我需要一些帮助才能在结帐页面上显示购物车中所有产品的加价销售情况,以下代码给我以下错误:
调用数组中的成员函数get_upsell_ids()…
这是我的功能:
function show_cross_sell( $limit = '-1', $columns = 4, $orderby = 'rand', $order = 'desc' ) {
global $woocommerce;
$items = WC()->cart->get_cart();
if ( ! $items ) {
echo 'nothing';
return;
}
// Handle the legacy filter which controlled posts per page etc.
$args = apply_filters(
'woocommerce_upsell_display_args',
array(
'posts_per_page' => $limit,
'orderby' => $orderby,
'order' => $order,
'columns' => $columns,
)
);
foreach($items as $product) {
wc_set_loop_prop( 'name', 'up-sells' );
wc_set_loop_prop( 'columns', apply_filters( 'woocommerce_upsells_columns', isset( $args['columns'] ) ? $args['columns'] : $columns ) );
$orderby = apply_filters( 'woocommerce_upsells_orderby', isset( $args['orderby'] ) ? $args['orderby'] : $orderby );
$order = apply_filters( 'woocommerce_upsells_order', isset( $args['order'] ) ? $args['order'] : $order );
$limit = apply_filters( 'woocommerce_upsells_total', isset( $args['posts_per_page'] ) ? $args['posts_per_page'] : $limit );
// Get visible upsells then sort them at random, then limit result set.
$upsells = wc_products_array_orderby( array_filter( array_map( 'wc_get_product', $product->get_upsell_ids() ), 'wc_products_array_filter_visible' ), $orderby, $order );
$upsells = $limit > 0 ? array_slice( $upsells, 0, $limit ) : $upsells;
wc_get_template(
'single-product/up-sells.php',
array(
'upsells' => $upsells,
// Not used now, but used in previous version of up-sells.php.
'posts_per_page' => $limit,
'orderby' => $orderby,
'columns' => $columns,
)
);
}
}

您的代码中有一些错误……以下内容将合并购物车项目中的所有加售ID(无重复),并将它们显示为唯一的加售块:
function show_items_upsells( $limit = '-1', $columns = 4, $orderby = 'rand', $order = 'desc' ) {
$cart = WC()->cart;
if ( WC()->cart->is_empty() ) {
echo 'nothing';
return;
}
$upsell_ids = $cart_item_ids = array();
// Loop through cart items
foreach( $cart->get_cart() as $cart_item ) {
// Merge all cart items upsells ids
$upsell_ids = array_merge( $upsell_ids, $cart_item['data']->get_upsell_ids() );
$cart_item_ids[] = $cart_item['product_id'];
}
// Remove cart item ids from upsells
$upsell_ids = array_diff($upsell_ids, $cart_item_ids);
$upsell_ids = array_unique($upsell_ids); // Remove duplicated Ids
// Handle the legacy filter which controlled posts per page etc.
$args = apply_filters( 'woocommerce_upsell_display_args', array(
'posts_per_page' => $limit,
'orderby' => $orderby,
'order' => $order,
'columns' => $columns,
));
wc_set_loop_prop( 'name', 'up-sells' );
wc_set_loop_prop( 'columns', apply_filters( 'woocommerce_upsells_columns', isset( $args['columns'] ) ? $args['columns'] : $columns ) );
$orderby = apply_filters( 'woocommerce_upsells_orderby', isset( $args['orderby'] ) ? $args['orderby'] : $orderby );
$_order = apply_filters( 'woocommerce_upsells_order', isset( $args['order'] ) ? $args['order'] : $order );
$limit = apply_filters( 'woocommerce_upsells_total', isset( $args['posts_per_page'] ) ? $args['posts_per_page'] : $limit );
// Get visible upsells then sort them at random, then limit result set.
$upsells = wc_products_array_orderby( array_filter( array_map( 'wc_get_product', $upsell_ids ), 'wc_products_array_filter_visible' ), $orderby, $_order );
$upsells = $limit > 0 ? array_slice( $upsells, 0, $limit ) : $upsells;
wc_get_template( 'single-product/up-sells.php', array(
'upsells' => $upsells,
// Not used now, but used in previous version of up-sells.php.
'posts_per_page' => $limit,
'orderby' => $orderby,
'columns' => $columns,
) );
}
代码进入活动子主题(或活动主题)的function.php文件。经过测试,可以正常工作。
用法: echo show_items_upsells();
