The official Wordpress documentation can be found here.

Can WP-Query be added to a WP child theme?

I think I’m missing something obvious here!
I’m creating my first child theme based on the WordPress TwentyTwentyOne theme. I want to display posts from a particular category (e.g. ‘news’) on my home page. I created a specific page template "page-home.php", a copy of "page-php" from the parent theme, but with the following code added:

$args = array(
   'category_name' => 'news',
   'posts_per_page' => 3
);
$my_query = new WP_Query( $args );
if ( $my_query->have_posts() ) {
   while ( $my_query->have_posts() ) {
      $my_query->the_post();     
   }
}
wp_reset_postdata();

This does not work. The Eclipse IDE shows an error on the "new WP_Query()": "WP_Query cannot be resolved to a type", which is understandable, as the project does not include the wp-include directory. However, I’d expected the WordPress environment to have added this, which doesn’t seem to be the case.

I then added the following, rather convoluted code

$filename = $_SERVER["SCRIPT_FILENAME"];
$dir = substr($filename,0, strrpos($filename,"/"));
$incPath = $dir."/wp-includes";
$incPath = str_replace("/", DIRECTORY_SEPARATOR, $incPath);
set_include_path(get_include_path() . PATH_SEPARATOR . $incPath);
require_once 'class-wp-query.php';

This does not help either.

I get the feeling that there’s something obvious I’m missing, it shouldn’t be so complicated.

I’m running WordPress 5.7 on Windows 10.0.19041 with Apache 2.4 and PHP 7.4.

    I've added the line

    echo '<li>' . get_the_title() . '</li>';

    as suggested by Aleksandr, and the page now outputs the required titles.

    It works just fine for me:

    <?php
$args = array(
    'posts_per_page' => 3,
);
$the_query = new WP_Query($args);

if ($the_query->have_posts()) {
    echo '<ul>';
    while ($the_query->have_posts()) {
        $the_query->the_post();
        echo '<li>' . get_the_title() . '</li>';
    }
    echo '</ul>';
} else {
    // no posts found
}

wp_reset_postdata();
