Im currently trying to add a post_object field to a custom post type ‘course’
The post_object (with key: field_foo) should display a filtered collection of the custom post type ‘course-group’.
Showing all ‘course-group’ posts is not a problem, but I need to achieve the following:
Each ‘product’ has a ‘courseid’ field key with an ID for that course.
Furthermore each ‘product-type’ has a matching ‘field_courseid’ field matching a ‘product’ id.
How can I display only the ‘course-group’ posts in the ‘post_object’ that match the current ‘course’?
I had tried the following (with a hardcoded number), but it did not work:
function foofunc($args, $field, $post_id) {
$args[‘meta_query’] = array(
array(
‘key’ => ‘field_courseid’,
‘value’ => ‘6’,
‘compare’ => ‘==’,
),
);
return $args;
}
add_filter(‘acf/fields/post_object/query/key=field_foo’, ‘foofunc’, 10, 3);
Even worse, just adding a function that only returns $args already breaks the post_object, causing it to return only the normal posts (and not the wanted custom posts of ‘course-group’)
Are you saying that if you do this
add_filter('acf/fields/post_object/query/key=field_foo', 'foofunc, 10, 3);
function foofunc($args, $field, $post_id) {
return $args;
}
that it breaks the field?
