PHP Login Question / Need Help!

[Eliasam13]

Hello, Iv searched everywhere trying to find the answer to my problem...

 

Im trying to make a login form (Username / Password Authentication) and for each user that has a login / password they will be redirected to a specific page..

 

for example if the user "Mike" log's in he will be directed to page1.  If the user "Jon" log's in he will be directed to page2.

 

And really the only login i know how to do is to direct all users to one location...

 

I hope someone can help me!!

what makes page 1 different from page 2?

 

my idea is to associate the primary key of this table with the page number to go to

That sounds like an awful lot of maintenance. Why would you want to do that? You'd be better off with a dynamic approach whereby you pass an ID or a username to the logged-in location, and load the appropriate content based on that variable.

This is what im trying to do... My customer will have there own username and password.

 

Each of the customers will go to a specific page relating to there information.

 

Page 1 Will Have information regarding customer "Mike".  Having information such as his Name and address, his recent purchase, etc..

 

Page 2 Will be the same thing but information related to "Jon".

 

thats what im trying to do..

 

How can I redirect all my cutomers to there OWN specific page in php?

Why don't you just make the account page dynamic by calling from a database.

 

e.g.

 

When the user logs in, start a session calling the username from the form..

 

 

Login process:

 

<?php
session_start();

$username = $_POST['username'];
$password = $_POST['password'];

$sql = mysql_query(sprintf("SELECT * FROM `users` WHERE `username` = '%s' AND `password` = '%s' LIMIT 1", $username, $password)) or die('Error: ' . mysql_error());

if($obj = mysql_fetch_object($sql))
{
  $_SESSION['valid'] = true;
  $_SESSION['username'] = $username;
  echo '<script type="text/javascript">window.location = "account.php";</script>';
}
else
{
  echo 'Your credentials appear to be invalid.';
}
?>

 

 

 

Then for the account page:

 

<?php
session_start();

if($_SESSION['valid'])
{
  $username = $_SESSION['username'];
  $sql = mysql_query(sprintf("SELECT * FROM `users` WHERE `username` = '%s' LIMIT 1", $username)) or die('Error: ' . mysql_error());

  if($obj = mysql_fetch_object($sql))
  {
    echo 'Username: ' . $username;
    echo 'E-Mail Address: ' . $obj->email;
  }
}
else
{
  echo 'You are not logged in.';
}
?>

 

This is a very basic example.

Why do this:

 

echo '<script type="text/javascript">window.location = "account.php";</script>';

 

Why use Javascript for something that could easily be done with header(), remember that not everyone has Javascript enabled.

ok i understand what you mean but for adding the specific customer information i would have to put all that info in mysql right?

[Bramme]

yes indeed. it would be much easier to extend your existing users table like this

 

as it is now (i'm guessing)

user_id | name | password

 

as it should be

 

user_id | name | password | a | field | for | everything | you | want | to | save.

 

And then in your code when the user has entered the correct login and password, you should add smth like $_SESSION['userid'] = $id (where $id could be fetched from the database).

 

Next, you redirect them all to the same page which has a table like

<?php

$userid = $_SESSION['userid'];

$userdata = mysql_fetch_assoc(mysql_query("SELECT * FROM users WHERE user_id = $userid));

echo "<ul>\n<li>Name: $userdata['name']</li>\n<li>Field: $userdata['field']</li>\n</ul>";

?>

Something like that...

Header wouldn't be able to be used along with starting a session at the beginning.

Yes it would.

ob_start; workaround?

You don't need output buffering. Yes, you cannot send headers after output to the browser without using output buffering, but starting a session and assigning session variables does not output anything to the browser.
