如何获取functions.php中页面当前的类别名称? 这是为了根据每页的类别添加加载更多功能。
这就是我当前的代码的样子
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');
您在寻找这样的东西吗?
<?php
$post = get_post();
if ( $post ) {
$categories = get_the_category( $post->ID );
var_dump( $categories );
}
使用以下内容:
get_queried_object()
这将返回类似这样的内容:
$page = get_queried_object();
echo '<pre>' . print_r($page, 1) . '</pre>';
结果:
WP_Term Object
(
[term_id] => 279
[name] => Shirts
[slug] => shirts
[term_group] => 0
[term_taxonomy_id] => 279
[taxonomy] => product_cat
[description] =>
[parent] => 277
[count] => 54
[filter] => raw
)
从这里,您可以使用以下内容:
echo $page->name;
获取类别名称:
Shirts
