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：

<?phpclass 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：

<?phpclass Post extends AppModel {public $validate = array( 'title' => array( 'rule' => 'notEmpty'), 'body' => array( 'rule' => 'notEmpty'));}?>

routes.php文件：
