<input type="hidden" name="username" value="<?php echo ($_SESSION['MM_Username']) ?>" >
I would like to echo it out. But no matter how I try there is an error. Can some one help me out?
<?php echo "<input type='hidden' name='username' value='($_SESSION['MM_Username'])'"; ?>
Do you have session_start(); somewhere at the top of the script?
<?php echo $_SESSION['MM_Username']; ?>
should work. If it does not, then MM_Username is empty.
Try to do this... Remember one thing, you must start session at the top of your coding. Then, take a variable $a and store the value of $_SESSION['MM_Username']; ?> into $a,
i.e. $a=$_SESSION['MM_Username'];
now echo $a,
if it does not then either you must have an empty entry or as you are trying to display the result in hidden field you will not be able to get anything.
Take a good look at my page it begins with the session_start(); Then in my HTML it contains variables i have echoed. Hope it helps.
<?php
if (!isset($_SESSION)) {
session_start();
}
$MM_authorizedUsers = "";
$MM_donotCheckaccess = "true";

function isAuthorized($strUsers, $strGroups, $UserName, $UserGroup) {
// For security, start by assuming the visitor is NOT authorized.
$isValid = False;
// When a visitor has logged into this site, the Session variable MM_Username set equal to their username.
// Therefore, we know that a user is NOT logged in if that Session variable is blank.
if (!empty($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;
