How to Develop a Custom Drupal Module

Modifying existing code might be all fun and games for a developer, but what about the time when you have to venture out to unknown shores and create your own custom modules? It has been granting its users with benefits like code reuse and encapsulation, and these benefits allow users to maintain and structure code in a better way possible.

However, this might leave you with a farrago of questions - What do I need to know in Drupal 8 to start developing? What is OOP? Why is it used in Drupal 8 to make modules? How does it create the custom modules? We all know that Object Oriented Programming has provided us with the power to create our desired objects and construct methods to handle them.

And with the usage of various OOP principles and design patterns, Drupal 8 has brought about a much easier path in terms of development. Drupal 8 serves as a great introduction to PHP.

Here are some of the design patterns which are important to understand to solve the basic object-oriented design problem.

Therefore, PHP namespace allows you to dodge this issue by presenting a similar code into neat little packages, or even to determine ownership.

Drupal 8 consists of a number of files that declare the namespace in order to remain compatible with PHP 5. Therefore, with the help of two standards in Drupal, PHP interfaces and traits are easily namespaced. For example. And, for the file which does not declare a namespace has to specify with the use statement at the top of the file For the classes that are without backslash, they must be fully qualified when used in the namespace file.

PHP has allowed the classes to be aliased when they are being imported into a namespace. It is done to avoid the collision. But suppose the collision still happens, you can alias the classes by prefixing the next higher portion of the namespace. Dependency Injections is that software design pattern that would allow you to remove hard-coded dependencies and also make it possible to change them either on runtime or at compile time.

Drupal 8 introduced the concept of services object managed by service container in order to decouple reusable functionalities. It creates the services pluggable and replaceable by registering them with the help of a service container. These services are used to perform operations that include accessing of the database or sending up of an e-mail. Therefore, to let the code simply access the database without worrying about whether the database is MySQL or SQLite , usage of core provided service via the service container is done.

These core services are defined in CoreServiceProvider. Somewhat like:. Each service depends on the other service. Like in the example above path. Dependency injection is the preferred procedure for accessing and using services in Drupal 8. Services are transferred as an argument to the container or injected via setter methods.

Much of the code that Drupal 8 uses to handle routing, sessions, and service container. These components are flexible and universal solutions. Annotations are the comments in your code that contain meta information. The main advantage of annotations is that they improve performance due to the less memory usage and is placed in the same files as the class is. These are the read using Doctrine annotation parser offers to implement custom annotation functionality for PHP classes.

Plugins are considered as a small piece of functionalities that can be swapped. Drupal consists of different plugins with different types. The CMS platform provides a set of guidelines and reusable code components that allows the developer to expose pluggable components within their code and manage these components with the user interface.

Plugins have three basic elements namely. Plugin type: It is a central controlling class that would define how the plugin of this type will be discovered and instantiated. Plugin Discovery: It is the process of finding plugins within the code base that is qualified for the usage. Plugin Factory: It is responsible for instantiating specific plugins. If the end user is aware of key OOP principle and design pattern , then it becomes even more easy for them to use it with Drupal.

For instance, different services become available when default container initializes while bootstrapping Drupal. In short, you have the power to build your own class, then define it as a service and make it available in the container.

Drupal 8 has a set of coding standards just for object-oriented code and adheres to common PHP coding conventions. For an empty space between property definition and method definition:.

And then for the space between the end of method and end of the class definition:. In cases that have a fluid interface of the classes, and code span of more than one line, the method calls should attend 2 spaces.

Though in Drupal 8 heavy use of Symphony 2 components handle the routing part. Drupal 8 also uses YAML format.

The routing system is responsible for matching paths to the controller and then you are allowed to those relations in routes. The additional information can also be passed to controllers in the router. Each route has to be described separately from one another with the involvement of these characteristics :. Under path, we specify the path where route should be registered. This acts as the URL to route. It is important to build the ModuleController. You just have to create a folder along with a file name with the following content.

A controller is a type of PHP function that you create. In the case of items and route example,. So here it is. Now, you know the concepts of OOP to create a custom module. Yes, it is important to know OOP, design patterns, Twig, and modern PHP trends for creating the modules, and Drupal makes this task even more easy for you.

