Try the following (change the query to match your table and values

<h3>Comments:</h3>

<table>
<tr class="row-a">
<td class="first"></td>
<td>
<?php
include"header.php";

if($_POST['submit'])
{
                $post = $_POST["comment"];
                $by = $_POST["name"];
	$add = "INSERT INTO `post` values(`post_content`,`post_by`,) ('$post','$by')";
	$add_values = mysql_query($add) or die(mysql_error());
}

$sql="SELECT post_content,post_by FROM post ORDER BY topicsID";

$result=mysql_query($sql)or die(mysql_error());
while($row=mysql_fetch_array($result))
{
	echo"<strong>{$row['post_by']}</strong>:  {$row['post_content']}"."</br>";
}


?>
</td>

</tr>
</table>

<h3>Post your comments here</h3>
<form action='<?php $_SERVER['PHP_SELF']; ?>' method='post'>
<textarea name="comment" id="content" style="width:400px;height:50px;background-color:#D0F18F;color:#000000;font:15px/20px cursive;scrollbar-base-color:#638E0D;"></textarea>
<br />	
Name:<input type="text"name="name"/> 		

<input class="button" type="submit"name="submit"value="submit" />
</p>		
</form>

Try it now (there was a syntax error in the query):

<h3>Comments:</h3>

<table>
<tr class="row-a">
<td class="first"></td>
<td>
<?php
include"header.php";

if($_POST['submit'])
{
                $post = $_POST["comment"];
                $by = $_POST["name"];
	$add = "INSERT INTO `post` values(`post_content`,`post_by`) ('$post','$by')";
	$add_values = mysql_query($add) or die(mysql_error());
}

$sql="SELECT post_content,post_by FROM post ORDER BY topicsID";

$result=mysql_query($sql)or die(mysql_error());
while($row=mysql_fetch_array($result))
{
	echo"<strong>{$row['post_by']}</strong>:  {$row['post_content']}"."</br>";
}


?>
</td>

</tr>
</table>

<h3>Post your comments here</h3>
<form action='<?php $_SERVER['PHP_SELF']; ?>' method='post'>
<textarea name="comment" id="content" style="width:400px;height:50px;background-color:#D0F18F;color:#000000;font:15px/20px cursive;scrollbar-base-color:#638E0D;"></textarea>
<br />	
Name:<input type="text"name="name"/> 		

<input class="button" type="submit"name="submit"value="submit" />
</p>		
</form>

It should work now

The error "Undefined index id" is referring to the $_GET['id'] variable. since you don't sent anything using the GET method it comes up us undefined.

You can edit that and line and use the following:

 


				<span class="date"><?php 
			include"header.php";
			if(isset($_GET['id']) //CHECK IF GET ID IS SET ELSE GET IT FROM HIDDEN FIELD IN THE FORM
			{
				$topicid=$_GET['id'];
			}
			else
			{
				$topicid=$_POST['id'];
			}
			$sql="SELECT*FROM topics WHERE topicsID=$topicid";
			$result=mysql_query($sql) or die(mysql_error());
			while($row=mysql_fetch_array($result))
			     {
					echo"{$row['topics_date']}";
				}
			?></span>	
			</p>

		</div>


			<h3>Comments:</h3>

				<table>
				<tr class="row-a">
					<td class="first"></td>
					<td>

					<?php
                       include"header.php";
                       if(isset($_POST['submit']))
                       {
                        $comment=mysql_real_escape_string(trim($_POST['comment']));
                        $name=mysql_real_escape_string(trim($_POST['name']));
                        if($comment!=='' && $name!=='')
                        {
                        $ins="INSERT INTO post(post_content,post_by)VALUES('$comment','$name')";
                        mysql_query($ins) or die(mysql_error());
                         $sql="SELECT post_content,post_by FROM post ORDER BY topicsID";  
                            $result=mysql_query($sql)or die(mysql_error());
                                while($row=mysql_fetch_array($result))
                             {

                               echo"<strong>{$row['post_by']}</strong>:  {$row['post_content']}"."</br>";
                             }
                               }

Thanks it works fine but i discover now that every comment in my POST table get echoed out so i introduced a WHERE clause in the SELECT query but it will only echo out only one comment even though i comment again and again.this is the new code:

<p>Posted by <a href=""><?php 
			include"header.php";
			if(isset($_GET['id']))
			{
			$topicid=$_GET['id'];
			}
			else
			{
			$topicid=$_POST['id'];
			}
			$sql="SELECT*FROM topics WHERE topicsID=$topicid";
			$result=mysql_query($sql) or die(mysql_error());
			while($row=mysql_fetch_array($result))
			     {
                 		echo"{$row['topics_by']}</a></p>";



                 		echo"<p> {$row['topics_subject']}";

					 echo"  <p align='left'><img src='speakout_1.png'/>";
                 	
			echo"{$row['topics_content']}";
			echo"<p class='post-footer align-right'>";					

				echo"<a href='' class='comments'>";
session_start();
if(isset($_SESSION['views']))
$_SESSION['views']=$_SESSION['views']+1;
else
$_SESSION['views']=1;
echo"Comments:".$_SESSION['views'];

echo"</a>";
				echo"<span class='date'>";

			echo"{$row['topics_date']}";
			}
			?></span>	
			</p>

		</div>


			<h3>Comments:</h3>

				<table>
				<tr class="row-a">
					<td class="first"></td>
					<td>

					<?php
                       include"header.php";
                         $sql="SELECT post_content,post_by FROM post WHERE postID='$topicid'";  
                            $result=mysql_query($sql)or die(mysql_error());
                                while($row=mysql_fetch_array($result))
                             {

                               echo"<strong>{$row['post_by']}</strong>:  {$row['post_content']}"."</br>";
                             }
						  if(isset($_POST['submit']))
                       {
                        $comment=mysql_real_escape_string(trim($_POST['comment']));
                        $name=mysql_real_escape_string(trim($_POST['name']));

                        if($comment=='' && $name=='')
                        {
					echo"You can not leave any field blank";
					}
					else{
                        $ins="INSERT INTO post(post_content,post_by)VALUES('$comment','$name')";
                        mysql_query($ins) or die(mysql_error());
                               }
						   }
						   
                                       ?></td>

				</tr>
				</table>
