Hi Elliot 🙂 !

I have a question for you.

I have 2 custom post types :
product and event

Thanks to your “Post Object” field, each event can be “linked” to a product. As I’ve understood, your “Post Object” field returns an post object. On a single product page, I would like to display the events linked to the current product.

Example :

I have 2 events that are linked to the product “Blue product”. On the “Blue product” single post page, I would like to display the 2 events.

I’ve tried that but it doesn’t work…

$args = array ( 
      'post_type'       => 'event',
		  'orderby'         => 'title',
		  'order'           => 'asc',
      'meta_query'      => array(
    		array(
    			'key'     => 'post_object_field',
    			'value'   => get_post($post->ID),
    			'compare' => '='
    		)
    	)
    );  
    $events = get_posts($args);

Could you please help me ?

Thank you !

Hi @cedric_charles

There are 2 possible issues with the above code:
1. Is the key ‘post_object_field’ your field name
2. The value should be just the post_id, not the object.

It is most likely issue #2

Hope that helps

Thanks

Hi @elliot

1. ‘post_object_field’ was not the real field name, I give this to you because the real name was a weird french word, so I thought it was easier for you to understand this name 😉 !

2. You are right ! It had to be just the post_id, thanks ! But why ? the ACF field returns an object so why do I have to compare to just the object’s ID ?

Thanks for your help 🙂 !

Hi @cedric_charles

Thanks for the follow up.
The get_field will return an object, but it only saves an ID into the DB. This is why you need to search for only the ID.

Thanks
