Actually lowercase post_id is the correct usage. Thanks!
Right now I have solved this by not using a post_object field type. Instead I’m using select field type and manually populating its choices via acf/load_field filter.
Initially I thought post_object field could handle everything automatically.
Yes, everything is registered in functions.php
1. add_action( 'init', 'registerPostTypes', 0 );
2. add_action( 'acf/init', 'addFieldsByLevel' );
3. In addFieldsByLevel function I’m looping through taxonomy terms and adding a field for each of the term (code in the earlier post).
And yes just before the loop I’m checking for the post ID which works on admin
if ( isset( $_GET['post'] ) ) {
$post_id = $_GET['post'];
} else if ( isset( $_POST['post_ID'] ) ) {
$post_id = $_POST['post_ID'];
} else {
return;
}
The fields are registered using acf/init action (with default priority 10) and the code is placed after CPT registration.
Is there a way to debug select2 ajax requests?
Aaand 10 months later I stumbled on this bug again.
I’m registering fields dynamically:
foreach( $levels as $i => $level ) {
$name = "level_{$level->term_id}_winner";
acf_add_local_field([
'parent' => 'group_5cb57c19cffde',
'key' => "field_{$name}",
'label' => sprintf( __( '%s level winner', 'imatch' ), $level->name ),
'name' => $name,
'type' => 'post_object',
'post_type' => [ 'im_registration' ],
'taxonomy' => [],
'allow_null' => true,
'return_format' => 'id',
]);
}
