Zend Framework 1.9 Setup & Using Zend_Tool
- 1. Beginning Zend Framework Or: How I learned to stop worrying and love the framework. Part 1: Setting up
- 2. Preparing Zend Framework Download ZF1.9 svn co http://framework.zend.com/svn/framework/standard/tags/release-1.9.1/library/Zend Add directory containing Zend to php.ini as part of the path.
- 3. Alternately, check out the framework into your pear directory.
- 4. Preparing ZF Contd. Check out bin (Zend Tool) svn co http://framework.zend.com/svn/framework/standard/tags/release-1.9.1/bin Copy zf.php and zf.sh to a directory in your path (/usr/bin)
- 5. Rename zf.sh to zf and make it executable
- 6. Using Zend_Tool to set up your project Create a directory to house your projects mkdir projects Enter directory cd projects Create a project using the zf script zf create project {projectname}
- 7. Add project to apache This can vary widely with OS and version, so you're mostly on your own.
- 8. Make the DocumentRoot the “public” directory within your {projectname} directory.
- 9. After reloading apache, you should be able to go to the site you just set up and see the default zend framework page!
- 10. Normal Application Setup Normally we would have the domain set up to point directly to the “public” directory Keeps php code from being directly accessible
- 11. NO php should go in public folder unless it’s simple and framework is overkill for it Except for index.php
- 12. Directory Structure /application application files…more in a moment /library framework files ( /library/Zend )
- 13. Extra classes/libraries used by the app /public index.php, html/js/images/etc, anything that should be directly accessible by the browser /tests unit tests… another time maybe
- 14. Application Directory Bootstrap.php Specific application – framework setup configs Application .ini file (soon) controllers Holds controller classes (gasp!) models Holds model classes (double-gasp!) views You get one guess what goes in here…
- 15. Wrong, not classes, simple php+html files.
- 16. index.php Prepares include path
- 18. Load & run bootstrap
- 19. Create a database/table Use whatever tools you're used to CREATE TABLE `user` ( `user_id` INT NOT NULL AUTO_INCREMENT , `username` VARCHAR( 255 ) NOT NULL , `email` VARCHAR( 128 ) NOT NULL , `password` VARCHAR( 32 ) NOT NULL , `salt` VARCHAR( 32 ) NOT NULL , `api_key` VARCHAR( 32 ) NOT NULL , `api_secret` VARCHAR( 32 ) NOT NULL , `user_type` TINYINT NOT NULL , PRIMARY KEY ( `user_id` ), UNIQUE KEY `username` (`username`) )
- 20. Add database to app config Edit application/configs/application.ini # Database resources.db.adapter = "pdo_mysql" resources.db.params.host = "localhost" resources.db.params.username = "zfclass" resources.db.params.password = "zfclass" resources.db.params.dbname = "zfclass_ {yourname} " resources.db.isDefaultTableAdapter = true
- 21. application.ini Note that application.ini has multiple sections Production, Staging, Development
- 23. Can be used to specify different databases for different environments
- 24. Configuring the layout What's a layout? 2-step way of providing “overall” layout to your app
- 25. View result html will be placed as “content” in layout
- 26. Layout can house dynamic links for header js, css, etc
- 27. Easily reached from controller or view.
- 28. Layout Contd. Create directory application/layouts and application/layouts/scripts
- 29. Add the following to your application.ini: #layout resources.layout.layout = "layout" resources.layout.layoutPath = APPLICATION_PATH "/layouts/scripts"
- 30. Module Layouts We're making an admin module
- 31. Let's load a specific admin layout for it
- 32. class Plugin_ModuleLayout extends Zend_Controller_Plugin_Abstract { public function preDispatch(Zend_Controller_Request_Abstract $request) { $module = strtolower($request->getParam('module')); $layout = Zend_Layout::getMvcInstance(); if ($layout->getMvcEnabled()) { switch($module) { case 'default': break; default: $layout->setLayoutPath(APPLICATION_PATH . '/modules/' . $module . '/layouts/scripts'); break; } } } } application/plugins/ModuleLayout.php
- 33. Enable the plugin Edit application/Bootstrap.php public function _initLayouts() { Zend_Layout::startMvc(); $this->getPluginResource('frontcontroller') ->getFrontController() ->registerPlugin(new Plugin_ModuleLayout()); }
- 34. Application general layout applications/layouts/scripts/layout.phtml <?php echo $this->doctype() ?> <html> <head> <?php echo $this->headTitle() ?> <?php echo $this->headLink() ?> <?php echo $this->headStyle() ?> <?php echo $this->headScript() ?> </head> <body> <?php echo $this->layout()->content ?> </body> </html>
- 35. Create a User model application/models/DbTable/User.php <?php class Model_DbTable_User extends Zend_Db_Table { protected $_name = 'user'; protected $_primary = 'user_id';
- 36. User Model Cont'd public function addUser($username, $email, $password, $user_type=1) { // generate unique id for the password salt $salt = strtolower(uniqid(rand(), true)); // and finally...one more for their initial api 'secret' key $api_secret_key = strtolower(uniqid(rand(), true)); // create a password hash to save in the database $hashed_pwd = strtolower(md5($password . $salt));
- 37. User Model... $data = array( 'username' => $username, 'email' => $email, 'password' => $hashed_pwd, 'salt' => $salt, 'user_type' => $user_type ); return $this->insert($data); }
- 38. User Model... function updateUser($id, $email, $password=null, $user_type=1) { $where = array('user_id = ?' => (int)$id); $data = array('email' => $email,'user_type'=>$user_type); if ($password !== null){ // generate unique id (again) for the password salt $salt = strtolower(uniqid(rand(), true)); $hashed_pwd = strtolower(md5($password . $salt)); $data['salt']=$salt; $data['password']=$hashed_pwd; } $this->update($data, $where); } } // End class
- 39. Autoloader Allow us to call our model class without having to include it manually In application/Bootstrap.php public function _initAutoload() { $autoloader = new Zend_Application_Module_Autoloader( array( 'namespace'=>'', 'basePath'=>APPLICATION_PATH ) ); return $autoloader; }
- 40. Database Profiling in Firebug! Still in Bootstrap.php public function _initDbprofile() { if($this->getEnvironment() == 'development') { $profiler = new Zend_Db_Profiler_Firebug('All DB Queries'); $db = $this->getPluginResource('db'); $db = $db->getDbAdapter(); $profiler->setEnabled(true); $db->setProfiler($profiler); } }
- 41. URL Structure Defaults to Index controller & Index action /public/{controller}/{action}
- 43. /public/{controller} (assumes Index action)
- 45. /public/admin/user/edit/user_id/3 (admin = module)
- 46. URL Routing You can create your own url structures using Zend_Controller_Router_* Many options Static
- 47. Regex
- 48. Hostname
- 50. Create Admin Module Use zf tool zf create module admin Enable module in application.ini Add to [production] area
- 51. resources.frontController.moduleDirectory = APPLICATION_PATH “/modules” Copy application/layout/scripts/layout.phtml to application/modules/admin/layouts/scripts/layout.phtml
- 52. Create User Controller zf create controller user false admin
- 53. One small bug in zf tool: Rename admin/controllers/UserController.php to Admin_UserController.php
- 54. Rename class in file to Admin_UserController
- 55. Create Action zf create action createuser user 1 admin
- 56. Open User controller file in an editor...
