make sure to share the relevant code and you have to start the session on each page with session_start() if session_autostart directive in php.ini is not enabled..

Index page:

<?php
session_start();
echo '<p>Your session id is: ' . session_id() . '</p>';

Other page:

<?php
session_start();
echo '<p>Your session id is: ' . session_id() . '</p>';

See if they match if you will ;).

 <?php $q="SELECT * FROM inner_pages WHERE sub_title='6' ORDER BY inner_id DESC limit 0,10";
        $output=mysql_query($q) or die (mysql_error().$q);
          while ($rows=mysql_fetch_array($output)){
          ?>                        
                        <tr>
                            <td align="left"  class="sidebar" style="padding-left:5px;"><a href="abc.php?sub1_id=<?php echo $rows['id']; ?>"><?php echo $rows['inner_title'];?></a></td>
                          </tr>
                          <tr>

<tr>
            <?php 
                $sub_id= $_GET['sub_id'];
                $q="SELECT * FROM post WHERE category ='$sub_id'";
                $output=mysql_query($q) or die (mysql_error().$q);
                while ($rows=mysql_fetch_array($output)){
            ?>                        
                        <tr>
                            <td align="left"  class="sidebar" style="padding-left:5px;"><span class="sidebar" style="padding-left:5px;"><a href="abc.php?p_id=<?php echo $rows['id']; ?>"><?php echo $rows['title'];?></a></span></td>
                          </tr>
                          <tr>
                            <td align="left"><img src="images/horiz_divder.jpg" width="220" height="1" /></td>
                          </tr>
                          <?php } ?>
</tr>

        $output=mysql_query($q) or die (mysql_error().$q);
          $rows=mysql_fetch_array($output);
          ?> 
 <tr>
                    <td height="35" align="left"><h2 style="color:#2C66A1; text-transform:capitalize;"><?php echo $rows['title'];?></h2></td>

Ok so let's clear this up a little bit. You have a page called index.php. It retrieves data from your database. Now which ID do you want to use on page 2, and how do you get to page 2? Do you get there by submitting a form, clicking a link, something like that?

Using the session to save a variable goes as follows, in case you need to use it:

  1. At the start of your page, place the session_start(); command.

  2. You can now save anything on your page in $_SESSION['your_key_name'], e.g. $_SESSION['user_id'] = $user_id;.

  3. You can now also access session information on your page. Let's say that on a previous page you have saved something in $_SESSION['page_id']. You can now access that variable by simply using $_SESSION['page_id'];, e.g. echo $_SESSION['page_id'];.
