Am I understanding this function

[jim.davidson]

function isAuthorized($strUsers, $strGroups, $UserName, $UserGroup) {

$isValid = False;

// When a visitor has logged into this site, the Session variable MM_Username set equal to their username.

// Therefore, we know that a user is NOT logged in if that Session variable is blank.

if (!empty($UserName)) {

// Besides being logged in, you may restrict access to only certain users based on an ID established when they login.

// Parse the strings into arrays.

$arrUsers = Explode(",", $strUsers);

$arrGroups = Explode(",", $strGroups);

if (in_array($UserName, $arrUsers)) {

$isValid = true;

}

// Or, you may restrict access to only certain users based on their username.

if (in_array($UserGroup, $arrGroups)) {

$isValid = true;

}

if (($strUsers == "") && true) {

$isValid = true;

}

}

return $isValid;

}

 

 

$MM_restrictGoTo = "not_logged_in.php";

if (!((isset($_SESSION['MM_Username'])) && (isAuthorized("",$MM_authorizedUsers, $_SESSION['MM_Username'], $_SESSION['MM_UserGroup'])))) {

$MM_qsChar = "?";

$MM_referrer = $_SERVER['PHP_SELF'];

if (strpos($MM_restrictGoTo, "?")) $MM_qsChar = "&";

if (isset($QUERY_STRING) && strlen($QUERY_STRING) > 0)

$MM_referrer .= "?" . $QUERY_STRING;

$MM_restrictGoTo = $MM_restrictGoTo. $MM_qsChar . "accesscheck=" . urlencode($MM_referrer);

header("Location: ". $MM_restrictGoTo);

exit;

}

 

Am I sending the following to isAuthorized function

 

"" as $strUsers

$MM_authorizedUsers as $strGroups

$_SESSION['MM_Username'] as $Username

$_SESSION['MM_UserGroup'] as $UserGroup

 

It returns False and I thing it's because of "" as $strUsers. Am I reading this right?

 

Any help will be appreaciated
