[英]php login doesn't redirect

问题描述

I used Dreamweaver to make a login page but it doesn't work, after hitting submit it just reloads the page, even in sucess or failure it should change to a different page. 我用Dreamweaver制作了一个登录页面，但是它不起作用，在单击“提交”后，它只是重新加载了页面，即使成功或失败，它也应该更改为另一个页面。 Anyone knows what I did wrong? 有人知道我做错了吗？ 

<?php require_once('Connections/trabalhoCD.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) {

Remove those extra php tags. 删除那些多余的php标签。 They are probably adding whitespace that us being sent before you call header 他们可能会在您致电header之前添加发送给我们的空白 

<?php require_once('Connections/trabalhoCD.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;
}
}

// 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['login'])) {
  $loginUsername=$_POST['login'];
  $password=md5($_POST['pass']);
  $MM_fldUserAuthorization = "";
  $MM_redirectLoginSuccess = "tabela1.php";
  $MM_redirectLoginFailed = "login2.php";
  $MM_redirecttoReferrer = false;
  mysql_select_db($database_trabalhoCD, $trabalhoCD);

  $LoginRS__query=sprintf("SELECT login, pass FROM utilizador WHERE login=%s AND pass=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text")); 

  $LoginRS = mysql_query($LoginRS__query, $trabalhoCD) 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 );
  }
}
?>
...

Also, you should try to organize your code in such a way that you don't need to check if a function is defined before you define it (that's a performance issue and just seems, to me, like a bad idea) 另外，您应该尝试以无需组织函数的方式来组织代码（在定义函数之前，这是一个性能问题，在我看来，这是一个坏主意）

Also, the mysql_ library is deprecated in php 5 and removed from php 7. Consider switching to mysqli or PDO which will let you use parameterized queries. 另外，在php 5中不推荐使用mysql_库，并从php 7 中将其删除。 考虑切换到mysqli或PDO，这将允许您使用参数化查询。 (pdo is the way to go, imo) （pdo是前进的方式，imo）
