This is happening because your action is empty 这是因为您的操作为空
Update your action to this 将您的操作更新为此
action="<?php echo $_SERVER['PHP_SELF']; ?>"

Make a separate php file that will insert data to database. 制作一个单独的php文件，它将数据插入数据库。 Give this in the form action attribute. 在表单操作属性中指定此名称。
<form action="insert.php" method="post">
......
......
</form>
insert.php file insert.php文件
<?php
require './database/databaseConnection.php';
if(isset($_POST['save_button']))
{
if(($_POST['fname']&&($_POST['lname'])))
{
$first_name=$_POST['fname'];
$last_name=$_POST['lname'];
$qry="INSERT INTO user_master(first_name,last_name) values('$first_name','$last_name')";
$result= mysqli_query($qry)or die(mysql_error());
if($result){
echo 'SuccessFully saved data';
}
else{
echo 'Data Not Inserted!';
}
}
}
?>
You can use header() to redirect to your previous page if you want. 如果需要，可以使用header()重定向到上一页。 Thus not allowing the refreshing of insert.php 因此不允许刷新insert.php
header("location: your_page.php");
it will be safe if you use Prepared Statements Take a look 如果你使用预处理语句这将是安全 看一看
