How to open a popup window if login successful

**computerfox** · May 20 '15, 10:02 PM

Hi Slaxer,

In the code block

Code:

if ($loginFoundUser) {
     $loginStrGroup = "";

You can add:

Code:

?><script>alert("Login successful!")</script><?php

Hope that helps!

how can i make a popup window appear if the login is successful and redirect to another page (for example index.php) automatically

hm, what is the point of a popup if you redirect anyways?

PS. Don’t let DreamWeaver make your PHP code, that’s always a sore sight. better use Prepared Statements if you want to be protected from SQL Injection.

Hi mate,

The code i have has been retrieved from the web. This is just a school work and i'm still a newbie at this. Any tips will be much appreciated.

Hi computerfox,

Could you write how the code should be? i tried but it hasn't been working.

Thanks to both ;)

Peace,

since you’re new, don’t start to learn the outdated and deprecated mysql extension. better use mysqli or PDO (personally I recommend PDO over MySQLi, because it’s more straightforward to use).

Any suggestion on any site or article i can look in?

**Dormilich** · May 21 '15, 10:10 AM

the linked manual pages should get you started.

**Slaxer13** · May 21 '15, 10:15 AM

Thanks for the help i will look into it.
As for the topic do you know how i can do that popup? I tried computerfox way but either i am doing wrong or something else 'cause its not working :/

Can I see your updated code?

**computerfox** · May 21 '15, 06:21 PM

Try this:

Code:

<?php require_once('Connections/Info_Registos.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;
}
}
 
mysql_select_db($database_Info_Registos, $Info_Registos);
$query_Login = "SELECT * FROM utilizador";
$Login = mysql_query($query_Login, $Info_Registos) or die(mysql_error());
$row_Login = mysql_fetch_assoc($Login);
$totalRows_Login = mysql_num_rows($Login);
?>
<?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['utilizador'])) {
  $loginUsername=$_POST['utilizador'];
  $password=$_POST['password'];
  $MM_fldUserAuthorization = "";
  $MM_redirectLoginSuccess = "index.php";
  $MM_redirectLoginFailed = "login_incorreto.php";
  $MM_redirecttoReferrer = false;
  mysql_select_db($database_Info_Registos, $Info_Registos);
 
  $LoginRS__query=sprintf("SELECT utilizador, password FROM utilizador WHERE utilizador=%s AND password=%s",
    GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text")); 
 
  $LoginRS = mysql_query($LoginRS__query, $Info_Registos) 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'];    
    }
    ?><script>alert("Login successful!");</script><?php
    header("Location: " . $MM_redirectLoginSuccess );
  }
  else {
   ?><script>alert("Login failed!");</script><?php
    header("Location: ". $MM_redirectLoginFailed );
  }
}
?>

Also, as Dorm mentioned, why do you want to add a popup for the confirmation and then redirect to another confirmation? Seems un-needed. And yeah, don't use Dreamweaver, Notepad or Notepad++ work better. Or if you're on a Unix/Linux based machine, use vim.

**Slaxer13** · May 22 '15, 10:55 AM

I will try as soon as possible and post the result. I am using dreamweaver 'cause my teacher choose it :/ I want that popup only and then redirect to my main page. The confirmation window i have will be deleted. It was created because i couldn't do the popup.

Peace,

I tried to do that but it does exactly the same thing

**computerfox** · May 22 '15, 01:15 PM

Do you have JavaScript enabled?

**Slaxer13** · May 25 '15, 09:22 AM

Sorry for the delay. How can i see that?

Did you code previously redirect prior to our changes?
I updated your switch statement as the "long" case didn't have a break.
Can you try now?
