[Gelöst] Retrieving multiple child post IDs

Hi

I'm having a problem getting multiple child ids. I'm using this to get the parent ID without a problem.

$parent_id = toolset_get_related_post( $id, 'doctors-at-clinic', 'parent');

Then I'm using this to get the children of the parent

$location_id = toolset_get_related_post( $parent_id, 'clinic-location', 'child');

If there is one child I get the ID but not for several children. I've tried using arrays but I'm not having any success.

Can you please help with the code. I just need each child post ID

Thanks

Hello. Thank you for contacting the Toolset support.

Well - Post relationship API function toolset_get_related_post is set to return only 1 value. As you can see with the following Doc:
=> https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/#toolset_get_related_post

You should use the Post Relationship API function toolset_get_related_posts in this case to retrieve all related posts.
=> https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/#toolset_get_related_posts

For example:

 $related_post_ids = toolset_get_related_posts(
                                     $parent_id,
                                     'clinic-location',
                                      'parent',
                                      100,
                                       0,
                                       array(),
                                      'post_id',
                                      'child'
                                      );

Thanks Minesh! That worked great.

I added this and I was able to get each ID which is what I needed.

foreach ($related_post_ids as $related_post_ids) {
echo $related_post_ids;
}
