# Organic Groups : Site Manager

This module provides support to setup a platform supporting multiple (sub)sites
based on [Organic Groups][link-og] (OG) functionality.

* Define what node types should be used as Site's.
* Simplified OG API by providing OG function wrappers.

> *NOTE* : Site entities are limited to node entities.

## Functionality

This module and its submodules adds functionality to support:

### Included in og_sm module

* Support for Group types to become sites enabled (Site).
* Support for Group Content types (Site Content).
* Support for Group Users (Site Users).
* Yml file discovery for site links.

### Included in og_sm_admin_menu module

* Site administration menu that replaces the default admin toolbar when the user
is in a Site context.

### Included in og_sm_config module

* Allow site specific configuration.
* Allow overriding global config per site.

### Included in og_sm_content module

* Site content administration

### Included in og_sm_context module

OG context detection based on:

* Path alias of the current page.
* Paths starting with group/node/NID

### Included in og_sm_menu module

* Centralised functionality to provide Site specific menu items.

### Included in og_sm_path module

* Define a Site path prefix per Site.
* Automatic path aliasing with the Site path as staring point.
* Auto update of Site content aliases and Site related page aliases when the
Site path changes.
* Altering the `group/node/nid/admin/...` paths to `[site-path]/admin/...`.

### Included in og_sm_routing module

* This module adds support to have Site specific routes.

### Included in og_sm_taxonomy module

* Support global vocabularies with Site specific terms.
* Manage terms per Site.
* Select only from terms within the Site when creating content.

## Requirements

Minimal system:

* PHP 7.3 or higher.
* Drupal 9.1.x or higher.

The Sites functionality is built upon [Organic Groups][link-og].
Following modules are required to use the Sites functionality:

* [Organic Groups][link-og]

## Installation

Enable the Organic Groups Site Manager module.

Edit the node type settings of the types that should be Site types.

Enable:

* The Organic Groups > Group checkbox
* And the Site Manager > Site Type checkbox.

## API

> *NOTE* : In the following examples the og_sm services are accessed directly
> for sake of simplicity, however it is recommended to access these using
> [dependency injection][link-dependency-injection] whenever possible.

### Load a Site node

Get a Site node by its Node ID (nid). Will only return the node object if the
node exists and it is a Site node type.

```php
$siteManager = \Drupal::service('og_sm.site_manager');
$site = $siteManager->load($site_nid);
```

### Currently active Site

A lot of code depends if we are currently in an active Site context.

A helper method is available to get the currently active Site node.
This is a wrapper around the `OgContext::getGroup()` method + loading the node.

Get the currently active Site node:

```php
$siteManager = \Drupal::service('og_sm.site_manager');
$site = $siteManager->currentSite();
```

### Clear all cache for Site

Clear all cache for one site.

This method does not clear the cache itself, it triggers the
`SiteEvents::CACHE_CLEAR` event so modules can clear their
specific cached Site parts

```php
$siteManager = \Drupal::service('og_sm.site_manager');
$site = $siteManager->clearSiteCache($site);
```

### Site types

Get a list of node types that are Site node types:

```php
$siteTypeManager = \Drupal::service('og_sm.site_type_manager');
$site_types = $siteTypeManager->getSiteTypes();
```

### Check if node is a Site

The module provides helper methods to detect is a node or node type is a Site
node type:

Check if the given node is a Site type:

```php
$siteManager = \Drupal::service('og_sm.site_manager');
$isSite = $siteManager->isSite($node);
```

### Check if a node type is a Site type

Check if the given node type is a Site type:

```php
$siteTypeManager = \Drupal::service('og_sm.site_type_manager');
$isSiteType = $siteTypeManager->isSiteType($type);
```

### Get the path to the Site homepage

Get the url to the homepage of a Site. This will return by default the path to
the detail page of the Site. Modules can implement
`hook_og_sm_site_homepage_alter()` to alter the path.

The function will return the url instance based on the given Site or, if no Site
is provided, the current Site (from OG context) will be used.

```php
$siteManager = \Drupal::service('og_sm.site_manager');
$homepageUrl = $siteManager->getSiteHomePage($type);
```

### Site content types

Helper method to get a list of site type objects that can be used to create
content within a site.

```php
$siteTypeManager = \Drupal::service('og_sm.site_type_manager');
$siteContentTypes = $siteTypeManager->getContentTypes();
```

### Check if a content type can be used within a Site

Helper method to check if a given content type can be used to create content
within a Site.

```php
$siteTypeManager = \Drupal::service('og_sm.site_type_manager');
$isSiteContentType = $siteTypeManager->isSiteContentType($type);
```

### Check if content belongs to a Site

Helper methods to get the Site (if any) of a given content item (node) belongs
to.

Get all the Site nodes a content entity belongs to.

```php
$siteManager = \Drupal::service('og_sm.site_manager');
$sites = $siteManager->getSitesFromEntity($entity);
```

Get the Site node object from a given site content entity object.
If a entity belongs to multiple Sites only the first Site will be returned.

```php
$siteManager = \Drupal::service('og_sm.site_manager');
$site = $siteManager->getSiteFromEntity($entitiy);
```

Check if the given entity belongs to a Site:

```php
$siteManager = \Drupal::service('og_sm.site_manager');
$isSiteContent = $siteManager->isSiteContent($entitiy);
```

Check if the given entity belongs to a given Site:

```php
$siteManager = \Drupal::service('og_sm.site_manager');
$isMember = $siteManager->contentBelongsToSite($entitiy, $site);
```

### Check if user is member of a Site

Helper methods about the Sites a user is member of.

