我知道如何获取帖子的ACF字段，但我很难获得这些结果中的关系来返回ACF字段。

示例：

    $args = array(
        \'post_type\' => \'location\',
        \'post__in\'  => array(67)
    );
    $q = new WP_Query($args);
    $locations = array();
    while($q->have_posts()) : $q->the_post();
        $p = get_post(); // gets the basic post details
        $f = get_fields(); // gets the ACF details
        $m = array_merge((array)$p, (array)$f); // merges all details into one array
        array_push($locations, $m);
    endwhile;

这表明

Array
(
    [0] => Array
        (
            [ID] => 67
            [ACF_Field => This is a custom field/value.
            ...
            [ACF_Relationship_Field] => Array
                (
                    [0] => WP_Post Object
                        (
                            [ID] => 133
                            // there should be another [ACF_Fiel]/value here
                            ...
                        )
                )
        )
)

因此，数组的第一级中包含ACF值，但您可以看到第二级中没有。我看着the ACF Reference 这有助于我达到这一点，但不幸的是，我还没有找到任何能与ACF字段相关的关系。

foreach( $locations as $l ) {
   //grab post id
   $pid = $l[\'ACF_Relationship_Field\'][0]->ID;
   // grab fields
   $fields = get_fields($pid);
   // add them back. As ACF_Relationship_Field is an object I will add it next
   // to it, but you can do whatever you prefer
   $l[\'ACF_Relationship_Field\'][] = $fields;

}
