Agenda

• Introduction.

• MVC model of cakePHP.

• Folders structure and configurations.

• Controllers, Models and Views.

• Final look on the model.

• A big demo.

Introduction

• Cakephp = Free + OpenSource

• Some Features:

– Active, friendly community

– Compatible with versions 4 and 5 of PHP

– MVC architecture

– Built-in validation

– Works from any web site directory, with little to no Apache configuration involved.

MVC

• CakePHP follows the MVC software design pattern.

– The Model represents the application data

– The View renders a presentation of model data

– The Controller handles and routes requests made by the client

Folder Structure

• Cakephp folder:

– App

– Cake [The core file of cake is here]

– Vendors [ Third-party PHP libraries is here]

– .htaccess

– index.php

– README

Folder Structure (cont.)

• Any application:

CakePHP Conventions

• Conventions => you may feel that it will waste your time while it is actually saving it !! ?

• Because it gives you free functionality

• Conventions for:

– Model and database

– Controller

– Views

CakePHP Conventions (cont.)

• Any PHP file > underscored• Like> any_file.php

• Any Class > CamelCased• Like> anyClass

• Model classes > singular and CamelCased• Like > Person, BigPerson

• Database tables > plural and underscored• Like> persons, big_persons

• Controllers> CamelCased, and end ‘Controller’• Like>PersonController

CakePHP Conventions (cont.)

• Database table: • "people"

• Model class: • "Person", found at /app/models/person.php

• Controller class:• "PeopleController", found at /app/controllers/people_controller.php

• View template, found at• /app/views/people/index.ctp

• Using these conventions, CakePHP knows that a request to http://example.com/people/ maps to a call on the index() function of the PeopleController, where the Person model is automatically available (and automatically tied to the ‘people’ table in the database), and renders to a file. None of these relationships have been configured by any means other than by creating classes and files that you’d need to create anyway

CakeConfiguration

• Configurations needed:

– Database configuration – To be able to connect a database to your application by giving

the parameters needed like username…etc

– Core configuration – Here you configure application settings like sessions,

caching,…etc

– Routes configurations– Here you configure how to parse a Url and what actions to

take then.

Database Configurations

• Can be found at > app/config/database.php

Core Configurations

Variable Description

debug 0 = Production mode. No output.1 = Show errors and warnings.2 = Show errors, warnings, and SQL.3 = Show errors, warnings, SQL, and complete controller dump.

Session.save -php = Use the default PHP session storage.-cake = Store session data in /app/tmp-database = store session data in a database table.

Cache.disable When set to true, caching is disabled site-wide.

Session.table The name of the table (not including any prefix) that stores session information.

Session.*

Routes Configurations

• Found at > app/config/routes.php• Example:

Enough Configurations :)

• Main components structure:

• Controller classes structure

• Model classes structure

• Views structure

Controller classes structure

AppController

Any controller

shares its attributes and parameters with all its children controllers

• Attributes:
