推荐答案

这可以通过挂在 woocommerce_products_widget_query_args 过滤器钩子中的自定义函数来完成.您必须在其中的数组中设置您的产品类别(或者您的产品类别，如果有多个).

This can be done with a custom function hooked in woocommerce_products_widget_query_args filter hook. You will have to set inside it, in the array, your product category (or your product categories if more than one).

代码如下:

add_filter( 'woocommerce_products_widget_query_args', function( $query_args ){
    // Set HERE your product category slugs 
    $categories = array( 'music', 'posters' );

    $query_args['tax_query'] = array( array(
        'taxonomy' => 'product_cat',
        'field'    => 'slug',
        'terms'    => $categories,
    ));

    return $query_args;
}, 10, 1 );

代码位于活动子主题(或主题)的 function.php 文件或任何插件文件中.

Code goes in function.php file of your active child theme (or theme) or also in any plugin file.
