Question

当我们更新数据库中的记录时，它的更新完美而不会反映在数据表中。当我们刷新页面数据表更新时。我需要刷新页面数据表更新。请帮助我。

<?php
            define('DB_SERVER', 'localhost'); // Your Database host
            define('DB_USERNAME', 'root'); // Your Database user name
            define('DB_PASSWORD', 'root'); // Your Database password
            define('DB_DATABASE', 'qwer'); // Your Database Name
            $connection = mysqli_connect(DB_SERVER,DB_USERNAME,DB_PASSWORD,DB_DATABASE); // Connection
            $sql = "SELECT nickname, email ,created_date_time,real_chips FROM users ";
            $rs = mysqli_query($connection,$sql);
            $str ="";
            $data   = array();
            while ($row = mysqli_fetch_assoc($rs)) 
            {
              $str .= '<tr id="dialog-confirm">';
              $str .= '<td>'.$row["nickname"].' </td> <td>'. $row["email"].'</td><td>'. $row["created_date_time"].'</td><td>'. $row["real_chips"].'</td>';
              $str .= '</tr>';
            }

这个ajaxphp代码

<?php
require_once("configure.php");
echo $nickname = $_POST['username'];
echo $amount = $_POST['amount'];
echo $password = $_POST['password'];

echo $sql = "SELECT * FROM users WHERE nickname ='admin' and password='$password';";
$rs = mysqli_query($connection,$sql);

$numrows=mysqli_num_rows($rs);
if($numrows > 0)
{

    echo $sql = "update users set real_chips=real_chips+'$amount' where nickname='$nickname';";
    $rs = mysqli_query($connection,$sql);
}
?>

请问您能为文件命名吗？调用Chips_AddedByAdmin.php（如果它是第二个文件）后你收到了什么？

您可以重新进行研究，以便重新填充您的数据表。或者，如果第一次请求重新加载数据表

，您可以执行另一个ajax请求

祝你好运， Morony

正确更新数据库而不是数据表服务器端
