$username=mysqli_real_escape_string($dbconfig,$_POST['username']);
$password=mysqli_real_escape_string($dbconfig,$_POST['password']);
$sql_query="SELECT id FROM user WHERE username='$username' and password='$password'";
$result=mysqli_query($dbconfig,$sql_query);
$row=mysqli_fetch_array($result,MYSQLI_ASSOC);
$count=mysqli_num_rows($result);
// If result matched $username and $password, table row must be 1 row
if($count==1)
{
$_SESSION['login_user']=$username;
header("location: home.php");
}
else
{
$error="Useri ose passwordi gabim!";
}
}
?>

header("Location: login.php");
}
else
{
$name=$_SESSION['login_user'];
?>
Welcome <?php echo $name;?>
<?php
}
?>

From what I understand, you're trying to display the user's name and not the username in the welcome message.
First of all, please see that you are not even retrieving the user's name. So, you need to fetch that along with the id.
Considering the field is "name" in your database.
You can modify your query:
$sql_query="SELECT id, name FROM user WHERE username='$username' and password='$password'"; // Add name along with id
$result = mysqli_query($dbconfig,$sql_query);
$row = mysqli_fetch_array($result,MYSQLI_ASSOC);
$count = mysqli_num_rows($result);
if($count==1) {
$_SESSION['User']['username'] = $username; // Change this
$_SESSION['User']['name'] = $row['name']; // Add this
header("location: home.php");
} else {
/* Other code */
}
Now, your display code:
<?php
session_start();
if(!isset($_SESSION['User'])) {
header("Location: login.php");
} else {
$name = $_SESSION['User']['name'];
?>
Welcome <?php echo $name;?>
<?php } ?>
Hope this helps.
