title: Advanced custom fields orderby radio button value
body: <p>Is there a smart way to order an array by the acf radio button values?
  I have a top-page page-template, and a couple of child pages with custom fields.</p>
  
  <p>In the top-page i want to display some values from the child pages:
  page title, and some values from the child pages acf fields
  And finally i want to order the array by the acf radio button values.</p>
  
  <p>The radio button values is:</p>
  
  <pre><code>one : A 
  two : B
  three : C
  four : D
  five : E
  </code></pre>
  
  <p>The field is mandatory so i don't have to test to see if there is a value.</p>
  
  <pre><code>        &lt;section id="info-box"&gt;
  
              &lt;?php
              if(function_exists( 'get_field') ){
  
              $query = new WP_Query( 'pagename=top-page' );
              $services_id = $query-&gt;queried_object-&gt;ID;
  
              wp_reset_postdata(); //* Restore original Post Data *//
  
                  $args = array(
                  'posts_per_page' =&gt; -1,
                  'post_type' =&gt; 'page',
                  'post_parent' =&gt; $services_id,
                  'orderby' =&gt; '', // radio button value //
                  'order' =&gt; 'ASC'
                  );
  
                  $services_query = new WP_Query( $args );
  
                      // The Loop
                      if ( $services_query-&gt;have_posts() ) {
  
                          echo '&lt;ul class="info-box-list"&gt;';
                              while ( $services_query-&gt;have_posts() ) {
                              $services_query-&gt;the_post();
  
                              echo '&lt;li class="list-item"&gt;'; 
  
                                  echo '&lt;div class="list-item-box"&gt;';
  
                                  echo '&lt;a href="' . get_permalink() . '" figure class="link-box-image"&gt;';
                                  the_field('image');
                                  echo '&lt;/figure&gt;';
                                  echo '&lt;/a&gt;';
  
                                  echo get_the_title();
                                  the_field( 'sub-title' );
  
                                  echo '&lt;/div&gt;';
                              echo '&lt;/li&gt;';
                              }
                          echo '&lt;/ul&gt;';
                      }
  
              /* Restore original Post Data */
              wp_reset_postdata();
              }
          ?&gt;  
         &lt;/section&gt;

  <p>Right now I'm kinda just dumping the fields onto the top-page until i can figure out if there is a smart way to order the list by the radio button value, the acf documentation is not that good on the radio buttons functionality. </p>
