    I'm crazy, why php doesn't transfer variable submitted by web form?

    I had previously installed php-4.3.9 and apache-2.0.49 on my solaris9
    server and written a php script for user login, it ran well until
    today...:-(
    today for some reasons I upgraded php to php-5.1.2, complied as
    apache's DSO module, and I found the script couldn't work when being
    accessed by IE. I didn't know why...It seemed php script hadn't
    transfered variables submmitted by web form to itself...now the
    following is my script:


    <?php
    if ($queryflag == 1) {
    $ybn="admin";
    $ybp="111";
    $ybusername=$_P OST["username"];
    $ybuserpwd=$_PO ST["password"];
    if ($ybusername==$ ybn AND $ybuserpwd==$yb p){
    session_start() ;
    $_SESSION["admin"]=true;
    header("locatio n: testtest.php");
    } else {
    echo <<<EOM
    <html>
    <head>
    <meta http-equiv="Content-Type" content="text/html; charset=gb2312" >
    <title>login</title>

    ..style7 {
    font-size: 14px;
    color: #FF0000;
    }
    -->
    </style>
    </head>

      well, you probably had register_global s On before, and php-5.1.2
      changed it to off.

      PHP: Description of core php.ini directives - Manual
      http://es.php.net/register_globals
      Description of core php.ini directives


      just substitute $queryflag for $_POST['queryflag'] and everything
      should work again

          Hi Juan,

          That was my first guess too, but futheron in the same script he is using the
          $_POST to retrieve variables from the posting.

          Maybe the coder changed his/her mind halfway the script. :-)

              I concur.
