我在woocommerce单品页面中创建了一些输入自定义字段,用户可以分别输入高度和宽度值...当产品添加到购物车时,自定义字段值也显示在购物车和结帐页面中。
示例:如果用户输入高度='15'且宽度='20',则其显示为购物车页面,如高度= 15宽度= 20
单品页面
购物车页面
现在我想要实现的是根据“高度”和“宽度”自定义字段值进行自定义价格计算:
总价=(身高/ 3 *宽度/ 30 + 3)* 1.48
最终计算的价格应更新购物车商品价格。但是我无法实现这一部分,或者我不知道如何实现它。
这是我的代码:

* @return html

$value = isset( $_POST['_satish_option'] ) ? sanitize_wp_checkbox( $_POST['_satish_option'] ) : '';

我尝试通过以下代码实现公式部分:
function woo_add_custom_general_fields_save($post_id)
{
$woocommerce_product_height = $_POST['_product_height'];
$woocommerce_product_width = $_POST['_product_width'];
$woocommerce_final_price = $_POST['_final_price'];
// calculate and save _product_area_price, _regular_price, price as Height*Width
if (!empty($woocommerce_product_height) && !empty($woocommerce_product_width)))
$woocommerce_final_price = $woocommerce_product_height * $woocommerce_product_width ;
但它不起作用......
如何根据自定义购物车数据自定义计算更改购物车商品价格?
答案 0 :(得分:2)
我完全重新审视了你的代码,删除了一些小东西,重命名了其他代码并添加了缺少的部分......
你的计算看起来很奇怪:
$total_price = ($height/3 * $width/30 + 3)*1.48;
一切正常,如果需要,您可以轻松更改计算...
代码:
// Display custom input fields in single product page
add_action( 'woocommerce_before_add_to_cart_button', 'add_product_custom_fields', 20 );
function add_product_custom_fields(){
$domain = 'woocommerce';
$value = isset( $_POST['height_option'] ) ? sanitize_key( $_POST['height_option'] ) : '';
printf( '<label>%s</label><input name="height_option" value="%s" type="number"/><br>', __( 'Height', $domain ), esc_attr( $value ) );
$value = isset( $_POST['width_option'] ) ? sanitize_key( $_POST['width_option'] ) : '';
printf( '<label>%s</label><input name="width_option" value="%s" type="number"/><br>', __( 'Width', $domain ), esc_attr( $value ) );
}
// Add custom fields data to cart items and make calculation price
add_filter( 'woocommerce_add_cart_item_data', 'custom_add_cart_item_data', 20, 2 );
function custom_add_cart_item_data( $cart_item, $product_id ){
if( isset( $_POST['height_option'] ) )
$cart_item['custom_data']['height'] = sanitize_key( $_POST['height_option'] );
if( isset( $_POST['width_option'] ) )
$cart_item['custom_data']['width'] = sanitize_key( $_POST['width_option'] );
// Make calculation and save calculated price
if( isset( $_POST['height_option'] ) && isset( $_POST['width_option'] ) ){
$height = (int) sanitize_key( $_POST['height_option'] );
$width = (int) sanitize_key( $_POST['width_option'] );
if( $width > 0 && $height > 0 ){
$total_price = ( ( $height / 3 ) * ( $width / 30 ) + 3 ) * 1.48; // <== The calculation
$cart_item['custom_data']['price'] = round($total_price, 2); // Save the price in the custom data
}
}
return $cart_item;
}
// Display custom data in cart and checkout pages
add_filter( 'woocommerce_get_item_data', 'display_custom_cart_item_data', 10, 2 );
function display_custom_cart_item_data( $cart_data, $cart_item ) {
$domain = 'woocommerce';

$cart_data[] = array(

);
}
return $cart_data;
}
// Set the new calculated price replacing cart item price
add_action( 'woocommerce_before_calculate_totals', 'set_cart_item_calculated_price', 20, 1 );
function set_cart_item_calculated_price( $cart ) {
if ( is_admin() && ! defined( 'DOING_AJAX' ) )
return;
if ( did_action( 'woocommerce_before_calculate_totals' ) >= 2 )
return;
// Loop through cart items
foreach ( $cart->get_cart() as $cart_item ){
if( ! isset( $cart_item['custom_data']['price'] ) ){
continue;
}
if( $cart_item['custom_data']['price'] > 0 ){
// Set the calculated item price (if there is one)
$cart_item['data']->set_price( (float) $cart_item['custom_data']['price'] );
}
}
}
// Get cart item custom data and update order item meta and display in orders and emails
add_action( 'woocommerce_checkout_create_order_line_item', 'save_order_item_custom_meta_data', 10, 2 );

}
