<div id="left">
        
        <img src="images/john.png" height="600px" width="300px" />
        
    </div>
    
     <div id="right">
    
        <div id="view_box">
            <ul>
                <li><img src="images/1.png" /></li>
                <!-- <li><img src="pics/2.jpg" /></li> -->
                <!-- <li><img src="pics/3.jpg" /></li> -->
            </ul>
        </div>
        
        <div id="button">
            <ul>
                <!-- <li><button class="button" scroll_value="0">*</button></li> -- >
                <!-- <li><button class="button" scroll_value="600">*</button></li> -->
                <!-- <li><button class="button" scroll_value="1200">*</button></li> -->
            </ul>
        </div>
       
       
       
        <hr />
        
        
        <?php
        
        if (($user_level !=1 && $user_level !=2)){
            echo " 
            
            Coming Soon
            
            ";
         
            
        } else {
            
       if(isset($_POST['update']))
{
  $n_password = md5($_POST['n_password']);

  $c_password = md5($_POST['c_password']);

    if($c_password === $n_password)
  {
    
     $sql="update customers set password='$n_password' where
        username='$username'";
        
     $res=mysqli_query($con,$sql);
     
     if($res)
     {
         //Password Successfully Changed.
        echo "Password Has Been Changed";
     }
     else
     {
         //Sorry, Something went wrong, Please Try Again.
         echo "Sorry, Something went wrong, Please Try Again.";
     }
  }
  else
  {
      //Password do not Match.
     echo "Passwords do not match.";
}
}
            
    ?>
        
        <h2>Change Your Password</h2>
        
        <form action="" method="post">
            <input type="password"”" name="n_password" placeholder="Enter new username" required>
 
     <input type="password" name="c_password" placeholder="Enter confirm password" required>
     
     <input type="submit" value="Submit" name="update">
        </form>
    

        
      <?php
        } 
        ?>
        
    </div>

<?php include('styles/bottom.php'); ?>

The simple answer is probably also obvious: if you don't want to show the form under certain conditions (like after the form was submitted successfully) then don't show the form under those conditions.

There's a bunch of different ways to go about it, but the one thing they all have in common is that there's an if statement that checks whether or not you want to show the form, and if you do then it shows the form. For example,

if (/* show the form */) { ?>

(the form)

<?php }
