Cache driver

You can create your own custom cache drivers by extending one of the existing drivers or the base Cache class.

Extending an existing cache driver

To modify only parts of an existing driver like the FileCache, you can extend that class and selectively overwrite individual methods, e.g. the flush() method in this example:

class CustomCache extends Kirby\Cache\FileCache
{
    public function flush(): bool
    {
        // your custom code
        // ...

        return parent::flush();
    }
}

You then have to register the new cache type with Kirby's plugin wrapper:

Kirby::plugin('yourname/custom-cache', [
    'cacheTypes' => [
        'custom' => CustomCache::class
    ]
]);

Extending the Cache class

Alternatively, you can extend the Cache class to implement a new cache driver.

class SuperCache extends Kirby\Cache\Cache
{
    //implement methods here
}

As before, you have to register the new cache driver:

Kirby::plugin('yourname/super-cache', [
    'cacheTypes' => [
        'super' => SuperCache::class
    ]
]);
