Make dynamic child page link menu in Wordpress

 So go to page.php and uncomment page links

In this feature we will use wp_list_pages() function to get done this. this function return all pages from wordpress.

First remove hardcoded li from menu and use function like below ->

<ul class="min-list">
      <?php wp_list_pages()  ?>
      <!-- <li class="current_page_item"><a href="#">Our History</a></li>
      <li><a href="#">Our Goals</a></li> -->
    </ul>

and save check the page.

Now we will customize with argument like below 

 <ul class="min-list">

      <?php
      if($theParent) {
         $findChildrenOf = $theParent;
      }else {
         $findChildrenOf = get_the_ID();
      }
      wp_list_pages(array(
         'title_li' => NULL,
         'child_of' => $findChildrenOf
      ))  ?>

    </ul>

and save. and check.

Now make this menu title dynamic -> 

   <h2 class="page-links__title"><a
        href="<?php echo get_the_permalink($theParent)  ?>"><?php echo get_the_title($theParent)  ?></a>
    </h2>

and save.


now i want display this page menu only have child page and not display which have no children pages so do like below ->

  <?php
  // Check if there are child pages
  $testArray = get_pages(array(
     'child_of' => get_the_ID(),
  ));
 
  if($theParent || $testArray) {  ?>
  <div class="page-links">
    <h2 class="page-links__title"><a
        href="<?php echo get_the_permalink($theParent)  ?>"><?php echo get_the_title($theParent)  ?></a>
    </h2>

    <ul class="min-list">
      <?php
      if($theParent) {
         $findChildrenOf = $theParent;
      }else {
         $findChildrenOf = get_the_ID();
      }
      wp_list_pages(array(
         'title_li' => NULL,
         'child_of' => $findChildrenOf
      ))  ?>

    </ul>
  </div>
  <?php } ?>

and save

Also if you want set order of page in menu from dashboard do this first add below line in 

  'sort_column' => 'menu_order'


 wp_list_pages(array(
         'title_li' => NULL,
         'child_of' => $findChildrenOf
      ))

and save now go to that page and change order from right side page option.

Basics Of PHP

 Introduction to PHP PHP (Hypertext Preprocessor) is a server-side scripting language designed for web development.
