    Hi,

    Warning: implode() [function.implode]: Bad arguments. in /home/grisen/public_html/ATutor/groups.php on line 25


    Warning: mysql_fetch_assoc(): supplied argument is not a valid MySQL result resource in /home/grisen/public_html/ATutor/groups.php on line 31

    Re: Group problem

    Please try a nightly build from here: http://atutor.ca/atutor/builds/ATutor-snap_2006_10_18.tar.gz


  • 2006-10-20 04:54:09

    Re: Group problem

    Im sorry, it doesnt help with that nightly build. The strange error comes up...
    There should be more people out there having the same problem?

    Apreciate all kind of tips!

    regards


  • 2006-10-20 11:02:59

    Re: Group problem

    Did you re-install ATutor using the nightly build?

    Are you using a language other than English?

    Does this error appear as an instructor or as a student?


  • 2006-10-23 04:32:56

    Re:Implode problem

    Hi again!

    1. Yes, i re-installed ATutor using the nightly build.

    2. I only used English while testing this nightly build.

    3. This error (implode ....) appear both as instructor and as student.

    Im lost...

    Re:Implode problem

    ..when i change line 95 in links/index.php like this:
    from:
    //get links
    $groups = implode(',', $_SESSION['groups']);

    to:

    //get links
    $groups = ($_SESSION['groups']);

    it works, but yes, i know, thats not the way to solve it correct..

    register globals

    do you have register globals enabled?


  • 2006-10-24 06:26:27

    Re: register globals

    Are there any students registered for the class? If so yu go to manage groups. Then using the members link you find the students you want in the group and add them using the button meunu.

    Re: register globals

    register_argc_argv On On
    report_memleaks On On
    safe_mode Off Off
    [b]register_globals On On [/b]

    ..so they are enabled and set to ON...


  • 2006-10-24 11:08:26

    Re: register globals

    Try disabling register globals and letting us know if that fixes the problem.

    Re: register globals

    When i have register_globals off in .htaccess, i get internal server error.

    I have my site on a host and can not change in php.ini.

    Suggestions?

    Re: register globals

    Re: register globals

    Hi once again,
    It think the problem is solved.

    ATutor works om my local linux slackware, without errors so far.
    Here is register globals off by default.

    So now i wonder how to turn them off at my host. I tried to put a line in .htaccess, but get Internal server error...

    Someone has an idea?

    Thanks in advance


  • 2006-10-26 14:59:34

    Re: register globals

    You should probably ask your host to do that for you.


  • 2006-10-27 06:53:36

    Re: register globals

    Hi again,

    I think i have solved the problem getting register globals off.
    The host provider has register globals on as default, and recommend me to put a php.ini -file with "register globals off" in all folders using the register script. The errors disapeared !

    So i hope this is a good way to solve the problem..

    /Thank you
