Cake Architecture Primer

(i) Introduction

This article mainly describes the cake architecture, and how to install the configuration using this architecture to get started to develop.

(b) requirements (1) to understand the basic PHP code. (2) A apache+mysql+php development environment has been configured.

(iii) Body (1) Cake Introduction

Cake is an MVC framework based on PHP, free and open source. It is simpler than some other PHP architectures, such as the Zend Framework, to enable faster and more flexible creation of network applications. So it's easy for beginners to get started.

Cake has the following characteristics:

Have a friendly and active community

A flexible MIT License

Compatible PHP4 and PHP5

Database interaction using CRUD

Application Scaffolding

Code generation automatically (code generator)

MVC Architecture

Clear, clean, highly customizable URLs and routing request distributors

Built-in validation verification

Quick and flexible template mechanism (PHP syntax, with helpers)

Ajax, JavaScript, HTML forms and more View assistant tools

Messages, cookies, security, sessions (session), and components that request processing

A flexible ACL access control mechanism

Data cleanup

Flexible View Caching caching

Localization

can work in any subdirectory, with little or no need to change any Apache-related configuration

(2) Configuration development

Download cake from http://cakephp.org/, the current latest version is: 1.2.3.8166

After downloading to the root directory of the server, such as:/wwwroot/first_app, and can change the root directory directly pointing to First_appappwebroot, such as: DocumentRoot "D:phpwwwrootfirst_ Appappwebroot "

Restart the Apache service. Browse: http://localhost/

If you see the same page as this one, your Apache service is configured correctly. You can also see 4 tips on the page, and yellow is what you have to configure.

The configuration is as follows:

1. Find Configure::write in first_appappconfigcore.php (' Security.salt ', ' dyhg93b0qyjfixfs2guvouubwwvnir2g0fgac9mi ');

Just change the Back button to any string of 40 or so.

2. Change file First_Appappconfigdatabase.php.default file name to: database.php, changing the database connection inside, you can delete the configuration of test, the final configuration is as follows:

Class Database_config {

var $default = Array (

' Driver ' => ' MySQL ',

' Persistent ' => false,

' Host ' => ' localhost ',

' Login ' => ' root ',

' Password ' => ' 123 ',

' Database ' => ' cake ',

' Prefix ' => ',

);

}

3. If first_appapptmp is not writable, it needs to be changed to writable.

After you change it, you can browse http://localhost/again, and you'll notice that the yellow tip turns green all over.

4. Routing configuration, this is the key to the entire configuration to ensure that the key to the correct.

The action that the route uses to map URLs and controllers

Default route for URL styles:

Http://example.com/controller/action/param1/param2/param3

Modify httpd.conf Open Mod_rewrite

1 Get rid of #loadmodule Rewrite_module modules/mod_rewrite.so before #

2 at the same time change allowoverride none to allowoverride all

Such as:

　　

Options FollowSymLinks

AllowOverride All

　　

The above is to set all the site directory to allowoverride all, if the All,apache service will. htaccess to control the route, set to none, will not be processed under the directory. Routing in htaccess

You can specify a separate directory for routing, and you need to add the directory you want to specify. such as:

　　

AllowOverride All

　　

You need to restart the Apache service after changing the httpd.conf.

(3) using the architecture

If the configuration is correct, you can add your own code.

3.1 Creating a database table

Create Table Items

(

ID int (one) unsigned auto_increment,

Name varchar (200),

Text varchar (200),

Createtime timestamp default Current_timestamp,

Primary KEY (ID)

)

Insert into Items (name,text) VALUES (' Item 1 ', ' Item 1 content ');

3.2 Creating Model:First_AppappmodelsItem.php

　　

Create Item extends appmodel{

var $name = ' Item ';

}

?>

3.3 Creating Controller:First_AppappcontrollersItems_Controller.php

　　

Class Itemscontroller extends appcontroller{

var $name = ' Items ';

var $scaffold;

}

?>

3.4 Browse: Http://localhost/Items, after the results are as follows:
