基于CakePHP实现的简单博客系统实例
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
/**
* Routes configuration
*
* 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';
