Woocommerce根據客戶在產品頁面輸入的金額計算金額

Question

在產品頁面中獲取客戶輸入的字數。計算產品附加固定金額的金額爲每500字以上額外10美元。

例如：530 正常價格+附加價格：$ 180 + $ 10 總計：$ 190

詞數：1040 普通1.字數價格+附加價格：180 $ + 20 $ 總計：200 $

此過程爲創建動態輸入表格客戶計算金額的價格和總金額。

`$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; 
}` 

Answer 1

我安裝了WC Fields Factory插件，然後我使用鍵從一個字段獲得了值。因爲我寫了一個函數，並且我忽略了價格的價值。

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);