Whether it is the development of a new custom module or optimization of your new website, everything is handled and tailored according to your needs.

Share your piece with us at [email protected]. We also welcome ideas in the planning phase.

Have a question? Email us at [email protected]. Scary, right? Start With Prerequisites to Create Custom Modules We all know that Object Oriented Programming has provided us with the power to create our desired objects and construct methods to handle them. PHP Namespace introduced in version 5. Aliasing the class PHP has allowed the classes to be aliased when they are being imported into a namespace. Somewhat like Plugins Plugins are considered as a small piece of functionalities that can be swapped.

It is important that there should always be one interface or trait per file. It should also be noted that it is only possible to define a class in a module if the class does not contain any superclass. Next in this coding standards would be whitespace or indentation method. Both of them leave an empty line between the start of the class definition and property definition. For an empty space between property definition and method definition These naming conventions set of rules would help you to choose the character sequence to be used for the identifier that denotes the variables, functions, types and other entities.

There might be chances where you would also wish to extend your code. Thus the use of separate interface definition would help you by contributing highly in terms of flexibility and would also neatly centralizes the document, making it easier to read. A class that has to be extended must always provide an interface that other class can implement rather than forming them to extend the base class.

Also, it is important for all the methods and properties of classes to specify the visibility private, protected or public. The use of public properties is strongly discouraged. It allows the entry of unwanted side effects and exposes implementation specific details, which in turn makes swapping out of class for another implementation much more hard.

It is basically used to specify the expected data type of an argument in a function declaration. Although type hinting is optional, it is recommended for debugging. If an object of the incorrect type is passed, an error is shown. This would guarantee that you are checking for a type and also maintaining a fluid code.

Next is instantiation. Drupal coding standards look down upon directly creating classes. Rather it is better to create a function to instantiate the object and return it. It is because: The function which is written can be reused to return different objects with the same interface as it is needed. You are not allowed to chain construct in PHP, but you are allowed to chain return object from the function.

Last but not the least - Chaining. Chaining is that blessing for you which allows you to immediately call a function on a return object. Become our reader!

We will be looking at creating blocks by using custom blocks like in the first part of this series, but this time we will look at creating a custom block type to use as a custom block, and then look at creating blocks with views, and last but not least menus. We won't cover more advanced topics of exposing modules as blocks but at some stage in the future, I may look at converting a Drupal 7 custom module code to Drupal 9. When using and creating blocks, the first question to ask is what do you want to use the block for? The following is a list of some possibilities, it's not an absolute list but it gives us something to look at. Now you know what you want to create you need to decide the best way to create what you want. I am going to make a suggestion based on the possibilities discussed in the overview and not resort to custom code or the need to use contributed modules i. These are only suggestions and you may have reasons to choose a different method and that is fine. Also, remember you may want to get something up fast and then look for a better way of achieving the same result.

Creating a Custom Filter in Drupal 8

They are an integral part of Drupal and the way it displays information. While Drupal has a variety of useful blocks out of the box for most scenarios, there might be times when custom blocks are required. This method is pretty straightforward and easier than creating a block programmatically. However, it also is less flexible and customizable than programmatically creating a block. This method requires a little more understanding of the way Drupal works, however, once you get the hang of it, it gets pretty easy.

Drupal 101: Creating custom content with Panels

If your site uses multiple roles so that your content editors do not have full administrator privileges, then the easy way may be all you need:. If you haven't added any tools to restrict this, then you're all set. If the service you want to embed from also requires you to include a snippet of JavaScript, then you'll need to enable that for your new text format as well. You'll then want to restrict this format to site administrators which should hopefully be a separate role from that of your site's day-to-date content creators and editors. You can then add blocks where needed and use this new text format so that you can add your embed code to the block. It is very unsafe and can't even be turned on in Drupal 7 unless you upgraded to Drupal 7 from an earlier version that had it turned on. In addition, the module has been completely removed from Drupal 8.

The views module is well-loved for its ability to let you define a custom set of content on your site, and through the use of exposed filters, allow the site.
