Will get value from an Advanded Custom Field recursively. Meaning traversing up until value is found.

get-field-recursive.php

<?php

/* 
 * Get ACF fields recursivly
 * (if post does not have value look upward until found)
 */

function get_field_recursive( $field, $level_id = null ) {
	// If no ID is passed set to post ID
	$level_id = $level_id == null ? get_queried_object_id() : $level_id;
	$return_value = get_field($field, $level_id);
	$ancestors = get_post_ancestors($level_id);

	if ( $return_value ) {
		// Return field value when found
		return $return_value;
	} else if ( $ancestors ) {
		// Get closes ancector: http://codex.wordpress.org/Function_Reference/get_post_ancestors
		$level_id = $ancestors[0];
		return get_field_recursive($field, $level_id);
	} else {
		// Return false if value is not found nor have ancestors
		return false;
	}
}

?>

Just what I needed :) Thnx for sharing!
