从产品ID获取类别？

由于该问题被标记为woocommerce,因此我假设它是woocommerce wordpress插件创建的CPT产品.如果不是这种情况,则此答案不适用.

产品类别不是常规类别,它们是专门为产品创建的自定义分类法,仅被标记为"类别".

您应该浏览woocommerce文档,以找到可以为您执行此操作的功能,如果您找不到任何内容,则可以尝试其他解决方案.为此,首先您应该知道分类法的名称.当您访问后端的类别编辑屏幕时,可以从浏览器的url内部复制它.然后,您可以使用 wp_get_post_terms 来获取条款.

Since the question is tagged woocommerce, i'm assuming that it's a product CPT created by woocommerce wordpress plugin. This answer doesn't apply if that's not the case.

The products categories is not normal categories, they are a custom taxonomy created specifically for products which is just labeled as "Categories".

You should go through the woocommerce documentation to find some function that would do this for you, if you don't find anything you can try an alternative solution. For that, first you should know the name of the taxonomy. You can copy it from inside the url in your browser when you visit categories edit screen in the backend. Then you can use wp_get_post_terms to get the terms.

选项1

使用此功能获取所有product_cat的

 global $product;

$terms = get_the_terms( $product->get_id(), 'product_cat' );
 

官方文档

选项#2 如果只需要它们的ID,则可以使用以下功能获取与特定产品关联的所有product_category_id:

 global $product;

$product_cats_ids = wc_get_product_term_ids( $product->get_id(), 'product_cat' );
 

官方文档

额外

例如,如果您想打印出类别名称,则需要类别术语对象.可以使用get_term_by()进行检索.

一个例子:

 foreach( $product_cats_ids as $cat_id ) {
    $term = get_term_by( 'id', $cat_id, 'product_cat' );

    echo $term->name;
}
 

Option #1

Get all product_cat's using this function

global $product;

$terms = get_the_terms( $product->get_id(), 'product_cat' );

Offical docs

Option #2 If you only need their ids, you can get all product_category_ids associated with a specific product, using this function:

global $product;

$product_cats_ids = wc_get_product_term_ids( $product->get_id(), 'product_cat' );

Official docs

Extra

If you would like to print out - for instance - the categories names, you need the category term-object. This can be retrieved using get_term_by().

An example:

foreach( $product_cats_ids as $cat_id ) {
    $term = get_term_by( 'id', $cat_id, 'product_cat' );

    echo $term->name;
}

我回答了我自己的问题,这对我来说是有用的:

 <?php 
$term_list = wp_get_post_terms($id_product,'product_cat',array('fields'=>'ids'));
$cat_id = (int)$term_list[0];
echo get_term_link ($cat_id, 'product_cat');

?>
 

感谢Mridul Aggarwal的帮助

I answered my own question, this work for me :

<?php 
$term_list = wp_get_post_terms($id_product,'product_cat',array('fields'=>'ids'));
$cat_id = (int)$term_list[0];
echo get_term_link ($cat_id, 'product_cat');

?>

Thanks Mridul Aggarwal for your help

 <?php
   $terms = get_the_terms($product->ID, 'product_cat');
       foreach ($terms as $term) {

         $product_cat = $term->name;
            echo $product_cat;
              break;
          }
   ?>
 

<?php
   $terms = get_the_terms($product->ID, 'product_cat');
       foreach ($terms as $term) {

         $product_cat = $term->name;
            echo $product_cat;
              break;
          }
   ?>
