here you go get_the_category( $post->ID );will return the array of categories of that post you need to loop through the array
在这里，您get_the_category( $post->ID );将返回该帖子的类别数组，您需要遍历该数组
$category_detail=get_the_category('4');//$post->ID
foreach($category_detail as $cd){
echo $cd->cat_name;
}

没有
<?php get_the_category( $id ) ?>
do just that, inside the loop?
这样做，在循环内？
For outside:
对于外部：
<?php
global $post;
$categories = get_the_category($post->ID);
var_dump($categories);
?>

function wp_get_post_categories( $post_id = 0, $args = array() )
{
$post_id = (int) $post_id;
$defaults = array('fields' => 'ids');
$args = wp_parse_args( $args, $defaults );
$cats = wp_get_object_terms($post_id, 'category', $args);
return $cats;
}
Here is the second argument of function wp_get_post_categories()which you can pass the attributes of receiving data.
这是函数的第二个参数wp_get_post_categories()，您可以传递接收数据的属性。
$category_detail = get_the_category( '4',array( 'fields' => 'names' ) ); //$post->ID
foreach( $category_detail as $cd )
{
echo $cd->name;
}

Use get_the_category()function.
使用get_the_category()功能。
$post_categories = wp_get_post_categories( 4 );
$categories = get_the_category($post_categories[0]);
var_dump($categories);

<?php
// in woocommerce.php
$cat = get_queried_object();
$cat->term_id;
$cat->name;
?>
<?php
// get product cat image
if ( is_product_category() ){
$cat = get_queried_object();
$thumbnail_id = get_woocommerce_term_meta( $cat->term_id, 'thumbnail_id', true );
$image = wp_get_attachment_url( $thumbnail_id );
if ( $image ) {
echo '<img src="' . $image . '" alt="" />';
