Working with Entities in Drupal 7
May 05, 2016 @ 12:29:26

On the Ibuildings site there's a tutorial posted talking about working with entities in Drupal 7 and how creating your own classes for them can make them easier to manage.

Developers love object-oriented code. But how can this be achieved with Drupal 7 entities? By default Drupal uses a single class for all entities of a given type. For example, all node objects are standard classes (stdClass) and all entity objects have the Entity type. I personally like to have an entity model that only exposes the functionality that is applicable for the logic of your domain.

[...] Wouldn’t it be nice to create your own classes for entities?

First off, he starts with a refresher on what entities are and how they relate to the database schema. He points out the difficulties in using them and testing their types. He then provides his suggested solution for "all" of your entity problems - the creation of classes for the different entity types. He gives an example using an Article type and how to create/use them in your Drupal code.

Mark Ragazzo:
Immutable objects
May 04, 2016 @ 13:55:42

In a post to his site Mark Ragazzo looks at immutable objects - what they are and how they can be used in a PHP application with some "final" functionality.

In this short article we will see what immutable objects are and why we should consider to use them. Immutable object is an object that does not change its state after it was created. Immutable objects usually are very simple. You may already seen them as enum types or primitives like DateTimeImmutable.

Further in this article you will learn that making simple objects immutable may save significant amount of your time by making impossible to make certain types of mistakes.

He starts with a list of a few things to remember when implementing immutable objects (like using the "final" keyword) and problems that can come without them. He then gets into some examples, showing how to create immutable Address and Money objects and how to use them when you need to update/get values from the object. He also covers some common "accidental mutability" cases like leaking internal object references and inheritance problems.

Building a SparkPost Client: TDD with PhpUnit and Mockery
May 04, 2016 @ 12:26:32

On the SitePoint PHP blog they've continued their series covering the SparkPost mail delivery service and integrating it in to your application. In this latest part of the series author Christopher Pitt starts looking at the SparkPost API and uses it as a chance to practice some TDD (Test Driven Development) skills.

In a previous post, we looked at SparkPost (as an alternative to Mandrill), and explored a bit of the official PHP client. The official client handles a decent amount of work, but I got to thinking about what it would take to build a new client.

The more I thought about it, the more it made sense. I could learn about the SparkPost API, and practice Test Driven Development at the same time. So, in this post we’ll look to do just that!

He uses a few different libraries to explore the API and its endpoints: Guzzle for the HTTP requests and the Mockery+PHPUnit combination for the testing. He includes the setup and configuration for the testing environment and some sample tests for making sure things are connected. He then integrates Mockery into the testing, using it to mock the Guzzle requests and still have the tests pass even without the actual connection. He then works through several other tests and finishes the post with a mention of building coverage results for the "Client" class.

Starting a Business with Laravel Spark
May 02, 2016 @ 11:51:22

On the SitePoint PHP blog there's a new tutorial from Christopher Pitt showing you how to "start a business" with Laravel Spark, the recently released scaffolding product that takes care of a lot of the typical "business" handling for online products.

I am really excited about Laravel Spark. By the time you read this, there will probably be a multitude of posts explaining how you can set it up. That’s not as interesting to me as the journey I’m about to take in creating an actual business with Spark!

The idea is simple. I have created a Pagekit module which you can use to back up and restore site data. The module makes it easy to store and download these backups, and restore them on different servers.

He starts off with some of the background behind the product and getting Spark set up with some additional functionality (like additional user fields and gathering billing information). He then creates the functionality allowing for the actual storing of the backups and API functionality that integrates with it. The post wraps up with his look at adding the code needed to download the backups and return them back to the user.

Kick-Start WordPress Development With Twig: Timber Image, Menu, and User
May 02, 2016 @ 10:51:47

The TutsPlus.com site has posted the next part of their series looking at integrating WordPress and Twig with a look at showing images, menus and users in your WordPress UI.

By now you have read about the basic concepts of using Twig through Timber, while building a modular WordPress theme. We've also studied block nesting and multiple inheritance with Twig, based on the DRY principle. Today, we are going to explore how to display attachment images, WordPress menus, and users in a theme with Twig through the Timber plugin.

They go through each of the topics (images, menus and users) and provide the code needed to both gather the data needed and the templates to render the views. This all makes heavy use of the Timber functionality to integrate it with the overall WordPress structure. Screenshots are also included of the resulting output to help you ensure things are working as expected.

