session woes

[Zeradin]

I have this code:

if ($password == $login_info['password'])
{
	echo "<strong>Login succeeded!</strong>";
	$_SESSION['username'] = $_POST['username'];
	$_SESSION['password'] = $_POST['password'];
	?><script type="text/javascript">
			setTimeout('window.location="index.php?p=update"', 1500)
		</script><?php
		echo '<br />
		<a href="update.php">click here to continue if you are not redirected</a><br />
		<br /><img src="images/loading.gif" alt="loading..." />';
		echo $_SESSION['username'];
}

that verifies login information and then sends it to the update page. the session is still started on the update page and the username session variable works on this page, but is lost on the update page.

 

I don't know why I'm having so much trouble today. Probably something obvious. Please advise.

Make sure you're calling session_start at the top of any page that uses sessions.

i have session_start() on the index page that loads all the other pages so every page has session start at the beginning of it.

[wildteen88]

Have you place session_start in update.php?

[Zeradin]

update.php is loaded by index so there's a session start at the beginning of index. If i tried putting a session start in update I'd get an error for headers already sent. Does this have something to do with window.location? Does that get rid of session variables?

How is index.php loading (including) the other pages? Is it using a file system path or a URL in the include statement?

[Zeradin]

<?php $page = $_GET['p']; ?>

then later...

if($page != NULL)
				{	
					include($page.'.php');
				}

[Zeradin]

It's not the window location, I took it out and I still lost the variables. It's so weird. It echos out correctly and then on the next page it immediately does not echo out.

details:

 

i have a login page that is just a form and a javascript

$(document).ready(function() {
			$("#login_form").submit(function() {
				var unameval = $("#username").val();
				var pwordval = $("#password").val();
				$.post("check_login.php", { username: unameval, password: pwordval }, 
				function(data) {
					$("#status p").html(data);
				});
				return false;
			});
		});

which loads login_check.js that makes the variables. maybe there's someway they aren't actually being read to the session because the javascript is adding it to another page? and also the post variable is in the login_check, not the login?

[Zeradin]

I think it might be because of this: $("#status p").html(data);

outputs the html of check_login but not the php variables? is there something similar that'll pass variables too?
