Cakephp如何在索引视图中添加新记录

我是cakePHP新手，想知道如何在索引视图中添加一个表单来向数据库添加新记录。我的意思是，在Index.ctp中，可以显示记录列表，下面是一些占位符，带有添加按钮以插入dtb。我必须修改控制器吗

我试图在索引视图中添加一个表单，目标是../add，但在单击submit之后，它总是重定向到../add/{number}，我必须重新提交信息。以下是我试图修改的代码：

<div class="departments index large-9 medium-8 columns content">
<h3><?= __('Departments') ?></h3>
<table cellpadding="0" cellspacing="0">
    <thead>
        <tr>
            <th scope="col"><?= $this->Paginator->sort('id') ?></th>
            <th scope="col"><?= $this->Paginator->sort('name') ?></th>
            <th scope="col"><?= $this->Paginator->sort('modified') ?></th>
            <th scope="col" class="actions"><?= __('Actions') ?></th>
        </tr>
    </thead>
    <tbody>
        <?php foreach ($departments as $department): ?>
        <tr>
            <td><?= $this->Number->format($department->id) ?></td>
            <td><?= h($department->name) ?></td>
            <td><?= h($department->modified) ?></td>
            <td class="actions">
                <?= $this->Html->link(__('View'), ['action' => 'view', $department->id]) ?>
                <?= $this->Html->link(__('Edit'), ['action' => 'edit', $department->id]) ?>
                <?= $this->Form->postLink(__('Delete'), ['action' => 'delete', $department->id], ['confirm' => __('Are you sure you want to delete # {0}?', $department->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>
<div class="departments form large-9 medium-8 columns content">
<!-- $this->Form->create("Post",array('action'=>'add')); -->
    <?= $this->Form->create($department,['url' => ['action' => 'add']] ) ?>
    <fieldset>
        <legend><?= __('Add Department') ?></legend>
        <?php
            echo $this->Form->control('name');
            echo $this->Form->control('description');
            echo $this->Form->control('subjects._ids', ['options' => $subjects]);
        ?>
    </fieldset>
    <?= $this->Form->button(__('Submit')) ?>
    <?= $this->Form->end() ?>
</div>

看起来不错，您需要在索引方法中设置

$department

，并且您的表单在索引页面中，并且表单正在使用

$department

变量。请将您的索引方法设置为如下所示：

public function index()
{
  $departments = $this->paginate($this->Departments);
  $department = $this->Departments->newEntity(); // added
  // $this->add();
  $subjects = $this->Departments->Subjects->find('list', ['limit' => 200]);
  $this->set(compact('departments', 'subjects,'department')); // edited
  $this->set('_serialize', ['departments']);


}

嗯，我自己找到了答案，它是有效的，但我不知道这是否是解决这种情况的正确方法

我保持所有控制器与上面相同，只需更改index.ctp中的表单

<?= $this->Form->create(null,['url' => ['action' => 'add']] ) ?>
    <fieldset>
        <legend><?= __('Add Department') ?></legend>
        <?php
            echo $this->Form->control('name');
            echo $this->Form->control('description');
            echo $this->Form->control('subjects._ids', ['options' => $subjects]);
        ?>
    </fieldset>
    <?= $this->Form->button(__('Submit')) ?>
    <?= $this->Form->end() ?>

浏览博客教程@ManoharKhadka博客教程演示如何在不同视图（add.ctp、edit.ctp、view.ctp、index.ctp）中创建博客的视图编辑和视图列表。但是我想在同一个视图上同时执行函数Add（）和Index（）。CTP你能帮我回答下面的问题吗，我不确定它是否正确，但它确实有效。当然它是正确的。无论你在Add方法中做什么，你也可以在Index方法中做。一点问题都没有。。

<?= $this->Form->create(null,['url' => ['action' => 'add']] ) ?>
    <fieldset>
        <legend><?= __('Add Department') ?></legend>
        <?php
            echo $this->Form->control('name');
            echo $this->Form->control('description');
            echo $this->Form->control('subjects._ids', ['options' => $subjects]);
        ?>
    </fieldset>
    <?= $this->Form->button(__('Submit')) ?>
    <?= $this->Form->end() ?>
