[英]Get Woocommerce products by custom taxonomy term values in a WP_Query
I'm developing a plugin that will be placed in my woocommerce product sidebar. 我正在开发一个插件,该插件将放置在woocommerce产品边栏中。 I need that, given the product id/object, it will find 2 product with the same custom taxonomy I created before. 我需要给定产品ID /对象,它将找到2个具有我之前创建的自定义分类法的产品。
With this code I got the list of terms used in my product where "collane" is the custom taxonomy : 通过此代码,我获得了产品中使用的术语列表,其中“ collane”是自定义分类法 :
get_the_term_list( $product->id, 'collane', '<div style="direction:rtl;">', '</div>', '' );
The problem is that I don't know how to get the custom taxonomy id, and how to filter it by my custom taxonomy. 问题是我不知道如何获取自定义分类法ID,以及如何通过自定义分类法对其进行过滤。
I've already used WP_Query to find products in the same category with this code: 我已经使用WP_Query通过以下代码查找相同类别的产品:
$args = array(
'post_type' => 'product',
'post_status' => 'publish',
'ignore_sticky_posts' => 1,
'posts_per_page' => $atts['limit'],
'tax_query' => array(
array(
'taxonomy' => 'product_cat',
'field' => 'term_id', //This is optional, as it defaults to 'term_id'
'terms' => $cat_id,
'operator' => 'IN' // Possible values are 'IN', 'NOT IN', 'AND'.
),
array(
'taxonomy' => 'product_visibility',
'field' => 'slug',
'terms' => 'exclude-from-catalog', // Possibly 'exclude-from-search' too
'operator' => 'NOT IN'
)
)
);
How can I change my code to obtain the wanted taxonomy id/object, and then use it in my WP_Query? 如何更改代码以获得所需的分类法ID /对象,然后在WP_Query中使用它?
You should try the following WP_Query
$args
that will allow to get 2 other products from the same "collane" custom taxonomy that have the same terms than the current product. 您应该尝试使用以下WP_Query
$args
,它们将允许从相同的“ collane”自定义分类中获得另外两个产品,这些产品的条款与当前产品相同。
I am using
wp_get_post_terms()
WordPress function to get the terms IDs in a post (here "product" custom post type) from a specific custom taxonomy. 我正在使用wp_get_post_terms()
WordPress函数从特定的自定义分类法中获取帖子(此处为“产品”自定义帖子类型)中的术语ID。
The code: 编码:
$taxonomy = 'collane'; // The targeted custom taxonomy
// Get the terms IDs for the current product related to 'collane' custom taxonomy
$term_ids = wp_get_post_terms( get_the_id(), $taxonomy, array('fields' => 'ids') ); // array
$query = new WP_Query( $args = array(
'post_type' => 'product',
'post_status' => 'publish',
'ignore_sticky_posts' => 1,
'posts_per_page' => 2, // Limit: two products
'post__not_in' => array( get_the_id() ), // Excluding current product
'tax_query' => array( array(
'taxonomy' => $taxonomy,
'field' => 'term_id', // can be 'term_id', 'slug' or 'name'
'terms' => $term_ids,
), ),
);
// Test count post output
echo '<p>Posts count: ' . $query->post_count . '</p>';
// The WP_Query loop
if ( $query->have_posts() ):
while( $query->have_posts() ):
$query->the_post();
// Test output
echo '<p>' . $query->post->post_title . ' (' . $query->post->ID . ')</p>';
endwhile;
wp_reset_postdata();
endif;
