OK when a user logs into my site, it says welcome there username.All of a sudden it stopped working, it says it the first page they view but if they click on a link then it goes away, it has all the other member stuff, here is the code:

<font color='white'><?phpsession_start();if ($_POST['login']) {if (isset($_POST['username']) and isset($_POST['password'])) {  $connect = mysql_connect('____', '_____', '_______') or die('Couldn\'t connect!');  mysql_select_db('__________') or die('Couldn\'t find db');  $username = mysql_real_escape_string($_POST['username']);  $password = md5($_POST['password']);  $query = mysql_query("SELECT * FROM ___ WHERE username = '$username' AND password = '$password'");  $row = mysql_fetch_assoc($query); {  $activated = $row['activated'];}  if ($activated=='0')  {	 die("Your account is not yet activated. Please check your email.");	 exit();}    if (mysql_num_rows($query) == 1) {	echo 'Welcome ' .$row["username"] .'.';	$_SESSION['username']=$username;  } else echo 'Incorrect username/password!';} else die('User/pass not POSTed!');}?></font>

Ok here is the page that is including the login file:

<?php include ('login.php'); if (empty($_SESSION['username'])){ ?><form method='POST'><span style='color: white;'>Username</span><br /><input type='text' style='border: none;' name='username'><br /><span style='color: white;'>Password</span><br /><input type='password' style='border: none;' name='password' /><br /><br /><input type='submit' name='login' style='border: none;' value='Log in' /></form><?php } else {?><br /><br /><a href='logout.php'>Log Out</a><br /><br /><a href='changepassword.php'>Change password</a><?php } ?><br /><br /><a href='register.php'>Register?</a>

Or most of it anyways.But that file is included on all the pages, the login file is at the top of this thread.Anyways when I log in it only displays the username for one page, then it goes away even if I click back or what ever.

You have to call session_start before any output. This won't work:

  <?phpsession_start();

When I log in it displays the username for one! page, then it goes away.
Add this cod to echo $_SESSION ['username']this cod its false $row["username"]Why?because this is just a POST data poccess, if you send a data to mysql you get the user name, but if you loged in, and refresh the page, this code not give you anything, because you not send data to mysql.I hope i understand this :)

Thats the login file.Here is the file that is on all pages, or most of it:

<?phpinclude ('page file.php');?><---HTML CODE HERE---><?phpinclude ('login.php'); if(empty($_SESSION['username'])) { ?><form method='POST'><span style='color: white;'>Username</span><br /><input type='text' style='border: none;' name='username'><br /><span style='color: white;'>Password</span><br /><input type='password' style='border: none;' name='password' /><br /><br /><input type='submit' name='login' style='border: none;' value='Log in' /></form><?php } else {?><br /><br /><a href='logout.php'>Log Out</a><br /><br /><a href='changepassword.php'>Change password</a><?php } ?><br /><br /><a href='register.php'>Register?</a></table>
