2 INFO Feedback vraag het in de labo s als je feedback wilt op je code Lessen op 5/12 en 12/12 om op 19/12 om 11.00

3 KLEURENCODE GROEN = zelf kunnen schrijven PAARS = code moet je niet zelf kunnen schrijven, maar moet je wel begrijpen, kunnen uitleggen en gebruiken op de juiste plaatsen en hier moet je eventueel een methode moeten kunnen toevoegen indien nodig

5 PROBLEEM PHP code is nu vervuild met require_once op verschillende plaatsen wanneer we bepaalde php files en/of klassen nodig hebben

6 CATEGORYCONTROLLER.PHP <?php class CategoryController extends Controller private $_categorymapper; public function construct () parent:: construct(); require_once(application_path. 'model/categorymapper.php'); $this->_categorymapper = new CategoryMapper();

7 CATEGORYMAPPER.PHP <?php require_once(application_path. 'model/category.php'); class CategoryMapper extends Mapper public function construct() parent:: construct('category', 'Category');

8 OPLOSSING Loader klasse require_once code wordt hierdoor weg gewerkt kan meerdere klassen die elkaar nodig hebben ineens laden

9 CATEGORYCONTROLLER.PHP <?php class CategoryController extends Controller private $_categorymapper; public function construct () parent:: construct(); $this->_categorymapper = $this->_loader->getmodelmapper('category');

10 <?php class Controller protected $_template; protected $_loader; protected $_input; protected $_validator; CONTROLLER.PHP public function construct() // Loader initialiseren $this->_loader = Loader::getInstance(); // input class initialiseren $this->_input = new Input(); $this->_template = new Template(); $this->_validator = new Validator(); $menumapper = $this->_loader->getmodelmapper('menu'); $this->_template->menuitems = $menumapper->getmenuitems(); $this->_template->setpartial('navbar'); $this->_template->setpartial('headermeta'); $this->_template->setpartial('statusmessage'); $this->_template->setpartial('footer'); // haal de statusberichten uit een sessie, dus van een vorige pagina voor de redirect $this->_getstatusmessage();

11 <?php LOADER.PHP class Loader private static $instance = null; private $_model_path = 'model/'; private $_view_path = 'view/'; private $_layout_path = 'view/_layouts/'; private $_partial_path = 'view/_partials/'; private $_controller_path = 'controller/'; private function construct()... public static function getinstance() if (!self::$instance) self::$instance = new self(); return self::$instance;

12 CATEGORYCONTROLLER.PHP <?php class CategoryController extends Controller private $_categorymapper; public function construct () parent:: construct(); $this->_categorymapper = $this->_loader->getmodelmapper('category');

13 LOADER.PHP public function getmodelmapper($modelname) $modelname = ucfirst($modelname); $modelmapper = $modelname. 'Mapper'; $modelfile = $this->_getfile($modelname, $this->_model_path); $modelmapperfile = $this->_getfile($modelmapper, $this->_model_path); require_once($modelfile); require_once($modelmapperfile); try return new $modelmapper(); catch (Exception $e) exit; parameter $modelname = category $modelname = Category $modelmapper = CategoryMapper $modelfile = application/model/category.php $modelmapperfile = application/model/categorymapper.php require_once( application/model/category.php ) require_once( application/model/categorymapper.php ) return new CategoryMapper();

14 LOADER.PHP... private function _getfile($name, $path) $file = APPLICATION_PATH. $path. $this->_addextension($name); if (file_exists($file)) return $file; else error_log("file not found: $file"); exit; private function _addextension($filename) return (substr($filename, -4) == '.php')? $filename : $filename. '.php';

15 CATEGORYCONTROLLER.PHP <?php class CategoryController extends Controller private $_categorymapper; public function construct () parent:: construct(); $this->_categorymapper = $this->_loader->getmodelmapper('category'); $this->_categorymapper = new CategoryMapper();

16 Loader Input AGENDA

17 INPUT Formulieren input, deze moeten we controleren voor de herfstvakantie deden we dit met klassen Validator en Controller Deze klassen gaan we nu integreren in het framework Input klasse Validator klasse

18 Create Read Update Delete CRUD

19 Create Read Update Delete

20 TOT NU TOE... Read bijvoorbeeld overview van alle categorieen tonen

21 VANAF NU ERBIJ... Delete bijvoorbeeld het verwijderen van een bestaande categorie

22 VANAF NU ERBIJ... Create bijvoorbeeld een nieuwe categorie aanmaken Update bijvoorbeeld een bestaande categorie bewerken Hiervoor hebben we formulieren nodig dus input controleren!

23 INPUT 2 belangrijke stappen sanitizen van input trimmen van input en XSS tegen gaan Input klasse validation van input heb ik een -adres ingegeven, heb ik een geldig paswoord ingegeven, heb ik een gebruikersnaam ingegeven die minimum 6 letters lang is,... Validator klasse

24 MESSAGES 2 types messages statusmessage bovenaan de pagina (zowel bij ok als bij nok) fieldmessages onder de velden (zowel bij de ok als bij de nok)

25 statusmessage fieldmessage

26 statusmessage

27 VOORBEELD 1 category/add we vullen amerika in in het categorienaam veld en drukken op de Opslaan knop zonder foutmeldingen, adden lukt