Get the Site nodes a given user belongs to:

```php
$siteManager = \Drupal::service('og_sm.site_manager');
$sites = $siteManager->getUserSites($account);
```

Check if a user is member of the given site:

```php
$siteManager = \Drupal::service('og_sm.site_manager');
$isMember = $siteManager->userIsMemberOfSite($account, $site);
```

### module_name.site_links.menu.yml

The naming of the .yml file should be `module_name.site_links.menu.yml`

The allowed parameters per menu item are the same as core's `module_name.links.menu.yml`
file. Dynamic route parameters like the group's entity type (`{entity_type_id}`)
and the site node (`{node}`) are automatically injected when needed.

Example:

```yml
og_sm.site.admin:
title: 'Administer site'
route_name: entity.node.og_admin_routes
menu_name: og_sm_admin_menu
og_sm.site.structure:
title: 'Structure'
route_name: og_sm.site.structure
parent: og_sm.site.admin
menu_name: og_sm_admin_menu
weight: 30
options:
attributes:
class:
- 'toolbar-icon-system-admin-structure'
```

### hook_og_sm_site_menu_links_discovered_alter(&$items)

Alter the menu items as gathered using `module_name.site_links.menu.yml`.

## Events

The og_sm module triggers multiple events to make it easier to alter
functionality when a Site is involved.

### Clear all Site cache

When `SiteManager::clearSiteCache()` is called, it will not clear any cache
itself. It will trigger the `SiteEvents::CACHE_CLEAR` event
so modules can clear the Site parts they have cached.

* `SiteEvents::CACHE_CLEAR` : Cache clear method is called for the given Site.

### Site node type action events

The module triggers events when a node type is being added or removed as being a
Site node type.

* `SiteTypeEvents::ADD` : Site node type is being added as a Site type.
* `SiteTypeEvents::REMOVE` : Site node type is no longer a Site type.

### Site action events

The module watches actions taken place on Site nodes and triggers its own events
when an action happens:

* `SiteEvents::PRESAVE` : Site node being prepared to be inserted or
updated in the database.
* `SiteEvents::INSERT` : Site node being inserted.
* `SiteEvents::UPDATE` : Site node being updated.
* `SiteEvents::SAVE` : Act on a Site node being saved. Will be
triggered after a node is inserted or updated. It will always be called after
all the `SiteEvents::INSERT`/`SiteEvents::UPDATE` events listeners are processed.
* `SiteEvents::DELETE` : Site node being deleted.

There are also special post-action events available: the default action hooks
(insert, update, save and delete) are called during a DB transaction. This means
that it is not possible to perform actions based data in the database as all SQL
operations are not committed yet.

To allow modules to interact with a Site node actions after the Site node & all
queries by implemented events are stored in the database, following extra action
events are triggered:

* `SiteEvents::POST_INSERT` : Site node is inserted in the DB and all
`SiteEvents::INSERT` event listeners are processed.
* `SiteEvents::POST_UPDATE` : Site node is updated in the DB and all
`SiteEvents::UPDATE` event listeners are processed.
* `SiteEvents::POST_SAVE` : Site is inserted or updated in the DB and all
`SiteEvents::INSERT`, `SiteEvents::UPDATE`, and `SiteEvents::SAVE` event
listeners are processed.
* `SiteEvents::POST_DELETE` : Site is deleted from DB and all
`SiteEvents::DELETE` event listeners are processed.

## Hooks

The og_sm module also provides multiple hooks to make it easier to alter
functionality when a Site is involved.

> The hooks can be put in the `yourmodule.module` OR in the
> `yourmodule.og_sm.inc` file.
> The recommended place is in the yourmodule.og_sm.inc file as it keeps your
> .module file cleaner and makes the platform load less code by default.

### The site node is viewed

Will only be triggered when the node_view hook is triggered for a node type that
is a Site type.

```php
/**
* Implements hook_og_sm_site_view().
*
* @param &$build
* A renderable array representing the entity content. The module may add
* elements to $build prior to rendering. The structure of $build is a
* renderable array as expected by drupal_render().
* @param \Drupal\node\NodeInterface $site
* The site node.
* @param \Drupal\Core\Entity\Display\EntityViewDisplayInterface $display
* The entity view display holding the display options configured for the
* entity components.
* @param $view_mode
* The view mode the entity is rendered in.
*
* @see hook_node_view()
*/
function hook_og_sm_site_view(
array &$build,
\Drupal\node\NodeInterface $site,
\Drupal\Core\Entity\Display\EntityViewDisplayInterface $display,
$view_mode
) {
// ...
}
```

### Alter the Site homepage path

The `SiteManager::getSiteHomePage()` method creates and returns the url instance
to the frontpage (homepage) of a Site. That homepage is by default the Site node
detail page (node/[site-nid]).

Implementations can require that the homepage links to a different page (eg.
group/node/NID/dashboard).

This alter function allows modules to alter that path.

```php
/**
* Implements hook_og_sm_site_homepage_alter().
*
* @param \Drupal\node\NodeInterface $site
* The entity object.
* @param string $route_name
* The route name.
* @param array $route_parameters
* The route parameters.
*/
function hook_og_sm_site_homepage_alter(
\Drupal\node\NodeInterface $site,
&$route_name,
array &$route_parameters
) {
$route_name = 'og_sm.site.dashboard';
}
```
