我在将多个商品添加到购物车时遇到问题。我已将此代码用于“全部添加到购物车”按钮:How does copy work and why is it so much faster than insert?
问题是我需要在URL上添加&attribute_size = 1,其中值1是分配给产品的属性值。
这是一个添加多个带有数量的ID的函数,该函数包含在functions.php中。
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 );

产品页面上的代码:
<?php
$product_ids = '111:2,100:3';
$attributeData = '20,10';
?>
<a href="http://localhost/product-page/?add-to-cart=<?php echo $product_ids ?>&attribute_size=<?php echo $attributeData ?>">KÖP</a>
