如何更改 Line_total、总价并将最终价格发送到 paypal？

Question

如何更改 line_total 或通过 paypal 支付的价格？我可以在结帐页面计算和更改价格。但是我去paypal的时候价格不对

我听到很多查询，他们使用这个钩子。但我不知道如何更改 line_total 或税收，无论是贝宝。 add_action('woocommerce_calculate_totals', 数组($this, 'calculate_totals'), 10, 1);

function calculate_totals($totals){
//your code
$my_new_price = 100;
????? = $my_new_price;
}

对于我的结帐页面，我有这个

add_filter( 'woocommerce_cart_item_subtotal', 'show_coupon_item_subtotal_discountt', 100, 3 );
function show_coupon_item_subtotal_discountt( $subtotal, $cart_item, $cart_item_key ){
    global $woocommerce;
    //$cartsub = wp_proce(0);
    $cartsub = 0;
    $line_subtotal = $cart_item['line_subtotal'];//0
    $line_total    = number_format(floor(($cart_item['line_total']*100))/100,2);//144.51
    if( $line_subtotal !== $line_total ) {
        $discount = 0;
        $cpn=0;
        foreach ( WC()->cart->get_coupons() as $code => $coupon_notsure ) {
            $coupon = new WC_Coupon($code);
             $discount_type = $coupon->get_discount_type(); // Get coupon discount type
            if ($discount_type=="percent"){
                $discount += $line_subtotal*($coupon->get_amount()/100);
            }
            if ($discount_type=="fixed"){
                $discount += $coupon->get_amount();
            }
            $cpn++; 
        }
        
        
        
        $subtotal_tax  = $cart_item['line_subtotal_tax'];//.20
        $total_tax     = $cart_item['line_tax'];//10.39598131
        $incl_taxes    = WC()->cart->display_prices_including_tax() && $cart_item['data']->is_taxable();

        $raw_subtotal = $incl_taxes ? $line_subtotal + $subtotal_tax : $line_subtotal;
        $raw_total    = $incl_taxes ? $line_total + $total_tax : $line_total;
        ///$subtotal     = sprintf( '<del>%s</del> <ins>%s<ins>',  wc_price($raw_subtotal), wc_price($raw_total) );
        $subtotal     = sprintf( '<ins>%s<ins>',  wc_price($raw_subtotal) );
        $cartsub1 =  (float)((float)($raw_total)+$cartsub);
        $cartsub = (floor($cartsub1*100)/100);
        $woocommerce->cart->total=($line_subtotal-$discount)+$total_tax;

$woocommerce->cart->cart_contents_total =($line_subtotal-$discount)+$total_tax;
        
        //print_r($woocommerce->cart);
        //$subtotal=$cartsub;
    }else{
        $cartsub=$line_subtotal;
    }
    $woocommerce->cart->subtotal =$cartsub;
    
    
    //$cart_item['line_subtotal']=$line_subtotal;
    return $subtotal;
}

令我沮丧的是，结账时的价格完全反映了我想要的价格。但是在paypal结账时，价格是之前使用挂钩之前的价格。

您可以使用 woocommerce_paypal_args()

add_filter('woocommerce_paypal_args', 'addition_pay');

function addition_pay($paypal_args){
        $paypal_args['amount_1'] -= 0.01;
        return $paypal_args;
}
