Is it possible to get the value of the text in an anchor tag when the link is clicked? e.g
if you have <a href=#>Tables</a>
is it possible to retrieve the value Tables in a variable like a session variable and use it across your pages?
I have several categories of items(which are links) and i want to be able to get the value of any category clicked and use it pull products listed in that category from my database.
Thanks.

EDIT:
This what i tried
<a href=# onclick= <?php $_SESSION[value] = Table ?>>Table</a>
But didn't get the value.
Apologies, should have posted it earlier

As posted, your code does not submit so your PHP is never processed:

<a href=#

When you have # as the href value, no new request is submitted. However, you can modify your anchor to submit the category back to your PHP script like this:

<a href=yourscript.php?category=Table>Table</a>

Then in yourscript.php you can read the value using $_GET:

$selected_category = $_GET['category']; // Get 'Table'

To set the value in your session, first be sure that you have started your session near the top of your script:

session_start();

then save the value like this:

$_SESSION['selected_category'] = $_GET['category'];
