A Drupal module extending [drupal/entity\_reference\_tree](https://www.drupal.org/project/entity_reference_tree) to provide a hierarchy of entities configured through disambiguation points in the pathbuilder, e.g., tags or other forms of taxonomy. This module depends on `drupal/entity_reference_tree` and was tested successfully with `2.1.0`.

**Note:** This module depends on the dynamic dispatch to other tree-builders defined in `src/web/modules/contrib/entity_reference_tree/src/Controller/EntityReferenceTreeController.php:104`. Should this dispatch ever go away, this module **will break** (or at least cease to function, which is the same).

Required dynamic dispatch in `drupal/entity_reference_tree`:

```
// Instance a entity tree builder for this entity type if it exists.
if (\Drupal::hasService('entity_reference_' . $entity_type . '_tree_builder')) {
  $treeBuilder = \Drupal::service('entity_reference_' . $entity_type . '_tree_builder');
}
```

### Local development environment

[](#local-development-environment)

For local development, it is **highly recommended** to install this module into an existing Drupal codebase, e.g., under `web/modules/custom`. Furthermore, we recommend at least a basic WissKI installation (c.f. [`drupal/wisski`](https://www.drupal.org/project/wisski)). This will provide a richer code-completion for base-Drupal, as well as WissKI-specific code.

**Important:** without a local Drupal installation, static analysis via `phpstan` will fail miserably, as it relies on a Drupal autoloader.

The following example assumes an installation, and clones into `web/modules/custom`:

```
$ cd /web/modules/custom
$ git clone https://github.com/dmwg/wisski_entity_reference_tree
$ cd wisski_entity_reference
$ composer install
```

### Linting & Static analysis

[](#linting--static-analysis)

Please run `vendor/bin/phpcs --standard=Drupal` and fix any flagged errors; `vendor/bin/phpcbf --standard=Drupal src` can assist.

Please run `vendor/bin/phpstan` and fix any errors; don't let a failing build discourage you, we'll try and figure it out in the PR.
