Access Forbidden Error - php

Question

I am trying to create Pagination using PHP, trying to show 5 records per page. Everything works just fine but when I click Pagination links to go to the next page it show an error message.
Access forbidden!
You don't have permission to access the requested object. It is either
read-protected or not readable by the server.
If you think this is a server error, please contact the webmaster.
Error 403
localhost Apache/2.4.25 (Win32) OpenSSL/1.0.2j PHP/5.6.30
Here is my code.
<?php
define("SPP", 5);
if(isset($_GET['groupname']) && isset($_GET['uniname'])) {
/* VARS */
$xpage = 0;
$content = null;
$totalProfile;
$totalPage = 0;
if(isset($_GET['xpage'])) { $xpage = $_GET['xpage']; }
$start = $xpage*SPP;
$end = $start+SPP;
include("protected/config.php");
include("protected/class.db.php");
include("protected/publicLang.php");
$newSearch = new DB();
$newSearch->query("SELECT username, university,bgroup, (SELECT COUNT(id) FROM donors) AS totalProfile FROM donors WHERE bgroup = :bgroup LIMIT " . $start . ", " . $end . " ");
$newSearch->exec(array(
":bgroup" => $_GET['groupname']
));
$data = $newSearch->fetch();
foreach($data as $row) {
$totalProfile = $row['totalProfile'];
$content .= '
<tr>
<td>' . $row['username'] . '</td>
<td>'.$row['university'].'</td>
<td>' . convertBloodIdPublic($row['bgroup']) . '</td>
<td><button class="btn btn-success">Contact</button></td>
</tr> ';
}
$totalPage = round($totalProfile/SPP); }
?>
<div class="container records">
<table>
<tr>
<th>--</th>
<th>--</th>
<th>--</th>
<th>--</th>
</tr>
<?php echo $content ?>
</table>
<ul class="pagination">
<?php
for($i=1; $i<=$totalPage; $i++) {
echo '<li>' . $i . '</li>';}
?>
</ul>

403 indicates you are no longer authorized. You probably need to pass some authentication information, this is usually done by POSTING to the URL instead of GET ting it as you are now doing via a bare hyperlink/ element.
I think if you change your code to
<a href="javascript:submit_pagination($i);" >
and add a HIDDEN input element to the encompassing form and add some javascript along the lines
function submit_pagination(i){
document.forms[0].xpage.value = i;
document.forms[0].submit();
}
I think it might work. Hope it helps!
