How to correct the request in wp?

Question

WordPress

<?php $posts = get_posts( [
'category' => 76967,
'orderby' => date,
'numberposts' => 6,
] );?>

There is such a request, you need to change it so that it gives out posts from categories 76967 + 2
(if both of these categories are present only), if you set 'category' => 76967.2, then we get categories with one of the parameters (76967 or 2).

Answer 1

$query = new WP_Query( [
  'orderby' => 'date',
  'posts_per_page' => 6,
  'category__and' => array( 76967, 2 ),
] );

Or you can collect tax_query , it looks clearer this way

$query = new WP_Query( [
  'orderby' => 'date',
  'posts_per_page' => 6,
  'tax_query' => [
    'relation' => 'AND',
    [
      'taxonomy' => 'category',
      'field'    => 'id',
      'terms'    => array( 76967, 2 ),
      'operator' => 'AND',
    ]
  ]
] );

request started working (it gave exactly the right entry), but empty entries appeared as in the screenshot leading nowhere

<?php if ($posts) : $counter = 0;?>
                                                <div class="district-news">
