Woocommerce 通过猫和子猫订购购物车数组

Question

嗨，我们正在尝试按主要产品类别对 Woo Cart 进行排序，并在该类别中的产品下列出。像下面这样：

车轮零件

• 辐条 12
• 轮胎的

框架

• Y帧
• X 帧
• Z框架

座位

• 座位 1
• 座位 2

我们已经设法按猫顺序显示，但它没有将它们排序到 Main Cat -> Sub Cat

我们有以下代码并尝试按 cat 和 sub cat 订购购物车数组

add_action( 'woocommerce_cart_loaded_from_session', function() {

    global $woocommerce;
    $products_in_cart = array();
    foreach ( $woocommerce->cart->cart_contents as $key => $item ) {
        $terms = wp_get_post_terms($item['data']->id, 'product_cat' );

        $products_in_cart[ $key ] = $terms[0]->name;
    }

    natsort( $products_in_cart );

    $cart_contents = array();
    foreach ( $products_in_cart as $cart_key => $product_title ) {
        $cart_contents[ $cart_key ] = $woocommerce->cart->cart_contents[ $cart_key ];

    }
    $woocommerce->cart->cart_contents = $cart_contents;

}, 100 );

任何人有任何想法吗？

Answer 1

您的代码是正确的，但您只是natsort返回 1 导致了问题。您还需要按菜单顺序对类别进行排序。请检查下面的代码是否正常工作。

add_action( 'woocommerce_cart_loaded_from_session', function() {

    global $woocommerce;
    $products_in_cart = array();
    foreach ( $woocommerce->cart->cart_contents as $key => $item ) {
        $terms = wp_get_post_terms($item['data']->id, 'product_cat' );
        $products_in_cart[ $key ] = $terms[0]->term_id;
    }
    // $categories = get_terms( 'product_cat', 'orderby=menu_order&hide_empty=1' );

    asort($products_in_cart);
    $cat_array = array();
    foreach ($products_in_cart as $key => $value) {
        $cat_array[$key] =get_term_by('id', $value, 'product_cat');
    }
    $mai_cat = [];
    $i=0;
    foreach ($cat_array as $parent_key => $parent_value) {
        if($parent_value->parent == 0)
        {
            $mai_cat[$parent_key] = $parent_value->term_id;
            foreach ($cat_array as $parent_key_sub => $parent_value_sub) {
                if($parent_value_sub->parent == $parent_value->term_id)
                {
                    $mai_cat[$parent_key_sub] = $parent_value_sub->term_id;
                }
            }   
        }
    }
    $cart_contents = array();
    foreach ( $mai_cat as $cart_key => $product_title ) {
        $cart_contents[ $cart_key ] = $woocommerce->cart->cart_contents[ $cart_key ];

    }
    $woocommerce->cart->cart_contents = $cart_contents;
}, 100 );

经过测试并且运行良好
