Question

我正在尝试制作一个woocommerce滑盖旋转木马。但是meta_query不起作用，默认滑块正常工作。例如，如果我改为featured=yes它没有显示我已经设置了一些特色产品的任何东西。请帮我解决这个问题。 Woo-commerce版本是3 +。

我的短代码

[product_carousel title="LATEST PRODUCTS" per_page="6" featured="no" latest="yes" best_sellers="no" on_sale="no" orderby="menu_order" order="desc"]

和我的功能是

<?php
   function product_slider_carousel($atts){

        global $wpdb, $woocommerce;

        $arg_s = shortcode_atts(
            array(
                'title'=>'Product Slider',
                'latest'=>'yes',
                'per_page'=>'12',
                'featured' => 'no',
                'sale' => 'no',
                'best_sellers'=>'no',
                'on_sale'=>'no',
                'orderby'=>'menu_order',
                'order'=>'desc',
            ), $atts, 'product_carousel' );

        //getting the values from shortcode
        $title          =   $arg_s['title'];
        $latest         =   $arg_s['latest'];

Answer 1

在特色产品的代码中，您应该使用税务查询。您可以在WC_Shortcode_Products私有函数的set_visibility_featured_query_args()源代码中轻松查看。

  QMAKE_CXXFLAGS *= -wd4100

自Woocommerce 3以来， if(isset( $featured) && $featured == 'yes' ){ $args['tax_query'][] = array( 'taxonomy' => 'product_visibility', 'terms' => 'featured', 'field' => 'name', 'operator' => 'IN', 'include_children' => false, // optional ); } 产品属性不再作为postmeta数据处理，但现在存储为 {{1}下的帖子"featured"分类，以获得更好的表现。

Answer 2

您使用旧的查询产品的方式，WooCommerce 3引入了querying products的标准方式。以下是获取所有特色产品的示例。它使用起来更容易，并且您可以编写未来的证据，因此您应该重写您所做的并将其转换为新方法。

// Get all featured products.
$args = array(
    'featured' => true,
);
$products = wc_get_products( $args );

Woocommerce meta_query不适用于特色产品
