PHP Login Help

wayne · September 17, 2008

Hi

Im a bit of a novice so need help urgently.

I have created login pages etc for my site which all work fine and dandy.

There are certain pages i want to restrict so that they are only allowed access when logged in. Im using the below code at the top of each page im restricting.

The problem is the user logs in, they call page1 which has the below and correctly allows access. Iif not logged in calls login page) They then call page2 which also has the below code but it has not retained the fact that they have already logged in and prompts them to log in again. It seems only picks up login details for the first page called after they loggied in ande not any subsequent pages.

What do i need to do to the below code in order for it to identify the user is already logged in ?

Hope that makes sense.

<?php

include($_SERVER['DOCUMENT_ROOT']."/access_user_class.php");

$page_protect = new Access_user;

// $page_protect->login_page = "login.php"; // change this only if your login is on another page

$page_protect->access_page(); // only set this this method to protect your page

$page_protect->get_user_info();

$hello_name = ($page_protect->user_full_name != "") ? $page_protect->user_full_name : $page_protect->user;

if (isset($_GET['action']) && $_GET['action'] == "log_out") {

$page_protect->log_out(); // the method to log off

}

?>

I have the below code in access_user_class.php if of any help

function login_saver() {

if ($this->save_login == "no") {

if (isset($_COOKIE[$this->cookie_name])) {

$expire = time()-3600;

} else {

return;

}

} else {

$expire = time()+2592000;

}

$cookie_str = $this->user.chr(31).base64_encode($this->user_pw);

setcookie($this->cookie_name, $cookie_str, $expire, $this->cookie_path);

}

function login_reader() {

if (isset($_COOKIE[$this->cookie_name])) {

$cookie_parts = explode(chr(31), $_COOKIE[$this->cookie_name]);

$this->user = $cookie_parts[0];

$this->user_pw = base64_decode($cookie_parts[1]);

$this->is_cookie = true;

}

You should create a session.

Goldeneye · September 17, 2008

Well as F1Fan said, put session_start(); right after the <?php tag and see if that helps.

Here's more info:

Thanks but still cant get to work.

Tried with <?php session_start(); ?> just in login script page and in landing page and all restricted pages. Tested together, seperatly etc.

No matter what i do after ive navigated to my first page after login it forces the user to login again to few another page.

Here is what is in my login script. Do i need to put some of this into my restricted pages ?

Sorry if silly questions, newbie who is hacking around.

<?php session_start();

include($_SERVER['DOCUMENT_ROOT']."/access_user_class.php");

$my_access = new Access_user;

$my_access->login_reader();

// $my_access->language = "de"; // use this selector to get messages in other languages

if (isset($_GET['activate']) && isset($_GET['ident'])) { // this two variables are required for activating/updating the account/password

//$my_access->auto_activation = false; // use this (true/false) to stop the automatic activation

$my_access->activate_account($_GET['activate'], $_GET['ident']); // the activation method

}

if (isset($_GET['validate']) && isset($_GET['id'])) { // this two variables are required for activating/updating the new e-mail address

$my_access->validate_email($_GET['validate'], $_GET['id']); // the validation method

}

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

$my_access->save_login = (isset($_POST['remember'])) ? $_POST['remember'] : "yes"; // use a cookie to remember the login

$my_access->count_visit = true; // if this is true then the last visitdate is saved in the database

$my_access->login_user($_POST['login'], $_POST['password']); // call the login method

}

$error = $my_access->the_msg;

?>

Does any part of the below script say to log out when leave page ?

include($_SERVER['DOCUMENT_ROOT']."/access_user_class.php");

$page_protect = new Access_user;

// $page_protect->login_page = "login.php"; // change this only if your login is on another page

$page_protect->access_page(); // only set this this method to protect your page

$page_protect->get_user_info();

$hello_name = ($page_protect->user_full_name != "") ? $page_protect->user_full_name : $page_protect->user;

if (isset($_GET['action']) && $_GET['action'] == "log_out") {

$page_protect->log_out(); // the method to log off

}

F1Fan · September 18, 2008

You need a session start on every page. Then, if they log in successfully, save their username in a $_SESSION variable. The next time the login script goes to authenticate, have it check to see if the $_SESSION username variable has been set. If it has, assume authentication. Otherwise, send them back to the login screen to log in.

JonnoTheDev · September 18, 2008

This has absolutely nothing to do with session_start() as your authentication class is cookie based.

You should remove this line.

You need to paste the whole class really as you have only posted a section (post in a code bock so its readable). You also need to post the code that is at the top of each page where a user must be authenticated to access. It is obviously checking for the existence of a cookie which cannot be set correctly.

Thanks, here you go.

This is what the scripts have said to put in the top of each page i want restricted to users logged in.

<?php


include($_SERVER['DOCUMENT_ROOT']."/access_user_class.php"); 

$page_protect = new Access_user;
// $page_protect->login_page = "login.php"; // change this only if your login is on another page
$page_protect->access_page(); // only set this this method to protect your page
$page_protect->get_user_info();
$hello_name = ($page_protect->user_full_name != "") ? $page_protect->user_full_name : $page_protect->user;

if (isset($_GET['action']) && $_GET['action'] == "log_out") {
$page_protect->log_out(); // the method to log off
}
?>

Here is the class file

<?php


session_start();
// error_reporting (E_ALL); // I use this only for testing
require($_SERVER['DOCUMENT_ROOT']."/db_config.php"); // this path works for me...

OK

When you login a user the following method is used:

$this->login_user($user, $password)

A call is then made within the method to

$this->check_user($pass)

. This method checks the database for the existence of the user and returns true on a record returned or false on no record.

If true the following method is called

$this->set_user();

. This method will set the following sessions: 'user', 'pw'. It will then redirect to the next page located in

$this->main_page

.

On the protected pages the following line is checking that you are authenticated:

$page_protect->access_page();

It is checking for the existence of the session variables. Your session_start() is included with the class so should be OK. It is also calling the

$this->check_user($pass)

method to check the user in the database also. If either return false then you are redirected back to the login page.

To debug you will need to print some of the class data to the screen in various methods and make it exit at points to see if the user is being properly located in the database, the session variables exist, none of the methods are returning false when they should be returning true, etc.
