    Session variable reading doesn't work

    L.S.

    I am developing a PHP-login script (on Lycos Tripod) that uses Session to
    pass on variables. Below is the entire (stripped) structure that I use. It
    opens a page where you can Set and Read the session variable BUT ... It
    doesn't work!!! It seems that both set- and readlink open their own private
    session.

    How can I get the read-link to access the proper session variable?

    Below is a full testing environment. It uses frames and should work fine ...
    but it doesn't. I use this directory-structure:
    testindex.php
    testmenu.php
    testhome.php
    login001 [dir]
    -----testsetvar.php
    -----testreadvar.php
    fb001 [dir]
    -----testfb.php
    -----testframe1.php
    -----testframe2.php

    The content of the files is:

      I might be wrong, but first off is it that you have to register testvar
      after you've actually declared it? As I say I may be way off there.

      The other thing is to check if you've got register_global s on in your
      php.ini file.

      If it's off (which is the default IIRC) then the above won't work.
      Alternatively, just use $_SESSION["testvar"] = "this is the testvariable";

      With the $_SESSION[] array, you do not need to use session_registe r.

      If I used session_registe r with register_global s off, I got error messages
      and things didn't work as planned.

      using $_SESSION is quicker anyway, because you can just treat it like you
      might $testvar but without having to bother with another function
      (session_regist er) everytime.

          that's the point ... but as you said, it's better to use $_SESSION['var']
          anyway ...

              Re: Session variable reading doesn't work

              I removed the references to session_start() and session_is_regi stered() and
              replaced them with the $_SESSION way of setting and reading the variable but
              .... ALAS it still doesn't work. Any other ideas?

              Thanks for your replies anyway, Peter.

                  Re: Jippie .. Session variable reading does work

                  I finally got it working. I went back to the original code, using
                  session_start() etc. Nathan was right!! Apparantly, you must first declare
                  the variable and then make a call to session_registe r().

                  Thank you all for your replies.

                  Peter.
