Repeater within a repeater options page – grab data from first repeater loop

Hi, this might be a bit complicated to explain so bare with me (couldn’t even summarise it in the topic.) the image and code below should summarise

Essentially I want the document link to display on the post object pages within the sub-repeater field. I’ve managed to get the code working without a sub-repeater (post object only) but that means the document can only be displayed on one page… which isn’t ideal as the client wants the documents accessible on multiple pages – as well as being more user friendly in regards to organising documents (they add and remove documents frequently)

<?php if ( have_rows('documents2', 'option') ) :  
  $currentPageID = $post->ID;
  $countCheck = 0;

  while ( have_rows('documents2', 'option') ) : the_row(); 

    if ( have_rows('document_pages') ) : 

      while ( have_rows('document_pages') ) : the_row(); 

        $post_object = get_sub_field('document_page');

        if ($post_object->ID == $currentPageID) {
          $countCheck++;
        }
    
      endwhile; 

    endif; 

  endwhile;

This is working properly – it’s counting both instances of homepage.

  if($countCheck > 0): 
  ?>

      <div class="documents">
        <div class="container">
          <div class="row">
            <div class="col-xs-12 col-md-8 col-md-offset-2">
              <h2 class="text-center">Documents</h2>
              <?php 
              $documentCategories = array();

              while ( have_rows('documents2', 'option') ) : the_row();
      
                if ( have_rows('document_pages') ) :  

                  while ( have_rows('document_pages') ) : the_row(); 
                  $post_object = get_sub_field('document_page');

                    if ($post_object->ID == $currentPageID) {

This is where the code begins to falter – I want to go back to the parent repeater and display the respective category on the page – but as it’s a parent loop within a parent loop it loops infinitely (i believe… or at least the page times out with a 501 error!)

  if ( have_rows('documents2', 'option') ) :  

                        while ( have_rows('documents2', 'option') ) : the_row(); 
                        $terms = get_sub_field('document_category2');
              
                          if( $terms ): 
                            
                            foreach( $terms as $term ):
                            $tag = $term->name;
                            
                    
                              echo $tag;
                              
                            endforeach;
                        
                          endif;

                        endwhile;
                    
                      endif;

                    } 

                  endwhile;

                endif;

              endwhile;

              ?>
            </div>
          </div>
        </div>
      </div>

  <?php endif; ?>

<?php endif; ?>

I’ve tried a break and return but it means losing the $post_object data… any help would be much appreciated 🙂

Hi @tdoc42

You are not supposed to loop trough the parent repeater again in your code. You should be able to get the ‘document_category2’ subfield after the child repeater loop. It should be something like this:

while ( have_rows('documents2', 'option') ) : the_row();
      
    if ( have_rows('document_pages') ) :  

        while ( have_rows('document_pages') ) : the_row(); 
            $post_object = get_sub_field('document_page');

            if ($post_object->ID == $currentPageID) {
                // do something here
            }
        endwhile;
        
    endif;
        
    // you can access the subfields of "documents2" again here
    $terms = get_sub_field('document_category2');

endwhile;

This page should give you more idea about it: https://www.advancedcustomfields.com/resources/working-with-nested-repeaters/.

I hope this helps 🙂

Sorry – I may not have made myself clear – I want to grab the terms/categories from within the if ($post_object->ID == $currentPageID) so only the documents connected to the post object display on the respective page.

The method you have sent me grabs ALL of the terms/categories and displays it on all pages…

Just to reiterate, the client wants the document uploader to be accessible through one page (options) rather than on a page by page basis, as it is too difficult for them to organise.

Hi @tdoc42

If you want to use it inside of the child repeater loop, then you need to put the terms in a variable first. It should be something like this:

while ( have_rows('documents2', 'option') ) : the_row();
      
    if ( have_rows('document_pages') ) :  
    
    // get the terms and put it in a variable for later use
    $terms = get_sub_field('document_category2');

        while ( have_rows('document_pages') ) : the_row(); 
            $post_object = get_sub_field('document_page');

            if ($post_object->ID == $currentPageID) {
                // you can use the $terms variable here
                print_r($terms);
            }
        endwhile;
        
    endif;

endwhile;

I hope this makes sense 🙂

thanks, putting $terms before the if (have_rows(‘document_pages’) ): does the trick, should have known! thank you 🙂
