Many of the variables that you have access to inside of a Twig template file are arrays. For example a list of values for a multi-value field, or a set of error messages generated when validating a form submission. In order to work with arrays in Twig you'll need to understand how for loops work. This is essential information for anyone creating Drupal themes.

In this tutorial we'll cover:

  • Using the for tag to iterate over an array
  • Using the loop variable inside of a for loop for additional context
  • Various alternative syntaxes for looping over variables in Twig templates
