[英]WordPress get_category not working in a forloop
I'm trying to display data from all of the child product categories based on a given parent product category in woocommerce. 我正在尝试根据woocommerce中给定的父产品类别显示所有子产品类别的数据。 I am able to get an array of product category IDs with the WordPress function,
get_term_children
. 我可以使用WordPress函数
get_term_children
获得一系列产品类别ID。
$category_children = get_term_children( 25, 'product_cat' );
foreach ( $category_children as $category_id ) {
echo '<br> cat ID' . $category_id;
echo '<pre>';
print_r(get_category($category_id));
echo '</pre>';
}
The issue is when I try to display that data in a loop. 问题是当我尝试循环显示该数据时。 In this case, I have two child product categories.
在这种情况下,我有两个子产品类别。 My loop will only return data for all but the last ID.
我的循环只会返回除最后一个ID之外的所有ID的数据。 Here is what I am getting.
这就是我得到的。 The odd thing is that I can see the loop is grabbing all the IDs from
$category_children
. 奇怪的是,我可以看到循环正在从
$category_children
获取所有ID。
cat ID 26
WP_Term Object
(
[term_id] => 26
[name] => Shirts
[slug] => shirts
[term_group] => 0
[term_taxonomy_id] => 26
[taxonomy] => product_cat
[description] =>
[parent] => 25
[count] => 2
[filter] => raw
[meta_value] => 0
[cat_ID] => 26
[category_count] => 2
[category_description] =>
[cat_name] => Shirts
[category_nicename] => shirts
[category_parent] => 25
)
cat ID 27
Where is the WP_Term Object for 27. Am I not using get_category
correctly or do I need to unset it or something? 27的WP_Term对象在哪里?我没有正确使用
get_category
还是需要取消设置它?
If you look at the documentation of get_category()
, you can see that it uses the function get_term()
, with the taxonomy 'category'. 如果查看
get_category()
的文档 ,您会发现它使用了功能get_term()
和分类法“ category”。
Instead of using get_category to fetch your term children, use get_term()
directly like : 与其使用get_category来获取您的学期孩子,
get_term()
直接使用get_term()
:
$category_children = get_term_children( 25, 'product_cat' );
foreach ($category_children as $category_id) {
echo '<br> cat ID' . $category_id;
echo '<pre>';
print_r(get_term($category_id, 'product_cat'));
echo '</pre>';
}
}
Also get_term($category_id)
without the taxonomy 'product_cat' works. 同样,
get_term($category_id)
不能使用分类法“ product_cat”。
