A blog about web development and Drupal.
It has been a few months since Drupal 8 was released and sites built with it are starting to crop up. I myself have had the pleasure of working with it, and more Drupal 8 projects are certainly on the horizon. From a developer's perspective, this version is substantially different from the previous one, and we will need to learn a handful of new ways of doing things. To ease the process, I have put together this list of how-tos with tasks that I commonly encounter during development. I hope you will find it helpful.

In Drupal 7, hook\page\alter was a convenient way to go when we needed to modify page elements that were added by other modules. Drupal 8 does away with this hook - hopefully for the better. To fill the void created by hook\page\alter’s dismissal, the following hooks have been introduced. - hook\page\attachments() - hook\page\attachments\alter() - hook\page\top() - hook\page\bottom() - hook\theme\suggestions\HOOK() - hook\theme\suggestions\HOOK\alter() In addition, we can still implement hook\preprocess\page, which does let us override or add content to the page.

This works just like a form callback; we can add our fields to the $form array…
Drupal 8 is just around the corner, and it has reached an important milestone: beta-to-beta updates will be provided for each beta release going forward. That gives me some confidence that no major re-works are to be expected if I start building with Drupal 8. That said, we are still facing a sizable documentation gap regarding the changes in the API. My first encounter with this problem was when I was building a custom style plugin for Views. This post discusses how this is done in the new version of everyone's favorite CMS. In Drupal 7, we had hook\views\plugins(), which let us register new…
