This WordPress mu-plugin enables group caching for sites using the [Redis Object Cache for WordPress](https://github.com/devgeniem/wp-redis-object-cache-dropin) dropin.

Installation
------------

[](#installation)

Install with composer:

```
$ composer require devgeniem/wp-redis-group-cache

```

OR add it into your `composer.json`:

```
{
  "require": {
    "devgeniem/wp-redis-group-cache": "^3.0.0"
  }
}
```

Functionalities
---------------

[](#functionalities)

### Creating the cache group

[](#creating-the-cache-group)

Defining a group for WP Object Cache items enables simultaneous cache invalidation for a set of cache items. See the [codex](https://codex.wordpress.org/Function_Reference/wp_cache_set) for further information on setting the group key. The following functions create the object cache functionality by hooking to the Redis Object Cache dropin:

**add\_to\_group**

This function is hooked to the cache setting with the `wp_cache_set` function. If a group key is set for `wp_cache_set`, the cache key is pushed into a Redis hash list mapped by the group key.

**delete\_from\_group**

This function is hooked to the cache deletion with the `wp_cache_delete` function. If a group key is set for `wp_cache_delete`, the specified item key is removed from the group list. This ensures the group only has keys that actually exist in the object cache.

### Invalidating a cache group

[](#invalidating-a-cache-group)

**delete\_group**

This function deletes all data related to a group key by first fetching all keys and deleting them from Redis and then deleting the Redis hash list of the group.

Usage:

```
\Geniem\GroupCache::delete_group( $group_key );

```

Excluding custom or including default groups to caching
-------------------------------------------------------

[](#excluding-custom-or-including-default-groups-to-caching)

The Redis dropin automatically caches all data stored with WordPress Object Cache into Redis. If you want to modify which groups are stored you can use the two filters `geniem/cache/no_group_cache/blacklist` and `geniem/cache/no_group_cache`.

### Modifying the blacklist

[](#modifying-the-blacklist)

If you want to include some default groups like `acf` or `transient` or exclude custom ones for example from plugins that use it, you can use the `geniem/cache/no_group_cache/blacklist` filter to modify an array of blacklisted groups.

```
function group_cache_blacklist( array $groups ) : array {
	$groups[] = 'customgroup';
	return $groups;
}
add_filter( 'geniem/cache/no_group_cache/blacklist', 'group_cache_blacklist', 1, 1 );
```

#### Exluded groups by default

[](#exluded-groups-by-default)

[classes/cache.php](classes/cache.php#L109)

### More specific selection if a group should be excluded

[](#more-specific-selection-if-a-group-should-be-excluded)

You can do a more direct check if a group should be exluded by using the `geniem/cache/no_group_cache` filter. *Note this is applied after the blacklist check, so if the group is already on the blacklist this will not be checked.*

```
function no_group_cache( string $group, string $key ) : bool {
    if ( 'no_caching_key' === $group ) {
        return true;
    } else {
        return false;
    }
}
add_filter( 'geniem/cache/no_group_cache', 'no_group_cache', 1, 2 );
```

*Note that this does not disable the initial key-value caching!*
