[英]Get Category name from Post ID
Is it possible to get the category name of a category given the Post ID, the following code works to get the Category Id, but how can I get the name?是否可以根据帖子 ID 获取类别的类别名称,以下代码可用于获取类别 ID,但如何获取名称?
<?php $post_categories = wp_get_post_categories( 4 ); echo $post_categories[0]?>
Thank!谢谢!
here you go get_the_category( $post->ID );
给你
get_the_category( $post->ID );
will return the array of categories of that post you need to loop through the array将返回您需要遍历数组的该帖子的类别数组
$category_detail=get_the_category('4');//$post->ID
foreach($category_detail as $cd){
echo $cd->cat_name;
}
echo '<p>'. get_the_category( $id )[0]->name .'</p>';
是您可能正在寻找的。
doesn't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
wp_get_post_categories()
的第二个参数,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()
函数。
$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="" />';
}
}
?>
您可以通过简单地使用以下命令传递帖子 ID 来在一行中回显类别名称:
echo wp_get_post_terms(get_the_ID(), 'category')[0]->name;
按帖子 id 列出的第一个类别名称
$first_category = wp_get_post_terms( get_the_ID(), 'category' )[0]->name;
