bueno me pasa lo siguiente... estoy haciendo una pagina con registro de usuarios. al registrarse, voy al login e hice una cosa para probar y no me funciona,me pasa lo siguiente, al entrar con el login le pido que me de el nombre de usuario,pero no me lo da,voy al logout, se cierra la sesion, voy a user.php y me muestra la sesion anterior!!
igual voy a restringir el user.php
aca van los codigos:
user.php
<?php
require('config.php');
require('functions.php');
//make connection to dbase
//build and issue the query
$sql ="SELECT * FROM $table_name";
?>
<html>
<head>
<title>Bienvenidos</title>
</head>
<body>
<p>Entraste con el Nick:</p>
<?php
echo $_SESSION[user_name];
?>
<form name="form1" method="post" action="username.php">
<label>Cambiar nombre de usuario
<input type="text" name="username.php">
</label>
<p> </p>
<label></label>
<input type="submit" name="Submit" value="Cambiar">
</form>
<p> </p>
</body>
</html>
config.php no hace falta...
username.php
<?php
//function to get the date
function last_login()
{
return $date;
}
//function that sets the session variable
function sess_vars($base_dir, $server, $dbusername, $dbpassword, $db_name, $table_name, $user, $pass)
{
//make connection to dbase
$sql = "SELECT * FROM $table_name WHERE username = '$user' and password = password('$pass')";
//get the number of rows in the result set
//set session variables if there is a match
if ($num != 0)
{
{
$_SESSION[first_name] = $sql -> firstname;
$_SESSION[last_name] = $sql -> lastname;
$_SESSION[user_name] = $sql -> username;
$_SESSION[password] = $sql -> password;
$_SESSION[group1] = $sql -> group1;
$_SESSION[group2] = $sql -> group2;
$_SESSION[group3] = $sql -> group3;
$_SESSION[pchange] = $sql -> pchange;
$_SESSION[email] = $sql -> email;
$_SESSION[redirect] = $sql -> redirect;
$_SESSION[verified] = $sql -> verified;
$_SESSION[last_login] = $sql -> last_login;
}
}else{
$_SESSION[redirect] = "$base_dir/errorlogin.html";
}
}
//functions that will determine if access is allowed
function allow_access($group)
{
if ($_SESSION[group1] == "$group" || $_SESSION[group2] == "$group" || $_SESSION[group3] == "$group" ||
$_SESSION[group1] == "Administrators" || $_SESSION[group2] == "Administrators" || $_SESSION[group3] == "Administrators" ||
$_SESSION[user_name] == "$group")
{
$allowed = "yes";
}else{
$allowed = "no";
}
return $allowed;
}
//function to check the length of the requested password
function password_check($min_pass, $max_pass, $pass)
{
$valid = "yes";
{
$valid = "no";
}
return $valid;
}
?>
en functions.php hay mas cosas pero esta lo que seria la parte de username.
alguna idea?
