Quick session question
in [General]

From: Danny on 24 Jun 2010 10:24 Hi guys, I always start new projects with the following session code-snippet: (In other words this is how I initialize my sessions in the index.php file.) ### START CODE SNIPPET ######################################################## <?php session_start(); setcookie(session_name(),"",0,"/"); unset($_COOKIE[session_name()]); $_SESSION = array(); session_unset(); session_destroy(); session_start(); /// Define some $_SESSION variables $_SESSION['sessionid'] = session_id() ; $_SESSION['server'] = "http://localhost/~user/new_project" ; $_SESSION['sql_dflts'] = $_SESSION['server']."/sql/sql_dflts.inc" ; $_SESSION['remoteaddr'] = $_SERVER['REMOTE_ADDR'] ; $_SESSION['remotehost'] = gethostbyaddr ( $_SERVER['REMOTE_ADDR'] ) ; /// Include Files include ( $_SESSION['sql_dflts'] ) ; include ( $_SESSION['server']."/fnc/fnc_include_dir.inc" ) ; $var_include_dir = include_dir ( "fnc" ) ; ?> ### END CODE SNIPPET ######################################################### All of the projects I have done so far were for business intranet purposes and it worked fine. But last week I uploaded another project to the internet and my sessions did not work. I have been using it this way since v4.0 (I think, anyway since a LONG time ago), but now I think it is a bit outdated and needs some kind of revision. Is this still sufficient or can you guys give some tips on a more "updated" way of starting my sessions? My php.ini file is stock-standard. I am running version 5.2.6-1 with apache 2.2.9 on a Debian 5.04 machine. Thank You Danny

Generally these functions are only used if you are closing the session. When you say 'sessions did not work' what do you mean? Sessions aren't being created? You can't access session variables? You need to be a bit more specific about the issue. Thanks, Ash http://www.ashleysheridan.co.uk

The problem is more the likely the calls to include a remote file. Basically, to expand your variables out, you would be doing this: include ( 'http://localhost/~user/new_project/sql/sql_dflts.inc' ) ; include ( 'http://localhost/~user/new_project/fnc/fnc_include_dir.inc' ) ; If your php.ini settings are stock, then the problem is with the allow_url_include directive. It is set to "0" by default. See here: http://us3.php.net/manual/en/filesystem.configuration.php Change that setting to '1' and restart your web server, then you should be good to go. > > Thank You > > Danny > -- Jim Lucas A: Maybe because some people are too annoyed by top-posting. Q: Why do I not get an answer to my question(s)? A: Because it messes up the order in which people normally read text. Q: Why is top-posting such a bad thing?

Sorry, here is an explanation: The project I uploaded for a customer is a "stock ordering" web-app that they used on their local intranet for a year or so, but now they want this same web-app to be available globally. I thought that it would work "out-the-box" on the internet but it doesn't. On their local-lan I am able to do some (advanced) login checks with sessions with no problem, like I said, it has been workng for a year or so now. Also, the same login sequence I use here I also use in my other intranet web-apps. However, when I uploaded this project and I log on, I just get a blank screen after the login checks are done and it is supposed to take me to the logged-in start page. That is why I say that somehow my sessions are not "carried over" or "caught" by php. Thanks for the comments on my session initialization, if there is not really anything that should be changed, then I will leave it like it is. Just one more thing, should I always expand the URL's to an absolute path instead of using a session variable like I do? Thnks again guys Danny
