?? How do I post that on the forum?
Screenshot?
(final sql code)
I have 12 fields

id_user
name
email
phone_number
username
password
confirmcode
user_picture
user_about
user_location
user_gender
user_inbox

id_user is int with 11 , it is not null, set to auto increment and is primary key.
From my understanding it should be storing a number since each user on my page has an assigned ID
which you can see by manually changing the "uid=" numerical ending.

the same way you post all code.

$result = mysql_query("SELECT `user_id` FROM `users` WHERE `username` = '{$user}' AND `password` = '{$pass}'");

does it look like that? If not, then what does it look like?

I have this

function validate_credentials($user, $pass){
    $user = mysql_real_escape_string($user);
    $pass = sha1($pass);
 
    $result = mysql_query("SELECT `user_id` FROM `users` WHERE `username` = '{$user}' AND `password` = '{$pass}'");
   
    if (mysql_num_rows($result) != 1){
        return false;
    }

You forgot the last return line. What you have now is : if the information is invalid -> Return false ( Validation failed ). If the information is correct -> Do nothing. You want to return the users ID.
That is this line:

  return mysql_result($result, 0);

The entire function should look like this:

function validate_credentials($user, $pass){
    $user = mysql_real_escape_string($user);
    $pass = sha1($pass);
 
    $result = mysql_query("SELECT `user_id` FROM `users` WHERE `username` = '{$user}' AND `password` = '{$pass}'");
   
    if (mysql_num_rows($result) != 1){
        return false;
    }
 
    return mysql_result($result, 0);
}

sorry but it didn't change anything.

(also this is the session problem I mentioned having in the other forum topic I posted)

I made a discovery which may or may not be useful to you.

When I am logged in my account where the user id = 1.... I get

this is what shows http://www.yourtechview.com/source/profile.php?uid=id

when I am logged into my other account where the user id = 14.... I get

http://www.yourtechview.com/source/profile.php?uid=id

It seems you were right that if anyone is logged in it will return just 1 or id. (I assumed this was only for my account
and I made another account which proved to be false)

Would it be easier to change the method from profile.php?uid=# to profile.php?uid=username ?

I think this would be much easier than having their user id at the end.

The principle still remains the same.

$result = mysql_query("SELECT `user_id` FROM `users` WHERE `username` = '{$user}' AND `password` = '{$pass}'");

The only difference is that you select username instead of user_id. And because this clearly fails to return the ID, it won't return a username either.

$result = mysql_query("SELECT `username` FROM `users` WHERE `username` = '{$user}' AND `password` = '{$pass}'");

And by the way, I see your id field is called id_user, not user_id. You might want to change that.

no dice.
I just get id at the end =(

Unless you're actually storing "id" as the id, this does not make sense. It should return the ID. The same exact code does what it's supposed to do on my system.

I have to admit I'm stumped.

My suggestion is to scrap that insanely clotted login script you've downloaded and instead try and follow along on some of Jacek's tutorials to create your own. You can do without the majority of the stuff in your script. It will be easier to read and understand as well as maintain and build upon. And you'll learn some in the process as well. Just downloading something someone else wrote wont teach you much.

Just my two cents.

Thank you for your time.
