在Woocommerce 3.3中为产品简码使用自定义分类法 [英] Using a custom taxonomy for products shortcode in Woocommerce 3.3

问题描述

我目前正在为Woocommerce网站开发主页，在此页面上，目标是使3行显示来自不同品牌的产品。例;第1行将显示Apple产品，第2行将显示Samsung产品，第3行将显示HTC产品。

I'm currently developing the homepage for a Woocommerce website and on this page the goal is to have 3 rows displaying products from different brands. Example; Row 1 will display Apple Products, Row 2 will display Samsung Products and Row three will display HTC products.

我已经使用插件CPT UI创建自定义分类法'牌'。现在，我希望使用上面的示例仅显示特定品牌下列出的产品。

I've used the plugin CPT UI to create the custom taxonomy 'Brand'. Now I wish to use the example above to display only products listed under a particular brand.

查看Woocommerce简码，我看到了：

Looking into the Woocommerce Shortcodes, I saw this:

[products limit="8" columns="4" category="hoodies, tshirts" cat_operator="AND"]

是否有针对此案例品牌的自定义分类法来执行类似的操作？ IE：

Is there away to do something like this with a custom taxonomy for this case brands? I.E:

[products limit="8" columns="4" brand="apple" cat_operator="AND"]

任何朝着正确方向提供帮助或推动的人都将受到赞赏！

Any assistance or nudges in the right direction are much appreciated!

推荐答案

可以将Woocommerce [产品] 短代码扩展为处理任何自定义分类法，例如 品牌 ，并带有某种技巧。

It's possible to extend Woocommerce [products] shortcode to To handle any custom taxonomy like "brand" with some kind of trick.

代码：

add_filter( 'woocommerce_shortcode_products_query', 'extend_products_shortcode_to_brand', 10, 3 );
function extend_products_shortcode_to_brand( $query_args, $atts, $loop_name ){
    if ( ! empty($atts['class']) && strpos($atts['class'], 'brand') !== false ) {
        global $wpdb;

        $terms = array_map( 'sanitize_title', explode( ',', $atts['class'] ) );
        array_shift( $terms );
        $terms = implode(',', $terms);
        $terms = str_replace(",", "','", $terms);

        $ids = $wpdb->get_col( "
            SELECT DISTINCT tr.object_id
            FROM {$wpdb->prefix}term_relationships as tr
            INNER JOIN {$wpdb->prefix}term_taxonomy as tt ON tr.term_taxonomy_id = tt.term_taxonomy_id
            INNER JOIN {$wpdb->prefix}terms as t ON tt.term_id = t.term_id
            WHERE tt.taxonomy LIKE 'brand' AND t.slug IN ('$terms')
        " );

        if ( ! empty( $ids ) ) {
            if ( 1 === count( $ids ) ) {
                $query_args['p'] = $ids[0];
            } else {
                $query_args['post__in'] = $ids;
            }
        }
    }
    return $query_args;
}

代码进入活动子主题（或活动主题）的function.php文件）。经过测试和工作。

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

使用情况

我们将在此处使用类简码参数：

We will use the class shortcode argument here:

1）一个品牌-显示 Apple品牌的产品：

1) One Brand - Displaying products from "Apple" brand:

[products limit="8" columns="4" class="brand,Apple"]

2）多个品牌-显示 Apple的产品和三星品牌：

2) multiple Brands - Displaying products from "Apple" and "Samsung" brands:

[products limit="8" columns="4" class="brand,Apple,Samsung"]

所以类品牌 是强制性的，必须是第一个。每个词都用逗号分隔。

So the class "brand" is mandatory and needs to be the first one. Each term is coma separated.