How to Authenticate Users With Twitter OAuth 2.0
Apr 29, 2016 @ 11:21:10

On the TutsPlus.com site they've posted a tutorial showing you how to integrate with Twitter's OAuth authentication through a few simple steps allowing the well known "Log in with Twitter" functionality.

In this tutorial, you will learn how to use Twitter API 1.1 and OAuth 2.0 to authenticate users of your application and publish a test tweet.

To create services which act on behalf of users' accounts and make it really secure and easy to develop, we need three things: a Twitter application, the REST API and access to the user account To put the pieces together into a working mechanism, we need an authentication framework. As a Twitter standard, the REST API identifies Twitter applications and users using OAuth.

The tutorial starts with a brief description of OAuth for those that aren't overly familiar with the use of the technology and its flow. They then go through the steps you'll need to get your app working with Twitter's OAuth handling:

  • Create the Twitter application
  • Get the OAuth credentials (secret and key)
  • Installing a Twitter library via Composer
  • Configuring your app with the OAuth credentials
  • Building out the code to send the request to Twitter and receive the resulting callback

Once you receive that callback you'll have a token you can use to uniquely identify the user and interact with the Twitter API on their behalf. The post ends with some related links to other resources with more details about the Twitter API, their OAuth handling and other Twitter libraries.

How To Process Tweets in Real-Time with Laravel
Apr 29, 2016 @ 09:10:16

The Scotch.io site has a tutorial posted showing you how to combine Laravel and the Twitter Streaming API to process tweets in real time inside your application.

This tutorial will show how to use the Twitter Streaming APIs to process tweets in real-time from a Laravel application. There are a variety of use cases for this: perhaps you want to auto-respond to mentions of your company, run a contest via Twitter, or create support tickets when users complain about your product. For this tutorial, we'll build a "featured tweets" widget to display approved tweets on our app's home page.

He starts with an overview of the tools and terms you'll need to know about for the tutorial and a few notes of things to watch out for. He then describes the overall structure of the application (an app just to show the tweets) and links to a repository for the impatient. He then breaks up the rest of the tutorial into several steps:

  • Creating a new Laravel application and installing the Phirehose library
  • Building a "process tweet" job and matching TwitterStream class to use Phirehose and dispatch the job
  • Make the artisan command to connect to the API and the application you created
  • Configure your queue driver and run the processing command
  • Set up a "Tweet" model to connect the application and database table

He finishes the post showing how to make the ProcessTweet Job useful, set up some basic authentication and pass the currently processed tweets into the default "Welcome" view.

Rob Allen:
DI Factories for Slim controllers
Apr 28, 2016 @ 10:38:10

In a recent post to his site Rob Allen shows you how to create dependency injection factories for Slim (v3) controllers.

When using classes for route actions in Slim 3, I recommend using a single class for each route. However you can use a single class for multiple routes. To register a class method to a route you pass a string as the route callable where the class name is separate from method by a colon. Slim will retrieve MyController from the DI container and then call the listAction method using the usual signature. f you don't specify a method, then Slim will see if it treat the class as a callable, so you can implement __invoke() and then register the route.

He shows how to create a factory method as a part of the Slim container for a constructor and inject the correct dependencies. He shows how to register these dependencies as other factory methods inside the DI container and how to pull them back out for injection. He prefers this method as it reduces "hidden dependency" issues and makes the controllers themselves easier to test.

Matt Stauffer:
Using SparkPost for Transactional emails with Laravel
Apr 27, 2016 @ 10:54:42

Matt Stauffer has a post to his site for the Laravel users out there wanting to seed "transactional emails" from their applications. In this tutorial he shows you how to use the SparkPost service to send emails with very little effort.

Recently, Mandrill announced that they'd be sunsetting their transactional email service and instead rolling it in to a secondary service for paid MailChimp users. That's fine for them, but many of us were using it for small one-off apps and weren't interested in all of a sudden paying money to send 100 emails a month.

[...] But right when Mandrill announced their pricing change, a new transactional email provider came out of nowhere: SparkPost. [...] So let's walk through the process of signing up and moving Giscus, my app for notifying you of comments on your gists, from Mandrill to SparkPost.

First he walks you through the process of getting a SparkPost account set up and configured to receive messages from your application. He then moves over to the Laravel side, upgrades his installed version and configures it with the "secret" value SparkPost provides and changes the MAIL_DRIVER value - that's basically it.. He also includes some screenshots of other parts of the SparkPost admin interface to show some of the other functionality included.
