Searches not clearing properly with new DataAssist

Using the latest version of DataAssist for the first time and have a problem that I never ran into with the older version. When I do a search and get to the results page, the search functions properly. However, when I click back to a fresh copy of the results page (same page without the URL string search criteria), the page is still displaying the same previous search results rather than all records as it should.

I'm not sure where to go or how to troubleshoot. Anyone have suggestions?

the search is stored in a session variable, this is done so that search results will be retained when using the paging controls.
the session will be name using the following naming convention:
WADbSearch1_<page_name>


so on Products_Results.php, the session would be named:
WADbSearch1_Products_Results


you can create a link to clear the results passing a query string variable:
<a href="Products_Results.php?clear=true">Clear Results</a>

then add the following code at line 1 of the results page:

<?php

@session_start();

if(isset($_GET['clear']) && $_GET['clear'] == "true") {if(isset($_SESSION['WADbSearch1_Products_Results'])) unset($_SESSION['WADbSearch1_Products_Results']);}

?>

Worked perfectly.

you're welcome.

I'm still using this technique to clear search results. I'd like to hide the button to clear the search results and only show it if the user has actually searched (as this is the results page with data assist, most of the time users just click in to view the full recordset, in which case having a "clear search" button is unnecessary and confusing).

So would one go about constructing a 'show if session variable is set' in PHP?

The code would look something like this:
<?php if(isset($_SESSION['sessionName']) && $_SESSION['sessionName'] != "") { ?>
clear search link
<?php } ?>

where sessionName is the name of the session to check.
