Answer 1

s您可以嘗試更改您的查詢。在這種情況下添加查詢鍵：post_parent__in。這應該將結果限制爲具有特定父ID的所有our-trainers Post-Type。

<?php 
      $array = array(
       'post_type'  => 'our-trainers', 

       // ADD THE FOLLOWING LIKE: THE ARRAY COULD BE A LIST OF IDS OR JUST 1 ID. 
       'post_parent__in' => array("ID_OF_THE_POST_PARENT"), 

       'posts_per_page' => 30, 
       'order'   => 'ASC' 
     ); 
      $array_query = new wp_query($array); 
     while ($array_query->have_posts()) : $array_query->the_post(); 
      // THE REST OF THE CODE... 

OPTION NR 2

<?php 
      $parentIDs = array(214, 412); 
      $array  = array(
       'post_type'  => 'our-trainers', 
       'posts_per_page' => 30, 
       'order'   => 'ASC' 
     ); 
      $array_query = new wp_query($array); 
     while ($array_query->have_posts()) : $array_query->the_post(); 
      $pID   = get_the_ID(); 
      // GET THE POST OBJECT; 
      $pOBJ  = get_post($pID); 
      // CHECK IF THE PARENT ID OF THE POST IS CONTAINED IN THE LIST OF 
      // PARENT_IDS... 
      if(in_array($pOBJ->parent_id, $parentIDs)){ 
       // DISPLAY ONLY THESE POSTS... 
      } 
      // THE REST OF THE CODE...
