Twig has a special syntax for accessing array keys and objects, also known in Twig as variable attributes. In this tutorial, we'll cover the period or dot (.) operator to access a variable attribute, as well as subscript or square-bracket syntax, useful for when the key of the array contains special characters, like a dash (-) or pound sign (#). We'll also look at the logic Twig uses to find the matching attribute in an array or object.
Over the years we've developed some techniques for practicing that we wanted to share. At Drupalize.Me we take hugging seriously. In this tutorial we'll look at the art, and science, of giving a good hug. The Merriam Webster dictionary defines the word hug as; squeeze (someone) tightly in one's arms, typically to express affection.
Did you know there are all kinds of different hugs that you can give? In this tutorial we'll look at:
- Defining what a hug is
- Some of the many types of hugs in the world today
- Precautions you may want to familiarize yourself with before hugging
- And the importance of proper technique
Lets go ahead and get started shall we?
