Username as Greeting (Welcome, [username]

[Skippie1]

Hi,

I am terrible with PHP. I am using Dreamweaver. I have a login page where users can log in fine and then gets redirected to another page. I want to use the username of the member of my website just used to log in to create a Welcome greeting. So if the username = Stefan it must show Welcome, Stefan.

How can this be done. I am using a SQL database where all my members is in. If somebody can help me it would be great.

Are you using a session?

How are you stopping people from simply loading the page you are redirected to without going through the login page?

Do you keep something related to the user somewhere??

Hi,

Here is the PHP script I am using at the login page, as far as I know I must use $_SESSION['MM_Username'] to create a welcome greeting but I added it but it just say Welcome, (and nothing further)

The other problem is that people can access the "protected page" by just typing oin the URL.

<?php require_once('Connections/Bloembuz.php'); ?>
<?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['user'])) {
$loginUsername=$_POST['user'];
$password=$_POST['password'];
$MM_fldUserAuthorization = "";
$MM_redirectLoginSuccess = "uploadftp.php";
$MM_redirectLoginFailed = "index.html";
$MM_redirecttoReferrer = false;
mysql_select_db($database_Bloembuz, $Bloembuz);

$LoginRS__query=sprintf("SELECT Username, Password FROM Users WHERE Username=%s AND Password=%s",
GetSQLValueString($loginUsername, "text"), GetSQLValueString($password, "text"));

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

In the page where you want to display the user name, you need to start the session to, so use session_start() there before attempting to use the $_SESSION variable.

session_start();
echo "Welcome " . $_SESSION['MM_Username'];

Hi, this is working 100%. Now how do I cancel the session once the user close the page and how do I redirect people to the login page if they are trying to type in the URL.

Hi, this is working 100%. Now how do I cancel the session once the user close the page

If the user closes the browser, the session will be destroyed automatically.

how do I redirect people to the login page if they are trying to type in the URL.

Check for the existence of a session var like $_SESSION['isloggedin'] or something you set in your login page along with the Usenamer and UserGroup variables.
If it doesn't exist, then redirect back to login, via the header(location call;

...
$_SESSION['MM_Username'] = $loginUsername;
$_SESSION['MM_UserGroup'] = $loginStrGroup;	
[red]$_SESSION['isloggedin'] = true;[/red]

session_start();
if(!isset('isloggedin']))
{
header("Location:[b][COLOR=#0066aa]loginpage.php[/color][/b]");
}

Thanks for all the help so far.

I am using FTP to upload files from a webpage to my server. It is already working but I want the user that is loggin in to upload to his own directory and I want the image name changed from whatever he called it to for example "image 1".

Currently I have a "upload" directory on my server so if user "ABC" log in I want that images to be saved at "upload/ABC".

Can you help me with this one?

Take a read of the PHP online manual entry for Handling Uploaded files. There's a function called [link php.net/manual/en/function.move-uploaded-file.php]move_uploaded_file()[/url] that you can use to move them to the specified location.

[link php.net/manual/en/features.file-upload.post-method.php]Upload File Example[/url]

Simply use yuor Username session var in the path to get it to upload where you want it.

Hi,

I tried to add the path as follows but it gives me a syntax error:

$paths="httpdocs/upload/. $_SESSION['MM_Username']";

 

[vacunita]

Try:

$paths="httpdocs/upload/[red]"[/red]. $_SESSION['MM_Username'];
