I’m sorry, my mistake.
I had wrong filters for rule_match. Here’s the right code:
# Should we display this in a Page?
function acf_location_rules_match_wpml_page( $match, $rule, $options ) {
var_dump([$match, $rule, $options]);
}
add_filter('acf/location/rule_match/wpml_page', 'acf_location_rules_match_wpml_page', 1, 3);
It works now.
Thanks!
