How to list pages with custom ACF field in Wordpress?

Question

WordPress

Good day!
Using the "Advanced Custom Fields" plugin, a custom field "County" was created. All values ​​of this field (YuAO SWAO, ZAO, SZAO, SAO, SVAO, TsAO) are assigned to different pages.
Question:
How to show a list of all pages (title, image) with this field on a separate (new) page, in order to later attach a filter to it, in which, when choosing, for example, the CAO district, pages with the value of the CAO field were displayed or when choosing the CAO , pages with the value of the CAO field were displayed.

Answer 1

You will need the WP_Query() class, which allows you to create additional loops with the parameters you need. I will make the assumption that the acf-field with information about the district is called okrug.
An example of displaying all pages in ZAO:

<?php 
// Задаем параметры цикла:
$args = array(
  'numberposts'	=> -1,
  'post_type'		=> 'page',
  'meta_key'		=> 'okrug',
  'meta_value'	=> 'ЗАО'
);

// С помощью WP_Query создаем переменную, содержащую все страницы со значением ЗАО в поле округ
$the_query = new WP_Query( $args );

?>

<?php if( $the_query->have_posts() ): ?>
  <ul>
  <?php while( $the_query->have_posts() ) : $the_query->the_post(); ?>
    <li>
      <a href="<?php the_permalink(); ?>">
        <img src="<?php echo get_the_post_thumbnail_url(); ?>" />
        <?php the_title(); ?>
      </a>
    </li>
  <?php endwhile; ?>
  </ul>
<?php endif; ?>

<?php wp_reset_query();	 // Возвращаем в норму все глобальные переменные ?>
