Rectrict user to its own page and show their own project - php

Question

I have a login script with a admin thats redirected to his own page dashboardadmin.php.Then i have a page called dashboarduser.php. The users have its own page dashboarduser.php. When the user comes to dashboarduser.php it should only show their project. Now its showing all of the projects. I have created the omproject.php that show the project. So what i want is when user login is should come to dashboarduser.php and only show their projct.
index.php
<?php
if (isset($_GET['error'])) {
echo '<p class="error">Error!</p>';
}
?>
<form action="includes/process_login.php" method="post" name="login_form">
<label for="email"> Email:</label> <input type="email" id="email" name="email" />
<label for="password">Password: </label> <input type="password"
name="password"
id="password"/>
<input type="submit"
value="Login"
onclick="formhash(this.form, this.form.password);" />
</form>
process_login.php
<?php
include_once 'db_connect.php';
include_once 'functions.php';
sec_session_start(); // Our custom secure way of starting a PHP session.
if (isset($_POST['email'], $_POST['p'])) {
$email = $_POST['email'];
$password = $_POST['p']; // The hashed password.
if (login($email, $password, $mysqli) == true) {
// Login success
header('Location: ../dashboardadmin.php');
} else {
// Login failed
header('Location: ../index.php?error=1');
}
} else {
// The correct POST variables were not sent to this page.
echo 'Invalid Request';
}
?>

You don't have a link between your project table and your user table. You'll need to add a column in your project table which refers to the user that owns the project. Let's name that table "user_id" for now.
After login you should have the id of the user that's logged in. you can use that to get their project. Then to fetch their projects you can use the following sql query:
$sql= "SELECT pid, project_name, image, image_type FROM project WHERE user_id =" . $loggedInUserId;
