How Can I send $_POST with query string in a link - php

Question

This is php code which checks if form(on same page) is posted and gets the result depending upon $_POST array if it is posted or returns all results from data base. this also sets $total variable containing number_of_pages later used for pagination
if(!isset($_POST['search']))
{
$id = (isset($_GET['id']) ? $_GET['id'].'0' : 10);
$id = $id-10;
$query = "select SQL_CALC_FOUND_ROWS * from feedbacks order by Date desc limit $id, 10 ";
}
else if (!empty($_POST['from']))
{
$timstmp = strtotime($_POST['from']);
$dt = date("Y-m-d H:i:s", $timstmp);
$id = (isset($_GET['id']) ? $_GET['id'].'0' : 10);
$id = $id-10;
$query = "SELECT SQL_CALC_FOUND_ROWS * FROM `feedbacks` WHERE `Date` >= \"$dt\" order by Date desc limit $id, 10 ";
}
else if (!empty($_POST['name']))
{
$name = '%'.$_POST['name'].'%';
$id = (isset($_GET['id']) ? $_GET['id'].'0' : 10);
$id = $id-10;
$query = "SELECT SQL_CALC_FOUND_ROWS * FROM `feedbacks` WHERE `name` LIKE '$name' order by Date desc limit $id, 10 ";
}
$result= mysqli_query($connection, $query);
$r = mysqli_fetch_array(mysqli_query($connection, 'SELECT FOUND_ROWS()'));
$total = ceil($r['FOUND_ROWS()']/10);
$feedbacks = array();
for ($i = 0;$row= mysqli_fetch_assoc($result); $i++)
{
$feedbacks[$i] = new FeedBack($row);
}
?>
These are the html links that are automatically generated depending upon the total number of pages which is calculated depending upon results from data base
<?php
if ($total>1)
{ ?> <div class="pagging">
<?php for( $i=$total; $i>=1; $i--)
{ ?>
<div class="right">
<a id="pagination" href="index.php?id=<?php echo $i; ?>"><?php echo $i; ?></a>
</div>
<?php } ?>
</div>
<?php } ?>
</div>
<!-- Table -->
On this page I'm implementing filters. User input data in the form and press search so depending upon the $_POST array the different results are loaded and variable $total containing num_of_pages is modified as the 1st block of php code shows now the first page displays 1st 10 results from data base using offset 0 or ofset = IDX10-10 if id is set but problem is that it only works for default results i.e when all results are displayed and filter is not applied but when user searches through a filtered 1st 10 filtered results are displayed but when user clicks the next page it does not work because $_POST is unset which was checked by the php If conditions in above php code. so my question is how can i send $_POST[] along with the id to make it work. Any help would be appreciated. Thanks.

You can't send POST variables through a link. You need to use GET.
Link
//the link will reflect some_page.php?name1=value1&name2=value2...etc
On the PHP side use the $_GET or $_REQUEST variable, instead of $_POST.
