introduction
This article is a continuation of the previous blog that I published titled “Model-View-Controller (MVC Framework)”. For those who has not read it yet please refer to this link: http://devfun-lab.com/1061 that contains the introduction of MVC, what is MVC, where and when can we use MVC, and a brief introduction on what are the sample language and framework that uses MVC.
In this article, we will be focusing on the sample languages and framework where it uses MVC. For this month, our topic will be MVC Framework: Cake PHP version 3. This article is more of a hands-on activity where you can follow and build a basic cake PHP app. Credits to “Traversy Media” on YouTube as it is where I based my basic understanding in cake PHP as they gave a very good example on the app which I will showing today.

Today I will be introducing the topic of the Model Control View framework (MVC) framework. In this short research paper, we will be discussing the following items:
Why Cake PHP?
- Model, view, controller architecture.
- Application scaffolding
- Code generation via bake
- Free & open source
- Access control list and authentication
- Validation model data
- Router for mapping url
- Built in email, cookies, security, session, HTML Helpers
Pre-requisite before learning Cake PHP Framework.
Like in all development tools, before using a framework, one must learn the basic of the tool. For this instance, before learning Cake PHP, one must first learn the Native PHP.
Install XAMP/WAMP and composer
Installing Cake PHP
Run cmd on htdocs folder and run the create script
php composer.phar create-project –prefer-dist cakephp/app [my_app_name]
Successful installation
Usual error:
| Reason |
extension not set |
| Fix by Changing Php.ini |
From: ;extension=php_intl.dll |
| To: extension=php_intl.dll |
Set up DB connection
Open config>app.php
| Database Username |
Username access credential that has access to the Database. |
| Database Password |
Password for the Username that has been used. |
| Database Name |
Name of the database where Cake PHP will connect to. |
Open config>Successful connection
Cake Bake
- Bake command for cake creates the scaffolding for MVC
- To run Bake Command, Go to cake project root folder and run cmd prompt.
- Bin/cake bake all [table Name]
Folder Structure
| Model
|
Responsible for single entity |
myLogin>>src>>Model>>Entity |
| Responsible for whole table |
myLogin>>src>>Model>>TabLe |
| Controller |
Connects the View to the Model |
myLogin>>src>>Controller |
| View |
GUI of the Tool |
myLogin>>src>>Template. |
Key points
| View default layout is in: |
myLogin>>src>>Template>>Layout>>Default.ctp |
| Redirection based on return |
$this->redirect([‘controller’ => ‘controller that will be used’ , ‘action’ => ‘index’]) |
| If there is no [‘controller’ ], cake will assume that you are using the current controller you are in: |
$this->redirect(‘action’ => ‘index’]) |
| If there is no [ ‘action’], cake will assume that you are using the index function |
$this->redirect([‘controller’ => ‘controller that will be used’]) |
| Usually used for redirection Html helper |
Html->link(‘[link label]’, [‘controller’ => ‘controller that will be used’, ‘action’ => ‘function in the controller’]) ?> |
| Html->link(‘Logout’, [‘controller’ => ‘users’, ‘action’ => ‘logout’]) ?> |
Data Manipulation Pull to from Model to Controller
| Pull all |
$users = $this->Users->find()->all(); |
| Pull with where |
$users = $this->Users->find()->where([‘name’ => ‘rey’])->all(); |
| Pull with multiple where |
$users = $this->Users->find()->where([ ‘name’ => ‘rey’, ‘email’ => ‘norbert@gmail.com’] ) ‘])->all();
|
Data Manipulation Pull to from Controller to View
| Pull with multiple where – Set data after pulling – In Controller |
$this->set(compact(‘users’)); |
| Using different variable name in front end – In Controller |
$this->set(‘newUsers’, $users); |
Data Manipulation Pull to from View to Controller
| Create from with input |
Form->input(‘name’);?>
Form->submit(‘Get Data’, array(‘class’ => ‘button’));?> |
| On controller make a data request |
if($this->request->is(‘post’)){ $data = $this->request->data; }
|
