billdb.php

   require_once('conn.php');
   $billno=(\filter_input(\INPUT_POST,'billno'));
   $custno=(\filter_input(\INPUT_POST,'custno'));
   $tnumber=(\filter_input(\INPUT_POST,'tnumber'));
   $subtitle=(\filter_input(\INPUT_POST,'subtitle'));
   $quantity=(\filter_input(\INPUT_POST,'quantity'));
   $price=(\filter_input(\INPUT_POST,'price'));
   $amount=(\filter_input(\INPUT_POST,'amount'));
   $tax=(\filter_input(\INPUT_POST,'tax'));
   $total=(\filter_input(\INPUT_POST,'total'));
   $sql="insert into  billmgmt(billno,custno,tnumber,subtitle,quantity,price,amount,tax,total)values('$billno','$c ustno','$tnumber','$subtitle','$quantity','$price','$amount','$tax','$total')" or          die(mysqli_error($dbhandle));
      $res=  mysqli_query($dbhandle,$sql);
      echo "success";
     mysqli_close($dbhandle);

我已经将mysql数据库中的内容检索到html表中，从html表中我需要将值存储在billmgmt表中。但是单独使用html表的最后一行值存储，使用此代码。请帮我解决。 ........

Answer 1

使用此而不是你的。

   echo "<input type='hidden' name='subtitle'  value= '".$row['subtitle']."'>";


   echo "<input type='hidden' name='quantity'  value= '".$row['quantity']."'>";

和其他输入一样，只需改变它们。

Answer 2

首先，您需要通过在其名称旁边添加[]来对阵列进行HTML输入：

echo "<input type='hidden' name='subtitle[]'  value= '{$row['subtitle']}'>";
                                        #^here

对于您在表单中重复多次的所有输入，

。

然后在你的PHP中，你需要遍历它们：

$post = $_POST; //single values $billno=mysqli_real_escape_string($dbhandle,$post['billno']); $custno=mysqli_real_escape_string($dbhandle,$post['custno']); $tnumber=mysqli_real_escape_string($dbhandle,$post['tnumber']); //multiple values go in loop foreach($post['subtitle'] as $key=>$val) { $subtitle=$val; $quantity=mysqli_real_escape_string($dbhandle,$post['quantity'][$key]); $price=mysqli_real_escape_string($dbhandle,$post['price'][$key]); $amount=mysqli_real_escape_string($dbhandle,$post['amount'][$key]); $tax=mysqli_real_escape_string($dbhandle,$post['tax'][$key]); $total=mysqli_real_escape_string($dbhandle,$post['total'][$key]); //insert statement combined with single and multiple values $sql="insert into billmgmt(billno,custno,tnumber,subtitle,quantity,price,amount,tax,total)values('$billno','$custno','$tnumber','$subtitle','$quantity','$price','$amount','$tax','$total')" or die(mysqli_error($dbhandle)); //added this line so you can know what's being entered, comment later echo $sql; $res= mysqli_query($dbhandle,$sql); } echo mysqli_error($dbhandle); mysqli_close($dbhandle);

此外，花括号{}需要从此处删除，因为它是静态值：

echo "<input type='hidden' name='tax' value= '{50.0000}'>"; #remove {}

只有html表的最后一行才会插入到数据库中
