    Sessions 2

    Hello,

    I tried to upload in my website the following trial php file:

    <FORM METHOD="POST" ACTION="prova.p hp">
    <b>Combinatio n</b><br><br>
    Element 1: <INPUT NAME="el1" TYPE="TEXT">
    <BR>
    Element 2: <INPUT NAME="el2" TYPE="TEXT">
    <br>
    <INPUT TYPE="SUBMIT" VALUE"Submit">
    </FORM>
    <br>
    Combination<br> <br>
    <?php

    session_start() ;
    $_SESSION["combinatio ns"][] = ($_REQUEST["el1"].$_REQUEST["el2"]);
    print_r($_SESSI ON["combinatio ns"]);
    ?>

    As result, I obtain the following error:

    Warning: session_start() [function.sessio n-start]: Cannot send session
    cookie - headers already sent by (output started at
    /home/httpd/docs/prova.php:12) in /home/httpd/docs/prova.php on line 13

    Warning: session_start() [function.sessio n-start]: Cannot send session
    cache limiter - headers already sent (output started at
    /home/httpd/docs/prova.php:12) in /home/httpd/docs/prova.php on line 13

    Sessions don't work.
    Can you help me to understand which is the problem and how can I solve
    it please?
    Many thanks.

    Cheers,
    Nico

      Re: Sessions 2

      hello nico,

      this error comes when you send anything to browser before starting
      session. this happens with any header function you may use. to solve
      this you must put "session_start( )" at the start of php the page as i
      had shown you in your the previous post.

      this will solve your problem.

      cheers
      Amit
