What? Are you saying you have created a login form but you don't want the text in red to show? What is your current code?

You are almost there. Process the user login before you display the login form. If the query didn't return any results then set the $msg variable to your error message. In the form check that this variable exists and then echo it.

<?php
include('header.php');
include('config.php');

if (isset($_POST['submit']))
{
    $username = mysql_real_escape_string($_POST['username']);
    $password = mysql_real_escape_string($_POST['password']);

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

    if(mysql_num_rows($result))
    {
        header('location:stdrecord.php');
        exit;
        
    }
    else {
        $error = "Wrong Username Or Password";        
    }
}

?>

<table class="login" align="center">
 <tr>
      <td class="table1" > Student Information System</td>
 </tr>
</table>

<div class="table2">
    <form method="post">
        <table class="table3" align="center">
            <?php if(isset($error)): ?>
            <tr>
                <td style="color: red; font-weight: bold"><?php echo $error; ?></td> 
            </tr>
            <?php endif; ?>
            <tr>
                <td>Username</td>
                <td><input type="text" name="username"></td>
            </tr>
            <tr>
                <td>Password</td>
                <td><input type="password" name="password"></td>
            </tr>
            <tr>
                <td colspan="2" align="center"><input type="submit" name="submit" value="LogIn"></td>
            </tr>
        </table>
    </form>
</div>

<?php
include('footer.php');
?>

When using using user input in SQL queries make sure you sanitize it using mysql_real_escape_string
