problem passing variable to header("Location:

[rmelino]

Hello,

 

I've been struggling with this for the last few hours and can't seem to figure out what the problem is...

 

I want the user to be able to click on a link in an email which contains an id variable.  I want that link to bring them to their login page.  Once they login, i want that same id variable to pass over to the url that the login resolves to upon successful login.

 

The link in the email looks something like this:

 

http://www.mysite.com/login.php?id=12345

 

the php code i have on the login.php page looks like this:

 

<?php
session_start();
require("phpsqlajax_dbinfo_new.php");
$leadid = $_GET["id"];


if(isset($_POST['login']))
{
$username = trim(addslashes($_POST['username']));
$password = md5(trim($_POST['password']));


$query = mysql_query("SELECT * FROM Users WHERE username = '$username' AND password = '$password' LIMIT 1") or die(mysql_error());

$row = mysql_fetch_array($query);

// now we check if they are activated

if(mysql_num_rows($query) > 0)
{

	if($row['activated'] > 0)
	{
		$_SESSION['s_logged_n'] = 'true';
		$_SESSION['s_username'] = $username;
		$_SESSION['s_name'] = $row['name'];
		header("Location: buy.php?leadid=" . $leadid);

	} else {

 

If this was working properly, once logged in, in this example the URL should resolve to:

http://www.mysite.com/buy.php?leadid=12345

 

Instead, it just resolves to:

http://www.mysite.com/buy.php?leadid=

 

I can't figure out why it is not passing through the variable after login.

 

Please help!

how about:

 

header("Location: buy.php?leadid=$leadid");

nope, tried that and no luck...

The php code you posted is the target of your login form submission. You have got pass the ?id=12345 through the actual form somehow, either on the end of the URL or as a hidden field in the form.

Hi,

 

Thanks for the response.

 

How would i have the buy.php page read the hidden id=12345 that i pass through the login page?

When they reach the "login" page. Save  the Variable $leadid as a $_SESSION

 

like

$_SESSION['leadid'] = $_GET['id'];

When they hit their POST and your script returns the new page, pass the $_SESSION['leadid']  as

 

 

header("Location: buy.php?leadid=" . $_SESSION['leadid']);

 

 

How about that? I think it would work if I'm understanding correctly.

keldorn,

 

unfortunately that is not working either

keldorn,

Make sure you put the $_SESSION['leadid'] = $_GET['id'];  to set the sesssion cookie when they first hit the login page. So the cookie is available when the hit post. (the cookie should get sent with their post?). I think that it should work or it might be becuase of the header redirect. I've heard that header(); can mess with sessions.

 

So maby try this.

//[...]
         $_SESSION['s_logged_n'] = 'true';
         $_SESSION['s_username'] = $username;
         $_SESSION['s_name'] = $row['name']; 
         $leadid = $_SESSION['leadid'];
session_write_close();
         header("Location: buy.php?leadid=" . $leadid);
         exit;
}else{
//[...]

This works for me:

 

$leadid=$_SESSION['leadid'];
header ("location: buy.php?leadid={$leadid}");

[rmelino]

got it working!

 

i think what i was doing wrong was:

 

originally i had

 

session_start();

$_SESSION['leadid'] = $_GET['id'];

 

 

i changed to this and it works:

 

$_SESSION['leadid'] = $_GET['id'];

session_start();

 

Thanks for all your help!
