Hello,
I try to use the query filter on post_object, it’s okay to add args in the query, for example, adding [‘posts_per_page’] = 7;
The goal is to show only 7 posts on the select field, but even with this arg, the list show all posts.
(I try [‘numberposts’] too, same result).
How can i limit results in a select field using post_object type.
By the way thanks for this useful plugin.
Hi @Romain9p
Looking at the source code, you need to use the numberposts param.
If that doesn’t work, perhaps the filter is not running correctly.
Can you post your code?
Thanks

Here it is !
I try numberposts whithout success, I don’t know if it’s important but for your information the select field list custom posts type.
add_filter('acf/fields/post_object/query/key=*my_field_key*', 'change_posts_order', 10, 3);
function change_posts_order( $args, $field, $post )
{
$args['numberposts'] = 7;
$args['sort_order'] = 'DESC';
$args['sort_column'] = 'date';
$args['orderby'] = 'date';
$args['order'] = 'date';
$args['post_status'] = 'publish';
return $args;
}
Thanks
Hi @Romain9p
Can you debug your filter by running this code before returning the $args:
echo '<pre>';
print_r($args);
echo '</pre>';
die;
Do you see the array printed?
Hi elliot,
Here the $args
Array
(
[numberposts] => 7
[post_type] => emission
[orderby] => date
[order] => date
[post_status] => publish
[suppress_filters] =>
[sort_column] => date
[sort_order] => DESC
)
How strange. Looks like the args are correctly being set,
Your next step is to find out why the args aren’t being read in by ACF by running a simple debug in the ACF code.
Edit the core/fields/post_object.php file and on line 171, can you print out the $args? Are the args taking ont he changes from your filter?
Thanks

Hi @elliot,
This is strange, $args are ok if I print it on core/fields/post_object.php at line 171.
Array ( [numberposts] => 7 [post_type] => emission [orderby] => date [order] => date [post_status] => publish [suppress_filters] => [sort_column] => date [sort_order] => DESC )
Hi @Romain9p
The only thing I can think of is that there is a filter running on the pre_get_posts which is overriding this setting.
Hopefuly that points you in the right direction.
Thanks

I resolved it !
I don’t know why but with my custom post type, in core/fields/post_object.php, it runs get_pages() function instead of get_posts() (maybe).
So I change the $args['numberposts'] by $args['number'] et voila !

I have a similar is issue when trying to do this:
function my_post_object_query( $args, $field, $post )
{
// filter by the posts current categories
$args['cat'] = implode(",", wp_get_post_categories($post->ID));
echo "<pre>";
print_r($args);
echo "<pre>";
return $args;
}
add_filter('acf/fields/post_object/query/key=field_524f02159316d', 'my_post_object_query', 10, 3);
The category filter is not picked up… same as above, the post_object.php is using get_pages() against a custom post type.
Suggestions other then changing the core file?
My Bad! … I had my custom post type set as “Hierarchical” change that to false and its good to go.
I just ran into this issue whereby filtering a post_object’s query wasn’t taking, but it looks like when a post_object’s type is ‘page’, ACF is effectively firing get_pages vs. creating a new WP_Query, so the args are all different.
So, running this choked:
$args['post_parent'] = $parent->ID;
$args['orderby'] = 'menu_order';
While running this works great:
$args['child_of'] = $parent->ID;
$args['sort_column'] = 'menu_order';
Hopefully this will help anyone else who’s wondering why this isn’t working properly.
