Create search query with optional fields - Not Working, need suggestions pls
Hi, need help please asap.
I am trying to search/filter records from a DB table and have used the code from the link below -
http://cookbooks.adobe.com/post_Create_search_query_with_optional_fields-16245.html
However when I run the search, the filtered results are not returned, rather I get back all the table records. Also on the view results page I get the following error:
Notice: Undefined variable: query_search in C:\wamp\www\CIWProject\Bugs\ViewSearchedBugs.php on line 91
relating to the following line of code:
$query_search .= ' WHERE ';
Ani ideas/suggestions/solutions greatly appreciated.
The page code in its entirety:
<?php require_once('../Connections/Project1.php'); ?>
<?php
//initialize the session
if (!isset($_SESSION)) {
session_start();
}

$logoutAction = $_SERVER['PHP_SELF']."?doLogout=true";

$logoutAction .="&". htmlentities($_SERVER['QUERY_STRING']);
}
if ((isset($_GET['doLogout'])) &&($_GET['doLogout']=="true")){
//to fully log out a visitor we need to clear the session varialbles
