session_start();
require "conn.php";
require "site_details.php"; ?>

<table border=1 cellpadding=1 cellspacing=1>
<tr>
<th>Id</th>
<th>Username</th>
<th>Password</th>
<th>Email</th>
<th>Delete</th>
</tr>
<?php
$res=mysqli_query($conn,"SELECT * FROM users");
while($row=mysqli_fetch_array($res))
{
echo "<tr>";
echo "<td>"; ?> <input type="checkbox" name="num[]" class="other" value="<?php echo $row["id"]; ?>" /> <?php echo "</td>";
echo "<td>"; echo $row["ids"]; echo "</td>";
echo "<td>"; echo $row["usernames"]; echo "</td>";
echo "<td>"; echo $row["passwords"]; echo "</td>";
echo "<td>"; echo $row["emails"]; echo "</td>";
echo "</tr>";
}
?>
</table>
<input type="submit" name="submit" value="delete selected">
</form>
<?php
if(isset($_POST["submit"]))
{
$box=$_POST['num'];
while (list ($key,$val) = @each ($box))
{
mysqli_query($conn,"DELETE FROM users WHERE id='$val'");
}
?>
<script type="text/javascript">
