Loosing Session ID

sorsha · December 11, 2010

Hello

I am trying to encorporate this php script into my login only section of my project.

When you first go in and go to the page this session is still there, but when you select any letter to play the game it looses the session id and essentially logs you out.

Can any one help. I cant figure this out iv been staring at it for days

Thanks in advance !

<?php

session_name ('YourVisitID');

ini_set('session.use_cookies', 0); // Don't use cookies.

session_start();

include ('./includes/header.inc');

>> Installation

Copy the PHP script and images to the same directory. You can optionally edit the category and list of words/phrases to solve below. You can also add additional characters to $additional_letters and/or $alpha if you want to use international (non-English) letters or other characters not included by default (see further instructions below for those).

To prevent Google from playing hangman, add the line below between <HEAD> and </HEAD>:

=======================================================================================*/

$Category = "Favorite Movies";

# list of words (phrases) to guess below, separated by new line

$list = "GONE WITH THE WIND

# make sure that any characters to be used in $list are in either

# You can use either upper OR lower case of each, but not both cases of the same letter.

What makes you think the value is being lost, rather than not getting set in the first place?

sorsha · December 11, 2010

Well the way I am using this is after you log in your able to get to this game. You click on this link for Hangman and it goes to the game, You can see your session Id in the address bar, and it still shows you as logged in, but as soon as you click on the letter, you have to log in again and start over, and there is no session id in the bar any more

PFMaBiSmAd · December 11, 2010

A) You need to put the SID constant into those links as well (did you do a 'view source' of the page to see what you were getting?)

B) You need to turn off session.use_only_cookies as well.

C) Your session_name is apparently too long (at least on my system.)

D) Why aren't you using a cookie for the session id?

sorsha · December 11, 2010

I did do the page source and I saw the links had a session Id before you click on the letter. I tried putting the ".SID." in the link but ever where I seem to put it doesnt work.

The reason I am not using cookies was the project was that he gave us he did a couple of pages for us to use after the person is logged in, and I as using those as a model, but I cant seem to make it right with this page...

He did not do a very good job of teaching this in my opinion.

Pretty much look at my code for a different page and make it work with this one

sorsha · December 11, 2010

Im pretty sure its something to do with these lines of code but I dont know where to put the .SID.

if (strstr($words[$n], $alpha[$c])) {$links .= "\n$alpha[$c] "; }

{ $links .= "\n<A HREF=\"$self?letters=$alpha[$c]$letters&n=$n\">$alpha[$c]</A> "; }

PFMaBiSmAd · December 11, 2010

{ $links .= "\n<A HREF=\"$self?".SID."&letters=$alpha[$c]$letters&n=$n\">$alpha[$c]</A> "; }

sorsha · December 11, 2010

THank you thank YOU

When I had tried putting the code in there I had it before the ?

now it worked using the letters, but as soon as I hit play again it looses it again..do I have that in the wrong spot as well?

echo "<A HREF=$self?".SID."n=$n>Play again.</A> \n\n";

I also get this error printed out at the top of the screen

Warning: session_start() [function.session-start]: The session id contains illegal characters, valid characters are a-z, A-Z, 0-9 and '-,' in /var/www/html/final/hangmanrev.php on line 8

PFMaBiSmAd · December 11, 2010

The other links correctly have the SID in them.

As to the error message, just read what it is telling you and someone already posted about it -

C) Your session_name is apparently too long (at least on my system.)
