It was returning an ID, now I’ve changed it to return an object (in the Back-End) and also changed the code, previously I was receiving the following message:
Trying to get property of non-object in… (same as above).
The final code:
$query = new WP_Query($args);
if ($query->have_posts()) :
while ($query->have_posts()) : $query->the_post();
?>
<?php $i = 0;?>
<?php if($i == 0){ echo "<tr>"; }?>
<td>
<?php
$artista_evento = get_field('artista_del_evento');
foreach ($artista_evento as $av) {
echo get_the_title( $av->ID );
}
?>
</td>
<?php $i++;?>
<td><?php the_field('fecha_del_evento'); ?></td>
<?php $i++;?>
<td><?php the_field('lugar_del_evento'); ?></td>
<?php $i++;?>
<td><?php echo get_the_content(); ?></td>
<?php $i++;?>
<?php if($i == 4){ echo "</tr>"; $i=0;}?>
<?php endwhile; ?>
<?php if($i < 4) echo '</tr>'; ?>
</table>
<?php wp_reset_postdata(); ?>
