  1. Zend Framework 101 Shaun Farrell Thursday, July 21, 11

  2. Zend Framework (ZF) Open-Source Software (OSS) New BSD License Contributor

    License Agreement (CLA) Zend Technologies Development Started in Summer 2005 0.1.0 Released in March 2006 1.11.9 Released in July 2011 Thursday, July 21, 11
  3. Fully Object-Oriented (PHP5) Requires PHP 5.2.4 or Later Use-at-Will Architecture

    Loosely Coupled Components Component vs Full Stack Framework Coding Standards, Code Coverage (80%) 80% of common tasks, 20% Business Logic Thursday, July 21, 11
  4. ZF Structure Thursday, July 21, 11

  5. General Structure Controllers Models Configuration Files Layouts Views Forms Modules

    Public Folder - Font Controller Library Services Thursday, July 21, 11
  6. Views Display templates. No Logic in here There are helper

    methods like partialLoop, baseUrl etc.. Thursday, July 21, 11
  7. Models Model folder is Auto-loaded by Zend_Application. DbTable and Mappers

    are also auto-loaded. Data Mapper Design Pattern There is no Zend_Model OO Classes! Thursday, July 21, 11
  8. Controllers How the request is controlled. Controllers have actions indexAction(),

    bookAction(), authorAction() Fat vs Skinny Move Logic to Service Classes Thursday, July 21, 11
  9. Configs Store application specific configurations Loaded at request via FrontController

    Custom Configs Vs Resource configs Thursday, July 21, 11
  10. Layouts View Templates Can have as many as you want

    Like Master Templates in .net Thursday, July 21, 11
  11. Forms Class structured Uses Zend_Form Thursday, July 21, 11

  12. Modules Separation of your Application Default Module vs No Default

    Module Recommend Default Module Can have as many as you want Can use or share other Models etc. Uncouple them! Thursday, July 21, 11
  13. Public Folder - FC Holds your Front Controller All requests

    come in through Index.php Public folder is your Web root! Put assets here (css, images, js etc.) Thursday, July 21, 11
  14. Library Location of ZF Libs and other Libs. Custom Libraries

    - Keep same format. Thursday, July 21, 11
  15. Services Auto-loaded by Zend_Autoloader Can be used for anything. Example

    Usage - Image Classes, other Common scripts. Thursday, July 21, 11
  16. Modules Blog example.com/blog Default example.com/ Thursday, July 21, 11

  17. ZF Routing Thursday, July 21, 11

  18. Everything comes in through index.php in your public folder This

    is your FrontController FrontController loads your Configs and then Runs Zend_Application which auto-loads everything Then the request is dispatched out to the correct module/controller/action or route. It’s not that simple! Thursday, July 21, 11

  20. FC handles incoming request Router maps urls to module, controller,

    action Dispatcher dispatches the request Action controller runs logic Request passed to request object Output response Thursday, July 21, 11
  21. Logic can be run at multiple points in a dispatch!

    Thursday, July 21, 11
  22. FrontController Plugins routeStartup() is called before Zend_Controller_Front calls on the

    router to evaluate the request against the registered routes. routeShutdown() is called after the router finishes routing the request. dispatchLoopStartup() is called before Zend_Controller_Front enters its dispatch loop. preDispatch() is called before an action is dispatched by the dispatcher. This callback allows for proxy or filter behavior. By altering the request and resetting its dispatched flag (via Zend_Controller_Request_Abstract::setDispatched(false)), the current action may be skipped and/or replaced. postDispatch() is called after an action is dispatched by the dispatcher. This callback allows for proxy or filter behavior. By altering the request and resetting its dispatched flag (via Zend_Controller_Request_Abstract::setDispatched(false)), a new action may be specified for dispatching. dispatchLoopShutdown() is called after Zend_Controller_Front exits its dispatch loop.

  23. Standard Router :controller/:action http://www.loc.gov/pictures/collections/ Would load pictures controller, and collections

    action :module/:controller/:action http://www.loc.gov/admin/pictures/add Would load admin module, pictures controller, and add action Thursday, July 21, 11
  24. Custom Routes Zend_Controller_Router_Route Zend_Controller_Router_Route_Static Zend_Controller_Router_Route_Regex Zend_Controller_Router_Route_Hostname Zend_Controller_Router_Route_Chain Zend_Controller_Router_Rewrite http://framework.zend.com/manual/en/ zend.controller.router.html

  25. ZF Design Patterns (JUST A FEW) Thursday, July 21, 11

  26. MVC Separation of Code. Splits the user interface interaction into

    three distinct roles. http://martinfowler.com/eaaCatalog/ modelViewController.html Thursday, July 21, 11
  27. Data Mapper A layer of mappers that moves data between

    objects and a database while keeping them independent of each other and the mapper itself http://martinfowler.com/eaaCatalog/ dataMapper.html Thursday, July 21, 11
  28. Table Data Gateway An object that acts as a “Gateway”

    to a database table. One instance handles all the rows in the table. Table Data Gateway Vs. Data Mapper http://martinfowler.com/eaaCatalog/ tableDataGateway.html Thursday, July 21, 11
  29. Front Controller A controller handles all the request for a

    web site. http://martinfowler.com/eaaCatalog/ frontController.html Thursday, July 21, 11
  30. Composite View & Two Step View 2 Step - Turns

    domain data into HTML in two steps: first by forming some kin of logical page, then rendering the logical page into HTML. Layouts & Views Thursday, July 21, 11
  31. Decorators Allows you to dynamically add behavior to an existing

    object. Zend_Form - changing the markup. http://en.wikipedia.org/wiki/Decorator_pattern Thursday, July 21, 11
