    [description] => Plays trumpet
                )

            [2] => Array
                (
                    [name] => Sarah Simmer
                    [description] => Enjoys movies
                )
        )
)

Answer 1

您提供的發布數據似乎正確，因此您可以像這樣修改保存功能：

$school = $this->Schools->newEntity($this->request->data, ["associated" => ["Students"]]);
$this->Schools->save($school);

Answer 2

在您的添加函數中：

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

    $students = $this->Students->newEntities($this->request->data()['students']);

    foreach ($students as $student) {
        $this->Students->save($student);
    }
}
