Hello all,

I am trying to echo a username from $_SESSION['username'];
But I keep getting many errors when I try using different methods.

When I use: "$_SESSION['username'] = $username;" I get "Undefined Index: $username"
When I use: "$_SESSION['username'];" and try to call it on another page using "$userName = $_SESSION['username'];" I just get a blank response.

Can someone please help me to use $_SESSION to do this, please?

Thanks,
Western_Corleone

May sound noobish but, have you connected to your db etc..?

Are you running on xampp?
Have you started sessions? session_start();

I've done this in both files.
Running on XAMPP Lite Portable at the minute.

XAMPP is a bitch for stuff like that, try this:

<?php
$userName = ((isset($_SESSION['username'])) ? $_SESSION['username'] : '');
 
echo $userName;
?>

<?php
 
if( isset( $_SESSION['username'] ) and isset( $_SESSION['password'] ) ) {
 
$username = mysql_real_escape_string( $_SESSION['username'] );
$password = mysql_real_escape_string( $_SESSION['password'] );
 
$query = mysql_query( "SELECT * FROM users WHERE username = '" . $username . "' AND password = '" . $password . "' LIMIT 1" );
 
if( mysql_num_rows( $query ) > 0 ) {
 
$logged = mysql_fetch_assoc( $query );
 
}
 
}
 
echo $logged['username'];
echo $logged['password'];
echo $logged['email'];
 
?>

and all over rows in the table to validate from database.

Edit:

<?php echo $logged['password']; ?>

This was an example.

Neither of the solutions worked, which is really bugging me.

Is there something that's maybe disabled?

No. it happen to me. i'll add get format:

<?php
if(isset($_GET['loggin'])
{
  //code here
}
?>

and it never giving me error on SupremeCMS or just create a class/function. either one will work

After using this, it seems I get some weird errors.

1) When I put the wrong username and or password, I get "Wrong username or password"
2) When I put the correct username and or password, I get "Notice: Undefined index: username in F:\xampp-portable\htdocs\login.php on line 14

Notice: Undefined index: password in F:\xampp-portable\htdocs\login.php on line 15
Wrong Username or Password"

You can see the error here:

Pretty weird that it only gives this error when it's correct.

Post you're full page code.

And your database.

<?php
$user = $_SESSION['username'];
 
echo ''.$user.'';
?>

 

[Ecko]

<?php
$user = $_SESSION['username'];
 
echo ''.$user.'';
?>

What's with the ''. .'' ..?

Post your full code, no one wants to try and make sense of it while looking at it on a youtube clip.

It only requires basic php knowledge to know what that means. Therefore, if you don't know what that means. You really, need to brush up on your php.

I know exactly what it means, I'm wondering why you are even using it when it is utterly useless. All you need is.

echo $user;

Your method would only be necessary if you were echoing plaintext before the variable.

Oh then you could of said that. The way you explained it before was utterly rude.

Here is the "login.php" the login page is too big to paste and I think it's un-needed:

<?php
 
$host="localhost";
$username="root";
$password="";
$db_name="site";
$tbl_name="users";
 
 
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
 
 
$myusername = $_POST['username'];
$mypassword = $_POST['password'];
 
 
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'";
$result=mysql_query($sql);
 
 
$count=mysql_num_rows($result);
 
 
if($count==1){
session_start();
$_SESSION['myusername'] = $myusername;
header("location:login_success.php");
}
else {
echo "Wrong Username or Password";
}
?>
