Antonios Pavlakis: Having a go at creating a Behat 3 extension

In this post to his site Antonios Pavlakis "has a go" at creating an extension for the Behat (v3) testing tool. Behat is a testing tool written in PHP that helps with behavior-driven testing as opposed to unit testing with a tool like PHPUnit.

Ever since I got accepted to do a tutorial on Test legacy apps with Behat at the PHPNW15 conference, I’ve been meaning to look into creating custom extensions for Behat. I didn’t have enough time to research into this while preparing for the tutorial, so left it in my todo list in Trello.

During the PHPNW15 long weekend (Friday – Monday), at some point over lunch I was at the table where Matt Brunt (@themattbrunt) and Ciaran McNulty (@ciaranmcnulty) were having a conversation about this and Ciaran said (paraphrasing) “In order to be able to write an extension, you really need to understand how Behat works.”

So a few months later, sleeves up and I went into my vendor/bin/behat and started looking (and poking) around.

After looking in to two current extensions he started to get a feel for what was needed and the pieces that made up an extension. He then gets into detail on each of these pieces and shares some code/configuration he used to create the extension.

Binary Studio Blog: Definitive Guide On Creating Custom Providers For Laravel OAuth2 Authorization

A new guide has been posted showing you how to create custom OAuth2 providers for your Laravel application. In this case they wanted to hook the application in via Socialite to the VK social network but needed a custom connector to make it happen.

First of all let’s say that social authorization is very popular and frankly speaking it’s really handy tool. Surfing internet we can see a lot of sites and services which offer login with Facebook, Twitter, Google and other social networks. […] If you’re building your website in PHP using Laravel, probably you’ve noticed Socialite which provides OAuth / OAuth 2 authentication with Facebook, Twitter, Google, and GitHub. The most famous social network which provides OAuth2 authentication in Russian segment of the internet is vk. But there is a lack of such connector (provider) in Socialite library. Actually it’s not a hard problem, so let’s build new VkProvider on top of Socialite’s components.

He starts with a brief look at the typical OAuth2 authentication flow between the social network and your application. From there it gets more vk.com specific. He shows how to set up the custom application on their side, updating your configuration with the credentials and installing Socialite. He then implements a „VkProvider“ defining the required methods based on the interface. He then registers it as a „SocialiteServiceProvider“ and uses it in a „login“ request route.

Phillip Shipley: Creating a PHP Nexmo API Client using Guzzle Web Service Client – Part 2

Phillip Shipley has posted the second part of his series (first part is here) about creating a PHP client for the Nexmo API with Guzzle, the popular PHP HTTP client.

In Part 1 of this series we laid a foundation for consuming the Nexmo SMS API and covered a few ways to interact with it. In this part we’ll create the actual Guzzle Web Service Client to interact with it to demonstrate how simple it can be.

He starts by getting Guzzle installed via Composer including a few extra components: guzzle-services, retry-subscriber and log-subscriber. He defines the structure (code) for the message to send to the Nexmo service. Next up is the creation of the actual client that takes in configuration settings and extracts the HTTP location and applies the provided credentials to the connection. Finally he makes a simple SMS client that extends this base client and puts it to use with a simple message defined in an array (to, from and text contents). The client then reports back the results in a simple nested array with response information from the Nexmo API.

SitePoint PHP Blog: Creating Custom Field Formatters in Drupal 8

The SitePoint PHP blog has a new tutorial posted today showing how to create custom field formatters in a Drupal 8 application. Custom formatters allow you to enhance the current functionality of objects in the application and extend them with additional functionality.

With the introduction of annotated plugins, a lot has changed in Drupal 8. We have a more streamlined approach to describing and discovering pieces of functionality that extend the core. Along with many other components, the former Field API (part of the larger and consolidated Entity API) is now based on plugins. In this tutorial we will go through defining a custom field formatter for an existing field (image). What we want to achieve is to make it possible to display an image with a small caption below it. This caption will be the title value assigned to the image if one exists.

They start with a new custom module, starting with just the YAML configuration. Then they help you create the field formatter as a plugin in the „Plugin/Field/FieldFormatter“ namespace (code included). They explain how this code works and show how to add it as a hook to make it available to the template layer. Finally they show it in use and how it places the title value into the image caption in the result.
