Hello,
I want to display all unique values ​​of a “photographer” field of each media in the gallery.
Without repeating the same value if it already exists.
Example of photographer present in the select “photographer” field of ACF in the gallery:
Photographer 1
Photographer 2
Photographer 3.
I want to display:
Photographer 1
Photographer 2
Photographer 3.
and not the same value repeated.

Thanks a lot for the help.

here is my code:

  <div class="photographe">
      
    <?php $images = get_field('gallery'); ?>

        <?php if ($images) : ?>
          
                <?php foreach ($images as $image) : ?>
    
    <label><input type="checkbox" checked="checked" name="colorCheckbox" value="<?php the_field('photographe', $image['ID']); ?>"> <?php the_field('photographe', $image['ID']); ?> </label>
    <?php

?>                
                <?php endforeach; ?>
        <?php endif; ?>
    </div>

            <li><?php echo $label; ?></li>
