我有一个发票表单，它会将多行发布到插入页面以插入多行。我的绊脚石是，当我使用 foreach 语句插入多个订单项目时，我还插入了每一行的发票总额。我将如何仅在我选择的列中插入的最后一行插入例如“发票总金额”。

我已经附上了我用来插入表单的代码，在提到它之前，为了清楚起见，我已经删除了对数据清理函数的调用。

<?php 
  //Lets connect to the database
   if(mysqli_connect_errno()){
       exit("Failed to connect to the database".mysqli_connect_error());}
        //We first insert the header line of the purchase invoice, then we get the insert id and switch to the details table and insert 
         //the purchased items details

       $query ="INSERT INTO acc_posting_headers (company_id,supplier_id,header_ref,header_date,header_type,posting_ref,due_date)
       values
       ('$company_id','$supplier_id','$receipt_ref','$invoice_date','$header_type','$syspost_ref','$due_date')";

        //Execute the $sql query on the server to insert the values
          if ($conn->query($query) === TRUE) {
              $last_post_header_id =  $conn->insert_id;
              $post_header_id = $last_post_header_id;

              /* We have now switched to the details table, so we got the last insert id, we have set the variable
              $post header and now insert each purchased item */

              foreach ($_POST['lst_nominal_code'] as $row=>$id){
                $nominal_code = $_POST['hidden_nominal_code'][$row];
                 $quantity  = $_POST['txt_quantity_'][$row];
                  $item_cost = $_POST['txt_item_cost'][$row];
                   $line_total = $_POST['txt_line_total'][$row];
                    $description = $_POST['txt_description'][$row];
                     $trade_creditors = 2109;
                      $invoice_gross = $_POST['txt_gross'];
                       $vat_line = $_POST['txt_line_vat_'][$row];
                        $nominal_id = $id;
                          $subtotal = $_POST['txt_subtotal'];
                           $vat_total = $_POST['txt_vat_total'];
                            $vat_control = 2200;

           $query = ("INSERT INTO acc_posting_details 
           (post_header_id,nominal_acc_no,quantity,price,line_total,line_vat,vat_total,description,subtotal,debit,credit)
            VALUES 
            ('$post_header_id','$nominal_code','$quantity','$item_cost','$line_total','$vat_line','0','$description','$subtotal','$line_total','0'),
            ('$post_header_id','$vat_control','0','0','0','$vat_total','total VAT','vat content','0','$vat_total','0'),
            ('$post_header_id','$trade_creditors','0','0','0','0','0','trade Creditors','0','0','$invoice_gross')");

             if ($conn->query($query) === TRUE) {

          Header("Location:../add_purchase_invoice.php");



           } else {
   echo 'Error: '. $conn->error;
        }
          }
           }

              $conn->close();
              ?>

                  <?php 
                   // echo "<pre>";
                   // print_r($_POST);
                   // echo "<pre>";
                   //echo "vat control".$vat_control;
                    //echo "vat total is:".$vat_total

                  ?>

解决了，一旦我仔细看了一下，通过改变插入的顺序并从“foreach”中删除，我用下面的代码实现了我想要的。感谢所有帮助。

听起来您的核心挑战是确定您何时处于 foreach 循环的最后一次迭代，以便您可以修改查询。那正确吗？

您可以使用计数器来提供帮助。这些方面的东西：

$i = 0;
$len = count($_POST['lst_nominal_code']);

foreach ($_POST['lst_nominal_code'] as $row=>$id) {
   // Assign (don't forget to sanitize!) all the POST variables
   <snip>

   if ($i == $len - 1) {
      // This is the last line! We want a different query, with $invoice_gross included
      $query = "...";
   } else {
      // This is NOT the last line, use the default query without $invoice_gross
      $query = "...";
   }

   $conn->query($query);

   $i++;
}
