nice one elliot! this leads me to the right direction. but i think i found a bug?! i am using ACF 5.0.3.
this is my function:
/* auto populate acf field with comment IDs */
function my_acf_load_field( $field ){
$assignedpost = get_field('produktblog');
$comments = get_comments(array(
'status' => 'approve',
'post_id' => $assignedpost->ID
));
if( is_array($comments) )
{
foreach( $comments as $key=>$comment )
{
$field['choices'][ $key ] = $comment->comment_content;
$field['default_value'][ $key ] = $comment->comment_ID;
}
}
return $field;
}
// v4.0.0 and above
add_filter('acf/load_field/name=kommentare', 'my_acf_load_field');
and this is the print_r from $field:
Array
(
[ID] => 150
[key] => field_53e327ee805e6
[label] => Kommentare
[name] => kommentare
[prefix] =>
[type] => select
[value] =>
[menu_order] => 0
[instructions] =>
[required] => 0
[id] =>
[class] =>
[conditional_logic] => 0
[parent] => 6
[_name] => kommentare
[_input] =>
[_valid] => 1
[choices] => Array
(
[0] => kommentar3
[1] => kommentar2
[2] => kommentar1
)
[default_value] => Array
(
[0] => 7
[1] => 6
[2] => 5
)
[allow_null] => 1
[multiple] => 1
[ui] => 0
[ajax] => 0
[placeholder] =>
[disabled] => 0
[readonly] => 0
)
the select field accepts the choices but not the values:

so as you can see, the value is still 0,1,2. but it has to be 7,6,5
