本文实例讲述了基于CakePHP实现的简单博客系统。分享给大家供大家参考。具体实现方法如下：

PostsController.php文件：

<?php

class PostsController extends AppController {

public $helpers = array('Html', 'Form', 'Session');

public $components = array('Session');

public function index()

{

$this->set('posts', $this->Post->find('all'));

}

public function view($id=null)

{

$this->Post->id=$id;

$this->set('post',$this->Post->read());

}

public function add()

{

if($this->request->is("post"))

{

$this->Post->create();

if($this->Post->save($this->request->data))

{

$this->Session->setFlash("your post added!");

$this->redirect(array('action'=>'index'));

}

else

{

$this->Session->setFlash("unable to create post!");

}

public function edit($id=null)

{

$this->Post->id=$id;

if($this->request->is('get'))

{

$this->request->data = $this->Post->read();

}

else

{

if($this->Post->save($this->request->data))

{

$this->Session->setFlash('Your post has been updated.');

$this->redirect(array('action' => 'index'));

}

else

{

$this->Session->setFlash('Unable to update your post.');

}

public function delete($id) {

if ($this->request->is('get')) {

throw new MethodNotAllowedException();

}

if ($this->Post->delete($id)) {

$this->Session->setFlash('The post with id: ' . $id . ' has been deleted.');

$this->redirect(array('action' => 'index'));

}

Post.php文件：

<?php

class Post extends AppModel {

public $validate = array(

'title' => array(

'rule' => 'notEmpty'

'body' => array(

'rule' => 'notEmpty'

)

);

}

routes.php文件：

<?php

/**

* In this file, you set up routes to your controllers and their actions.

* Routes are very important mechanism that allows you to freely connect

* different urls to chosen controllers and their actions (functions).

/**

* Here, we are connecting '/' (base path) to controller called 'Pages',

* its action called 'display', and we pass a param to select the view file

* to use (in this case, /app/View/Pages/home.ctp)...

//Router::connect('/', array('controller' => 'pages', 'action' => 'display', 'home'));

Router::connect('/', array('controller' => 'posts', 'action' => 'index'));

/**

* ...and connect the rest of 'Pages' controller's urls.

Router::connect('/pages/*', array('controller' => 'pages', 'action' => 'display'));

/**

* Load all plugin routes. See the CakePlugin documentation on

* how to customize the loading of plugin routes.

CakePlugin::routes();

/**

* Load the CakePHP default routes. Only remove this if you do not want to use

* the built-in default routes.

require CAKE . 'Config' . DS . 'routes.php';
