基于CakePHP实现的简单博客系统实例_php实例

这篇文章主要介绍了基于CakePHP实现的简单博客系统,以一个完整实例分析了使用CakePHP实现博客系统的完整流程,需要的朋友可以参考下

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(&#39;Html&#39;, &#39;Form&#39;, &#39;Session&#39;);
 public $components = array(&#39;Session&#39;);
 public function index() 
 {
   $this->set(&#39;posts&#39;, $this->Post->find(&#39;all&#39;));
 }
 public function view($id=null)
 {
   $this->Post->id=$id;
   $this->set(&#39;post&#39;,$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(&#39;action&#39;=>&#39;index&#39;));
    }
    else
    {
      $this->Session->setFlash("unable to create post!");
    }
   }
 }
 public function edit($id=null)
 {
   $this->Post->id=$id;
   if($this->request->is(&#39;get&#39;))
   {
     $this->request->data = $this->Post->read();
   }
   else
   {
     if($this->Post->save($this->request->data)) 
     {
       $this->Session->setFlash(&#39;Your post has been updated.&#39;);
       $this->redirect(array(&#39;action&#39; => &#39;index&#39;));
     }
     else
     {
       $this->Session->setFlash(&#39;Unable to update your post.&#39;);
     }
   }
 }
 public function delete($id) {
    if ($this->request->is(&#39;get&#39;)) {
        throw new MethodNotAllowedException();
    }
    if ($this->Post->delete($id)) {
      $this->Session->setFlash(&#39;The post with id: &#39; . $id . &#39; has been deleted.&#39;);
      $this->redirect(array(&#39;action&#39; => &#39;index&#39;));
    }
 }
}
?>

Post.php文件：

<?php
class Post extends AppModel {
public $validate = array(
 &#39;title&#39; => array(
 &#39;rule&#39; => &#39;notEmpty&#39;
),
 &#39;body&#39; => array(
 &#39;rule&#39; => &#39;notEmpty&#39;
)
);
}
?>

routes.php文件：

<?php

 * Routes are very important mechanism that allows you to freely connect
 * different urls to chosen controllers and their actions (functions).

  //Router::connect(&#39;/&#39;, array(&#39;controller&#39; => &#39;pages&#39;, &#39;action&#39; => &#39;display&#39;, &#39;home&#39;));
