Getting crazy with Relation field

Hello,

i’ve readed doc on relation field, and it seems to be exactly what i need. Perhaps, i’m not able to get it work on front end. Maybe i’m doing something wrong ?

my process :

i have a travel guide site, and i wish to link custom posts to a city.
so i have custom posts : hotel, camping, etc… and also a custom post called “region” where are all the cities.

In my custom post i added a relation field, linked to the region custom post.

So in each of my hotels, campings, etc… to display “hotel located in CITY”
and in my city pages, i want to display “hotels in CITY”.

i’ve tried both code examples for single-doctor.php & single-location.php i can not have any data displayed. For single doctor, i even have an error message.

# my single location

in my single location, i’m tring to display all the markets of this city.
so i call a function called : be_list_market_in_city()

and my function is :

	function be_list_market_in_city() {

		echo get_the_ID();
		$args = array(
				'post_type' => 'marche',
				'meta_query' => array(
					array(
						'key' => 'contact_city', // name of custom field
						'value' => '"' . get_the_ID() . '"', // matches exactly "123", not just 123. This prevents a match for "1234"
						'compare' => 'LIKE'
						)
					)
				);

						
		$query = new WP_Query($args);
		if ($query->have_posts() ) : while ( $query->have_posts() ) : $query->the_post();
			$title = get_the_title();
			echo $title. '<br />';
		endwhile;
		wp_reset_postdata();
		endif;
	}

As you can see, i echo get_the_id() to be sure i have the good ID, and on front, i do have ID 1112 display ( 1112 is the right ID for the location )

But i have no results returned.
If i take of the meta_query filter, i do have all the market listed.

What am i doing wrong ?

#my single hotel

in my single hotel, i just made a try with your code in doc, just changing my CPT

						<?php 
						$locations = get_field('contact_city');
						?>
						<?php if( $locations ): ?>
							<ul>
							<?php foreach( $locations as $location ): ?>
								<li>
									<a href="<?php echo get_permalink( $location->ID ); ?>">
										<?php echo get_the_title( $location->ID ); ?>
									</a>
								</li>
							<?php endforeach; ?>
							</ul>
						<?php endif; ?>

And this return :

Warning: Invalid argument supplied for foreach() in /home/xxx/zz_dns/xxx/wp-content/themes/xxx/template-parts/content-hotelsdetail.php on line 127

i add a capture of my settings (in french) for this field :

Thanks in advance for your precious help in solving this issue.

For information, a var_dump of $locations

gives

string(56) “https://urlofactualpage”
