Cake:让PHP也跑在铁轨上

类别:编程语言 点击:0 评论:0 推荐:

Cake是一个根据Ruby on Rails而架构的php 框架。和RoR一样,Cake也封装了对数据库的操作。目前Cake还不算一个成熟的框架,但是已经很值得关注了。

下边介绍下怎么在WAMP上安装Cake。

首先下载Cake Latest version: cake_0.2.9.zip


解压后,进入cakeconfig 将database.php.default改名为database.php,并对数据库的参数进行设置。如:

$DATABASE_CONFIG = array(
'devel' => array(
'host' => 'localhost',
'login' => 'user',
'password' => 'user',
'database' => 'cake'
)
);

然后Cake需要用到Apache的mod_rewrite,打开Apache的/config/httpd.conf,将

#LoadModule rewrite_module modules/mod_rewrite.so

前的#号去掉,

#AddModule mod_rewrite.c

前的#号去掉。

然后添加一个虚拟主机,比如

<VirtualHost *>
ServerAdmin [email protected]
DocumentRoot "F:/cake/"
ServerName cake.com
ErrorLog logs/cake.com.error_log
CustomLog logs/cake.my.com common
</VirtualHost>

<Directory "F:/cake/">
AllowOverride all
Order allow,deny
Allow from all
</Directory>

在 C:WINDOWSsystem32driversetchosts中加入一行本地host

127.0.0.1 cake.com

然后重启Apache和浏览器。

这时候Cake已经可以正常工作了。我们来创建一个应用:

在数据库中创建一个表

CREATE TABLE posts ( id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY, title VARCHAR(50), body TEXT, created DATETIME DEFAULT NULL, modified DATETIME DEFAULT NULL ); 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());

Cake是基于MVC模式的。创建一个应用时,我们先创建它的Model。

app/models/post.php <?PHP class Post extends AppModel { } ?>

然后创建Control

app/controllers/posts_controller.php <?PHP class PostsController extends AppController { } ?>

在其中加入index方法:

app/controllers/posts_controller.php (fragment) function index () { }

最后创建view

app/views/posts/index.thtml <table> <tr> <th>ID</th> <th>Title</th> <th>Created</th> </tr> <?PHP foreach ($this->post->find_all() as $post): ?> <tr> <td><?=$post['id']?></td> <td><?=$this->link_for($post['title'], "/posts/view/{$post['id']}"?></td> <td><?=$post['created']?></td> </tr> <?PHP endforeach ?> </table>

这样一个应用就完成了。

输入http://cake.com/posts/index 即可访问到我们刚才创建的程序。
