在Woocommerce中,我使用自定义字段来计算产品的价格,基于此代码 - Cart item price calculation, based on the chosen “days” custom field in Woocommerce。非常感谢LoicTheAztec的帮助。
// HERE your rental days settings
function get_rental_days_options() {

'2' => __("2 Days", "woocommerce"),
'4' => __("4 Days", "woocommerce"),

add_action('woocommerce_before_add_to_cart_button', 'display_single_product_custom_fields', 5);

$options = array('' => __("Choosen period", "woocommerce")) + get_rental_days_options();

}
我没想到计算用户价格的新条件((这是最后一个)。
如果用户购买基本价格大于6,660的产品,则标准计算遵循上面显示的代码。
如果用户购买基本价格低于6,660的产品,则新价格为每天999。接下来,用户选择租赁期。如果他选择2天,那么999 * 2.如果他选择4天,那么999 * 4。
据我了解,我需要添加条件,如果base_price> 6600(以下是标准计算代码)和base_price <6600(然后根据用户选择的999 * 2或999 * 4计算)。
我需要在产品单页的基本价格旁边得出价格['new_price']的结论。
但我不太明白如何正确实现它。
我很高兴你的帮助!
更新:我放了一个没有插件的干净版Wordpress。激活了店面的主题。添加了演示数据。
在文件中,functions.php添加了代码以及您的编辑:

以下是截图:
用计算价格的小问题。
如果基本价格> 6660,它不会计算,也不会出现在购物车中。如果基本价格<6660,那么一切正常。
我需要计算并显示在购物车中的两个条件。
如果客户购买这两种产品,其中一种产品价格不合理,那就不好了((
更新2:我更新了代码。这是购物车的屏幕截图:
而不是680美元,应该是5100美元。
而不是1360美元,应该是10200美元。
17000 / 100 * 15 = 2550
2550 * 2 = 5100
2550 * 4 = 10200
如何在基本价格旁边的单个产品页面上显示新价格?
(更新/新答案)
第1步:在此代码之上:
// HERE your rental days settings
function get_rental_days_options() {
... code removed, but nothing changed here.
}
添加此代码,计算新价格 - 并根据新计算:
// Calculate new price based on rental period/days.
function calc_rental_new_price( $rental_days, $base_price ) {
$percentage = 15;
if ( $base_price > 6660 ) {
$price_rate = $rental_days * $percentage / 100;
return $base_price * $price_rate;
} else {
return 999 * $rental_days;
}
}
第2步:使用这个新的add_custom_field_data()
代码 - 为了清晰起见,它重新缩进:
function add_custom_field_data($cart_item_data, $product_id, $variation_id) {
if (isset($_POST['rental_date']) && !empty($_POST['rental_date'])) {
$cart_item_data['custom_data']['start_date'] = $_POST['rental_date'];
}
if (isset($_POST['rental_days']) && !empty($_POST['rental_days'])) {
$cart_item_data['custom_data']['rental_days'] = esc_attr($_POST['rental_days']);
$_product_id = $variation_id > 0 ? $variation_id : $product_id;
$product = wc_get_product($_product_id); // The WC_Product Object
$base_price = (float) $product->get_regular_price();
// Set base price.
$cart_item_data['custom_data']['base_price'] = $base_price;
// Set new price.
$cart_item_data['custom_data']['new_price'] = calc_rental_new_price(
$cart_item_data['custom_data']['rental_days'], $base_price
);
}
// Make each cart item unique
if (isset($cart_item_data['custom_data']['rental_days']) || isset($cart_item_data['custom_data']['start_date'])) {
$cart_item_data['custom_data']['unique_key'] = md5(microtime().rand());
}
return $cart_item_data;
}
第3步:在此代码之后:
function custom_fields_update_order_item_meta($item, $cart_item_key, $values, $order) {
... code removed, but nothing changed here.
}
添加此代码,在基本价格旁边显示单个产品页面上的新价格:
// Adds the new price next to the base price. That new price is for 1 day rental period.
add_filter( 'woocommerce_get_price_html', 'add_new_price_html', 10, 2 );
function add_new_price_html( $html, $product ) {
// Check if we're on a single Product page, the shop page, or a products archive page.
if ( ! is_product() && ! is_shop() && ! is_product_taxonomy() ) {
return $html;
}
$base_price = (float) ( 'variable' === $product->get_type() ?
$product->get_variation_regular_price() : $product->get_regular_price() );
$new_price = calc_rental_new_price( 1, $base_price );
// If it's a Variable product, appends "From " to the new price.
$text_from = ( 'variable' === $product->get_type() ) ? 'From ' : '';
return $html . ' <span class="new-price">' . $text_from . wc_price( $new_price ) . ' / day</span>';
}
$base_price
。
