Examples

#1 Purge the cache when a post is updated on siteground.com hosting

siteground.com hosting uses Dynamic Caching, which may cache custom requests and not purge them when posts are updated, even when the hosting provider's SG Optimizer plugin is installed. This can be done manually in the plugin, but it can also be automated using the plugin's sg_cachepress_purge_cache() function.

add_action( 'post_updated', 'purge_cache_after_post_updated' );

public function purge_cache_after_post_updated() {
	static $skip_purge = false;

	if ( $skip_purge || ! function_exists( 'sg_cachepress_purge_cache' ) ) {
		return;
	}

	$skip_purge = true;

	add_action( 'shutdown', function () {
		sg_cachepress_purge_cache();
	} );
}
