Installing CakePHP
Download the latest stable version of CakePHP from the link below. Currently the latest version 1.3.10.
Unzip the file and FTP to your website.
There is no setup except for entering your MySQL connection details. I also had to configure my Apache Server for
LoadModule rewrite_module modules/mod_rewrite.so # uncomment in httpd.conf
#Also in httpd.conf
Also find AllowOverride None
Should be:
AllowOverride All

CakePHP Create a Simple Blog Example
CalePHP Hello World Example
This is a simplified version of the example on the CakePHP website. It does the least possible for simplicity it will just list your blog postings
Stage 0) Set up your Data
MySQL
/* Use PHPMyAdmin or equivalent to set up your 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 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 (Squidoo useful for tutorials', 'Learn about Squidoo', NOW());
INSERT INTO posts (title,body,created)
VALUES ('Another Title', 'Put what you like here', NOW());
CREATE TABLE posts (
id INT UNSIGNED AUTO_INCREMENT PRIMARY KEY,
title VARCHAR(50),
body TEXT,
created DATETIME DEFAULT NULL,
modified DATETIME DEFAULT NULL
);
/* 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 (Squidoo useful for tutorials', 'Learn about Squidoo', NOW());
INSERT INTO posts (title,body,created)
VALUES ('Another Title', 'Put what you like here', NOW());
Stage 1) Create your Model
<?php
// /app/models/post.php
class Post extends AppModel
{
var $name = 'Post';
}
?>
// /app/models/post.php
class Post extends AppModel
{
var $name = 'Post';
}
?>
Stage 2) Create Your Controller
<?php
// /controllers/posts_controller.php
class PostsController extends AppController
{
var $helpers = array ('Html','Form');
var $name = 'Posts';
function index() {
$this->set('posts', $this->Post->find('all'));
}
}
?>
// /controllers/posts_controller.php
class PostsController extends AppController
{
var $helpers = array ('Html','Form');
var $name = 'Posts';
function index() {
$this->set('posts', $this->Post->find('all'));
}
}
?>
Stage 3) Create Your View
<!-- File: /app/views/posts/index.ctp -->
<h1>Blog posts</h1>
<table>
<tr>
<th>Id</th>
<th>Title</th>
<th>Created</th>
</tr>
<!-- Here is where we loop through our $posts array, printing out post info -->
<?php foreach ($posts as $post): ?>
<tr>
<td><?php echo $post['Post']['id']; ?></td>
<td>
<?php echo $this->Html->link($post['Post']['title'],
array('controller' => 'posts', 'action' => 'view', $post['Post']['id'])); ?>
</td>
<td><?php echo $post['Post']['created']; ?></td>
</tr>
<?php endforeach; ?>
</table>
<h1>Blog posts</h1>
<table>
<tr>
<th>Id</th>
<th>Title</th>
<th>Created</th>
</tr>
<!-- Here is where we loop through our $posts array, printing out post info -->
<?php foreach ($posts as $post): ?>
<tr>
<td><?php echo $post['Post']['id']; ?></td>
<td>
<?php echo $this->Html->link($post['Post']['title'],
array('controller' => 'posts', 'action' => 'view', $post['Post']['id'])); ?>
</td>
<td><?php echo $post['Post']['created']; ?></td>
</tr>
<?php endforeach; ?>
</table>
Stage 4) Run your Blog

MVC : Model View Controller
What does MVC Mean?
(Model View Controller) MVC expresses the separation of a software architecture into three distinct elements. The 'Model' is how the underlying data is structured. The 'View' is what is presented to the user or consumer. The 'Controller' is the element that performs the processing.
The model manages the behavior and data of the application domain, responds to requests for information about its state (usually from the view), and responds to instructions to change state (usually from the controller). In event-driven systems, the model notifies observers (usually views) when the information changes so that they can react.
The view renders the model into a form suitable for interaction, typically a user interface element. Multiple views can exist for a single model for different purposes. A viewport typically has a one to one correspondence with a display surface and knows how to render to it.
The controller receives user input and initiates a response by making calls on model objects. A controller accepts input from the user and instructs the model and viewport to perform actions based on that input.
