Replacing drupal_get_path function with getTheme

Did you know that Drupal 8 introduced several changes and improvements to its architecture?

This has led to enhanced performance and flexibility.

Interestingly, certain functions have been deprecated to encourage better coding practices in Drupal 8. One such function is drupal_get_path(). It is no longer available in Drupal 8 or the later versions.

Today, we are going to explore how to replace drupal_get_path() with the getTheme() method to retrieve the path of a specific theme in Drupal 8 and so on.

More About the drupal_get_path() Function

The drupal_get_path() function was commonly used in previous versions of Drupal. It was used to fetch the path of a module or theme. Furthermore, it helped developers easily access the location of specific items in the Drupal environment.

However, in order to align with the improved architecture of Drupal 8, this function has been taken off the table.

How to Use the getTheme() Method

In order to access the path of a theme in Drupal 8 and later versions, we have to rely on the getTheme() method offered by the ThemeManagerInterface.

Today, we are going to take a look at an example to understand how to replace drupal_get_path() with this new approach:

Here, we import the ThemeManagerInterface class and then use the getActiveTheme() method. Then, we call the getPath() method on the theme object, which returns the path of the theme.
