kevinquillen / RandomEntityFieldFormatter.php
Created June 25, 2018 19:04
This field formatter can be used on entity reference fields to select a random entity from the list to render. Note that the more items you have, the better the 'random' pick will seem. Also note that this will only fire once per cache write, then again on cache clear.
<?php
namespace Drupal\harlib_random_entity_display\Plugin\Field\FieldFormatter;
use Drupal\Core\Field\FieldItemListInterface;
use Drupal\Core\Field\Plugin\Field\FieldFormatter\EntityReferenceEntityFormatter;
/**
* Plugin implementation of the 'random_entity_field_formatter' formatter.

Another theme example - preprocessing fields on a paragraph. Formats links with SVG icons next to the title value. FormattableMarkup creates a markup for each link which is being passed as a new variable into the template. This could also be done via hook_preprocess_field, but demonstrates that you can do this from other preprocess hooks.
<?php
/**
* Implements hook_preprocess_paragraph().
*/
function mytheme_preprocess_paragraph(&$variables) {
$paragraph = $variables['elements']['#paragraph'];
$bundle = $paragraph->getType();
if ($bundle == 'fancy_links') {

Various ways of adding classes to anchors, as well as title markup within that anchor, from hook_preprocess_field in Drupal 8. These are all link fields, which do not have a base twig to modify the output of the a tag.
<?php
/**
* Implements hook_preprocess_field().
*/
function mytheme_preprocess_field(&$variables) {
if ($variables['element']['#entity_type'] == 'paragraph' && $variables['field_name'] == 'field_reference_link') {
foreach ($variables['items'] as $key => $item) {
$variables['items'][$key]['content']['#options']['attributes']['class'][] = 'hl__link-tag';
}

import "log"
func main() {
var url = "[redacted]/api/v1/room"

How to update a field storage length in hook_install (or hook_update). Note this does not cover more difficult things, like changing storage type altogether.
<?php
use Drupal\Core\Database\Database;
/**
* Implements hook_install().
*/
function mymodule_install() {
$connection = Database::getConnection('default');
