How to get a list of all recently published child pages?

Question

Can you please help me on how can I display a list <li> of newly published child pages. I've been looking on google how to use display it using the wp_list_pages(); but can't find out there. I want to display it like in the "Latest Trainings" or something like that.

Answer 1

This will get you the post data for all child pages:

$args = array(
    'post_type'         => 'page',
    'post_parent__not_in'       => array(0),                               
    'no_found_rows'     => true,
);
$child = new WP_Query($args);
var_dump(wp_list_pluck($child->posts,'post_title')); // debugging only

Then pass the IDs to wp_list_pages():

$args = array(
    'post_type'         => 'page',
    'post_parent__not_in'       => array(0),                               
    'no_found_rows'     => true,
);
$child = new WP_Query($args);
$ids = wp_list_pluck($child->posts,'ID');
$ids = implode($ids,',');
$args = array(
    'include'      => $ids,
);
wp_list_pages($args);

Or, even cleaner:

$args = array(
    'post_type'         => 'page',
    'post_parent__not_in'       => array(0),                               
    'no_found_rows'     => true,
    'fields' => 'ids'
);
$child = new WP_Query($args);
$args = array(
    'include'      => $child->posts,
);
wp_list_pages($args);

Please note that there is no error checking to that code.

I'll see if I can spot a clean way to do this with filters. Check back later.

Try using the following code to generate the child pages.

<?php
// Set up the objects needed
$my_wp_query = new WP_Query();

// Query all pages
$all_wp_pages = $my_wp_query->query(array('post_type' => 'page'));

$page_ids = get_all_page_ids();

$page_children = get_page_children( $page_ids, $all_wp_pages );

echo '<li>' . print_r( $page_children, true ) . '</li>';
?>

If you're really just looking to get a list of children with wp_list_pages(), then you should use the child_of parameter to do so. But I'm assuming you're actually want to restrict that list to a certain time frame, for this wp_list_pages(), which uses get_pages(), isn't really good equipped.

So I'm thinking you should use get_posts() - or even WP_Query directly -, where you can make use of »WP_Query: Date Parameters«. The drawback here - as a generic functionwp_list_posts() does not exist - is that you have to write the code to generate your list yourself. @s_ha_dum's answer shows how you can combine this, making the drawback almost disappear - just a little bit more code is needed.
