WordPress: check if a current page has children, if so display them, if not display all pages on the same level as current page
<?php
// Your functions.php content
function has_children() {
global $post;
$pages = get_pages('child_of=' . $post->ID);
return count($pages);
}
function is_top_level() {
global $post, $wpdb;
$current_page = $wpdb->get_var("SELECT post_parent FROM $wpdb->posts WHERE ID = " . $post->ID);
return $current_page;
}
// Somewhere in your template
echo '<ul>';
$base_args = array(
'hierarchical' => 0
);
if (has_children()) {
$args = array(
'child_of' => $post->ID,
'parent' => $post->ID
);
} else {
if (is_top_level()) {
$args = array(
'child_of' => $post->post_parent,
'parent' => $post->post_parent
);
} else {
$args = array(
'parent' => 0
);
}
}
$args = array_merge($base_args, $args);
$pages = get_pages($args);
foreach ($pages as $page) {
echo '<li><a href="' . get_permalink($page->ID) . '">' . $page->post_title . '</a></li>';
}
echo '</ul>';

Thanks your sharing, also developers can use that:

if ( !empty(get_pages(['child_of' => get_queried_object_id()) { // page has children(s) } ) else { // page has no children(s) }
