How to use cookie data in a custom module?

kiltannen · **How to use cookie data in a custom module? -** 10-17-2004, 07:11 PM

I have a standalone application which uses session_register to handle it's authentication.

This application has previously been "sort of" integrated into 'Nuke - I say sort of because the user table is still seperate.

I would like to have this application integrate more tightly into Nuke.

I want to use Nuke's own user-table [adding around 6 extra fields of data - essentially access levels - to the user table] and I expect that if I am going to do this I will need to use the cookies to hold the "extra" variables that my application makes use of.

I have read a lot of the documentation - and I have tried to read the code - but I am not completely sure how the cookie/ login process works.

Can somebody please tell me how I will get the cookie to store up to 6 extra fields of information about a user - and make that information available to the scripts?

You may wish to make a simillar function to the nuke's

Code:

function docookie($setuid, $setusername, $setpass, $setstorynum, $setumode, $setuorder, $setthold, $setnoscore, $setublockon, $settheme, $setcommentmax) {
    $info = base64_encode("$setuid:$setusername:$setpass:$setstorynum:$setumode:$setuorder:$setthold:$setnoscore:$setublockon:$settheme:$setcommentmax");
    setcookie("user","$info",time()+2592000);
}

this is used to set the user_id, username, password, news numbers in home, mode/order/thold/score in news comments, custom user block, theme and comment max.
You may want to make somethine like

Code:

function docookie($var1, $var2, $var3, $var4, $var5, $var6) {
    $info = base64_encode(" $var1:$var2:$var3:$var4:$var5:$var6");
    setcookie("mycookie","$info",time()+2592000);
}

In nuke's code you can get the cookies back with cookiedecode($user); and cookie[0] is user_id, $cookie[1] is the username etc.
so we have

Code:

function cookiedecode($user) {
    global $cookie, $prefix, $db, $user_prefix;
    $user = addslashes($user);
    $user = base64_decode($user);
    $cookie = explode(":", $user);
    $result = $db->sql_query("SELECT user_password FROM ".$user_prefix."_users WHERE username='$cookie[1]'");
    $row = $db->sql_fetchrow($result);
    $pass = $row['user_password'];
    if ($cookie[2] == $pass && $pass != "") {
	return $cookie;
    } else {
	unset($user);
	unset($cookie);
    }
}

u will need to make a simillar function like

Code:

function myfuction($mycookie) {
global $user;
if (is_user($user)) {
$mycookie = base64_decode($mycookie);
$mycookie = explode(":", $mycookie);
return $mycookie;
} else {
unset($mycookie);
}
}

Thats a bit too much don't u think? Theres a more simple way to do with $userinfo, but u asked how to do it with cookies so :P
note: code hasn't been tested, made this while typing this reply.

Thank you very much for this - I don't mind so much if I don't use the cookie - could you tell me more about the $userinfo?

it's very simple, if you make the 6 rows in the (prefix)_users then u can get them by using.

Code:

getusrinfo($user);
$userinfo['myvar1'];
$userinfo['myvar2'];

I preffer this way because is more fast and it doesn't need all those functions to get the cookies etc. Like i did in my project one global getusrinfo($user); so it won't need it all the time and i'm setting the $userinfo array as global.

After some delay I am working on this again

So I now have another question that I hope someone can help with...

I am now getting this error message:

Code:

Fatal error: Call to undefined function: getusrinfo() in /home/kdp008/public_html/modules/GenAdmin/checklogin.php on line 6

In essence - My app has some processing scripts which do not act within the "nuke" environment. BUT they have need for some of the user variables - so maybe I do need to be do this using the cookie?

I am thinking I would like to add some extra information to the cookie that is used by nuke & then I xan possibly use the "cookiedcode" function almost as a standalone to pull data out of the current cookie...

Even after looking at the code above I am not sure of how to add extra fields to be stored in the cookie - does anybody have some ideas?
