Pass $page_id to new WP_Query

Question

Probably pretty simple and more PHP-related than pure WP, but how would one pass the $page_id generated in the first code snip into the new WP_Query () in the second code snip?

What I need to do - in a page template - is dynamically get the current page ID and pass that to the new WP_Query in order to display content for that current page. This is for a page template that will display different content according to the page_id, somewhat opposite of what a page template usually does with the loop.

I don't need pagination or anything else; the new queries will display small amounts of content in a jQuery UI tab structure.

Global wp_query to get current page ID (and echo it for testing purposes):

<?php global
$wp_query;
$page_id = $wp_query->get_queried_object_id();
echo $page_id; ?>

Standard new WP_Query for the content:

<?php $my_query = new WP_Query( **need $page_ID here** ); ?>
<?php while ($my_query->have_posts()) : $my_query->the_post(); ?>
<?php the_content(); ?>
<?php endwhile; ?>

Answer 1

If you're on the same page and you just need to display the same page's content again, you can just call the_content multiple times.

To answer your question, however:

You'll use the page_id argument for WP_Query (you could also probably use p). You can even remove your global $wp_query and the like.

<?php
$new_query = new WP_Query(array(
   'page_id' => get_queried_object_id()
));

Answer 2

You don't need first snippet. Just use get_the_ID() on second snippet.

<?php $my_query = new WP_Query( ** use get_the_ID() here ** ); ?>
<?php while ($my_query->have_posts()) : $my_query->the_post(); ?>
<?php the_content(); ?>
<?php endwhile; ?>
