In some cases we might need to modify the autocomplete result in Drupal 8. For example, when editing a node, in content authoring section, there is an autocomplete textfield for entering the author for the content. By default, all users will be available in the autocomplete list, but there might be a case when we need to exclude the blocked user from the list. Fortunately, we are able to do that by using one hook function called hook_query_alter.
When we want to add newsletter feature to our Drupal website, we might end up finding the simplenews module as the solution. But, there is one problem that so many people asked about in the internet. By default, simplenews will send the whole node content in the body of the newsletter e-mail, not the teaser. Ideally, the newsletter e-mail will contain the teaser or trimmed version of the full content with the link to read it online to our website.
In Drupal 8 module development, we can easily create a table with pager. The code might be different from the one we use in Drupal 7, but it's still quite simple. I assume you have already learned to create a simple Drupal 8 "Hello World!" module as explained in there. So, let's start to create the table with pager. For example, we have a routing file, mydemo.routing.yml like the following.
Drupal 8 has reached the Alpha 4 version. It will be very interesting to see how it looks like before the stable version is released. To download this alpha version, you can navigate to https://drupal.org/node/3060/release then download the newest alpha version. Now we will see how this new version in action.
Updating Drupal core can be a difficult process because Drupal still doesn't support core update in online way. We must download the core first, extract it, then upload it to our server manually. This process can take more time because of so many manual operations. In order to solve that problem, I try to create a PHP script to make the update process easier. We just need to open a URL with some query string and then the script will download the requested Drupal core to our server. What we need to do next is run the update.php.
