自動計算總金額和滯納金

Question

現在，我正在使用月度發票系統來計算滯納金和總金額，對於第一個月，滯納金是發票金額* 10％，然后總金額是發票金額+滯納金。 對於第二個月，滯納金為第一個月的總金額* 10％，則總金額為第一個月的總金額+滯納金。

圖片是我現在正在做的

我已經完成了上面的圖片，但是手動輸入了逾期的金額以得到滯納金和總金額。 從總金額中獲取逾期金額的另一種方法是嗎？ 但是我顯示總金額的方法是循環法。

if(isset($_POST['save_inv'])){
    $ddate = count($_POST['ddate']); //get total number of array element
    for($i=0;$i<$ddate;$i++) { // loop through array and assign values in variable and insert itin database
        if(($_POST['dpayment'][$i] - $_POST['dtotal'][$i]) <= 0){
            $query4 = $DBcon->query("UPDATE owner_monthlyfees SET status = '1' WHERE owner = '".$_POST['downer'][$i]."' AND unit_name = '".$_POST['dunit'][$i]."' AND total <= '0'");
        }

        if($_POST['damt_overdue'][$i] < $_POST['dinv_sum'][$i]){
            $query7 = $DBcon->query("UPDATE owner_monthlyfees SET amount_overdue = '".$_POST['damt_overdue'][$i]."' , late_payment_charges = '".$_POST['damt_overdue'][$i]."'*('".$_POST['dlatecharge'][$i]."'/100) , payment = '".$_POST['dpayment'][$i]."' , total = '".$_POST['dinv_sum'][$i]."'+'".$_POST['damt_overdue'][$i]."'+('".$_POST['damt_overdue'][$i]."'*('".$_POST['dlatecharge'][$i]."'/100))-'".$_POST['dpayment'][$i]."' WHERE owner = '".$_POST['downer'][$i]."' and unit_name = '".$_POST['dunit'][$i]."' and date = '".$_POST['ddate'][$i]."'");
        }
        elseif($_POST['damt_overdue'][$i] > 0){
            $query3 = $DBcon->query("UPDATE owner_monthlyfees SET amount_overdue = '".$_POST['damt_overdue'][$i]."' , late_payment_charges = '".$_POST['damt_overdue'][$i]."'*('".$_POST['dlatecharge'][$i]."'/100) , payment = '".$_POST['dpayment'][$i]."' , total = '".$_POST['damt_overdue'][$i]."'+('".$_POST['damt_overdue'][$i]."'*('".$_POST['dlatecharge'][$i]."'/100))-'".$_POST['dpayment'][$i]."'

        }
    }
}

我想你想要一張桌子

首先，您要將所有原始數據存儲到一個新數組中。

$results = [];
while ($row5=$query5->fetch_array()){
  $results[] = $row5;
}

現在，您可以遍歷它們並訪問Raws之前和之后

foreach ($results as $key => &$result){
  if($key == 0 ){
    // If the months is the first month
    $result['late_payment_charges'] = $result['invoice_sum']*0.1;
    $result['total'] = $result['late_payment_charges'] + $result['invoice_sum'];
    // 0.1 is 10%
  } else {
    // Getting the previous month details
    $prevMonth = $results[$key-1];
    $result['late_payment_charges'] = $prevMonth['total']*0.1;
    $result['total'] = $prevMonth['total']+$result['late_payment_charges'];
  }
}

現在，您可以遍歷$results並將其寫入html頁面

---

添加額外的隱藏輸入或將發票編號放入輸入標簽中以獲得發票參考

<td class="text-center"><input type="text" name="invoice_number[]" value="<?php echo $dinv_no; ?>"/></td>

當您將其更新到數據庫時

foreach($_POST['invoice_number'] as $key => $value){
  $dinv_sum = $_POST['dinv_sum'][$key];
  $dpayment = $_POST['dpayment'][$key];
  //   |
  //   | Other inputs getting below format
  //   |
  //   V
  // Now executing "UPDATE INTO owner_monthlyfees SET invoice_sum = $dinv_sum" , payment = "$dpayment" ,....... WHERE inv_no = "$invoice_number"

}
