POST/SESSION variables and pagination

Hi folks, I have been working on a property listing search for a company for a while now and have hit a roadblock. I have searched the net up and down. A lot of Google results lead to this site, but I have never been able to get it to work.

Here's the setup-

The user submits search criteria via POST. The results php page pulls the $_POST array and displays the results with pagination of 20 results per page with links for Next/Previous.

Clicking on the pagination links loses the variables, whether I simply used $_POST or whether I coded, for instance, $_SESSION['county'] = $_POST['county']; at the top of the script. I, of course, am using session_start(); at the top of the scripts. I have tried all manner of responses regarding sessions,globals,php.ini, and anything else.

The pagination links uses a query string that refers to PHP_SELF and looks like
"http://localhost/advancedsearch.php?offset=21"
where the offset is the 2nd page of 20 results.

Does anyone have any ideas?

Using a hypelink does not generate the POST array .This is only generated from a form. You need to pass the variables as URL variables or as SESSION variables

Thanks for the response! I knew I had to use session variables, but it just wasn't working. Apparently I missed something, because I put this code in and now everything works great-

foreach($_POST as $k => $v)
{
$_SESSION[$k] = $v;
}

The strange thing is, I used this before and it didn't work. I must have mucked it up elsewhere. Thanks though! It works.

session_start();

if (! isset session [query])
{build up query using your post variables;
assign / set a session[query];
}

rest of your code (db connection, pagination, echo results, bla bla)
