Abstract Data Structures ZendCMS

Thu, 22 Sep 2011 10:41:11 GMT

Abstract data structures look at content in a different way. In an abstract system, content is content. The database's primary responsibility is to store and serve this content, not to make sense of it. This is solely the application's job. Let's consider a common example to illustrate how this works. Say your CMS has two modules, one that manages news and one that manages events. On the front end of your site, news articles and events are unique items with unique properties. The key here is to...

Search for Group Photos WritingControllers

Mon, 12 Sep 2011 22:27:34 GMT

Flickr offers a wide variety of photo support and user participation. Users can comment on each other's photos, so it comes as no suprise that Flickr has allowed users to join together into groups that share the same interests. If you're a fan of crazy costumed fans at KISS concerts, you can find others who share their recent Gene Simmons and gang photos on Flickr. Let's see how you can view it by using the Zend_Service_Flickr component. You need the group ID, which you find by doing a search...

Creating a Server WritingControllers

Wed, 07 Sep 2011 17:50:31 GMT

Two main classses, Zend_Rest_Client and Zend_Rest_Server, make up the Zend_Rest component. These classes provide the option to either create a REST client or a server that accepts REST requests. Before you dive into the client and call web services, you'll create your own server, which you'll later use to test the REST client implementations. Looking under the hood, the Zend_Rest_Server class allows you to specify either a method or a complete class that contains the code to process requests....

Creating Textarea Fields WritingControllers

Fri, 02 Sep 2011 14:26:54 GMT

Let's create a textarea, a widely used form element that allows developers to create an input field in which the user has ample amount of space to type in any number of characters. This is a great field if you want the user to type in large amounts of data, such as a personal biography or a short story. To add the element to the form, you use the Zend_Form_Element_TextArea class. Let's use the new Zend_Form_Element_TextArea class to create the update form. The new action will create the update...

Creating the Base Class ZendCMS

Sun, 14 Aug 2011 10:14:09 GMT

Create a new class in this file named CMS_Content_Item_Abstract. Since this class wraps a standard page, you need to add properties for each of the pages table's columns to it. Make all the fields except namespace public. The namespace field will be set on an item level and should be protected so only child classes can change it. Also, add a protected property for the Page model, which will be loaded in the constructor, so it needs to get loaded only once. Once you set these up, add the...

Adding Validation and Filtering WritingControllers

Sat, 13 Aug 2011 01:19:04 GMT

You know that form-submitted data can be validated by using Zend_Form you also know that there are setters such as the setRequired method, which enables you to set a form element as a required form field the user must populate. Now let's see the complete collection of validators and filters that Zend_Form contains. Why validate Validation allows you to check whether the user really did submit data that is properly formatted and meets your application requirements. For example, you might require...

Rendering the Most Recent Pages ZendCMS

Fri, 12 Aug 2011 09:53:06 GMT

To get started, create a new method in the Page model to fetch the most recently created pages. This method will need to fetch the pages in the order that they were created. It then needs to cycle through these pages, opening each one. Finally, it should return these pages as an array that you can pass to the view Listing 6-17 . Listing6-17. ThegetRecentPages Method in application models Page.php public function getRecentPages count 10, namespace 'page' select- gt order 'date_created DESC'...

Integrating ZendTranslate with Your Project ZendCMS

Wed, 10 Aug 2011 11:59:51 GMT

There are many ways to integrate Zend_Translate with your project, but I prefer to create application resources for any kind of generalized configuration like this. This enables you to reuse the resource in any ZF project you work on. To get started, create a new folder in the application folder named lang. Then create two files in this folder source-en.csv and source-es.csv. Note It is not technically necessary to create a language file for your default language. If the translate helper does...

Request Object WritingControllers

Fri, 29 Jul 2011 11:40:35 GMT

Going back to the MVC life cycle, after the controller finishes processing with no errors, it initializes the user interface UI that the user will see, otherwise known as the view. Because the view is a critical component for the controller, the controller automatically creates three objects for immediate use The Request object is covered in this section you'll look at the ViewRenderer and the Response object in Chapter 4 . The Request object handles all incoming user data or any data sent from...

Using REST web services with ZendRest 1 Public Web Services

Wed, 27 Jul 2011 12:04:27 GMT

At the start of this chapter, we mentioned that the various Zend Framework components we'd be working with would include XML but that we wouldn't be needing to deal with it directly. The Zend_Rest section of the manual opens by stating that REST Web Services use service-specific XML formats, which is true, but it needs a little clarification because REST web services don't care whether or not they use XML. Zend_ Rest does use XML as its format of choice, but it's possible to circumvent this if...

