session issues

bliss322

so i'm trying to develop a login authorization script, this is my first attempt at any real session management.

anyway, i'm check to see if the session "user" has any value to it. if not, it calls a login function, pulls from database, ideally creates the user session and reloads the page. problem is, the session doesn't seem to carry over on the reload.

any suggestions?

code:

<?
session_start();
session_register("user","accessLvl");

function login($submit,$login,$password) {

if (!$submit) {
echo "<form name=\"login\" method=\"post\" action=\"\">"
."login&nbsp;<input type=\"text\" name=\"login\">&nbsp;"
."password&nbsp;<input type=\"password\" name=\"password\">&nbsp;"
."<input type=\"submit\" name=\"submit\" value=\"login\">"
."</form>";
} else {
include("ez_sql.php");
$login = $db->get_row("SELECT userName,userPwd FROM users WHERE userName = '$login' && userPwd = '$password'");

if ($login) {

session_register("user");
$user =  $login->userName;

header("Location: ".$_SERVER["SCRIPT_NAME"]);

}else{
header("Location: ".$_SERVER["SCRIPT_NAME"]);
}


}

}

if (!$user) {
login($submit,$login,$password);
}else{
echo "user: $user";
}

oops. got it solved. i hadn't declared global $user inside the function.

well, the way you just did, finding out the error by yourself, you learned something, which is just what you want, right?

ednark

session_register("user","accessLvl");

while you still need session_start(), you shouldn't have to use register() and unregister() anymore.. if you have an even aguelly recent version of php

you can simply use this

check existance with:

isset($_SESSION['user']);

$_SESSION['user'] = 'ednark';

unregister a variable with

$_SESSION['user'] = NULL;

and get a variable with

$i_want = $_SESSION['user'];
