If you use the code:

 <?php
        if(isset( $_SESSION['msg']))
        {
        echo "<font class='style1'>CHECK EMAIL & PASSWORD</font>";
        }
        else {
        echo "<font class='style1'>Welcome Guest</font>";
        }
        ?>

You are only checking to see IF the session variable was set.

First and foremost:

I am unsure if your php auto starts sessions, but it would be a good idea at the top of every file that uses sessions to have:

session_start();

If it is there but not shown, that's fine.

I would also use if (empty($SESSION .. or if (strlen($SESSION['msg']) >= 1) { .

I may be able to help a little more if you explain what is not working, i.e.

What is the expected result?
What is the current result?

lakshmiyb

The result i need is

when login values are correct it will enter into the main page,
or when their is an error in login i.e, invalid email id or password it must display in the top of the form where i placed the php code in login form

thanku for the reply

lakshmiyb

i am getting the result as

cheku userand password is displayed when i open the login page
and no change when the id is wrong but it is working for directing the page to main page when login is correct.
