Hi. I try return all checked keys and values of my checkbox function. I use this code

<div>
  <?php
  $countries = get_field_object('supported_countries', $postID);

  var_dump($countries);

 if( $countries['choices'] ): ?>
 <ul>
   <?php foreach( $countries['choices'] as $value => $label ) : ?>
      <li class="country <?php echo $value; ?>"><?php echo $label; ?></li>
        <?php endforeach; ?>
</ul>
<?php endif; ?>
</div>

But I get wrong resalt.

Can you help make this function correct? How can I get only the selected items?

The field object choices contains all of the possible choices for your field, the field value contains the choices that have been made.

$field_object = get_field_object('field_name');
$field_values = get_field('field_name');
foreach ($field_values as $value) {
  <li class="<?php 
      echo $value; ?>"><?php 
      echo $field_object['choices'][$value]; ?></li>
}
