An introduction to writing a simple Zend Framework MVC application

1. Zend Framework Introduction by Michelangelo van Dam

4. Zend Framework map

7. MVC in action

8. Setting up the virtualhost (Apache) <VirtualHost *:80> ServerName www.example.com ServerAlias example.com DocumentRoot /path/to/example.com/htdocs <Directory /path/to/example.com/htdocs> Options Indexes FollowSymlinks AllowOverride All Order allow,deny Allow from all DirectoryIndex index.php </Directory> SetEnv ENVPHP localhost ErrorLog /path/to/logs/example.com-error_log CustomLog /path/to/logs/example.com-access_log common </VirtualHost>

9. Directory structure app/ default/ <- the &quot;default&quot; application controllers/ <- here you define your controllers ErrorController.php IndexController.php models/ <- this is where your business logic is put views/ <- everything for presentations is put here helpers/ scripts/ index/ index.phtml error/ index.phtml library/ Zend/ <- this is the Zend Framework library htdocs/ <- this is where your bootstrap file is located images/ scripts/ styles/ .htaccess index.php

10. modify apache settings .htaccess RewriteEngine on RewriteRule !(js|ico|gif|jpg|png|css)$ index.php

11. bootstrap file index.php /** * Setup controller */ $controller = Zend_Controller_Front::getInstance(); $controller ->setControllerDirectory( '../application/default/controllers' ); $controller ->throwExceptions( false ); // should be turned on in development time // run! $controller ->dispatch(); require_once 'Zend/Controller/Front.php' ; <?php /** * My new Zend Framework project * * @author Michelangelo van Dam (michelangelo@in2it.be) * @version $Id$ */ set_include_path( '.' . PATH_SEPARATOR . '../library' . PATH_SEPARATOR . '../application/default/models/' . PATH_SEPARATOR . get_include_path() );

12. view script index/index.phtml <?php /** * Default home page view * * @author Micehlangelo van Dam (michelangelo@in2it.be) * @version $Id$ */ echo '<?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot; ?>' ; ?> <! DOCTYPE html PUBLIC &quot;-//W3C//DTD XHTML 1.0 Transitional//EN&quot; &quot;http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd&quot; > < html xmlns = &quot;http://www.w3.org/1999/xhtml&quot; > < head > < meta http-equiv = &quot;Content-Type&quot; content = &quot;text/html; charset=UTF-8&quot; /> < title > New Zend Framework Project </ title > </ head > < body > Hello, world! </ body > </ html >

13. controller IndexController.php <?php /** * IndexController - The default controller class * * @author Michelangelo van Dam (michelangelo@in2it.be) * @version $Id$ */ require_once 'Zend/Controller/Action.php' ; class IndexController extends Zend_Controller_Action { /** * The default action - show the home page */ public function indexAction() { // TODO Auto-generated IndexController::indexAction() action } }

14. that's it !

15. implementing Zend_Layout app/ default/ controllers/ models/ views/ helpers/ layouts/ layout.phtml <- here you define the site layout scripts/ index/ error/ library/ Zend/ htdocs/ images/ scripts/ styles/ .htaccess index.php

16. modifying bootstrap index.php /** * Setup controller */ $controller = Zend_Controller_Front::getInstance(); $controller ->setControllerDirectory( '../application/default/controllers' ); $controller ->throwExceptions( false ); // should be turned on in development time // We enable Zend_Layout Zend_Layout::startMvc(array( 'layoutPath' => '../app/views/layouts' )); // run! $controller ->dispatch(); require_once 'Zend/Controller/Front.php' ; <?php /** * My new Zend Framework project * * @author Michelangelo van Dam (michelangelo@in2it.be) * @version $Id$ */ set_include_path( '.' . PATH_SEPARATOR . '../library' . PATH_SEPARATOR . '../application/default/models/' . PATH_SEPARATOR . get_include_path() );

17. site layout with layout.phtml <?php echo '<?xml version=&quot;1.0&quot; encoding=&quot;UTF-8&quot; ?>' ; ?> <?php echo $this ->doctype( 'XHTML1_TRANSITIONAL' ); ?> < html xmlns = &quot;http://www.w3.org/1999/xhtml&quot; > < head > <?php echo $this ->headMeta()->appendHttpEquiv( 'Content-Type' , 'text/html; Charset=UTF-8' ); ?> <?php echo $this ->headTitle(); ?> </ head > < body > <?php echo $this ->layout()->content; ?> </ body > </ html >

18. modifying index/index.phtml Hello, world!

19. modifying IndexController.php <?php /** * IndexController - The default controller class * * @author Michelangelo van Dam (michelangelo@in2it.be) * @version $Id$ */ require_once 'Zend/Controller/Action.php' ; class IndexController extends Zend_Controller_Action { /** * The default action - show the home page */ public function indexAction() { $this ->headTitle( 'New Zend Framework Application' ); } }

20. Result is the same, but better

24. Thank you... Any Questions ???
