How to show the clicked table row id in the address bar - php

Question

I have a PHP based website for jobs. I echo all the jobs from database in a table below. When i click on a job in table row it shows the job details in an iframe beside the table.
This is the code of the table and iframe index.php
<table class="table1">
<tr>
<td colspan="3">
<?php
include "job.header.php";
?>
</td>
</tr>
<tr>
<td width="30%">
<div>
<?php
require "module/job.call.php";
?>
</div>
</td>
<td width="60%">
<iframe name="content" src="../module/job.unclicked.php">
</iframe>
</td>
<td width="20%"> </td>
</tr>
</table>
This is the code that i call jobs from the database job.call.php
<?php
$result = mysqli_query($conn,"SELECT * FROM job where approved='1' ORDER BY `CreatedTime` DESC");
echo "<table id='maintable' class='table-fill' border='0' cellpadding='0' cellspacing='0'>
<tr>
<th position='fixed' overflow='hidden' width='10%'>Job Title</th>
<th position='fixed' width='5%'>Company Name</th>
<th width='5%'>Closing Date</th>
</tr>";
while($row = mysqli_fetch_array($result) ) {
if (strlen($row['positiontitle']) > 20)
$row['positiontitle'] = substr($row['positiontitle'], 0, 60) . "...";
echo "<tr ref='job.details.php?id=".$row['id']."' target='content' class='positiontitle-link'>";
echo "<td><font style='text-shadow: none;'>" . $row['positiontitle'] . "</font></a></td>";
echo "<td>" . $row['companyname'] . "</td>";
echo "<td>" . $row['closingdate'] . "</td>";
echo "</tr>";
}
echo "</table>";
mysqli_close($conn);
?>
I want that when i click on the job in the table row then the address bar should take the id of the job. because if someone wants to share the job then they should just send that address for specific job.
Now it show like this
I want that it should look like this
