获取所有的“活动"消息归因于WooCommerce产品附加的分类法? [英] Get all "active" attributes taxonomies attached to products in WooCommerce?

问题描述

我想获取产品所附的所有活动"属性列表，

I want to get all "active" attributes list that attached to the products,

因此，如果属性存在，但不附加到任何产品上，则不会显示.

so if the attribute exists, but don't attach to any products don't display.

我可以将所有属性显示为下拉列表，如下所示:

I can display all attributes as dropdown like this:

$attributes =  wc_get_attribute_taxonomies();

if($attributes) {
    echo '<select name="all-attributes" id="all-attributes">';
    foreach ( $attributes as $attribute ) {
        echo '<option value="' . $attribute->attribute_name . '">' . $attribute->attribute_label . '</option>';
    }
    echo '</select>';
}

但是通过这种方式，我可以获取所有属性，即使未连接非活动属性也是如此.

But this way I'm getting all attributes, even non active attributes is not attached.

如何在WooCommerce中获得附加到产品的所有活动产品属性分类法?

How to get all active product attributes taxonomies attached to products in WooCommerce?

推荐答案

要获得所有活动产品属性分类法(至少与产品关联)，您将需要一个自定义简单sql查询，如下所示(嵌入php函数):

To get all active product attributes taxonomies (attached a least to a product) you will need a custom simple sql query as follow (embedded in a php function):

function wc_get_active_attribute_taxonomies() {
    global $wpdb;

    return $wpdb->get_results( "
        SELECT DISTINCT  wat.*, tt.taxonomy
        FROM {$wpdb->prefix}woocommerce_attribute_taxonomies wat
        INNER JOIN {$wpdb->prefix}term_taxonomy tt
            ON tt.taxonomy = CONCAT('pa_', wat.attribute_name)
        INNER JOIN {$wpdb->prefix}term_relationships tr
            ON tt.term_taxonomy_id = tr.term_taxonomy_id
        WHERE tt.count > 0
    " );
}

代码进入您的活动子主题(或活动主题)的functions.php文件中.经过测试，可以正常工作.

Code goes in functions.php file of your active child theme (or active theme). Tested and works.

用法(根据您的代码):

USAGE (based on your code):

只需替换:

$attributes = wc_get_attribute_taxonomies();

作者:

$attributes = wc_get_active_attribute_taxonomies();

注意::该查询输出另外包含分类法"参数.

Note: This query output, includes additionally the "taxonomy" argument.
