4. parse and paginate

とりあえずpaginate。

D:/test/cakephp/app/controllers/pages_controller.php を作成

<?php

class PagesController extends AppController {

    public $uses = array('Guest');
    public $helpers = array('Paginator');
    public $paginate = array(
        'Guest' => array(
            'order' => 'created DESC',
            'limit' => 5,
        ),
    );

    public function guestbook()
    {
        if (!empty($this->data['Guest'])) {
            if ($this->Guest->save($this->data)) {
                $this->redirect('/pages/guestbook');
                return;
            }
        }
        
        $guests = $this->paginate('Guest');
        
        $this->set(compact('guests'));
    }
}

D:/test/cakephp/app/views/elements/paginate.ctp を作成

<?php echo $paginator->counter(array('format'=>'<%count% 件中 %start% から %end% までを表示>')); ?>
<br/>
ページ：<?php echo $paginator->numbers(); ?>

D:/test/cakephp/app/views/pages/guestbook.ctp を作成

<?php echo $form->create('Page', array('url'=>'/pages/guestbook')); ?>
<table>
  <tr>
    <td>お名前：
      <?php echo $form->error('Guest.name', 'お名前を入力してください。'); ?>

                                'email' => 'メールアドレスを正しく入力してください。',
                             )); ?>
      <?php echo $form->text('Guest.mail'); ?>
    </td>
  </tr>
  <tr>

                             )); ?>
      <?php echo $form->text('Guest.url'); ?>
    </td>
  </tr>
  <tr>
    <td><?php echo $form->submit('登録'); ?></td>
  </tr>
</table>
<?php echo $form->end(); ?>

<?php echo $this->renderElement('paginate'); ?>

<?php foreach($guests as $guest): ?>
<table>
  <tr>
    <td>
      <?php echo h($guest['Guest']['content']); ?>
      <br/>

	  <?php echo h(date('Y/m/d H:n', strtotime($guest['Guest']['created']))); ?>
    </td>
  </tr>
</table>
<?php endforeach; ?>

<?php echo $this->renderElement('paginate'); ?>

RSSの取得

D:/test/cakephp/app/controllers/pages_controller.php を作成

<?php

class PagesController extends AppController {
    public $uses = null;

    public function rss()
    {
        App::import('Core', 'Xml');
        $xml = new XML("http://d.hatena.ne.jp/bobchin/rss");
        
        $xml = Set::reverse($xml);
        $items = $xml['RDF']['Item'];
        $this->set(compact('items'));
    }
}

D:/test/cakephp/app/views/pages/rss.ctp を作成

<?php if(!empty($items)): ?>
<table>
  <?php echo $html->tableHeaders(array_keys($items[0]));?>
<?php   foreach($items as $item): ?>
  <?php echo $html->tableCells($item); ?>
<?php   endforeach; ?>
</table>
<?php endif; ?>


配列のpaginateはどうすべか。
小細工で対応。

D:/test/cakephp/app/models/rss.php を作成

    public $name = 'Rss';
    public $useTable = false;

    private $paginateData = array();
    public function setPaginateData($array)
    {
        $this->paginateData = $array;
        return $this;
    }

    public function find($conditions = null, $fields = array(), $order = null, $recursive = null)
    {
        if (low($conditions) == 'count') {
            return count($this->paginateData);
        } else {
            $page = ($fields['page'] < 1)? 1: $fields['page'];
            $limit = ($fields['limit'] < 1)? 1: $fields['limit'];
            
            $index = ($page-1)*$limit;
            return array_slice($this->paginateData, $index, $limit);
        }
    }

}

D:/test/cakephp/app/controllers/pages_controller.php を作成

        $this->Rss->setPaginateData($items);
        $items = $this->paginate('Rss');
        $this->set(compact('items'));
