这是我的 php 代码..

<?php
if(isset($_POST['Save']))
{

$con = mysql_connect("localhost","root","");
if (!$con)
{
die('Could not connect: ' . mysql_error());
}

mysql_select_db("storedb", $con);
$day=$_POST['day'];
$month=$_POST['month'];
$year=$_POST['year'];
$date=$day."-".$month."-".$year;
$entry=$_POST['entry'];
foreach($_POST['product'] as $row=>$pro)
{
$folder = "image/";
if($pro!="")
{
$product=$pro;
$brand=$_POST['brand'][$row];
$model=$_POST['model'][$row];
$dprice=$_POST['dprice'][$row];
$quantity=$_POST['quantity'][$row];
$tp=$_POST['txt'][$row];
$quality=$_POST['quality'][$row];
$tmp_name = $_FILES["images"]["tmp_name"][$row];
$name = $_FILES["images"]["name"][$row];
move_uploaded_file($tmp_name, "$folder".$name);
$entry=$_POST['entry'][$row];

//$sum=$_POST['sum'][$row];
//$transport=$_POST['transport'][$row];
//$grand=$_POST['grandt'][$row];
//$image=$_POST['image'][$row];
$sql=mysql_query("INSERT INTO additem (Item_id,Product,Brand,Model,Dprice,Quantity,Tprice,Quality,image) VALUES ('','$product','$brand','$model','$dprice','$quantity','$tp','$quality','$name')");

}
}

if (mysql_query($sql,$con))
{
//die('Error: ' . mysql_error());
echo "1 record added";
}
}
?>

在 HTML 中使用表单标签单击保存按钮将所有数据插入数据库。但是由于表单标签,添加行按钮总数按钮无法工作。单击这些按钮页面将刷新。如何解决这个问题

最佳答案

将按钮类型设置为“按钮”而不是提交...

<input name="btn" type="button" id="btn" value="Sum of Total Price" />
