Preprocess functions allow you change existing variables, or add new variables, for a template file using PHP code. In this final exercise for the course, you'll define a PHP function that implements a preprocess hook and define a new variable using PHP and make it available for use within a specific template file. Specifically we want to create a new variable named {{ today }}
that contains the current date and gets passed to the page.html.twig template file. You should work on the exercise steps below first, and you can refer to the video if you need some help.
If you want to try and accomplish this on your own first you'll need to:
Learning objectives:
- Create a THEMENAME.theme file.
- Write a proprocess PHP function that adds variables to a page template file.
Note: At the end of this exercise, you'll find a video walk-through of the solution.
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?
