Hi all,
I have 2 custom post types:
– Homes
– Places
In homes, I have a Post Object relationship field to select a Place. The field it is set to return the object instead of the ID – if that makes a difference.
Now, in Places post type I am trying to setup a relationship field, that will show items from the Homes post types. But I also want to filter them based on the Place ID that is currently edited.
I found some topics in the forum, like this one:
https://support.advancedcustomfields.com/forums/topic/how-can-i-filter-a-posts-relationship-field-by-the-current-category-edit-screen/
I wrote my function:
function related_homes( $args, $field, $post_id ) {
$meta_query[] = array(
'key' => 'place',
'value' => $post_id,
'compare' => 'LIKE'
);
$args['meta_key'] = $meta_query;
// return
return $args;
}
But I get no matches.
Could someone offer some insights on how to go for it?
Also, how I could go to var_dump() the $args, $field etc for debugging purposes in this function?
It’s using ajax and if I var_dump I simply get nothing.
First question, does your post object field allow multiple of single values. If it contains multiple then you query is close, it should be
array(
'key' => 'place',
'value' => '"'.$post_id.'"',
'compare' => 'LIKE'
);
If it only contains 1 then it should be
array(
'key' => 'place',
'value' => $post_id
'compare' => '='
);
The next problem is with what your returning for args
function related_homes( $args, $field, $post_id ) {
// since $meta_query array does not exist yet you shouldn't use
// $meta_query[] =
$meta_query = array(
array(
'key' => 'place',
'value' => $post_id,
'compare' => 'LIKE'
)
);
// the correct argument key is 'meta_query'
$args['meta_query'] = $meta_query;
// return
return $args;
}

In the above function, is it possible to get the post_type somehow?
I am thinking to use this same field in more post_types, so it would be nice if I could do something like:
if ('places' = $post_type) {
$meta_query = array(
array(
'key' => 'place',
'value' => $post_id,
'compare' => 'LIKE'
)
);
$args['meta_query'] = $meta_query;
}
I tried global $typenow but it didn’t do it.
My other option is to create additional field groups…
$post_type = get_post_type($post_id);
@hube2
yes, of course!
It was that simple and right in front of me – feeling a bit silly now.
Thanks!!
