Hi there,

I have a custom post type (books) with a repeater field (book_reviews), which then has 3 subfields. What I am trying to do is display all the reviews for all the posts in this custom post type. I have had no problem using the code (below) in the bodies of other sites, however, this site is different as I am trying to use the code in the header. I’m sure I am missing something simple but I cannot get the reviews to display when I put the code into the header (I’ve tried multiple ways of inputting the code including straight into header.php, creating a sidebar, and also using a template_part).

Here is the code I’m using

 <?php
wp_reset_query(); 
$my_secondary_loop = new WP_Query(array( 
	'post_type' => 'books',
        'showposts' => -1,
		'order' => 'ASC' )
);
if( $my_secondary_loop->have_posts() ): ?>

<?php if( have_rows('book_reviews') ):
			echo '<ul>';
    while( $my_secondary_loop->have_posts() ): $my_secondary_loop->the_post();

				while ( have_rows('book_reviews') ): the_row(); 
			 		
					// display the reviews
					echo '<li class="quotes"><span class="b-revs">';
					the_sub_field('review');
					echo '</span>';
					if (get_sub_field('reviewer_credentials') ) :
						echo '<span class="b-revcred">';
						the_sub_field('reviewer_credentials');
						echo '</span>';
					endif;
					echo '<span class="b-revname">';
					the_sub_field('reviewer_name');
					echo '</span>';

					echo '</li>';
			
 				endwhile; 
	endwhile; echo '</ul>'; 
else:  endif; wp_reset_query();  endif; // end of the loop. ?>

Hi @kikadesign

Since you are outside the loop, you will have to also pass in the Post ID (using get_the_id()) when using: have_rows in the format:
while ( have_rows('book_reviews', get_the_id()) ): the_row();

However, with the above code… you cannot pass in the ID until after this line:
while( $my_secondary_loop->have_posts() ): $my_secondary_loop->the_post();

So… you will have to come up with different logic to check if there are any rows, and to wrap your unordered list, but I imagine this will get you on the right track.

Please mark as resolved or feel free to ask more q’s if needed.. I will subscribe to this thread.

Thank you for your help, Keith! I’m not sure why I didn’t mark this as resolved. Very sorry and you are very appreciated!