Using Item Elements WritingControllers

Wed, 27 Jul 2011 12:02:14 GMT

Channel element information is only half of what Zend_Feed can parse. The second main section of an RSS document are the items syndicated articles contained in the document. Table 7-18 shows the full list of tags the Zend_Feed component supports when parsing the document's data. Using the table, you'll expand on the section's example and parse the two articles contained in the rssexample.xml RSS feed. Table 7-18.

Updating the Bug Record ZendCMS

Mon, 25 Jul 2011 21:38:15 GMT

Now you need to create a method in the Bug model to update an existing record. It will be virtually identical to the createBug method except that you are going to pass the method an ID the primary key , and it is going to find the row to update rather than creating a new one see Listing 4-30 . Listing4-30.

C Case sensitivity Public Web Services

Tue, 05 Jul 2011 23:59:26 GMT

Zend Framework's router and dispatcher are sensitive to the case of action and controller names. This is for a very good reason PHP's function and method names aren't case sensitive, but filenames generally are. This means that there are rules when using capital letters or other word separators as controller names to ensure that the correct class files can be found. For action names, it's important that the correct view script can be found. The following subsections outline the rules for...

Lazy Loading ZendCertification

Tue, 05 Jul 2011 01:10:50 GMT

Prior to PHP 5, instantiating an undefined class, or using one of its methods in a static way would cause a fatal error. This meant that you needed to include all of the class files that you might need, rather than loading them as they were needed just so that you wouldn't forget one or come up with complicated file inclusion mechanisms to reduce the needless processing of external files. To solve this problem, PHP 5 features an autoload facility that makes it possible to implement lazy...

CrossSite Request Forgeries ZendCertification

Mon, 04 Jul 2011 08:41:38 GMT

The HTTP request then causes the victim to execute a particular action based on his or her level of privilege, such as making a purchase or modifying or removing information. Whereas an XSS attack exploits the user's trust in an application, a forged request...

Designing a Database That Can Grow with Your System ZendCMS

Sat, 02 Jul 2011 19:42:40 GMT

The preceding example demonstrated that data can be standardized but did not allow for the fact that not all forms of data can fit into this standard structure. Say, for example, that you needed to add a location to the CMS events. Many news articles could use this field, but many would not. In a simple example like this, the problem may not have any practical impact the articles that don't have a location could simply ignore this field. In a more complex, real-world example, this issue can...

Working with CMS Data ZendCMS

Your job as a CMS developer is to make managing and publishing information as easy as possible. This challenge is compounded by the fact that the information can take many forms on the Web. There are as many solutions to this problem as there are CMSs, each with its own pros and cons. One of the real benefits of developing with a framework like Zend Framework is that you don't have to worry about much of the low-level application logic. The framework provides a standardized API, which you can...

Translating with ZendTranslate Public Web Services

Fri, 01 Jul 2011 13:39:32 GMT

As we've already seen, website translation requires, at a minimum, ensuring that every string that is displayed has a translated version. The most common way to do this is with gettext , which is powerful but fairly complicated. Zend_Translate supports the gettext format but also supports other popular formats such as arrays, CSV, TBX, Qt, XLIFF, and XmlTm. Zend_Translate is also thread-safe, which can be very helpful if you're running a multithreaded web server, such as IIS. Zend_Translate...

Updating the fetchBugs Method to Return a ZendPaginator Adapter ZendCMS

Thu, 30 Jun 2011 22:16:02 GMT

The fetchBugs method that you wrote earlier creates a Zend_Db_Table_Select object, runs the fetchAll method, and then returns the results. Things work a little differently with the paginator since Zend_Paginator runs its own queries, you need to update the fetchBugs method to return an instance of the DbTableSelect adapter. One other thing since the method is no longer returning bugs, you should rename the method to fetchPaginatorAdapter . I always like to name a method so it describes what the...

Thu, 30 Jun 2011 22:15:59 GMT

Now you need to refactor the BugController's listAction one more time to fetch the paginator and pass it to the view. Note that as you develop more with the framework, you will see a pattern emerge where you cycle from the model to the controller to the view, working on all three components simultaneously to build and refactor functionality. You first need to refactor how the controller is handling the request parameters in listAction . This is because the sort and filter criteria are going to...

Whats in it Public Web Services

Mon, 04 Apr 2011 20:18:27 GMT

Zend Framework is composed of many distinct components that can be grouped into six top-level categories. Because it is a complete framework, you have everything you need to build enterprise-ready web applications. However, the system is very flexible and has been designed so that you can pick and choose to use those bits of the framework that are applicable to your situation. Following on from the high-level overview shown earlier in figure 1.3, figure 1.4 lists the main components within each...

