CakePHP2.3.0-the first day of beta

Because CakePHP does not have a good Chinese manual, take notes during study. At the beginning, I should not give it all the reason. I will do it again, so I can see the effect, and I will learn it later. My environment is AppServ.

Because CakePHP does not have a good Chinese manual, take notes during study. At the beginning, I should not give it all the reason. I will do it again, so I can see the effect, and I will learn it later. My environment is AppServ, installed in C:/AppServ/, the root directory is C:/AppServ/www/, and cakephp is placed in

C:/AppServ/www/cakephp/

Precautions in advance:

Load rewrite module

Make sure that apache modules are loaded:

LoadModule rewrite_module libexec/apache2/mod_rewrite.so

And strict directory rewriting is allowed.

 

Options FollowSymLinks

AllowOverride All

# Order deny, allow

# Deny from all

 

 

Enable the pdo_mysql module in php (remove the module in the php configuration file; or # remove it)

 

1. download cakephp2.3.0-beta.zip

Web: https://github.com/cakephp/cakephp/tags

 

2. decompress the package and change the name to cakephp. put it to the root directory of the website.

2.1 make sure that the app/tmp directory and sub-directories have the write permission. you can ignore this permission on windows servers.

 

3. configure the database connection information and security-related configuration values.

 

3.1 database configuration: copy app/config/database. php. default and name it database. php. it mainly configures the user name and password, database, and table prefix.

Public $ default = array (

'Datasource '=> 'Database/mysql ',

'Persistent' => false,

'Host' => 'localhost ',

'Login' => 'root', // mysql User name

'Password' => 'root', // mysql password

'Database' => 'test', // database name

'Prefix' => '', // table prefix

// 'Encoding' => 'utf8', // character set encoding default utf8

);

 

3.2 configure security parameters: find the following options in app/config/core. php and replace the values with random strings.

Configure: write ('security. salt', 'Random string after replacement ');

Configure: write ('security. herherseed', 'Random number after replacement ');

 

4. create a data table and insert test data

 

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 ());

 

5. create a model and add automatic verification rules

Create Post. php under app/Model/(pay attention to naming conventions, capital of the first letter of the file), write the previous class, and add automatic verification rules

 

Class Post extends AppModel {

// Verification rules. The title and body fields cannot be blank.

Public $ validate = array (

'Title' => array (

'Rule' => 'notempty'

),

'Body' => array (

'Rule' => 'notempty'

)

);

}

 

6. create a controller and write down the method

 

Create PostsController under app/Controller. php (note the naming rules. The first letter of the name is in upper case and the complex form of the table is used: for example, peopleController. php, BooksController. php) now, if you want to access the view method, you can use http: // localhost/cakephp/posts/view

 

 

Class PostsController extends AppController {

 

Public $ helpers = array ('html', 'form ');

 

Public function index () {// query all records in the Post table and send the results to the view layer.

$ This-> set ('posts', $ this-> Post-> find ('all '));

}

 

Public function view ($ id) {// query a record based on the id

$ This-> Post-> id = $ id;

$ This-> set ('post', $ this-> post-> read ());

}

 

Public function add () {// add method

If ($ this-> request-> is ('post ')){

$ This-> Post-> create ();

If ($ this-> Post-> save ($ this-> request-> data )){

$ This-> Session-> setFlash ('Your post has been saved .');

$ This-> redirect (array ('action' => 'index '));

} Else {

$ This-> Session-> setFlash ('unable to add your post .');

}

}

}

 

Public function edit ($ id = null) {// edit method

$ 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) {// delete method

If ($ this-> request-> is ('get ')){

Throw new MethodNotAllowedException ();

}

If ($ this-> Post-> delete ($ id )){

$ This-> Session-> setFlash ('post with id: '. $ id. 'has been deleted .');

$ This-> redirect (array ('action' => 'index '));

}

}

 

}

 

 

7. create a view layer

 

Create a directory Posts/in app/View/, and then create index. ctp under the Directory (the default template suffix is ctp. Modify the template suffix in app/AppController. add a member attribute public $ ext = '.html '; to the class AppController extends Controller {} class in the PHP file.) (to modify other configuration information, refer to the core file: lib/Cake/Controller. php. all attributes can be customized. you can modify the attributes in the core file or in app/AppController. php modification, which is created in the app for easy framework upgrade)

 

Blog posts

Html-> link ('add post', array ('action' => 'Add');?>

 

 

Id	Title	Actions	Created
	Html-> link ($ post ['post'] ['title'], array ('action' => 'view ', $ post ['post'] ['id']);?>	Form-> postLink ( 'Delete ', Array ('action' => 'Delete', $ post ['post'] ['id']), Array ('confirm' => 'Are you sure? ')); ?> Html-> link ('edit', array ('action' => 'edit', $ post ['post'] ['id']);?>

 

Continue to create view. ctp for browsing a single record

 

 

 

Created:

 

 

Continue to create the edit record Template edit. ctp

 

 

Edit Post

Echo $ this-> Form-> create ('post', array ('action' => 'Edit '));

Echo $ this-> Form-> input ('title ');

Echo $ this-> Form-> input ('body', array ('rows '=> '3 '));

Echo $ this-> Form-> input ('id', array ('type' => 'den den '));

Echo $ this-> Form-> end ('save Post ');

 

Add. ctp

 

 

Add Post

Echo $ this-> Form-> create ('post ');

Echo $ this-> Form-> input ('title ');

Echo $ this-> Form-> input ('body', array ('rows '=> '3 '));

Echo $ this-> Form-> end ('save Post ');

?>

 

8. configure routing rules and use the index method of the posts controller as the access address of the root directory.

 

In app/Config/routes. php, find

 

Router: connect ('/', array ('controller' => 'pages', 'Action' => 'display', 'home '));

Changed to: Router: connect ('/', array ('controller' => 'posts', 'Action' => 'index '));

 

9. open the address http: // localhost/cakephp/to access the home page, and add, delete, modify, and query the post table.

On the first day, I learned how to add, delete, modify, and query cakephp and how to modify the template suffix. I have a general understanding that cakephp works in MVC mode. The following figure shows the cakephp request.
