The code snippet below is handy when you are trying to check if the current page is a parent or a child in a WordPress theme. You can then use the conditional to output different code depending on the page depth it is

<?php

global $wp_query;
$object = $wp_query->get_queried_object();
$parent_id  = $object->post_parent;
$depth = 0;
while ($parent_id > 0) {
       $page = get_page($parent_id);
       $parent_id = $page->post_parent;
       $depth++;
}
 


?>

<?php if ( $depth == 0  ) {
    echo 'page level 0';

}  elseif ( $depth == 1 ) {
    echo 'page level 1';
} else {
    echo 'something else';
}?>

<?php

// gets page depth

global $wp_query;

$object = $wp_query->get_queried_object();

$parent_id = $object->post_parent;

$depth = 0;

while ($parent_id > 0) {

$page = get_page($parent_id);

$parent_id = $page->post_parent;

$depth++;

}

// echo $depth;

<?php if ( $depth == 0 ) {

echo 'page level 0';

} elseif ( $depth == 1 ) {

echo 'page level 1';

} else {

echo 'something else';

}?>
