Pass value from one page to another in PHP without using URL - php

Question

I used to pass value from one page to another using session. E.g
page1.php
<?php
session_start();
$_SESSION["id"] = $id;
?>
page2.php
<?php
session_start();
echo $_SESSION["id"];
?>
But for the following case i don't know how can i pass the id to the next page. This code is used to display group of people and the action column have an option to view the people details.
<table>
<thead>
<tr>
<th>Name</th>
<th>Status</th>
<th>Created</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<?php
$DBSystemAccess = dbSelectByWhere("SystemAccess", "", "ORDER By Timestamp");
while ($SystemAccessDB = dbFetchArray($DBSystemAccess)) {
?>
<tr>
<?php
echo '<td>' . dbGroupNamebyId($_SESSION['PI_ID']) . '</td>';
echo '<td>' . $Status . '</td>';
echo '<td>' . $SystemAccessDB['timeStamp'] . '</td>';
echo '<td>' . '<a href="adetails.php?ID=' . $SystemAccessDB['id'] . '" >View</a> </td>'
?>
</tr>
<?php } ?>
</tbody>
How can i replace <a href="adetails.php?ID=' . $SystemAccessDB['id'] . '" >View</a> to not showing ID in the URL?

Answer 1

Please try this with the hyper link it is not possible to hide the GET data.We need to use POST method.
<table>
<thead>
<tr>
<th>Name</th>
<th>Status</th>
<th>Created</th>
<th>Action</th>
</tr>
</thead>
<tbody>
<?php
$DBSystemAccess = dbSelectByWhere("SystemAccess", "", "ORDER By Timestamp");
while ($SystemAccessDB = dbFetchArray($DBSystemAccess)) {
?>
<tr>
<?php
echo '<td>' . dbGroupNamebyId($_SESSION['PI_ID']) . '</td>';
echo '<td>' . $Status . '</td>';
echo '<td>' . $SystemAccessDB['timeStamp'] . '</td>';
echo '<form name="test" method="post" action="testing.php">';
echo '<input type="hidden" name="hidden_name" value="'.$SystemAccessDB['id'].'"/>';
echo '<button type="submit">View</button>';
echo '</form>';
?>
</tr>
<?php } ?>
</tbody>
When you will click it will redirect to testing.php with hidden value 'hidden_name' on which you can further query according to that value.
