Zend Framework In Action Code Download
Katja Gains
we are trying to build an application using the zend framework and have the following problem: "Some controller actions are called twice. This means that the actions gets called, finishes its execution and then gets called again".
try and use a debugger ( XDebug for example ) to see how your code is runned.focus on the dispatcher, something must have happened and the request action is not set as dispatched so it gets runned again.
We shall show a confirmation form when the user clicks delete, and if they thenclick "yes", we will do the deletion. As the form is trivial, we'll code itdirectly into our view (zend-form is, after all, optional!).
But if you really want to learn with a framework, you should consider a micro framework instead of a full blown one. Slim has a very small, clean and thoroughly tested code base and it should be ideal for learning. I haven't played around with any other micro framework, you should do your own research and decide which one is better for you.
Zend Framework is like a bunch of independent libraries which together works like a framework. It is very hard to develop something at the same time decoupled and "easy to use". For "easy to use" I mean doing complex things with few lines of code.
So, starting with Zend is harder then other frameworks, like CakePHP. But I it also easier extends and customize your application with no dirty codes. Zend also follows standards and design patterns all over its code, so once you read the framework code, you can guess what's going on.
Like F@bio I'm a little confused about the difference between plugins and action helpers. As I understand it, action helpers are for more on demand functionality, while plugins are for things that you'd want to use on every single page, such as authentication for a private system, or some view initialisation code. Is that the case?
Starting with Zend Framework version 2.5, components are split into independently versioned packages and zendframework/zendframework is converted into a Composer meta-package. Framework components introduced after the split are not added to the meta-package.
While zendframework/zendframework meta-package release version remains at 3.0.0, it will instruct Composer to install latest compatible versions of the framework components, as per the semantic versioning. Such that zend-mvc component will be installed at its current version 3.1.1, zend-servicemanager at version 3.3.0 and zend-form at version 2.10.2.
Controller is the main entry to Zend Framework application.[6] The front controller handler is main hub for accepting requests and running the accurate actions as requested by the commands. The whole process of requesting and reacting is routing and dispatching (which basically means calling correct methods in a class) which determines the functionality of the code.[6] This is implemented by Zend_Controller_Router_- Interface.[6] The router functionality is to find which actions need to be run and on contrary dispatcher runs those requested actions.[6] The controller in Zend Framework is connected in a diverse array of structural directories, which provides a support to efficient routing.[6] The main entry point and the command controller is the Zend_Controller_Front, this works as a foundation which delegates the work received and sent. The request is shaped and encapsulated with an instance of Zend Controller Request HTTP, as a provider of access to HTTP requests.[6] The HTTP hold all the superglobals of the framework ($_GET, $_POST, $_COOKIE, $_SERVER, and $_ENV) with their relevant paths. Moreover, the controller also provides getParam() functions which enables collection of requested variables.
Zend Framework provides the view framework to our project and controller and actions are automatically provided to our application. Inside the Zend Framework in view folder we observe the following folders.[4]
There are various Zend Framework components that can be used to display data on the Employee Administration page. The framework doesn't manadate a particular model. This tutorial uses a class that inherits Zend_Db_Table's database interaction methods. The tutorial also uses a data mapper class to map this data to a model used in the application.
Currently, we are in IndexController.php and we are about to add tabs to the extension. Instead of adding the tabs definition code to each action (for the form, list, and toolbar), we can specify the tabs once in the init() method and avoid code duplication. The init() method runs before action methods. Change the method so that it looks as follows:
Enough abstract, let's dig into what the framework's controller is really doing. All HTTP requests come in through a single point. The way that the request gets routed all depends on the request's parameters. The controller parameter determines which controller to use. The action parameter determines which function to call within the controller. The defaults are, controller='default' and action='view' . In order for the controller to handle the various actions, it must implement a method with the following naming scheme: public function ACTION_action() where ACTION is the value of the action parameter. If the action method returns a string, then the controller will print the header and footer around the string, otherwise the controller won't do anything after the action method is called. Returning void or false is useful for when you really have to customize output or want to avoid printing header/footer altogether (e.g. web service response). Of course, all security checks are executed before the action method to make sure the user is logged in and has the appropriate capabilities. For more information on the controller, read local/mr/docs, view the source code of local/mr/framework/controller/*.
When VuFind first adopted Zend Framework, it needed a method for developing command line utilities. At that point in time, there was really only one logical choice: the zend-console functionality built into the monolithic framework.
The new 0.6.3 stable release of symfony is there, up and running, and it is expecting your download. It is not a major release, but it fixes some bugs and brings some small enhancements. As it doesn't break BC, there is no reason why you shouldn't upgrade. \n\nSo open a CLI and simply type:\n\n$ pear upgrade symfony\/symfony-stable\n\n\nWith this release, you will benefit from the efforts made by the symfony developers during the past two months. Here is a quick changelog:\n\n
- \n
- calendar language files update (pl, zh, nl, no, it)\n
- new options for the sfFillInFilter filter\n
- major sfWebDebug refactoring (no more dependency on prototype)\n
- position option to stylesheets in view.yml\n
- native support for JSON\/AJAX actions\n
- better exception layout\n
- new sfPropelUniqueValidator validator\n
- new component and partial cache\n
- updated creole and propel\n
- zend framework and ez components bridges\n
- new hooks in admin generator generated classes\n
- better date support in admin generator\n
- new project control panel for CLI replacement in development\n
- lot of small tweaks and enhancements in admin generator\n
- lot of bugs fixes and small enhancements\n\n\nThere are two warnings about the use of the 0.6.3:\n\n
- \n
- If you use i18n Propel support in your schema.xml or if you have problems building you Propel model\/sql (error thrown : \"XML schema file (PATH\/config\/schema.xml) does not validate\"), you can add a propel.schema.validate = false at the end of your config\/propel.ini file. This setting is by default for all new projects.\n
- Actions in the routing are now case sensitive. If you have a page with an action named fooBar, your action method must be named exactly executeFooBar.\n\n\nFor more details about the 121 tickets closed since 0.6.2, you can read the custom trac report or the weekly dev news in the wiki.\n","datePublished":"2006-06-23T17:19:06+02:00","dateModified":"2011-03-04T15:08:04+01:00","author":"@type":"Person","name":"Francois Zaninotto","publisher":"@type":"Organization","name":"Symfony","logo":"@type":"ImageObject","url":"\/images\/logos\/sf-positive.svg"} Symfony footer Thanks Pierre Trollé for being a Symfony contributor
Posts about using the PHP framework Zend FrameworkUsing The Zend Framework FlashMessenger14th August 2011 - 8 minutes read timeThe FlashMessenger in Zend Framework has a bit of an odd name as it has nothing to do with Adobe Flash at all. It is a controller action helper defined in the class Zend_Controller_Action_Helper_FlashMessenger, which is used to store and retrive messages that are temporarily stored in the user's session. This is useful if you want to provide form validation and redirection at the same time as you can print out messages after the page has been loaded. If you are familiar with Drupal then this class acts in the same kind of way as the drupal_set_messages() function.
