1 Programming in PHP Have you Cake? Presenter: Nguyen Thanh Hai Mar. 30 th, 2014

2 Agenda Introduction Components needed Model-View-Controller Cake convention Relationship between Models Validation of data Baking the cake Hands on Conclusion

3 Introduction Rapid development framework for PHP Using design patterns: MVC and ORM Similar to Zend and Ruby on Rails (ROR) framework Scaffolding support - 2 line code for CRUD Easier to maintain Reduces development costs Write less code Current version (Stable: , 2.4.6, 3.0.0)

4 Introduction (cont) Example of sites done using CakePHP CIT: National project of Dr. Le Quyet Thang CIT: The first research project of students in 2011 Cooperative projects: Quan ly ke hoach kinh doanh tap doan Viettel 4/27 theses in 2011, 2012: Quan ly thuc hanh, Quan ly thu vien, Many research topics of students in Semester 3

5 Components to run Cake Database - MySQL Apache PHP Recommended Installation Xampp - 10 mins installation plus configuration :)

6 Model-view-controller In short MVC Multi-tier architecture Decoupling of program Business logic Data presentation User interaction Benefits Reduce complexity in architectural design Increase flexibility and reuse.

7 Model-View-Controller (cont) Model domain-specific representation of the information View Renders the model into a form suitable for interaction Controller Processes and responds to events To make use of this capability, convention needs to be followed

8 Convention - Filename Controller KissesAndHugsController -> kisses_and_hugs_controller.php Model OptionValue -> option_value.php Component MyHandy -> my_handy.php Helper BestHelperEver -> best_helper_ever.php

9 Convention - Model Model class names are singular Capitalized for single-word models Person, Monkey UpperCamelCased for multi-word models. GlassDoor, LineItem, ReallyNiftyThing many-to-many join tables tags_users Model filenames use a lower-case underscored syntax person.php, line_item.php, really_nifty_thing.php

10 Convention - Model Database tables plural, lower-case underscored syntax people, monkeys, glass_doors, line_items, really_nifty_things

11 Example of model file - school.php <?php class School extends AppModel { var $name = 'School'; var $validate = array( //'id' => VALID_NUMBER, 'schname' => VALID_NOT_EMPTY, ); }?>

12 Convention - Controller Class names are plural Capitalized for single-word controllers, and UpperCamelCased for multi-word controllers. Controller file names use a lower-case underscored syntax For protected member visibility, controller action names should be prepended with '-. For private member visibility, controller action names should be prepended with ' '.

13 Example of controller - schools_controller.php <? class SchoolsController extends AppController { var $name = 'Schools'; var $scaffold; function beforefilter(){ //check if user login and user login type } }?>

14 Convention (more) More convention for cake Helpers Vendors Components

15 Convention - Views Named after actions they display. Name the view file after action name, in lowercase. You can force an action to render a specific view by calling $this->render( create'); at the end of your action.

16 Model Relationship 3 types of relationship between model Has One Has Many Has And Belong To Many (HATBM)

17 Built-in validation for data VALID_NOT_EMPTY VALID_ VALID_NUMBER VALID_YEAR Regex allowed

18 Baking cake Create class files of model, controller and view files effortlessly Automate the creation of model class, validation for attributes and relationship. Able to bake controllers and views. Run terminal window to execute bake script. Steps Go to place where you can to create the application via cd command /usr/bin/php {cakehome}/scripts/bake.php -help

19 Setting up cake Copy and paste into www or htdocs

20 An example CREATE TABLE IF NOT EXISTS `majors` ( `id` int(11) NOT NULL, `class_name` varchar(30) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1; CREATE TABLE IF NOT EXISTS `students` ( `id` int(11) NOT NULL, `name` varchar(30) NOT NULL, `password` varchar(30) NOT NULL, `birthday` date NOT NULL, `major_id` int(11) NOT NULL ) ENGINE=InnoDB DEFAULT CHARSET=latin1;

21 Hands On Demo

22 Conclusion Easy to use Quick implementation Quick to deploy Free =) Once you use it, you want more of it
