Woocommerce根据客户在产品页面输入的金额计算金额

Question

在产品页面中获取客户输入的字数。计算产品附加固定金额的金额为每500字以上额外10美元。

例如：530 正常价格+附加价格：$ 180 + $ 10 总计：$ 190

词数：1040 普通1.字数价格+附加价格：180 $ + 20 $ 总计：200 $

此过程为创建动态输入表格客户计算金额的价格和总金额。

`$extra_amount = (int)'10'; 
$amount = (int)'180'; // how to get amount from woocommerce data 
if(isset($_POST['wordnumber'])){ // how to get this paramater form woocommerce post values 
$test =$_POST['wordnumber']; 
$original_amount = ''; 
    if($test <= (int)'500'){ 
     $original_amount = $amount; 
    } 
    elseif($test > (int)'500'){ 
     $div_amount = $test/(int)'500'; 
     $round = floor($div_amount); 
     //echo '<br/>'; 
     $total_extra = $round*$extra_amount; 
     $original_amount = $amount+$total_extra; 
    } 
    echo $original_amount; 
}`

我安装了WC Fields Factory插件，然后我使用键从一个字段获得了值。因为我写了一个函数，并且我忽略了价格的价值。

function calculate_gift_wrap_fee($cart_object) { 
/* Gift wrap price */ 
$additionalPrice = 10; 
    foreach ($cart_object->cart_contents as $key => $value) { 
      $test = $value['custom field']; 
       if($test <= 100) { 
        $quantity = floatval($value['quantity']); 
        $orgPrice = floatval($value['data']->price); 
        $value['data']->price = ($orgPrice); 
       } 
       elseif($test > 100) { 
        $div_amount = floatval($test/500); 
        $round = floor($div_amount); 
        $total_extra = floatval($round * $additionalPrice); 
        $quantity = floatval($value['quantity']); 
        $orgPrice = floatval($value['data']->price); 
        $pp = ($value['price']); 
        $total = floatval($pp + $total_extra); 
        $value['data']->price = ($orgPrice + $total); 
       }  
    }} 
add_action('woocommerce_before_calculate_totals', calculate_gift_wrap_fee', 1, 1);
