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(wǎng)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(jīng)有一個 archive-product.php.

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

已經(jīng)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(chǎn)品類別存檔頁面的當前產(chǎn)品類別的格式化鏈接產(chǎn)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(jīng)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(shù)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(jīng)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(yōu)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 );
