What you need to do when your user have log in you then need to have links in the dashboard to profile page then you need to have a query string in your link

eg

<?php 
session_start(); 
include 'dpconfig.php';

if (isset($_SESSION['uid'])) 
{
      echo $_SESSION['uid'];

      echo "<a href=\"profile.php?id=".$_SESSION['uid']."&action=view\">View Profile<a/>";
      echo "<a href=\"profile.php?id=".$_SESSION['uid']."&action=edit\">Edit Profile</a>";
}else{


    // not allowed redirect
}
?>

The above code is just a basic dashboard after the user have loggedin, we display to links to profile.php with two query string parameters, namely id we will use this to identify the current user, and action, this one will help us to know what action the user is doing(viewing/editing) their profile

Then once they on any of the link, it will go to the profile.php page with url params. then we use GET method to do our proccessing

Read about Get method here

profile.php

<?php
    session_start();

  include 'dpconfig.php';

    if(isset($_GET['id']) && isset($_GET['action'])){

        if($_GET['action'] === "view"){


            // show user profile
        }


        if(isset($_GET['action']) ==="edit"):?>

        show html form with profile info to edit then process

        <?php

        endif;

    }else{

        // not allowed do something
    }




?>

Hope this will atleast point you to the correct direction.
