echo doesn't print the variable values when using a single quoted string.
ie:

$id = 1;
echo "<td>$id</td>"; // output: "<td>1</td>"
echo '<td>$id</td>'; // output: "<td>$id</td>"

there are a number of ways you could get around this issue, one would be to change those two link lines to be like this

echo '<td><a href="update_tanent.php?id=',$id,'">Edit</a></td>';

(for more information, check the php man pages ;)

On the receiving page you need to use

$id = $_GET['id'];

not $_POST as you are not posting the data (you would be if using a form to pass the data) you are sending in a URL and therefore need to use $_GET.

I'm having a similar problem.
My first page is passing an ID value. This is the url of my 2nd page:
http://localhost/ProductPresentation/Product_Dets.php?Product_id=2

This is the code from my 2nd page.

$product = $_GET['id'];
$productquery = "SELECT * FROM productdets WHERE Product_id=".$product;
$row = mysql_query($productquery);

print $row['SeriesName'];

However this code brings back this error: Notice: Undefined index: id
Haven't I already defined 'id'? What am I missing?

Thank you! I was unaware that had to match.
Now I get the error: Undefined index: Product_id

But it works in my browser.
Strange.

Thanks for your help.
