Can't show mm_username variable

[garydt]

Hi. I hope someone can help as I've been struggling with this for a few weeks.

On the first php page I have the user register and log in automatically. On the 2nd php page i want to greet the username but the MM_Username variable won't appear on the screen. I'm using Apache2 as the testing server with Dreamweaver 8.02. Where am I going wrong?

 

Here's the code:-

 

<?php require_once('Connections/registration.php'); ?>

<?php

if (!function_exists("GetSQLValueString")) {

function GetSQLValueString($theValue, $theType, $theDefinedValue = "", $theNotDefinedValue = "")

{

$theValue = get_magic_quotes_gpc() ? stripslashes($theValue) : $theValue;

 

$theValue = function_exists("mysql_real_escape_string") ? mysql_real_escape_string($theValue) : mysql_escape_string($theValue);

 

switch ($theType) {

case "text":

$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";

break;

case "long":

case "int":

$theValue = ($theValue != "") ? intval($theValue) : "NULL";

break;

case "double":

$theValue = ($theValue != "") ? "'" . doubleval($theValue) . "'" : "NULL";

break;

case "date":

$theValue = ($theValue != "") ? "'" . $theValue . "'" : "NULL";

break;

case "defined":

$theValue = ($theValue != "") ? $theDefinedValue : $theNotDefinedValue;

break;

}

return $theValue;

}

}

 

// *** Redirect if username exists

$MM_flag="MM_insert";

if (isset($_POST[$MM_flag])) {

$MM_dupKeyRedirect="usernam.html";

$loginUsername = $_POST['username'];

$LoginRS__query = sprintf("SELECT username FROM tablename1 WHERE username=%s", GetSQLValueString($loginUsername, "text"));

mysql_select_db($database_registration, $registration);

$LoginRS=mysql_query($LoginRS__query, $registration) or die(mysql_error());

$loginFoundUser = mysql_num_rows($LoginRS);

 

//if there is a row in the database, the username was found - can not add the requested username

if($loginFoundUser){

$MM_qsChar = "?";

//append the username to the redirect page

if (substr_count($MM_dupKeyRedirect,"?") >=1) $MM_qsChar = "&";

$MM_dupKeyRedirect = $MM_dupKeyRedirect . $MM_qsChar ."requsername=".$loginUsername;

header ("Location: $MM_dupKeyRedirect");

exit;

}

}

 

$editFormAction = $_SERVER['PHP_SELF'];

if (isset($_SERVER['QUERY_STRING'])) {

$editFormAction .= "?" . htmlentities($_SERVER['QUERY_STRING']);

}

 

if ((isset($_POST["MM_insert"])) && ($_POST["MM_insert"] == "form1")) {

$insertSQL = sprintf("INSERT INTO tablename1 (fname, surname, sex, country, email, username) VALUES (%s, %s, %s, %s, %s, %s)",

GetSQLValueString($_POST['fname'], "text"),

GetSQLValueString($_POST['surname'], "text"),

GetSQLValueString(isset($_POST['sex']) ? "true" : "", "defined","1","0"),

GetSQLValueString($_POST['country'], "text"),

GetSQLValueString($_POST['email'], "text"),

GetSQLValueString($_POST['username'], "text"));

 

mysql_select_db($database_registration, $registration);

$Result1 = mysql_query($insertSQL, $registration) or die(mysql_error());

 

$insertGoTo = "recordin.php";

if (isset($_SERVER['QUERY_STRING'])) {

$insertGoTo .= (strpos($insertGoTo, '?')) ? "&" : "?";

$insertGoTo .= $_SERVER['QUERY_STRING'];

}

header(sprintf("Location: %s", $insertGoTo));

}

?><?php

// *** Validate request to login to this site.

if (!isset($_SESSION)) {

session_start();

}

 

$loginFormAction = $_SERVER['PHP_SELF'];

if (isset($_GET['accesscheck'])) {

$_SESSION['PrevUrl'] = $_GET['accesscheck'];

}

 

if (isset($_POST['username'])) {

if ($loginFoundUser) {

$loginStrGroup = "";

 

//declare two session variables and assign them

$GLOBALS['MM_Username'] = $loginUsername;

$GLOBALS['MM_UserGroup'] = $loginStrGroup;

 

if (isset($_SESSION['PrevUrl']) && false) {

$MM_redirectLoginSuccess = $_SESSION['PrevUrl'];

Hello <?php echo $_SESSION['MM_Username']; ?>

</body>

</html>

 

 

[taith]

you have your variable saved into $GLOBALS['MM_Username']... not $_SESSION[MM_Username]

[garydt]

I've changed the GLOBALS into SESSION but it is still not working.

[JasonLewis]

add session_start(); to the very top of your page. the ABSOLUTE top!

[garydt]

Thanks alot for that.
