Get next incremental ID

Version v2

Download

Instead of downloading the archive, you can download and apply this model as a recipe (Drupal 10.3 or later):

## Import recipe
composer require drupal-eca-recipe/eca_lib_0011

# Enable recipe with Drush (requires version 13 or later):
drush recipe ../recipes/eca_lib_0011

# Enable recipe without Drush:
cd web && php core/scripts/drupal recipe ../recipes/eca_lib_0011

# Rebuilding caches is optional, sometimes required:
drush cr

Purpose

This model increments a sidewide ID by 1 and returns that on screen. It uses Drupal's state service to store the value inbetween requests.