- 57. public function createuserAction() { // create form $form = new Zend_Form(); $form->setMethod('post'); $form->addElement('text','username', array( 'label' =>'User name', 'required'=>true, 'filters'=>array('StringTrim') )); $form->addElement('password','password',array( 'label'=>'Password', 'required'=>true, 'filters'=>array('StringTrim') )); $form->addElement('text','email',array( 'label'=>'Email address', 'required'=>true, 'filters'=>array('StringTrim'), 'validators'=>array('EmailAddress') )); Create a form programatically!
- 58. $form->addElement('captcha','captcha',array( 'label'=>'Enter the letters below', 'required'=>true, 'captcha'=>array( 'captcha'=>'Figlet', 'wordLen'=>5, 'timeout'=>300 ) )); $form->addElement('submit','Save',array( 'ignore'=>true, 'label'=>'Save New User' )); // End form
- 59. $request = $this->getRequest(); if($request->isPost()) { if($form->isValid($request->getPost())) { $data = $form->getValues(); $user = new Model_DbTable_User(); if($user->addUser( $data['username'], $data['email'], $data['password'],2)) // 2 for admin { $this->view->message = 'User created'; } else { $this->view->message = 'Something bad happened.'; } } } $this->view->form = $form; } // End function
- 60. Create View application/modules/admin/views/scripts/user/createuser.php <?php if(isset($this->message)) { ?><h1><?=$this->message ?></h1><?php } ?> Create your new user. <?php $this->form->setAction($this->url()); echo $this->form; ?>
- 61. Create your user! You should now be able to head to http://{yoursite}/admin/user/createuser
- 62. Try it out!
- 63. Create a login action Close the user controller file in your editor
- 64. zf create action login user 1 admin
- 65. Open it back up and find the loginAction method
- 66. public function loginAction() { $form = new Zend_Form(); $form->setMethod('post'); $form->addElement('text','username', array( 'label' =>'User name', 'required'=>true, 'filters'=>array('StringTrim') )); $form->addElement('password','password',array( 'label'=>'Password', 'required'=>true, 'filters'=>array('StringTrim') )); $form->addElement('submit','submit',array( 'label'=>'Login', 'ignore'=>true ));
- 67. $request = $this->getRequest(); $data = $request->getPost(); if($request->isPost() && $form->isValid($data)) { $u = new Model_DbTable_User(); $auth = new Zend_Auth_Adapter_DbTable($u->getAdapter() ,'user','username','password', "MD5(CONCAT(?,salt)) AND user_type=2" ); $auth->setIdentity($data['username'])->setCredential( $data['password'] ); $mainauth = Zend_Auth::getInstance(); $result = $mainauth->authenticate($auth); if($result->isValid()) { $this->view->message = 'You are now logged in.'; } else { $m = $result->getMessages(); $this->view->message = $m[0]; } } $this->view->form = $form; }// End function
- 68. Create a logout action Try the initial part yourself to create the action method. public function logoutAction() { $auth=Zend_Auth::getInstance(); $auth->clearIdentity(); $this->_redirect('/admin/user/login'); }
- 69. Create a login “helper” Edit application/modules/admin/views/helpers/LoginLink.php <?php class Admin_View_Helper_LoginLink extends Zend_View_Helper_Abstract { public function loginLink() { $auth = Zend_Auth::getInstance(); $front = Zend_Controller_Front::getInstance(); if($auth->hasIdentity()) { $username = $auth->getIdentity(); return "Hello, $username [<a href='".$front->getBaseUrl(). "/admin/user/logout'>Logout</a>]"; } else { return '[<a href="'.$front->getBaseUrl(). '/admin/user/login">Login</a>]'; } } }
- 70. Add login helper to layout Edit application/modules/admin/layouts/scripts/layout.phtml Add before echo content: <div id= "login" > <?php echo $this->loginLink();?> </div> This calls the LoginLink helper we created before. Try it out: http://{yoursite}/admin/user/login
- 71. Enough for now If we got this far at the meeting, I'm amazed.
- 72. If not, I can continue at the next meeting.
