問題描述

我正在嘗試在 Woocommerce 中顯示當前類別下的子類別(不是子類別等)，例如這個網站:http://www.qs-adhesivos.es/app/productos/productos.asp?idioma=en

I'm trying to Show subcategories (not subsubcategories,etc) under current category in Woocommerce like this Web: http://www.qs-adhesivos.es/app/productos/productos.asp?idioma=en

例如，Construction 是類別，Sealants &粘合劑、防水材料、聚氨酯泡沫……屬于子類別.

For Example, Construction is the category, and Sealants & adhesives, waterproofing, plyurethane foams… are subcategories.

密封劑膠粘劑是類別，而醋酸硅酮密封膠、中性硅酮密封膠、丙烯酸密封膠…是子類別…

Sealants & Mastics is the category, and ACETIC SILICONE SEALANT, NEUTRAL SILICONE SEALANT, ACRYLIC SEALANT… are subcategories…

在我的子主題下的 woocommerce 文件夾中已經有一個 archive-product.php.

Already have an archive-product.php in a woocommerce folder under my child theme.

已經嘗試了一些代碼并且它適用，但這不是我想要的.

Already tried some code and it applies but it's not what I want.

推薦答案

以下代碼將顯示產品類別存檔頁面的當前產品類別的格式化鏈接產品子類別:

The following code will display the formatted linked product subcategories from current product category for product category archive pages:

if ( is_product_category() ) {

    $term_id  = get_queried_object_id();
    $taxonomy = 'product_cat';

    // Get subcategories of the current category
    $terms    = get_terms([
        'taxonomy'    => $taxonomy,
        'hide_empty'  => true,
        'parent'      => get_queried_object_id()
    ]);

    $output = '<ul class="subcategories-list">';

    // Loop through product subcategories WP_Term Objects
    foreach ( $terms as $term ) {
        $term_link = get_term_link( $term, $taxonomy );

        $output .= '<li class="'. $term->slug .'"><a href="'. $term_link .'">'. $term->name .'</a></li>';
    }

    echo $output . '</ul>';
}

經過測試并有效.

用法示例:

1) 您可以直接在 archive-product.php 模板文件中使用此代碼.

1) You can use this code directly in archive-product.php template file.

2) 您可以將代碼嵌入到函數中，替換最后一行 echo $output .'</ul>'; 由 return $output .'</ul>';，對于短代碼，總是返回顯示.

2) You can embed the code in a function, replacing the last line echo $output . '</ul>'; by return $output . '</ul>';, as for shortcodes, the display is always returned.

3) 您可以使用諸如 woocommerce_archive_description 之類的操作掛鉤來嵌入代碼:

3) You can embed the code using action hooks like woocommerce_archive_description:

// Displaying the subcategories after category title
add_action('woocommerce_archive_description', 'display_subcategories_list', 5 ); 
function display_subcategories_list() {
    if ( is_product_category() ) {

        $term_id  = get_queried_object_id();
        $taxonomy = 'product_cat';

        // Get subcategories of the current category
        $terms    = get_terms([
            'taxonomy'    => $taxonomy,
            'hide_empty'  => true,
            'parent'      => $term_id
        ]);

        echo '<ul class="subcategories-list">';

        // Loop through product subcategories WP_Term Objects
        foreach ( $terms as $term ) {
            $term_link = get_term_link( $term, $taxonomy );

            echo '<li class="'. $term->slug .'"><a href="'. $term_link .'">'. $term->name .'</a></li>';
        }

        echo '</ul>';
    }
}

代碼位于活動子主題(或活動主題)的 functions.php 文件中.經測試有效.

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

要在類別描述后顯示，請將鉤子優先級從 5 更改為 20 在:

To display it after the category description, change the hook priority from 5 to 20 in:

add_action('woocommerce_archive_description', 'display_subcategories_list', 5 ); 

喜歡:

add_action('woocommerce_archive_description', 'display_subcategories_list', 20 );
