Loop through post content from another post

Hello,

So I have some issues getting this thing to work. My scenario:

I have a post called “Project 1” which is a CPT where I have a post object link which I set to get another CPT post called “Content 1”. Content 1 has a title and a repeater field. “Project 1” has a lot of different fields which works fine but I would like to include the repeater field from “Content 1” on the “Project 1” page. I will also build a filter segment based from the fields in the repeater field from “Project 1”.

I thought I could use the post object example and return the content from “Content 1” but it’s not working. This is my code:

<?php $featured_posts = get_sub_field('apartmentlink');
if( $featured_posts ): ?>
	<ul>
		<?php foreach( $featured_posts as $post ): 
			setup_postdata($post); ?>
      <li>
          <?php the_title(); ?>
          <?php if( have_rows('apartment') ): ?>
  					<?php while( have_rows('apartment') ) : the_row(); ?>
  						<?php the_sub_field('number'); ?>			
  					<?php endwhile; ?>
				<?php endif; ?>
      </li>
  	<?php endforeach; ?>
    </ul>
	<?php wp_reset_postdata(); ?>
<?php endif; ?>

Problem is that it does only return the title of “Project 1” 24 times and nothing else. What am I doing wrong? I can’t understand why 24 times either.

I don’t see any reason, given the code above, why it should not be working.

However, the fact that it is outputting the title 24 times leads me to think you have a problem outside of this code.

Is this code inside a have_posts() loop? If yes, how is the query for that loop done? Is it the main WP query or is it a new custom query?

Alright, well I’m running roots / sage which shouldn’t make much difference.

I have a template for the “Project” posts which looks like this:

{{--
  Template Name: Projekt
--}}

@extends('layouts.app')

@section('content')
  @while(have_posts()) @php the_post() @endphp
    @include('partials.content-projekt')
  @endwhile
@endsection

And then I have content-single-projekt page which takes care of the flexible content and it looks like this:

@include('partials/section-hero')

@include('partials/section-intro')

<?php if( have_rows('content') ): ?>
	<?php while( have_rows('content') ): the_row(); ?>
    
		<?php if( get_row_layout() == 'projectfacts' ): ?>
			<h1>stuff here</h1>

		<?php elseif( get_row_layout() == 'apartmentlayout' ): ?>
			@include('partials/section-apartment')

		<?php endif; ?>
	<?php endwhile; ?>
<?php endif; ?>

And lastly my section-apartment looks like the example up top.

Your issue is that you are using include() to include template parts instead of get_template_part(). When you use include() none of the needed global variables are defined when the included file is run.

Alright, I did some more tampering and removed the include() and put the same code there like this:

<?php elseif( get_row_layout() == 'apartmentlayout' ): ?>
			<?php $featured_posts = get_sub_field('apartmentlink');
			if( $featured_posts ): ?>
				<ul>
					<?php foreach( $featured_posts as $post ): 
						setup_postdata($post); ?>
			      <li>
			          <?php the_title(); ?>
			          <?php if( have_rows('apartment') ): ?>
			  					<?php while( have_rows('repeater_field_name') ) : the_row(); ?>
			  						<?php the_sub_field('number'); ?>			
			  					<?php endwhile; ?>
							<?php endif; ?>
			      </li>
			  	<?php endforeach; ?>
			    </ul>
				<?php wp_reset_postdata(); ?>
			<?php endif; ?>

		<?php endif; ?>

I still get the same issue with 24 titles after eachother with the title from the current post I’m at.

So I tried this:

<?php elseif( get_row_layout() == 'apartmentlayout' ): ?>
			<?php echo '<pre>';
    		print_r( get_sub_field('apartmentlink')  );
			echo '</pre>';
			die; ?>

		<?php endif; ?>

And that on the other hand returns the correct post like this:

WP_Post Object
(
    [ID] => 73284
    [post_author] => 11
    [post_date] => 2022-09-19 08:39:19
    [post_date_gmt] => 2022-09-19 06:39:19
    [post_content] => 
    [post_title] => Content 1
    [post_excerpt] => 
    [post_status] => publish
    [comment_status] => closed
    [ping_status] => closed
    [post_password] => 
    [post_name] => content-1
    [to_ping] => 
    [pinged] => 
    [post_modified] => 2022-09-19 08:54:00
    [post_modified_gmt] => 2022-09-19 06:54:00
    [post_content_filtered] => 
    [post_parent] => 0
    [guid] => //localhost:3000/?post_type=apartments&p=73284
    [menu_order] => 0
    [post_type] => apartments
    [post_mime_type] => 
    [comment_count] => 0
    [filter] => raw
)

So it doesn’t seem to work even without include

Your problem starts all the way back in your main template

@include('partials.content-projekt')

the file loaded here will not have global variables it needs, like $post (the current post) or $wp_query (the main query) along with a host of others.
