PHP - Login To Carry The User_id

Hello all...fairly new to this php/mysql thing... working on my final project thats due in about 24 hours... and i hit a rut...
im making a pretty basic, online classifieds site. users can sign up, login, post new listings and view others listings by clicking on different categories. the problem i am having right now is this...When the user clicks on "My listings" i need it to pull only the listings that were created by that users user_id, which is the primary key in my user_info table...my professor suggested storing it in hidden field through the login submit button...very confused and frustrated... any help is much appreciated...

There is  something wrong with my statement it is not returning sql queries  results based on matching the url based based userid to match with the table user_id and get the Ablum id  and Album name:

Please hlep:

Code: [Select]
if(isset($_GET['userid']))
{
$db =& JFactory::getDBO();
$user =& JFactory::getUser();
        $id = $user->id;


$album_id = $_GET['userid'];
$query = 'SELECT user_id, id, format_id, year, name FROM #__muscol_albums WHERE user_id = ' . $album_id;
//$query = 'SELECT user_id FROM #__muscol_albums WHERE id = ' . $album_id ;
$result = mysql_query($query) or die('Error, No Album Search failed');
list($name, $user_id, $id, $year) = mysql_fetch_array($result);


echo $id;

//exit;
}

hi

i need help an idea how can i separate members from admins
since i dont know how to create login form i used tutorial ( http://www.youtube.com/watch?v=4oSCuEtxRK8 )   (its session login form only that i made it work other tutorials wre too old or something)
how what i want to do is separate members and admins because admin need more rights to do
now i have idea but dont know will it work like that
what i want to do is create additional row in table named it flag and create 0 (inactive user) 1 (member) 2 (admin) will that work?
and how can i create different navigation bars for users and admins? do you recommend that i use different folders to create it or just script based on session and flag?

Hello guys,

Is there on web any updated tutorial on how can I add Facebook login on my simple php login script?

Hi guys.

What I want to create is really complicated. Well I have a login system that works with post on an external website.
I have my own website, but they do not give me access to the database for security reasons, therefore I have to use their login system to verify my users.
What their website does is that it has a post, with username and password. The POST website is lets say "https://www.example.com/login".
 If login is achieved (i.e. username and password are correct), it will redirect me to "https://www.example.com/login/success" else it will redirect me to "https://www.example.com/login/retry".

So I want a PHP script that will do that post, and then according to the redirected website address it will return me TRUE for success, FALSE for not successful login.

Any idea??

Thanks

	$password = mysqli_real_escape_string($conn, $_POST['password']);
	$result = mysqli_query($conn, "SELECT * FROM users WHERE email = '" . $email. "' and pass = '" . md5($password). "'");
	if ($row = mysqli_fetch_array($result)) {

Hi everyone i wonder if you can help me he

I need a script for a login and check login- create cookie.

Here is my form:

<form method="post" action="check_login.php">
<p>
<input type="submit" name="Submit2" value="go" />
</fieldset>
</p>
</form>

that sends it to check_login (which BEFORE i deleted something by accident, used to take me to a username and password box)

But now all it does is send me straight to the memebrs area???


Can i change the check_login.php script to make it work correctly:

login_sumbit.php       I am unable to see the    $message = 'Welcome '.$phpro_username;   that the successful login should be generating

I am trying to change my web site to user only to public view. I still need users to be able to log in so they can edit things. I did a quick fix to allow everyone to view things by removing the ! from the sessions. How ever with that when i try to log in it just loops to login.php. There are links on the page that only admins will be able to see.

Here is my session with the removed !.

Code: [Select]
<?php  session_start(); 
   
if($_SESSION['login']){
$_SESSION['rank'];
$_SESSION['loggedinusername'] = $loggedinusername;
$_SESSION['loggedinuseremail'] = $loggedinuseremail;
header("location:login.php");
}
$rank=$_SESSION['rank'];
$loggedinusername=$_SESSION['loggedinusername'];
$loggedinuseremail=$_SESSION['loggedinuseremail'];
?>

How would i got about allowing eveyone to see this page but the log in still work?

If you need anymore code let me know

Thank you

I have a user database so members can log in to my site, what I want to do is when they first login, I want a message to pop up for them to confirm they have read something, but once they confirm it has been read I don't want it to pop up anymore after that, how would I do that?

Thanks
