php - 如何在索引 View 中打印关联数据

Question

$subjects = $this->Subjects
    ->find('all', [
        'contain'=> [
            'Users'
        ],
        'fields'=> [
            'Users.username',
            'Users.email'
        ]
    ])
    ->hydrate(false)
    ->toArray();

$this->set('subjects', $subjects);

我如何循环显示 Subjects Controller 的 INDEX View 中的数据以显示此图像

Answer 1

来自您的 vardump 的示例结果:

<?php
$array = array(
    0 => array(
        'math'=>40,
        'english'=>40,
        'history'=>40,
        'science'=>40,
        'user_id'=>64
        'user'=>
            array(
            'id' => 6
            'name' => 'User',
            'email' => 'user1@sample.com'
            )
    )
);
?> 

这是根据您提供的vardump编写的示例代码:

<table>
    <thead>
    /// Give your table headers
    </thead>
<tbody>
    <?php foreach($subjects as $subject) :?>
        <tr>
            <td><?=$subject['math']?></td>
            <td><?=$subject['english']?></td>
            <td><?=$subject['history']?></td>
            <td><?=$subject['science']?></td>
            <td><?=$subject['user_id']?></td>
            <td><?=$subject['user']['id']?></td>
            <td><?=$subject['user']['name']?></td>
            <td><?=$subject['user']['email']?></td>
        </tr>
    <?php endforeach;?>
</tbody>
