Hello!

I have 3 post types (banks, developers, building).

Post in post type “building” have post object custom field, that refers to banks. (There I bring the banks that issue mortgage on the building).

On single page “banks” I was able to display posts. But i have a trouble.

I can not get post on single bank page, which referred to the bank from post type “building”.

Example (I have the following links):

Building (post type):
First building -> First bank, second bank
Second building -> Second bank
Third building -> First bank

I want to on the banks of the page displays the following information:

First bank -> First building, Third building
Second bank -> First building, Second building

That is, the relationships that I have pointed out previously.

In post type “building” i use custom field “ns_zastroyschik”.

Sorry for my English.

I find the solution!

<?php 
						/*
						*  Query posts for a relationship value.
						*  This method uses the meta_query LIKE to match the string "123" to the database value a:1:{i:0;s:3:"123";} (serialized array)
						*/

						$buildings = get_posts(array(
							'post_type' => 'novostroyki',
							'meta_query' => array(
								array(
									'key' => 'ns_zastroyschik', // name of custom field
									'value' => '"' . get_the_ID() . '"', // matches exaclty "123", not just 123. This prevents a match for "1234"
									'compare' => 'LIKE'
								)
							)
						));

						?>
						<?php if( $buildings ): ?>
							<ul>
							<?php foreach( $buildings as $building ): ?>

								<li>
										<?php echo get_the_title( $building->ID ); ?>

								</li>
							<?php endforeach; ?>
							</ul>
						<?php endif; ?>

Thanks!
