Getting ACF relationship field information

Relationship fields can either return an Objects or a Post IDs. That’s up to you (you can choose it when creating the field). Either way that object or ID would be returned inside an array, because the field gives you the option to select multiple values.

So in your loop:

$members = get_field('committee_members'); // assuming that's the field slug

//if it's returning the object

foreach($members as $member){

  echo $member->post_title; //member name

}

That would assign all Committee Members to $members. Then you just need to loop through all $members and print their name, or anything else you need that’s related to that post. If the Committee Member also has ACF custom fields you can access it by using:

get_field("YOU_FIELD_NAME", $member->ID);
