Introduction to CakePHP
- 1. CakePHP Framework Cake chefs: Mohamed Samir Moustafa Badawy
- 2. Agenda • Introduction. • MVC model of cakePHP. • Folders structure and configurations. • Controllers, Models and Views. • Final look on the model. • A big demo.
- 3. 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.
- 4. 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
- 7. Folder Structure • Cakephp folder: – App – Cake [The core file of cake is here] – Vendors [ Third-party PHP libraries is here] – .htaccess – index.php – README
- 8. Folder Structure (cont.) • Any application:
- 9. 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
- 10. 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
- 11. 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
- 12. 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.
- 13. Database Configurations • Can be found at > app/config/database.php
- 14. 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.*
- 15. Routes Configurations • Found at > app/config/routes.php • Example:
- 16. Enough Configurations :) • Main components structure: • Controller classes structure • Model classes structure • Views structure
- 17. Controller classes structure Controller AppController Any controller shares its attributes and parameters with all its children controllers
- 18. Controller classes structure • Attributes: • Interacting with views & Model: Model Interaction View Interaction
- 20. Model classes structure • Example:
- 21. Views structure • Example: Header for all pages Page content Footer for all pages
- 22. Final view before the Demo Controller Model View data 2 3 1 6 5 4 Find() Save(data) set(data) Render(view) Logic
- 23. Demo Show time
