Filter collection by field inside object field

The CMS Questions
1

I thought I had the code for this figured out, but this isn’t behaving the way it ought to. (It isn’t returning any results, when it should match a page.) Can someone help me troubleshoot?

$activity = "Hiking"; /* for example */

$calendar = $all_calendarItems->filter(function ($p) use ($activity) {
	return in_array(
		$activity,
		$p
			->facts() /* facts is an object field */
			->toObject()
			->activity() /* activity is a multiselect field */
			->split()
	);
});

Sure your activity is stored starting with a capital letter?

Yes, definitely.

Ok, and what do you get when you dump($calendar)? Note that the code should work fine, provided that a) the field names (facts and subfield activity are correct, b) $ $all_calendarItems is a pages collection. Maybe post what is stored in one of the content files you are filtering..

Argh! While preparing another sample set of data to post here, I realized the issue resulted from a separate issue in the logic of this page’s controller. I should have realized that earlier, since I don’t trust myself with this complex filtering, I assumed that was the culprit. I’m all good now, and as you confirmed, the code I posted initially does work as intended. Thanks for your help.
