我们有一个程序有两个按钮（批准和拒绝）。我们的问题是当我点击按钮时，提示符上的值不会保存在数据库中。

ServiceRequest.php 

<?php
session_start();
if(!isset($_SESSION['user']) || !isset($_SESSION['lname']) || !isset($_SESSION['fname']) || !isset($_SESSION['lname']) || !isset($_SESSION['pass']) || !isset($_SESSION['assign']) || !isset($_SESSION['department']) || !isset($_SESSION['branch']) || !isset($_SESSION['province']) || !isset($_SESSION['position']))
{
    header('Location:login.php');
}
include 'config.php';
?>

      </center>
    </div><?php
      include "footer.php";
    ?> 
  </body>
</html>

以下是我使用prompt（）的方法，这只会执行SQL批准和拒绝，但提示的值不会存储到数据库中。

SQL查询：

 approveserv.php<?php
session_start();
if(!isset($_SESSION['user']) || !isset($_SESSION['lname']) || !isset($_SESSION['fname']) || !isset($_SESSION['lname']) || !isset($_SESSION['pass']) || !isset($_SESSION['assign']) || !isset($_SESSION['department']) || !isset($_SESSION['branch']) || !isset($_SESSION['province']) || !isset($_SESSION['position']))
{
    header('Location:login.php');
}
include ('dbconn.php');

$idno = $_GET["idno"];
$reqstat = $_GET["status"];
$s = ret_status_service($idno);
$user = $_SESSION['user'];
$db = site_db();

    if($reqstat=="approve"){
    $sql = "UPDATE services SET status ='APPROVED', ApprovalDateTime = CURRENT_TIMESTAMP(), ApprovedBy = '".$user."'  WHERE ser_id = ?";
    }else{
    $sql = "UPDATE services SET status ='DISAPPROVED', ApprovalDateTime = CURRENT_TIMESTAMP(), ApprovedBy = '".$user."'  WHERE ser_id = ?";
    }
$s = $db->prepare($sql);
$s->execute(array($idno));
$db = null;
echo "<script>if(prompt('Successfully ${reqstat}d request.')){document.location.href='servicereq.php?s=0'};</script>";
//    header('location:servicereq.php');
?>

答案 0 :(得分：0)

如果您关注的是如何获得提示对话框的输入并将其发送到servicereq.php。您可以参考以下代码：

//servicereq.php - to get the prompt message from approveserv.php and store it to database
if(isset($_REQUEST['prompt_msg'])){
  $prompt_msg= $_REQUEST['prompt_msg'];
  // you could continue to store it in the database
}

//approveserv.php -  to output the javascript and get the prompt message and send it to servicereq.php
echo "<script>if(prompt_msg=prompt('Successfully ".$reqstat."d action request.')){document.location.href='servicereq.php?prompt_msg='+prompt_msg+'&s=0'};</script>";

注意：我想你可以设法将提示msg存储到数据库中，所以我没有在这里编写代码。

Here是如何使用提示的另一种材料。
