Wordpress-如何在functions.php中获取当前类别名称

Question

如何在functions.php中获取页面的当前类别名称？这是为了添加基于每页类别的加载更多功能。

这就是我当前的代码

add_filter('query_vars', 'registering_custom_query_var');
function registering_custom_query_var($query_vars)
{
$query_vars[] = 'id'; // Change it to your desired name
return $query_vars;
}

function more_post_ajax() {
global $wp_query;
$ppp = (isset($_POST["ppp"])) ? $_POST["ppp"] : 1;
$page = (isset($_POST['pageNumber'])) ? $_POST['pageNumber'] : 0;
$category = get_category(get_query_var('cat')); 

header("Content-Type: text/html");

$args = array(
'post_type' => 'post',
'posts_per_page' => $ppp,
'category_name' => $category->name,
'paged' => $page,
);

$loop = new WP_Query($args);

$out = '';

if ($loop->have_posts()) : while ($loop->have_posts()) : $loop->the_post();
$out .= '<div class="article_card"><div class="article_card__thumbnail">' . get_the_post_thumbnail() . '</div><div class="article_card__content"><h3><a href="' . get_the_permalink() . '">' . get_the_title() . '</a></h3><p class="body-small">' . wp_trim_words( get_the_excerpt(), 60 ) . '</p><a a href="' . get_the_permalink() . '"> Learn more →</a></div></div>';
endwhile;
endif;
wp_reset_postdata();
die($out);
}

add_action('wp_ajax_nopriv_more_post_ajax', 'more_post_ajax');
add_action('wp_ajax_more_post_ajax', 'more_post_ajax');

你在找这样的东西吗？

<?php 
$post = get_post();
if ( $post ) {
$categories = get_the_category( $post->ID );
var_dump( $categories );
}
