Getting The First Two Rows of a Repeater and Then Outputting a Nested Repeater

I’m in a little over my head on this one. I’m try to do two different tasks here:

1. Get the first row of a repeater. Got that working.

2. There’s a nested repeater in each of that row. I want to get that and loop through, but not sure of the syntax.

Outer repeater is “press_releases”
Inner repeater is “pr_posts”
My code:

<?php if( have_rows('press_releases') ): ?>
<h2>Press Releases <span class="sprite icon"></span></h2>
<div>
<?php endif; ?>

<?php
   $prRows = get_field('press_releases' ); // get all the rows
   $first_row = $prRows[0]; // get the first row
   $first_row_year = $first_row['year'];
   $first_row_pr = $first_row['pr_posts'];
?>

<h3><?php echo $first_row_year; ?></h3>

<?php
   $pr_posts = get_field('pr_posts' ); // get all the rows
   $pr_rows = $pr_posts[0]; // get the first row
									   
   if($pr_rows) {
   foreach($pr_rows as $rows)
      {
         echo '<h4>Test</h4>';
      }
   }
?>

Working with nested repeaters is a large topic. Have you seen this tutorial http://www.advancedcustomfields.com/resources/working-with-nested-repeaters/

Let me know if that doesn’t help.

John,
Yeah, the complication that’s throwing me through a loop (pun intended) is the getting the first row and then the syntax to loop through that nested repeater.

Just typing it up here and formatting it helped me work it out in my head:

<?php if( have_rows('press_releases') ): ?>
<h2>Press Releases <span class="sprite icon"></span></h2>
<div>
<?php endif; ?>

<?php
   $prRows = get_field('press_releases' ); // get all the rows
   $first_row = $prRows[0]; // get the first row
   $first_row_year = $first_row['year'];
   $first_row_pr = $first_row['pr_posts'];
?>

<h3><?php echo $first_row_year; ?></h3>

<?php
   if($first_row_pr) 
      {
         foreach($first_row_pr as $pr)
         {
            echo '<h4><a href="#">' . $pr['heading'] . '</a></h4>';
            echo '<p>' . $pr['date'] . '</p>';
         }
      }
?>

Edited: answered it yourself before I could finish typing. Sometimes typing it out does help. That’s how I do my thinking most of the time.

…..

Maybe this code for a nested repeater stripped of all the extra stuff will help.

if (have_rows('parent_repeater')) {
    while (have_rows('parent_repeater')) {
        the_row();
        if (have_rows('nested_repeater')) {
            while (have_rows('nested_repeater')) {
                the_row();
                $value = get_sub_field('sub_field_of_nested_repeater');
            }
        }
    }
}

So basically you have two nested loops that are identical.
