Question

让我说，我想在PHP代码中更改密码然后它将通过使用javascript进行验证。在它返回我的索引页面之前，它会在索引页面上弹出。我该怎么做？你可以建议的任何技巧？：）

<?php
  include('config2.php');
  error_reporting(E_ERROR | E_PARSE);
    if (mysqli_connect_errno()){
        echo "Failed to connect to MySQL: " . mysqli_connect_error();
    }
    $val = $_GET['val1'];
    session_start();
    $ak = $_SESSION['autokey'];

    $sql = "UPDATE tbl_user SET password = '". md5($val) ."' WHERE autokey = '$ak'";
    mysql_query($sql);

    header("location:index");
?>

提前感谢：）

您可以像这样更改代码块..

$sql = "UPDATE tbl_user SET password = '". md5($val) ."' WHERE autokey = '$ak'";
mysql_query($sql);
if(mysql_affected_rows())
{
    echo "<script>alert('Password was successfully changed !');</script>";
    echo "<script>window.location='index.php'</script>";
} else
{
    echo "<script>alert('Password was not changed');</script>";
    echo "<script>window.location='index.php'</script>";
}

正如评论所说..你正在混淆mysql_*和mysqli_*。先改变它。

Sidenote:切换到 PreparedStatements 可以更好地抵御SQL注入攻击！
