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.
