    1. 1. Zend Framework Introduction by Susheel Kumar Sharma
    2. 2. Zend Framework Introduction <ul><li>Open Source Framework </li></ul><ul><li>100% Object-Oriented Code </li></ul><ul><li>Use-At-Will </li></ul><ul><li>  MVC Pattern </li></ul>
    3. 3. MVC <ul><li>Model - data, web services, feeds, etc. </li></ul><ul><li>View - The display returned to the user. </li></ul><ul><li>Controller - Manages the request environment, and determines what happens. </li></ul>
    4. 4. MVC Cont..
    5. 5. MVC Cont… <ul><li>Controller <-> View Controller and View can interact </li></ul><ul><li>Controller <-> Model Controller can pull data from the model for decisioning, or push data to the model </li></ul><ul><li>View <- Model View can access the model to retrieve data, but not write to it. </li></ul>
    6. 6. Installation Zend Framework Cont.. <ul><li>By Installing Zend Server </li></ul><ul><li>Manual Installation </li></ul>
    7. 7. Installation Zend Framework Cont.. <ul><li>Manual Installation </li></ul><ul><li>1.Check php is available from any directory </li></ul><ul><li>C:Userscompare>php –I </li></ul><ul><li>2.If not, set path for php.exe in System Environment Variable </li></ul><ul><li>a)Find your php installation directory - This can generally be found in one of the following places: </li></ul><ul><li>C:php </li></ul><ul><li>C:xamppphp </li></ul><ul><li>b)Go to -> My Computer -> (Right Click)Properties </li></ul><ul><li>-> Advanced -> Environment Variables -> System Variables -> (Select)Path -> Edit -> Variable Value(Paste) -> Ok </li></ul>
    8. 8. Installation Zend Framework Cont.. 3.Copy zf.bat, zf.php from ZendFrameworkbin and paste zf.bat, zf.php to C:php or C:xamppphp 4.Set up Zend Framework library to system PHP include_path a) Open php.ini in an editor b) Find include_path c) Add Zend Framework library e.g. include_path = &quot;.;G:xamppphppear;G:dataZendFrameworklibrary“ 5. Run command C:Userscompare>zf show version Zend Framework Version: 1.11.2
    9. 9. Create Project 1.Go to directory where you want to create project e.g. C:Userscompare>cd .. C:Users>cd .. C:>G: G:>cd xampphtdocs G:xampphtdocs> 2. Run command G:xampphtdocs> zf create project trainingtestproject Creating project at G:/xampp/htdocs/trainingtestproject Note: This command created a web project, for more information setting up your V HOST, please see docs/README

    12. 12. Main Artifacts <ul><li>Bootstrap </li></ul><ul><li>Configuration </li></ul><ul><li>Action Controllers </li></ul><ul><li>Views </li></ul>
    13. 13. The Bootstrap <ul><li>Bootstrap class defines what resources and components to initialize </li></ul><ul><li>By default, Zend Framework's Front Controller is initialized </li></ul><ul><li>It uses the application/controllers/ as the default directory in which to look for action controllers </li></ul><ul><li>The class looks like the following: </li></ul><ul><li>// application/Bootstrap.php </li></ul><ul><li>class Bootstrap extends Zend_Application_Bootstrap_Bootstrap </li></ul><ul><li>{ </li></ul><ul><li>} </li></ul>
    14. 14. Configuration <ul><li>Zend Framework is itself configuration less, need to configure application. </li></ul><ul><li>The default configuration is placed in application/configs/application.ini </li></ul><ul><li>Contains some basic directives for setting PHP environment  </li></ul><ul><li>It looks as follows: </li></ul>
    15. 15. Configuration Cont.. ; application/configs/application.ini [production] phpSettings.display_startup_errors = 0 phpSettings.display_errors = 0 includePaths.library = APPLICATION_PATH &quot;/../library&quot; bootstrap.path = APPLICATION_PATH &quot;/Bootstrap.php&quot; bootstrap.class = &quot;Bootstrap&quot; appnamespace = &quot;Application&quot; resources.frontController.controllerDirectory = APPLICATION_PATH &quot;/controllers&quot; resources.frontController.params.displayExceptions = 0 [staging : production]   [testing : production] phpSettings.display_startup_errors = 1 phpSettings.display_errors = 1 [development : production] phpSettings.display_startup_errors = 1 phpSettings.display_errors = 1
    16. 16. Action Controllers <ul><li>action controllers contain application workflow, do mapping requests to the appropriate models and views. </li></ul><ul><li>action controller should have one or more methods ending in “Action” </li></ul><ul><li>  methods may then be requested via the web </li></ul><ul><li>Zend Framework URLs follow the schema /controller/action </li></ul><ul><li>&quot;controller&quot; maps to the action controller name (minus the &quot;Controller&quot; suffix) and &quot;action&quot; maps to an action method (minus the &quot;Action&quot; suffix) </li></ul><ul><li>need an IndexController, which is a fallback controller and which also serves the home page of the site </li></ul><ul><li>ErrorController, which is used to indicate things such as HTTP 404 errors (controller or action not found) and HTTP 500 errors (application errors) </li></ul>
    17. 17. Action Controllers Cont.. <ul><li>The default IndexController is as follows: </li></ul><ul><li>// application/controllers/IndexController.php </li></ul><ul><li>class IndexController extends Zend_Controller_Action </li></ul><ul><li>{ </li></ul><ul><li>     public function init() </li></ul><ul><li>     { </li></ul><ul><li>         /* Initialize action controller here */ </li></ul><ul><li>     } </li></ul><ul><li>     public function indexAction() </li></ul><ul><li>     { </li></ul><ul><li>         // action body </li></ul><ul><li>     } </li></ul><ul><li>} </li></ul>
    18. 18. Action Controllers Cont.. <ul><li>ErrorController is as follows: </li></ul><ul><li>// application/controllers/ErrorController.php </li></ul><ul><li>class ErrorController extends Zend_Controller_Action </li></ul><ul><li>{ </li></ul><ul><li>     public function errorAction() </li></ul><ul><li>     { </li></ul><ul><li>         $errors = $this->_getParam('error_handler'); </li></ul><ul><li>         switch ($errors->type) { </li></ul><ul><li>             case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_ROUTE: </li></ul><ul><li>             case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_CONTROLLE </li></ul><ul><li>R: </li></ul><ul><li>            case Zend_Controller_Plugin_ErrorHandler::EXCEPTION_NO_ACTION: </li></ul><ul><li>                 // 404 error -- controller or action not found </li></ul><ul><li>                 $this->getResponse()->setHttpResponseCode(404); </li></ul><ul><li>                 $this->view->message = 'Page not found'; </li></ul><ul><li>                 break; </li></ul>
    19. 19.              default:                  // application error                  $this->getResponse()->setHttpResponseCode(500);                  $this->view->message = 'Application error';                  break;          }           $this->view->exception = $errors->exception;          $this->view->request   = $errors->request;      } }
    20. 20. Views <ul><li>Written in plain old PHP </li></ul><ul><li>View scripts are placed in application/views/scripts/ </li></ul><ul><li>They are further categorized using the controller names </li></ul><ul><li>We have an IndexController and an ErrorController </li></ul><ul><li>Thus we have corresponding  index/ and error/  </li></ul><ul><li>subdirectories within view scripts directory </li></ul><ul><li>We thus have the view scripts index/index.phtml  </li></ul><ul><li>and error/error.phtml </li></ul><ul><li>The following is what we install by default for the index/index.phtml view script: </li></ul>
