ACF changes not caching

Hi @brunodeangelis

Thank you for using our plugin!

What plugin are you using to add the ACF fields to the REST API? Because out-of-the-box ACF fields aren’t added to the REST API output.

However it should work correctly. I just did a test without any extra plugin (so only ACF and WP REST Cache enabled) and the caches were flushed when I changed the value of an ACF custom field.
We use ACF all the time together with the ACF to REST API plugin (https://ww.wp.xz.cn/plugins/acf-to-rest-api/) and haven’t had any issues with the cache not being flushed when editing a custom field value.

Hi @brunodeangelis

Am I correct in assuming these endpoints are custom endpoints which you have enabled caching for? And are these also the endpoints with flush issue? Because if that is the case it might not have anything to do with ACF, but any field you edit might cause the cache not to be flushed.
What does the Object Type column for those endpoints say? If it says unknown than that is the problem. Our plugin cannot determine the object type of the item(s) in the endpoint and therefore it does not know when to flush it. See our FAQ to help our plugin determine the correct object type.

Hi @brunodeangelis

Without knowing the contents of the endpoints and what post types you are using, it is hard for me to write some code for you. But I will try to help you:

Am I right in assuming that propiedad and empendimiento are custom post types? If so our plugin should be able to determine there post types (= object types) automatically. However if the id and/or the type isn’t presentin the REST result (because you might have filtered it out) than our plugin can not determine the correct object type. Easiest solution would be to make sure id and type are present.

If for some reason you can not add those you could use the filter as described in our FAQ, something like this should work:

function wprc_determine_object_type( $object_type, $cache_key, $data, $uri ) {
	if ( $object_type !== 'unknown' ) {
		return $object_type;
	}
	if ( false !== strpos( $uri, 'propiedad') ) {
		return 'propiedad';
	}
	if ( false !== strpos( $uri, 'empendimiento') ) {
		return 'empendimiento';
	}
	return $object_type;
}
add_filter( 'wp_rest_cache/determine_object_type', 'wprc_determine_object_type', 10, 4 );

Please delete all unknown caches after applying this code.

Hi @brunodeangelis

We don’t use the _envelope=1 query param (we get the amount of posts from the response headers), but I just did a test and it doesn’t crash. Could you have a look in your error logs to see what the exact error is?

Edit: but now I do notice that the cache with the _envelope parameter doesn’t detect the object type correctly. I will add this to our todo-list, because it should be able to detect it automatically.
