<div id="po2" style="Margin:10% ">
<h1>Contacts</h1>
<?php
$sql = "SELECT * FROM `contacts`";
$query = mysqli_query($conn, $sql);
echo '<table class="data-table">';
echo'<thead>';
echo'<tr>';
echo '<th>Forename</th>';
echo '<th>Surname</th>';
echo '<th>Other</th>';
echo'</tr>';
echo '</thead>';
echo '<tbody>';
while ($row = mysqli_fetch_array($query))
{
echo '<tr>';
echo '<td>'.$row['Forename'].'</td>';
echo '<td>'.$row['Surname'].'</td>';
echo $var==$row['Forename']("<td><a href='View.php?ID= " . urlencode($var) ."'>
<button type='button'>link</button>
</a></td>");
echo '</tr>';
}
echo'</tbody>';
echo '</table>';

</div>

Answer 1

You are using a comparison of $var and the $row. Try setting $var to the $row each loop iteration.
echo '<thead>';
echo '<tr>';
echo '<th>Forename</th>';
echo '<th>Surname</th>';
echo '<th>Other</th>';
echo '</tr>';
echo '</thead>';
echo '<tbody>';
while ($row = mysqli_fetch_array($query))
{
$var = $row['Forename'];
echo '<tr>';
echo '<td>' . $var . '</td>';
echo '<td>' . $row['Surname'] . '</td>';
echo "<td><a href='View.php?ID=" . urlencode($var) . "'><button type='button'>link</button></a></td>";
echo '</tr>';
}
echo '</tbody>';
