Hi,

I have a Flexible content group with 2 columns. 1 for title and one for anchor id.
See pic 1.

I’m trying to loop out the anchor links(id) and the title like this:

<?php
$links = get_sub_field('links');
?>

 <?php foreach ($links as $link) :
      
        $anchor = ($link['id']) ? 'href="#' . $link['id'] . '"' : "";
      ?>
        <li class="side-menu__item"> 
          
        <a class="menu__link" <?= $anchor ?>>
            <?= $link['title']; ?>
          </a>
        </li>
      <?php endforeach ?>

I’m doing this on the frontpage, however i get no data. It shows nothing.

when I do <?php var_dump($links); ?> i get bool(false)

get_sub_field() needs to be used inside of a have_rows() loop.

Okay so something like this?

  <?php if( have_rows('links') ): ?>
      <?php 
       $links = get_sub_field('links');
      foreach ($links as $link) :
        $anchor = ($link['id']) ? 'href="#' . $link['id'] . '"' : "";
      ?>
        <li class="side-menu__item"> 
          
        <a class="menu__link" <?= $anchor ?>>
            <?= $link['title']; ?>
          </a>
        </li>
      <?php endforeach ?>
      <?php endif; ?>

No, what is the name of your repeater and what is the name of the sub field?

You can either do

$links = get_field('links');

or

while (have_rows('links')) {
  the_row();
  $link = get_sub_field('your_sub_field_name_here');
}
