Hi @energystar

I would suggest that you change your field from a repeater with a post object field to a relationship field instead.

That way you’ll get a single meta value containing a serialized array of post IDs and you can do the query you want using this:

<?php
global $post; // This will be your post_type1 post object.
$args = array(
	'post_type' => 'post_type2',
	'posts_per_page' => 10000, // Should never be set to -1 as it's a risk not setting boundaries. Good code practise!
	'no_found_rows' => true, //Disables the use of pagination BUT saves us an additional query. Remove if you need pagination
	'update_post_term_cache' => false, //Does not update a potentially old cache of the queried posts term relationships BUT saves us an additional query. Remove if you're going to display term info
	'meta_query' => array( //Query the serialized array. Putting the value in quotes makes sure we dont get a hit on 1234 when we search for 123. 
		array(
			'key' => 'relationship_fieldname',
			'value' => '"' . $post->ID . '"',
			'compare' => 'LIKE'
		)
	)
);

Doing the same thing with repeaters are a lot more complex and more expensive performance-wise.
