Check if subfield in row is empty, and keep last item?

Hello!

I have a question regarding repeater fields.

So I have a repeater with 2 subfields — Featured Image and Additional Image.

Let’s say in the 1st row, I have both subfields filled in. But in the 2nd row, only Additional Image is filled in.

Screenshot for reference: https://imgur.com/a/gkxVmnJ

By leaving the Featured Image subfield blank in the 2nd row, I lose it completely in the front-end. I’m looking to be able to check if a subfield is empty, and if it is, then keep the last item.

Currently my php is set up like this:

<?php if(have_rows(‘large_image_layout’)) { ?>
   <?php while(have_rows(‘large_image_layout’)) {
   the_row();
   $featured_image = get_sub_field(‘featured_image’);
  ?>
 <?php } ?>
 <?php } ?>
 <div class=”featured-image” style=”background-image:url(<?php echo $featured_image; ?>);”> </div>

I hope that makes sense. Looking forward to your thoughts and responses!

Thanks so much!

This is an example or how to keep previous row values if the current row values are empty.

if (have_rows('repeater')) {
  $field_1 = false;
  $field_2 = false;
  while (have_rows('repeater')) {
    if (get_sub_field('field_1')) {
      $field_1 = get_sub_field('field_1');
    }
    if (get_sub_field('field_1')) {
      $field_1 = get_sub_field('field_1');
    }
    // use $field_1 and $field_2
  }
}
