Group Permissions Parameter

This module provides API to set group permissions on the group level using Group permissions module based on custom parameters (e.g. field in the group). Setting the permissions of a group is executed when saving it.

Features:

• Provides plugin base to set your mutable permissions (the permissions that depend on your parameters) while using the the permissions UI that comes with the group module to set the common permissions (the permissions that don't depend on parameters - fixed permissions).
• Provides a service for setting your mutable permissions using other way than creating GroupPermissionsParameter plugin instances. You identify the way yourself.
• To use GroupPermissionsParameter plugin for setting your mutable permissions, you could create a plugin instance per parameter or one plugin instance for multiple parameters
• Provides a form to sync the permissions on the group level with permissions from the group type level. This is useful in case new permissions should be granted to/revoked from existing groups. In your plugin, you can identify whether the mutable permissions should be applied on syncing or not. The form can be found under Groups menu.

Example:

<?php

declare(strict_types = 1);

namespace Drupal\custom_module\Plugin\GroupPermissionsParameter;

use Drupal\group\Entity\GroupInterface;
use Drupal\group_permissions_parameter\GroupPermissionsParameterBase;
