Here i am having problem in sending values to another page.
this is my first program here i am having userid .
index.php
<?php

$userid=$_POST['userid'];
$password=$_POST['password'];
$_SESSION['userid']=$userid;
$_SESSION['password']=$password;
$Http_Host = $_SERVER['HTTP_HOST'];
$sqlServer =@mysql_connect('localhost','root','') or die("Unable to connect to mysql ");
$db = mysql_select_db("mssi",$sqlServer) or die("Unable to connect to Users dabase");
$result = mysql_query("select * from users where username='$userid' and password='$password'");
$users = mysql_num_rows($result);
if($users>0)
{
   $ROW = mysql_fetch_array($result,MYSQL_ASSOC);
include("index2.php");
}
else
{
include("index.php");
echo "<html><head><script type=\"text/javascript\">alert (\"Please Enter Correct Username and Password\");</script></head></html>";
}

rahha,

   To send something as simple as userid, send it as GET data. Change something like:

<a href="changepwd.php">Change Password</a> to

<a href="changepwd.php?userid=<?=$userid?>">Change Password</a>


On the changepwd.php page, you would access the userid GET fiels as $_GET['$userid'].
   When you are more comfortable with PHP, I would recommend you use some type of Model-View-Controller(MVC) design pattern. Mixing your code and html with a bunch of <? ?> tag will get messy very quickly.

Thank you Howard for your response.

I will do like this the username will be displayed in the URL.
I dont want to show my username.
Is there any other way to solve this with our MVC.
I know MVC. But i want to know the solution for this with out using MVC.

Ok. My problem was solved in other way. I am using encryption and decryption.

It sounds to me like you want to use a session.

In the page you are coming from you will need this:
```
<?
    session_start();//starts a session
    $_SESSION['userid']=$userID;//after the user has logged in
?>
```
In the page you are going to you will need this:
```
<?
    session_start();//starts a session
    $userID=$_SESSION['userID'];
?>
```
Beware though, as session_start() needs to be called before any output is sent to the browser. Have a look at the php manual for more information on sessions.
