// Search form providing access to the main fields of the database.
// It offers some output options (like how many records to display per page)
// and let's you specify the output sort order (up to three levels deep).
// Incorporate some include files:
include 'initialize/db.inc.php'; // 'db.inc.php' is included to hide username and password
include 'includes/header.inc.php'; // include header
include 'includes/footer.inc.php'; // include footer
include 'includes/include.inc.php'; // include common functions
include 'initialize/ini.inc.php'; // include common variables
// --------------------------------------------------------------------
// START A SESSION:
// call the 'start_session()' function (from 'include.inc.php') which will also read out available session variables:
start_session(true);
// --------------------------------------------------------------------
// Initialize preferred display language:
// (note that 'locales.inc.php' has to be included *after* the call to the 'start_session()' function)
include 'includes/locales.inc.php'; // include the locales
// --------------------------------------------------------------------
// (1) Open the database connection and use the literature database:
connectToMySQLDatabase(); // function 'connectToMySQLDatabase()' is defined in 'include.inc.php'
// If there's no stored message available:
if (!isset($_SESSION['HeaderString']))
$HeaderString = $loc["SearchMain"].":"; // Provide the default message
else

// Note: though we clear the session variable, the current message is still available to this script via '$HeaderString':
deleteSessionVariable("HeaderString"); // function 'deleteSessionVariable()' is defined in 'include.inc.php'

// ('' will produce the default 'Web' output style)
