Hello Readers, Here is a small application in CakePHP to add users through which we can Understand "How MVC Architecture works" ? For better understanding of MVC Architecture, I will manually create Model, Controller and Views.

First, You have to create a table in DB to store user data.
 

CREATE TABLE `users` (

  `id` INTEGER(11) NOT NULL AUTO_INCREMENT,

  `name` VARCHAR(255) NOT NULL,

  PRIMARY KEY (`id`)

)

Table names are in plural. Since, it is important to follow CakePHP naming conventions. In the previous tutorial, I explained some basics about CakePHP naming Conventions.

MODEL:

Now, i will create a model for above users table. CakePHP models are located at (Path: /app/models folder). create a file called user.php & paste the following code into it.

<?php

class User extends AppModel {

    var $name = 'User';

}

?>

$name = this variable will be used in our Controller to access the model’s functions.

CONTROLLER:

CakePHP controllers are located at (Path: /app/controllers folder). create a file called user_controller.php & pase the following code into it.

<?php

class UsersController extends AppController {


    var $name = 'User';


    function index() {

        $this->set('users', $this->User->find('all'));

    }


       function add() {

        if (!empty($this->data)) {

            if ($this->User->save($this->data)) {

                $this->Session->setFlash('User has been saved.');

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

            }

        }

}

?>

VIEW:

CakePHP view files are stored at /app/views/folder_name correspond to controller (we will have to create a folder named users in this case). Create a file index.ctp in /app/views/users folder & Copy/paste the following code into index.ctp
 

<h1>Users</h1>

<table>

    <tr>

        <th>Id</th>

        <th>Title</th>

    </tr>


    <?php foreach ($users as $user): ?>

    <tr>

        <td><?php echo $user['User']['id']; ?></td>

        <td>

            <?php echo $html->link($user['User']['name'],

array('controller' => 'users', 'action' => 'view', $user['User']['id'])); ?>

        </td>

    </tr>

    <?php endforeach; ?>

</table>

To test what you have done, Go to command terminal-> Run the server.

then, Open web browser & hit the following URL http://localhost/cake/users)
