データベースの準備

CREATE TABLE prefix_posts (
    id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
    title VARCHAR(50),
    body TEXT,
    created DATETIME DEFAULT NULL,
    modified DATETIME DEFAULT NULL
);
INSERT INTO prefix_posts (title,body,created)
    VALUES ('タイトル', 'これは、記事の本文です。', NOW());
INSERT INTO prefix_posts (title,body,created)
    VALUES ('またタイトル', 'そこに本文が続きます。', NOW());
INSERT INTO prefix_posts (title,body,created)
    VALUES ('タイトルの逆襲', 'こりゃ本当に面白そう！うそ。', NOW());

Modelの準備

[app/models/post.php]

<?php

class Post extends AppModel {
 var $name = 'Post';
 var $validate = array(
  'title' => array(
   'rule' => array('minLength', 1)
  ),
  'body' => array(
   'rule' => array('minLength', 1)
  )
 );
}
?>

Viewの準備

[views/test_apps/index.ctp]

<h1>Blog posts</h1>
<p><?php echo $html->link("Add Post", "/tests_apps_posts/add"); ?></p>
<table>
 <tr>
  <th>Id</th>
  <th>Title</th>
  <th>Created</th>
 </tr>

<!-- $post配列をループして、投稿記事の情報を表示 -->

<?php foreach ($posts as $post): ?>
 <tr>
  <td><?php echo $post['Post']['id']; ?></td>
  <td>
   <?php echo $html->link($post['Post']['title'],'/tests_apps_posts/view/'.$post['Post']['id']);?>
   <?php echo $html->link(
    'Delete',
    "/tests_apps_posts/delete/{$post['Post']['id']}",
    null,
    'Are you sure?'
   )?>
   <?php echo $html->link('Edit', '/tests_apps_posts/edit/'.$post['Post']['id']);?>
  </td>
  <td><?php echo $post['Post']['created']; ?></td>
 </tr>
<?php endforeach; ?>

</table>

[views/test_apps/edit.ctp]

<h1>Edit Post</h1>
<?php
 echo $form->create('Post', array('action' => 'edit'));
 echo $form->input('title');
 echo $form->input('body', array('rows' => '3'));
        echo $form->input('id', array('type'=>'hidden'));
 echo $form->end('Save Post');
?>

[views/test_apps/add.ctp]

<h1>Add Post</h1>
<?php
echo $form->create('Post');
echo $form->input('title');
echo $form->input('body', array('rows' => '3'));
echo $form->end('Save Post');
?>

[views/test_apps/view.ctp]

<h1><?php echo $post['Post']['title']?></h1>

<p><small>Created: <?php echo $post['Post']['created']?></small></p>

<p><?php echo $post['Post']['body']?></p>

Controllerの準備

[controllers/tests_apps_posts.php]

<?php

class TestsAppsPostsController extends AppController {
 var $name = 'TestsAppsPosts';
 var $uses = array('Post');
 var $viewPath = 'tests_apps';

 function index() {
  $this->set('posts', $this->Post->find('all'));
 }

 function view($id = null) {
  $this->Post->id = $id;
  $this->set('post', $this->Post->read());
 }

 function add() {
  if (!empty($this->data)) {
   if ($this->Post->save($this->data)) {
    $this->flash('Your post has been saved.','/posts');
   }
  }
 }

 function delete($id) {
  $this->Post->del($id);
  $this->flash('The post with id: '.$id.' has been deleted.', '/posts');
 }

 function edit($id = null) {
  $this->Post->id = $id;
  if (empty($this->data)) {
   $this->data = $this->Post->read();
  } else {
   if ($this->Post->save($this->data['Post'])) {
    $this->flash('Your post has been updated.','/posts');
   }
  }
 }
