CakePHP框架实例介绍分析。图文并茂
增加Cotroller模块：
app/controllers/posts_controller.php
代码：
<?phprequire_once ('cake/app_controller.php');class PostsController extends AppController { public $name = 'Posts'; function index() { $this->set('posts', $this->Post->findAll()); } function view($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'); $this->redirect("/posts/index"); } } } function delete($id) { $this->Post->del($id); //$this->flash('The post with id: '.$id.' has been deleted.', '/posts'); $this->redirect("/posts/index"); } function edit($id = null) { if (empty($this->data)) { $this->Post->id = $id; $this->data = $this->Post->read(); } else { if ($this->Post->save($this->data['Post'])) { //$this->flash('Your post has been updated.','/posts'); $this->redirect("/posts/index"); } } }}?>增加页面模块：
/app/views/下追加posts文件夹,然后再添加4个页面（一般后缀为.rhtml）
代码依次为：
index.thtml
<h1>Blog posts</h1><p><?php echo $html->link("Add Post", "/posts/add"); ?><table> <tr> <th>Id</th> <th>Title</th> <th>Created</th> </tr> <!-- Here's where we loop through our $posts array, printing out post info --> <?php foreach ($posts as $post): ?> <tr> <td><?php echo $post['Post']['id']; ?></td> <td> <?php echo $html->link($post['Post']['title'], '/posts/view/'.$post['Post']['id']);?> <?php echo $html->link( 'Delete', "/posts/delete/{$post['Post']['id']}", null, 'Are you sure?' )?> <?php echo $html->link('Edit', '/posts/edit/'.$post['Post']['id']);?> </td> </td> <td><?php echo $post['Post']['created']; ?></td> </tr> <?php endforeach; ?></table>view.thtml
<h1><?php echo $post['Post']['title']?></h1><p><small>Created: <?php echo $post['Post']['created']?></small></p><p><?php echo $post['Post']['body']?></p><br><p><?php echo $html->link('Return', '/posts/index/');?></p>edit.thtml
<h1>Edit Post</h1><form method="post" action="<?php echo $html->url('/posts/edit')?>"> <?php echo $html->hidden('Post/id'); ?> <p> Title: <?php echo $html->input('Post/title', array('size' => '40'))?> <?php echo $html->tagErrorMsg('Post/title', 'Title is required.') ?> </p> <p> Body: <?php echo $html->textarea('Post/body', array('rows'=>'10')) ?> <?php echo $html->tagErrorMsg('Post/body', 'Body is required.') ?> </p> <p> <?php echo $html->submit('Save') ?> </p></form>add.thtml
<h1>Add Post</h1><form method="post" action="<?php echo $html->url('/posts/add')?>"> <p> Title: <?php echo $html->input('Post/title', array('size' => '40'))?> <?php echo $html->tagErrorMsg('Post/title', 'Title is required.') ?> </p> <p> Body: <?php echo $html->textarea('Post/body', array('rows'=>'10')) ?> <?php echo $html->tagErrorMsg('Post/body', 'Body is required.') ?> </p> <p> <?php echo $html->submit('Save') ?> </p></form>测试URL: http://localhost/phpblog/posts/

以下是CakePHP框架的一些特性： http://www.lostk.com/blog/cakephp_note/
Title: <?php echo $html->input('Post/title', array('size' => '40'))?> <?php echo $html->tagErrorMsg('Post/title', 'Title is required.') ?> </p> <p> Body: <?php echo $html->textarea('Post/body', array('rows'=>'10')) ?> <?php echo $html->tagErrorMsg('Post/body', 'Body is required.') ?> </p> <p> <?php echo $html->submit('Save') ?> </p></form>
