下载后导入工程中，目录结构如下图（使用版本：1.1.19.6305）
搭建PHP环境，这里使用了AppServ2.5.9。 下载主页 http://www.php.cn/
MySQL中新建数据库blog,并运行如下SQL文建表。
立即学习“PHP免费学习笔记（深入）”；
/* First, create our posts table: */
CREATE TABLE posts (
id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
title VARCHAR(50),
body TEXT,
created DATETIME DEFAULT NULL,
modified DATETIME DEFAULT NULL
);
/* Then insert some posts for testing: */
INSERT INTO posts (title,body,created)
VALUES ('The title', 'This is the post body.', NOW());
INSERT INTO posts (title,body,created)
VALUES ('A title once again', 'And the post body follows.', NOW());
INSERT INTO posts (title,body,created)
VALUES ('Title strikes back', 'This is really exciting! Not.', NOW());
修改工程app/config/目录下database.php.default文件名为database.php，并修改其配置。
修改Apache的httpd.conf文件。
Apache2.2版本的，直接把#LoadModule rewrite_modulemodules/mod_rewrite.so的注释删掉即可。
2.0以前的版本，据说要修改2个地方： LoadModule rewrite_module libexec/httpd/mod_rewrite.so 和AddModule mod_rewrite.c
增加Model：
/app/models/post.php
代码：
require_once ('cake/app_model.php');
class Post extends AppModel {
public $name = 'Post';
public $validate = array(
'title' => VALID_NOT_EMPTY,
'body' => VALID_NOT_EMPTY
);
}
?>
增加Cotroller模块：
app/controllers/posts_controller.php
代码：
require_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');
$this->redirect("/posts/index");
}
}
}
}
?>
增加页面模块：
/app/views/下追加posts文件夹,然后再添加4个页面（一般后缀为.rhtml）
代码依次为：
index.thtml
Blog posts
link("Add Post", "/posts/add"); ?>
| Id | Title | Created |
|---|---|---|
|
link($post['Post']['title'], '/posts/view/'.$post['Post']['id']);?> link( 'Delete', "/posts/delete/{$post['Post']['id']}", null, 'Are you sure?' )?> link('Edit', '/posts/edit/'.$post['Post']['id']);?> |
view.thtml
Created:
link('Return', '/posts/index/');?>
edit.thtml
Edit Post
add.thtml
Add Post

以下是CakePHP框架的一些特性： http://www.lostk.com/blog/cakephp_note/
e="COLOR: #000000">
Title:
input('Post/title', array('size' => '40'))?>
tagErrorMsg('Post/title', 'Title is required.') ?>
Body:
textarea('Post/body', array('rows'=>'10')) ?>
tagErrorMsg('Post/body', 'Body is required.') ?>
submit('Save') ?>
