Question

我有一个包含'Schools'表和'Students'表的数据库。显然，一所学校有很多学生，这在数据库中有所体现。

在CakePHP中'烘焙'后，我的添加功能都可以使用默认表单。我可以创造学生，我可以创建学校。但是，每当我创建一所学校时，我希望能够创建两名学生。所以我在学校的'add.ctp'文件中设置了这样的表格：

<?= $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() ?>

然而，我找不到的解决方案是能够在SchoolsController.php文件中修改学校的“添加”功能，以便能够保存这两个学生。我该怎么做？

编辑：以下是POST数据：

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

您提供的帖子数据似乎是正确的，因此您可以像这样修改保存功能：

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

Answer 2

在你的添加功能中：

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

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

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