}
这是 WP Admin 中的结果：
这是我想要做的：
当客户选择变体时，我想：如果变体库存数量为 0 并且选中 _ab_preorder_checkBox 复选框，我想将产品价格设置为 100。
我尝试了下面的代码，但它不起作用：/
function action_woocommerce_before_calculate_totals( $cart_object) {
$cart_items = $cart_object->cart_contents;
if ( ! empty( $cart_items ) ) {
$price = 100;
foreach ( $cart_items as $key => $value ) {
if($value['data']['_ab_preorder_checkBox']=="yes")
$value['data']->set_price( $price );
}
}
};
add_action( 'woocommerce_before_calculate_totals','action_woocommerce_before_calculate_totals',2 );
谁能帮我解决这个问题？
问候，
解决方法
由于 woocommerce 不允许购买零库存的产品，您需要为相关产品设置“允许缺货”选项。
我重新审视了你的代码（特别是你的第二个函数）。
钩子 woocommerce_before_calculate_totals 在你的情况下不方便。最好在产品上设置延期交货自定义价格。
以下将在启用复选框时设置变体上的延期交货价格，并将其显示在具有预计交货日期的相关变体上：
// Admin Variation custom fields
add_action( 'woocommerce_product_after_variable_attributes','ab_preorder_variation_fields',10,3 );
