Question

我是php的新手。我正在使用DW从mySQL自动生成用户身份验证的代码。但是，即使用户名和密码正确，生成的代码也不会将我引导到下一页，而是保留在同一页面上。你能告诉我这个问题吗？

这是我的索引文件

<?php require_once('Connections/idea.php'); ?>
<?php
if (!function_exists("GetSQLValueString")) {
function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "") 
{
  if (PHP_VERSION < 6) {
    $theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;
  }

  $theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

  switch ($theType) {
    case "text":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;    
    case "long":
    case "int":
      $theValue = ($theValue != "") ? intval($theValue) : "NULL";
      break;
    case "double":
      $theValue = ($theValue != "") ? doubleval($theValue) : "NULL";
      break;
    case "date":
      $theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";
      break;
    case "defined":
      $theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;
      break;
  }
  return $theValue;
}
}
?>
<?php
// *** Validate request to login to this site.
if (!isset($_SESSION)) {
  session_start();
}

$loginFormAction = $_SERVER['PHP_SELF'];
if (isset($_GET['accesscheck'])) {
  $_SESSION['PrevUrl'] = $_GET['accesscheck'];
}

if (isset($_POST['username'])) {
  $loginUsername=$_POST['username'];
  $password=$_POST['password'];
  $MM_fldUserAuthorization = "";
  $MM_redirectLoginSuccess = "home.html";
  $MM_redirectLoginFailed = "home.html";
  $MM_redirecttoReferrer = false;
  mysql_select_db($database_idea, $idea);

  $LoginRS__query=sprintf("SELECT username, password FROM `user` WHERE username=%s AND password=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text")); 

  $LoginRS = mysql_query($LoginRS__query, $idea) or die(mysql_error());
  $loginFoundUser = mysql_num_rows($LoginRS);
  if ($loginFoundUser) {
     $loginStrGroup = "";

    if (PHP_VERSION >= 5.1) {session_regenerate_id(true);} else {session_regenerate_id();}
    //declare two session variables and assign them
    $_SESSION['MM_Username'] = $loginUsername;
    $_SESSION['MM_UserGroup'] = $loginStrGroup;       

    if (isset($_SESSION['PrevUrl']) && false) {
      $MM_redirectLoginSuccess = $_SESSION['PrevUrl'];  
    }
    header("Location: " . $MM_redirectLoginSuccess );
  }
  else {
    header("Location: ". $MM_redirectLoginFailed );
  }
}
?>

    <form ACTION="<?php echo $loginFormAction; ?>" METHOD="POST" id="login">

      <input id="password" type="password" placeholder="PASSWORD">
      <div class="submit">

      </div>
      <p><a href="#">Forgot Password ?</a></p>
    </form>
  </div>
</div>
</body>
</html>

这里是连接文件

<?php
# FileName="Connection_php_mysql.htm"
# Type="MYSQL"
# HTTP="true"
$hostname_idea = "localhost";
$database_idea = "idea";
$username_idea = "root";
$password_idea = "";
$idea = mysqli_connect($hostname_idea, $username_idea, $password_idea) or trigger_error(mysql_error(),E_USER_ERROR); 
?>

您正在重定向到两个条件的主页。

$MM_redirectLoginSuccess = "home.html";  
$MM_redirectLoginFailed = "home.html";

只需更改$MM_redirectLoginSuccess的位置即可。

如果您想在身份验证成功时重定向到admin.php页面

$MM_redirectLoginSuccess = "admin.php";

这应该可以解决问题祝你好运
