Session Uid in A href

[TehCrayz]

Hello, i havn'nt used php for a while because i gave up. But now im back to give it another try...So i fail straight away and need a solution to this.

I have been following the profile tutorial and have a profile on uid 1. But i don't know to be able to make that when i click on profile, it will take me to Profiles/profile.php?uid=""
$SESSION['uid'']???
[syntax=php] <li><a href=""><i class="icon-user"></i>Profile</a></li>
<li><a href="#"><i class="icon-cog"></i>Settings</a></li>
<li><a href="Login/logout.php"><i class="icon-remove"></i>Log out</a></li>[/syntax]

$_SESSION['uid'] will always be the ID of the currently logged in user, so using that in your url will be the equivalent of a "My Profile" link. I.E it will always take you to your own profile.

There are a multitude of ways to get an id into the url, but I'm gonna need more info on what you're trying to do exactly to be able to help with that

Basically, on the main page, it says the users name, they click it. It's a drop down, and it says "Profile", and so when they click it, it takes them to their profile. Simple.

<a href="*insert thingy here*"><i class="icon-user"></i>Profile</a></li>

I just don't know how to add it in.

[Temor]

Oh, that would be really simple

[syntax=php]
<a href="Profiles/profile.php?uid=<?php echo $_SESSION['uid'];?>"><i class="icon-user"></i>Profile</a></li>
[/syntax]

If you have the users ID stored in $_SESSION['ui'd], and your profile.php page is located in Profiles/, then this will work.

[EDIT] Or, if it doesn't do what's below, it just takes me to uid=1


When i change it to that, i get this in the URL:

http://localhost/Quodec/Profiles/profil ... 20%3Cb%3EC:\xampp\htdocs\Quodec\pictures.php%3C/b%3E%20on%20line%20%3Cb%3E417%3C/b%3E%3Cbr%20/%3E

...I don't get it :/

[Temor]

That's because you don't have a value in $_SESSION['uid'].

Where are you storing the logged in user ID?

[TehCrayz]

What do you mean by that?

[syntax=php]<?php

function user_exists($user){
$user = mysql_real_escape_string($user);

$total = mysql_query("SELECT COUNT(`ID`) FROM `users` WHERE `Username` = '{$user}'");

return (mysql_result($total, 0) == '1') ? true : false;
}

function valid_credentials($user, $pass){
$user = mysql_real_escape_string(htmlentities($user));
$pass = sha1($pass);

$total = mysql_query("SELECT COUNT(`ID`) FROM `users` WHERE `Username` = '{$user}' AND `Password` = '{$pass}'") or die(mysql_error());

return (mysql_result($total, 0) == '1') ? true : false;
}


function add_user($user, $pass){
$user = mysql_real_escape_string(htmlentities($user));
$pass = sha1($pass);

mysql_query("INSERT INTO `users` (`Username`, `Password`) VALUES ('{$user}', '{$pass}')");
}

?>[/syntax]
??

[Temor]

Well, when you log a user in, you set some values in $_SESSION, do you not?
You need to grab the users ID from your Database and insert it into $_SESSION['uid'], otherwise you have no value in $_SESSION['uid'], and trying to grab a value from a variable with no value isn't the easiest thing to do.

[TehCrayz]

Ah, so you're trying to say that right now $_SESSION['uid'] isn't getting the IDs from the database??

...


I'm confused...

[Temor]

Yeah, you're never assigning a value to $_SESSION['uid'].

[TehCrayz]

So uh, How can i fix this issue?

Sorry, i'm kinda a noob at PHP.

[Temor]

Follow the tutorial again It's in there, you just missed it I guess.

It's the login part. You need to set the $_SESSION variable to "log in" the user.

Ok, i'll look back on the tutorial. Thanks.
