Basics of CakePhp. • Folder Structure. – App. • Config: all configuration files. • Models: application’s models, data sources and behaviors. • Controllers. I think there are really few blog posts out there with regards to beginner CakePHP tutorials. Most of them are also outdated. We will keep this. For this example, I’ll assume that your CakePHP application is This is an old trick, and if you’ve ever read a beginners’ tutorial to Ruby on.

According to a recent studyPHP is one of the most popular programming languages in the world.
In spite of this, PHP is often criticized for its inconsistent naming conventions, its lack of important features as compared to other languages like namespaces and its inherent disorganization. Furthermore, PHP is very easy to learn, and this has often led to the common misconception that most PHP developers are inexperienced and that their code is therefore prone geginner security vulnerabilities and exploits.
This is all true, to a certain extent. PHP itself offers virtually no real structure or organization, and thereby leaves coders free to express themselves in the most unpredictable and dangerous ways: These are obvious and common mistakes that can make PHP code completely unmaintainable.
Gradually, more and more PHP developers have gutorial this new philosophy and started developing frameworks, drawing their inspiration from other more-established languages in the pursuit of creating a structure for an inherently unstructured language. Many frameworks are available on the Internet, each with its own specific set of rules and conventions, achievements and failures.
Some degenerate into unusable and intricate collections of pre-built libraries and tools that enslave developers into complex and truly unusable programming methodologies; others do not. Ruby on Rails has definitely played a key role in inspiring the quest for the perfect web framework in programming languages other than Ruby.
These frameworks are often labeled Rails Clones. Ruby has features that no other programming language offers. At the same time, at least one person gave up on the idea of totally cloning Rails in PHP, but instead, decided to borrow its structure and basic concepts to make PHP more organized:.
I like the terseness of Ruby code, but I need the structure that Rails provides, how it makes me organize my code into something sustainable. For one thing, Cake is based on an MVC-like architecture that is both powerful and easy to grasp: Controllers contain the logic of your application. Each controller can offer different functionality; controllers retrieve and modify data by accessing database tables through models; and they register variables and objects, which can be used in views.
Cakepbp are active representations of database tables: It is important to note that in order to correctly apply the MVC architecture, there must be no interaction between models and views: Views can be described as template files that present their content to the user: Views should not contain complex business logic; only the elementary control structures necessary to perform particular operations, such as the iteration of collected data through a foreach construct, should be contained within a view.
This directory scheme must begiinner preserved, as it is essential if the framework itself is to work. Cake, like Rails, believes in the importance of convention over configuration: After downloading the CakePHP package, extract its contents to the document root directory of your web server, or one of its subdirectories. Confirming configuration of CakePHP. If you now try to access your application, the CakePHP default page will be displayed, warning you that a database connection could not be established.
Note how the table uses the plural notes. CakePHP is now configured properly, and we can turn tytorial the development of our application.
To create a scaffolded version of our memo application we need to create two begimner basic files: Create a file named note. You need only include the following lines in it:. You are now able to create, update, delete and display your notes with literally five lines of PHP code! The default edit view for a CakePHP application. If you paid attention to the previous example, you will notice that no view files were created. Furthermore, our controller had no actions, and that is also part of the scaffold magic.
In other words, all our URLs match a common pattern: The “t” in these thtml files indicates that these files are Cake templates. And what tutoriql delete. The first view we should create is a list of all the notes stored in the database, which will be the default page that displays when we access http: This file should contain the following code:.
Note that our template code is not a complete HTML document — things like the foor and header information for all files is also provided by the framework, and the default can of course be overridden later. This should display a list of all the stored notes, but if you try accessing http: The code for this action needs to be created in your controller.
It simply needs to retrieve all records from your notes database table and store bgeinner in an array. Cake achieves this task in one beginenr of code:. Assuming that your notes table has some records, the output of findAll will be something like this:. As I mentioned before, this output is accomplished with only one line of code. CakePHP dramatically reduces the befinner of repetitive and boring code required in your apps, thanks to its efficient built-in classes and intuitive conventions.
Creating our first view. We proceed similarly to view a single note. First, we need a view.

I used it in this view to create an input tag, a textarea and a submit button. At this point you should notice that something is wrong. In this case, if no data is submitted, the values from the record we want to edit are retrieved and displayed in the view. Otherwise, if data is submitted, the record is updated via the fot method as usual. Again, there are some obvious limitations to this simple function:.

After defining all of our CRUD operations, we can make the interface easier to use by adding some convenient links for adding, editing and deleting notes. We can also rewrite our index. It can take up to six parameters:. The customized index page. Not too difficult, is it?
One thing to keep in mind is that all those little conventions used in Cake actually matter: Yes, you can get around some of these conventions, but it is precisely these details that make Cake virtually self-configuring: At this point, you probably have a lot of questions. What does that mean? CakePHP offers a lot of features that cannot properly be described in a single article.
The examples in this article are inherently insecure.
Luckily, CakePHP comes with a Sanitize class, which can be used in Cake applications to filter strings or arrays to make them safe for display cakeph; insertion into the database. More information about sanitizing can be found in the CakePHP manual. After you define validation rules, all relevant actions and views should be modified accordingly. More information and examples are available in these pages of the manual.
Is there any way to turn off Cake’s ‘debugging mode’? Is there a main configuration file? Some of the settings that can be modified via this file include:.
All the business logic should go in my controllers, but what if I want to re-use something elsewhere? You will almost always have to create some complex logic for an application, and you usually want to re-use begginner of that logic. The most common way to include an application-wide function or variable so that it’s available in every controller is to define it in your AppController file. Even if you’re not planning to use an AppController at first, beginner often wise to create custom controllers which extend AppController rather than the Controller class.
An easy way to create custom classes handling a specific task is to create a component. CakePHP comes with some default components such as Session, which offers convenient ways to organize session data, or RequestHandler, which can be used to determine more information about HTTP requests. These are documented in the CakePHP manual:. Similar patches have been included in the core libraries to offer additional functionality in PHP4 as well. This is not just a convention: If someone tries to access it e.
CakePHP comes with some very handy helpers that can really make your life easier when it comes to creating views:. More information about helpers cakwphp available in the CakePHP manual. You can adapt your code and create a helper or a component to be used in conjunction with views or controllers. You can also try to integrate other software packages into Cake. By default, a NotesController will try to locate and load a Note model class.
In some cases, two or more tables might be closely related and would therefore be used with JOIN statements: More information betinner available in these manual pages. There is, however, a built-in Access Control List mechanism involving flat files or databases.
More information can be found in these manual pages. CakePHP Google user group beglnner a very lively user group; if you have a question to ask, go here. Documentation for offline use.
