我需要“以$ xxx购买产品A,B和C”特价,产品A,B和C必须自行提供,并且该套餐是特价优惠,可通过优惠券代码访问。
在我网站外部托管的营销页面上,我想要一个指向我网站的按钮,其中包含?add-to-cart=244,249,200
等查询字符串,以便在我的网站上,所有捆绑产品都已添加到购物车中(而不是逐一添加它们听起来令人无法接受的单调乏味。)
如果不可能,那么至少我想在我的网站上设置一个目标网页,只需一个按钮即可立即将所有捆绑产品添加到购物车中。
我找不到工作解决方案(这里是one example)。有什么建议吗?

经过一番研究后,我发现DsgnWrks wrote a hook就是这样做的。为了您的方便,如果博客离线,我直截了当地将他的代码复制到这个答案:
function woocommerce_maybe_add_multiple_products_to_cart( $url = false ) {
// Make sure WC is installed, and add-to-cart qauery arg exists, and contains at least one comma.
if ( ! class_exists( 'WC_Form_Handler' ) || empty( $_REQUEST['add-to-cart'] ) || false === strpos( $_REQUEST['add-to-cart'], ',' ) ) {
return;
}
// Remove WooCommerce's hook, as it's useless (doesn't handle multiple products).
remove_action( 'wp_loaded', array( 'WC_Form_Handler', 'add_to_cart_action' ), 20 );
$product_ids = explode( ',', $_REQUEST['add-to-cart'] );
$count = count( $product_ids );
$number = 0;
foreach ( $product_ids as $id_and_quantity ) {
// Check for quantities defined in curie notation (<product_id>:<product_quantity>)
// https://dsgnwrks.pro/snippets/woocommerce-allow-adding-multiple-products-to-the-cart-via-the-add-to-cart-query-string/#comment-12236
$id_and_quantity = explode( ':', $id_and_quantity );
$product_id = $id_and_quantity[0];
$_REQUEST['quantity'] = ! empty( $id_and_quantity[1] ) ? absint( $id_and_quantity[1] ) : 1;
if ( ++$number === $count ) {
// Ok, final item, let's send it back to woocommerce's add_to_cart_action method for handling.
$_REQUEST['add-to-cart'] = $product_id;
return WC_Form_Handler::add_to_cart_action( $url );
}
$product_id = apply_filters( 'woocommerce_add_to_cart_product_id', absint( $product_id ) );
$was_added_to_cart = false;
$adding_to_cart = wc_get_product( $product_id );
if ( ! $adding_to_cart ) {
continue;
}
$add_to_cart_handler = apply_filters( 'woocommerce_add_to_cart_handler', $adding_to_cart->get_type(), $adding_to_cart );
// Variable product handling
if ( 'variable' === $add_to_cart_handler ) {
woo_hack_invoke_private_method( 'WC_Form_Handler', 'add_to_cart_handler_variable', $product_id );
// Grouped Products
} elseif ( 'grouped' === $add_to_cart_handler ) {
woo_hack_invoke_private_method( 'WC_Form_Handler', 'add_to_cart_handler_grouped', $product_id );
// Custom Handler
} elseif ( has_action( 'woocommerce_add_to_cart_handler_' . $add_to_cart_handler ) ){
do_action( 'woocommerce_add_to_cart_handler_' . $add_to_cart_handler, $url );
// Simple Products
} else {
woo_hack_invoke_private_method( 'WC_Form_Handler', 'add_to_cart_handler_simple', $product_id );
}
}
}
// Fire before the WC_Form_Handler::add_to_cart_action callback.
add_action( 'wp_loaded', 'woocommerce_maybe_add_multiple_products_to_cart', 15 );
/**
* Invoke class private method
*
* @since 0.1.0
*
* @param string $class_name
* @param string $methodName
*
* @return mixed
*/
function woo_hack_invoke_private_method( $class_name, $methodName ) {
if ( version_compare( phpversion(), '5.3', '<' ) ) {
throw new Exception( 'PHP version does not support ReflectionClass::setAccessible()', __LINE__ );
}
$args = func_get_args();
unset( $args[0], $args[1] );
$reflection = new ReflectionClass( $class_name );
$method = $reflection->getMethod( $methodName );
$method->setAccessible( true );
$args = array_merge( array( $class_name ), $args );
return call_user_func_array( array( $method, 'invoke' ), $args );
}
通过提供以逗号分隔的产品列表,它的工作方式与您预期的一样。它甚至适用于使用?add-to-cart=63833:2,221916:4
的数量
我当时正在寻找一个纯粹的&#39;允许将多个产品添加到购物车而无需安装插件或添加自定义操作的解决方案。但对许多人来说,上述可能是一个合适的解决方案
