Drupal 8 Tricks

I found this today while searching the web exactly for how to do that, but the answer wasn't very easy to find.

Reproducing here in case the site goes offline.

As this code is from 2018, it should work with Drupal 8, maybe Drupal 8.9, and hopefully with Drupal 9 and 10. I will test when I have time.

Bootstrap Drupal 8 from external script

Found this today while searching for "Drupal stuff"

Reproducing it here so it doesn't get lost.

situation: building a subtheme of a subtheme, and need to override a library that was already overridden in the first subtheme.

there is a bug in library overrides, see https://www.drupal.org/project/drupal/issues/2642122

the answer is in reply #18 of that issue thread (thank you Jacine)

Downloading and installing libraries for every new site is a PITA.

So I've spent an hour today with trial and error to find out how libraries can be installed with composer.

Results: there are three things to do in composer.json

Drupal core uses the same TWIG template for all instances of a menu. bummer.

Luckily, KristianKaa added this neat piece of code:

/**
 * Implements hook_preprocess_block().
 */
function mymodule_preprocess_block(&$variables) {
  $variables['content']['#attributes']['block'] =    $variables['attributes']['id'];
}

I'm fine-tuning a theme using Lighthouse and one error that kept coming back was 

"Ensure text remains visible during webfont load"
and then
"Specify `@font-display` when defining custom fonts in your theme"

if using local fonts, this is easy, just add font-display:swap to your css.

if using font libraries, this is different. For Google fonts, it can be easily achieved by adding "&display:swap" at the end of the URI in the theme's libraries.yml file

the easiest solution to this problem is to login to your database and purge the "flood" table.

I had been pulling my hair out on this one for a couple of hours, as usual with Drupal.

Within a TWIG template, I wanted to check the current URL for the presence of a certain string and include a webform if the string was found.

Now this is easy to do using the native block system or also in the Context module, but that particular template was displaying programmed elements, and my webform had to go between them.

the first thing of course is to use the TWIG tweak module (I consider this essential in any Drupal site).

To reset the admin password without access to admin email and without using drush, you first need to choose your new password, then generate a hash for it.

Then use phpMyAdmin to access the Drupal database and in the Users table replace the hash, then delete the cached password.

this is a stub, the article will be about the quick and dirty method of updating Drupal, no composer, no drush required.

do a full backup of website and database first!

easy steps on a Plesk server, but you can easily reproduce on another platform:
