The problem is because of form's id attribute, it has to be unique for each row. Right now you're assigning the same id value euser for each row. For maintaining the uniqueness of id value, what you can do is, append the $row['id'] with euser for each table row. Also, you forgot to encapsulate each table row in <tr>...</tr>. So your code should be like this:

<?php
    while($row=mysqli_fetch_assoc($rResultSet)){
    ?>
        <tr>
            <td><?php echo $row['id']?></td>
            <td><?php echo $row['name']?></td>
            <td><?php echo $row['user_role']?></td>
            <td><?php echo $row['start_date']?></td>
            <td>

            <form id='euser<?php echo $row['id']?>' action='edituser.php' method='post'>
                <input type="hidden" name="id" value="<?php echo $row['id']?>">
                <input type="hidden" name="type" value="edituser">

                <a  href="javascript: document.getElementById('euser<?php echo $row['id']?>').submit();">Edit</i></a>|
            </form>
        <tr>
    <?php 
    }
?>
