commentController

<?php

namespace App\Controller;

class CommentsController extends AppController
{
	public function  add()
	{
		$this->viewBuilder()->layout('my_layout');
		$comment = $this->Comments->newEntity();
		if($this->request->is('post')){
			$comment = $this->Comments->patchEntity($comment, $this->request->data);
			if($this->Comments->save($comment)){
				$this->Flash->success('Comment Add Success!');
				return $this->redirect(['controller'=>'Posts','action'=>'view', $comment->post_id]);
			}else {
				$this->Flash->success('Error');
			}
		}
		$this->set('post', $comment);
	}

	public function delete($id = null)
	{
		$this->viewBuilder()->layout('my_layout');
		$this->request->allowMethod(['post', 'delete']);
		$comment = $this->Comments->get($id);
		if($this->Comments->delete($comment)){
			$this->Flash->success('Comment Delete Success!');
			
		}else {
			$this->Flash->success('Error');
		}
		return $this->redirect(['controller'=>'Posts','action'=>'view', $comment->post_id]);

	}
}
?>

controllerでgetして、$this->Posts->save

public function edit($id = null)
	{
		$this->viewBuilder()->layout('my_layout');
		$post = $this->Posts->get($id);
		if($this->request->is(['post','patch','put'])){
			$post = $this->Posts->patchEntity($post, $this->request->data);
			if($this->Posts->save($post)){
				$this->Flash->success('Edit Success!');
				return $this->redirect(['action'=>'index']);
			}else {
				$this->Flash->success('Error');
			}
		}
		$this->set('post', $post);
	}

deleteは $this->Posts->deleteになる

public function edit($id = null)
	{
		$this->viewBuilder()->layout('my_layout');
		$this->request->allowMethod(['post', 'delete']);
		$post = $this->Posts->get($id);
		if($this->Posts->delete($post)){
			$this->Flash->success('Delete Success!');
			
		}else {
			$this->Flash->success('Error');
		}
		return $this->redirect(['action'=>'index']);

	}

<?= $this->Form->create($post); ?>
<?= $this->Form->input('title'); ?>
<?= $this->Form->input('body', ['rows'=> '3']); ?>
<?= $this->Form->button('Add'); ?>
<?= $this->Form->end(); ?>

なるほど、だんだんテンションが下がってきた。

DBへのinsertをcontrollerで書きます。

public function  add()
	{
		$this->viewBuilder()->layout('my_layout');
                $post = $this->Posts->newEntity();
		if($this->request->is('post')){
			$post = $this->Posts->patchEntity($post, $this->request->data);
			$this->Posts->save($post);
			return $this->redirect(['action'=>'index']);
		}
		$this->set('post', $post);
	}

validatorはmodelに書きます。

<?php

namespace App\Model\Table;

use Cake\ORM\Table;
use Cake\Validation\Validator;

class PostsTable extends Table
{
	public function initialize(array $config)
	{
		$this->addBehavior('Timestamp');
	}

	public function validationDefault(Validator $validator)
		{
			$validator
			->notEmpty('title')
			->requirePresence('title')
			->notEmpty('body')
			->requirePresence('body')
			->add('body', [
				'length' => [
					'rule' => ['minLength', 10],
					'message' => 'body length must be 10+'
					]
				]);
		return $validator;
	}
}

controllerでvalidationの設定

public function  add()
	{
		$this->viewBuilder()->layout('my_layout');
		$post = $this->Posts->newEntity();
		if($this->request->is('post')){
			$post = $this->Posts->patchEntity($post, $this->request->data);
			if($this->Posts->save($post)){
				return $this->redirect(['action'=>'index']);
			}else {
				// error
			}
		}
		$this->set('post', $post);
	}

index.ctp

Htmlヘルパーを使う場合
Html->linkとする　テーブルのカラムを指定し、コントローラーとアクションを作成。
うーん、慣れるまで時間がかかりそう。

<?php foreach($posts as $post):?>
		<li><?= $this->Html->link($post->title, ['controller'=>'Posts', 'action'=>'view']); ?></li>
	<?php endforeach; ?> 

ブラウザで確認。反映されてますね。

urlヘルパーを使う場合

<a href="<?= $this->Url->build(['action'=>'view', $post->id]); ?>">
		<?= h($post->title); ?></a>

Htmlヘルパーの方がコード量が少なく楽そうに見えます。

共通ヘッダーをつくります。
app/src/Template/Element/my_header.ctp

<header>My Blog</header>

作ったelementをレイアウトファイルに書き込みます。
app/src/Template/Layout/my_layout.ctp

<!DOCTYPE html>
<html>
<head>
    <?= $this->Html->charset() ?>
    <title>
        <?= $this->fetch('title') ?>
    </title>
    <?= $this->Html->css('styles.css') ?>
</head>

<body>
		<?= $this->element('my_header') ?>
        <section class="container">
        <?= $this->fetch('content') ?>
        </section>

</body>
</html>

サーバーを再起動します。
bin/cake server -H 192.168.33.10 -p 8000

ブラウザ読み込みます。なるほど、エレメントはパーツですね。

PostController.phpはAppControllerのclassをextendしているので、AppControllerのクラスに記載してもOK
$this->viewBuilder()->layout(‘my_layout’);