Implementing access control 1 Public Web Services

Mon, 04 Apr 2011 13:23:01 GMT

As we discussed in section 7.1, access control is the process of allowing a logged-in user access to a specific resource. There are many ways of doing this, but a flexible and standard method is to employ role-based access control lists. Zend Framework provides Zend_Acl to take care of this for us. There is a lot of jargon when talking about access control. These are the key terms resource something to be protected, such as a controller action or a data record privilege the type of access...

Services for cross module communication ApplicationDevelopment

Fri, 01 Apr 2011 05:29:35 GMT

When we are using multiple modules, it is very likely that we will need to share the functionality stored in the Models between each module. With Zend_Application, this is very easy as all we need do is instantiate the other module's Models. For example, if we are inside the Storefront module and want to access the Cms module's Models, then we can simply do When we instantiate the Model from within the Storefront module, the autoloader will automatically include the class for us. However, as...

Create the indexphp File ZendWebsites

Fri, 01 Apr 2011 03:05:49 GMT

As was noted in the .htaccess file, it's also the entry point for all incoming requests. In all, this file is responsible for completing four tasks setting PHP's include_path directive to include the Zend Framework's library directory, making it possible for Zend Framework's classes to be called within scripts without having to first include them using the require statement, referencing the boot-strap.php file, and finally jumpstarting Zend's front controller, which handles the request routing....

Adding Logging Capabilities Zend Web 2.0 Apps

Thu, 31 Mar 2011 09:08:58 GMT

The final thing we will look at in this chapter is adding logging capabilities to our application. To do this, we will use the Zend_Log component of the Zend Framework, which we will use in various places in our application. For example, we will record an entry in the log every time a failed login occurs in the members section. Although it is possible to do some pretty fancy things with logging such as writing entries to a database, or sending e-mails to a site administrator , all we will do...

Perlcompatible Regular Expressions ZendCertification

Wed, 30 Mar 2011 18:34:11 GMT

Perl Compatible Regular Expressions normally abbreviated as PCRE offer a very powerful string-matching and replacement mechanism that far surpasses anything we have examined so far. Regular expressions are often thought of as very complex and they can be at times. However, properly used they are relatively simple to understand and fairly easy to use. Given their complexity, of course, they are also much more computationally intensive than the simple search-and-replace functions we examined ear...

Creating the bootstrap resources ApplicationDevelopment

Tue, 29 Mar 2011 21:49:19 GMT

So far we have only created a basic skeleton for our Bootstrap class. Let's add the functionality to our three Bootstrap class resources now. The Locale resource configures the applications locale. This is always a good practice when creating an application as many Zend Framework components are locale aware. To set the locale, we simply create a new Zend_Locale instance and set it in the registry using the string Zend_Locale. This will then be accessible by all the locale aware components....

There are two functions we need to add to DatabaseObject_User to implement the password resetting. The first is called fetchPassword , which does the following 1. Generates a new password using Text_Password. 2. Writes the new password to the user profile. 3. Writes the current date and time to the user profile, so we can ensure the new password can only be confirmed within one day. 4. Generates a key that must be supplied by the user to confirm their new password. We also write this to the...

User Registration Login and Logout Zend Web 2.0 Apps

Fri, 25 Mar 2011 10:47:09 GMT

In Chapter 3 we looked closely at the user authentication and authorization aspects of the web application. We learned that authentication is when a user proves they are who they say they are, while authorization determines what that user is and isn't allowed to do. We created the necessary database tables to hold user details as well as the code to manage the database records. We then used the Zend_Auth and Zend_Acl components of the Zend Framework to control which areas of the web site users...

Tue, 22 Mar 2011 20:44:47 GMT

First we are going to handle any errors that may arise prior to dispatching the user request. In our application, before we dispatch the request, we load the configuration file, initialize the application logger, and connect to the database. Additionally, we are going to catch any errors that were not caught elsewhere that is, in the dispatch loop . Essentially what we are going to do is to wrap all of the code in the application bootstrap . htdocs index.php in a single try catch statement,...

Fat Model Skinny Controller ApplicationDevelopment

Mon, 07 Mar 2011 14:30:02 GMT

Along with our original question of where we should put our code, there are also many questions about whether code should reside in either the Controller layer or the Domain layer. This is where the concept of the Fat Model Skinny Controller comes in. The idea here is that we should try to push as much logic as possible into our Domain layer. By doing this, we hope to achieve the following goals Enhance separation of concerns

ZendControllerRouterRouteRegex ApplicationDevelopment

Mon, 21 Feb 2011 11:09:55 GMT

The routes we have looked at so far do a very good job of basic routing. However, they have their limitations. This is where the Router_Route_Regex comes in. This route gives us the full power of PHP's preg library, but this makes writing routes more complex. Even though they are a little more complex to use, I still use them for most of my routing as they are slightly faster than Router_Route. To start, let's convert our product example to use Router_Route_Regex route new...
