Hi!

I created a loop for a custom post type. This custom post type has a post object field which links to another custom post type. So inside the loop of the custom post type i need to show data from the linked post. Actually after i called the post-object i cant get back to the default loop object after i reset the postdata. How can i after i show data from the linked data, again show data from the loop object?

<?php $loop = new WP_Query($args); ?>
<?php if ( $loop->have_posts() ) : while ( $loop->have_posts() ) : $loop->the_post(); ?>
<?php

// HERE STARTS THE POST OBJECT PART TO SHOW DATA FROM THE LINKED POST 
$post_object = get_field('kurs_zu_diesem_seminar');
                                
if( $post_object ): 

// override $post
$post = $post_object;
setup_postdata( $post ); 
?>

<h3><a href="<?php the_permalink(); ?>"><?php the_title(); ?></a></h3>

<?php wp_reset_postdata(); ?>
<?php endif; ?>
// END POST OBJECT PART

// START SHOW DATA FROM DEFAULT OBJECT
<span class="title"><?php the_title(); ?> am <?php the_field('start_datum'); ?></span>
<?php the_field('beschrieb'); ?>

<?php endwhile; ?>
<?php else: ?>
<p>Aktuell sind keine Seminare geplant.</p>
<?php endif; ?>
                                
<?php wp_reset_postdata(); ?>

Hi @leuchterits

I tested your code on my end and it works great. Could you please share the JSON or XML export of your field group so I can check your setup?

Also, you can always use the returned post as a post object like this:

<?php $post_object = get_field('kurs_zu_diesem_seminar'); ?>

<h3><a href="<?php echo get_permalink($post_object->ID); ?>"><?php echo $post_object->post_title; ?></a></h3>

I hope this helps. Thanks 🙂

Hi,
I had the same problem.
I made a loop on CPT and in each one I need a post-objet.

Here is what i made

<table>
<tr>
<td>Nom/Prénom</td><td>Numéro de téléphone</td><td >email</td><td>Commission</td>
</tr>    
        
     
<?php	while($author_posts_contacts->have_posts()) : $author_posts_contacts->the_post();?>
    <tr>
    	<td> <?php $id_post_origine=get_the_ID();?>//Register the "parent" post id
        <strong><?php the_field('titre_du_post'); ?> <?php the_field('nom_correspondant_festo'); ?></a></strong></br>
		<?php $post_object = get_field('structure'); if( $post_object ): 	$post = $post_object; setup_postdata( $post );	?>//Call the post object Inside and work with
(<?php the_title(); ?>)
<?php $post = $id_post_origine; setup_postdata( $post ); ////Call back the "parent" post datas

endif; ?>
        </td>
        <td><?php the_field('numero_de_telephone_correspondant_festo'); ?></td>
        <td><?php the_field('email_correspondant_festo'); ?></td>
        <td><?php $mots_cles = get_field('commission_correspondant_festo');
		foreach ($mots_cles as $mot_cle):
		$id_du_mot_cle = get_term( $mot_cle);
		echo $id_du_mot_cle->name.'</br>';
		endforeach;?>
        
		
</td></tr>
           
    <?php           
    endwhile;?></table>

I hope this helps.

<?php wp_reset_postdata(); ?>
↓
<?php $loop->reset_postdata(); ?>

<?php $loop = new WP_Query($args); ?>
<?php if ( $loop->have_posts() ) : while ( $loop->have_posts() ) : $loop->the_post(); ?>
<?php

// HERE STARTS THE POST OBJECT PART TO SHOW DATA FROM THE LINKED POST 
$post_object = get_field('kurs_zu_diesem_seminar');
                                
if( $post_object ): 

// override $post
$post = $post_object;
setup_postdata( $post ); 
?>

<h3><a>"><?php the_title(); ?></a></h3>

<?php $loop->reset_postdata(); ?>
<?php endif; ?>
// END POST OBJECT PART

// START SHOW DATA FROM DEFAULT OBJECT
<span class="title"><?php the_title(); ?> am <?php the_field('start_datum'); ?></span>
<?php the_field('beschrieb'); ?>

<?php endwhile; ?>
<?php else: ?>
<p>Aktuell sind keine Seminare geplant.</p>
<?php endif; ?>
                                
<?php wp_reset_postdata(); ?>
