您可以在代码中使用is\\u front\\u page（）函数。

add_action(\'woocommerce_after_shop_loop_item_title\', \'description_in_shop_loop_item\', 3 );
function description_in_shop_loop_item() {
    global $product;

    if( is_front_page())
    {
        // HERE define the number of words
        $limit = 10;

        $description = $product->get_description(); // Product description
        // or
        // $description = $product->get_short_description(); // Product short description

        // Limit the words length
        if (str_word_count($description, 0) > $limit) {
            $words = str_word_count($description, 2);
            $pos = array_keys($words);
            $excerpt = substr($description, 0, $pos[$limit]) . \'...\';
        } else {
            $excerpt = $description;
        }

        echo \'<p class="description">\'.$excerpt.\'</p>\';
    }
}

非常感谢。
