Question

我是cakephp的初学者，现在我正在使用cakephp 3.5。我需要创建表单时遇到问题。我想要创建的表单来自索引视图，它有多个复选框。我的问题是每当我点击复选框时，数据都没有保存。

表单的名称是existing_question.ctp。这是代码。

<?php
/**
 * @var \App\View\AppView $this
 * @var \App\Model\Entity\Question[]|\Cake\Collection\CollectionInterface $questions
 */
?>
<nav class="large-3 medium-4 columns" id="actions-sidebar">
    <ul class="side-nav">
        <li class="heading"><?= __('Actions') ?></li>
        <li><?= $this->Html->link(__('New Question'), ['action' => 'add']) ?></li>
        <li><?= $this->Html->link(__('List Question Quizzes'), ['controller' => 'QuestionQuizzes', 'action' => 'index']) ?></li>
        <li><?= $this->Html->link(__('New Question Quiz'), ['controller' => 'QuestionQuizzes', 'action' => 'add']) ?></li>
    </ul>
</nav>
<div class="questions index large-9 medium-8 columns content">
    <h3><?= __('Questions') ?></h3>
    <?= $this->Form->create($questions) ?>
    <table cellpadding="0" cellspacing="0">
        <thead>
            <tr>
                <th scope="col"><?= $this->Paginator->sort('checked') ?></th>
                <th scope="col"><?= $this->Paginator->sort('id') ?></th>
                <th scope="col"><?= $this->Paginator->sort('question') ?></th>
                <th scope="col"><?= $this->Paginator->sort('marks') ?></th>
                <th scope="col" class="actions"><?= __('Actions') ?></th>
            </tr>
        </thead>
        <tbody>
            <?php foreach ($questions as $question): ?>
            <tr>

                <td><?= $this->Form->control('', ['type' => 'checkbox']) ?></td>
                <td><?= $this->Number->format($question->id) ?></td>
                <td><?= h($question->question) ?></td>
                <td><?= $this->Number->format($question->marks) ?></td>
                <td class="actions">
                    <?= $this->Html->link(__('View'), ['action' => 'view', $question->id]) ?>
                    <?= $this->Html->link(__('Edit'), ['action' => 'edit', $question->id]) ?>
                    <?= $this->Form->postLink(__('Delete'), ['action' => 'delete', $question->id], ['confirm' => __('Are you sure you want to delete # {0}?', $question->id)]) ?>
                </td>
            </tr>
            <?php endforeach; ?>
        </tbody>
    </table>
    <div class="paginator">
        <ul class="pagination">
            <?= $this->Paginator->first('<< ' . __('first')) ?>
            <?= $this->Paginator->prev('< ' . __('previous')) ?>
            <?= $this->Paginator->numbers() ?>
            <?= $this->Paginator->next(__('next') . ' >') ?>
            <?= $this->Paginator->last(__('last') . ' >>') ?>
        </ul>
        <p><?= $this->Paginator->counter(['format' => __('Page {{page}} of {{pages}}, showing {{current}} record(s) out of {{count}} total')]) ?></p>
    </div>
    <?= $this->Form->button(__('Submit'), ['controller' => 'QuestionQuizzes', 'action' => 'index', $this->request->pass[1]]) ?>
    <?= $this->Form->end() ?>
</div>

这是我的控制者。

        $this->set(compact('questions'));
        $this->set('_serialize', ['questions']);
    }

    public function view($id = null)

        $question = $this->Questions->get($id);
        if ($this->Questions->delete($question)) {

        } else {

        $this->set(compact('questions'));
       $this->set('_serialize', ['questions']);

}

我认为问题在于现有的问题功能。我不知道在同一个函数中合并索引和添加动作的正确方法。我尝试了很多方法，但它仍然失败了。提前谢谢。

EDITED：我有表格问题，我想要创建的表单来从该表中获取数据。然后，我需要在id旁边添加多个复选框。我尝试了很多方法，但似乎不对。 I want the form to be like this

Answer 1

您希望获得所选问题的ID吗？要获取该数据，请尝试类似

的内容

$this->Form->control('questions[]', ['type' => 'checkbox', 'value' => $question->id])

您的$this->request->getData()应该有一个名为问题的数组，其中包含所选ID列表。

当您将数据发布到existingQuestion方法时，您的下一个挑战就是要做好准备，因为现在正在尝试创建一个新问题，当您真正想要的时候是向现有测验添加问题。（该方法可能应该命名为addQuestions而不是在测验控制器中？）要将问题添加到测验中，请阅读Associating Many To Many Records。

合并索引并在cakephp 3.5中将操作添加到表单中
