    POST, GET and variables ?

    Hello,


    As beginner, I'm a bit confused by passing 2 variables using a html-form
    with method=POST. If passing one of them, it works ; if passing both
    together, nope. At least when I reload the same page by using
    $_SERVER["PHP_SELF"] in an included file (inc.php) it doesn't work.
    Referring to another "page.php" is succesfull. Also passing both variables
    with the GET-method works. Can somebody help me please ?
    Thank you,
    Dirk.

      Please post some code. The form itself would be quite helpful. What is
      the output of <?php print_r($_POST) ; ?>

          Thanks for your reply. If both input-text-fields were filled in, the
          output of print_r($_POST) is : Array ( )
          If only one input-text-field is filled in, output is : Array ( [email] =>
          mail [pass] =) or Array ( [email] =[pass] =password )
          Here is the code :

          <?php
          $dbh=mysql_conn ect("localhost" ,"user","pas s") or die("Can't connect to
          db!");
          mysql_select_db ("calendar") or die("Can't select db!");
          session_start() ;
          if (!$_SESSION["Login"]) {
          if ($_POST['email'] AND $_POST['pass']) {
          $Email=$_POST['email'];
          $Pass=$_POST['pass'];
          $mydb=mysql_que ry("SELECT ID from admin WHERE Email='$Email'
          and Pass= MD5('$Pass') LIMIT 1");
          if ($data=mysql_fe tch_array($mydb )) {
          $_SESSION["Login"]=$data["ID"];
          }
          $me=$_SERVER['PHP_SELF'];
          header("Locatio n: $me");
          exit;
          }
          print <<<EOL
          <head>
          <title>Admin Console</title>
          </head>
          <body>

          <h1>admin system</h1>
          <form action=
          EOL;
          echo $_SERVER["PHP_SELF"];
          print <<<EOL
          method=post>
          <p>Email<inpu t type=text name=email></p>
          <pPass<input type=password name=pass></p>
          <input type=submit>
          </form></body></html>
          EOL;
          die();

          }
          ?>

              Thanks for your reply. If both input-text-fields were filled in, the
              output of print_r($_POST) is : Array ( )
              If only one input-text-field is filled in, output is : Array ( [email] =>
              mail [pass] =) or Array ( [email] =[pass] =password )
              In both cases it should also contain the submit button, I'm guessing it
              defaults to "submit" ="submit" if no values are provided for name and
              value.
              Here is the code :
              >
              <?php
              $dbh=mysql_conn ect("localhost" ,"user","pas s") or die("Can't connect to
              db!");
              mysql_select_db ("calendar") or die("Can't select db!");
              session_start() ;
              if (!$_SESSION["Login"]) {
              if ($_POST['email'] AND $_POST['pass']) {
              $Email=$_POST['email'];
              $Pass=$_POST['pass'];
              $mydb=mysql_que ry("SELECT ID from admin WHERE Email='$Email'
              and Pass= MD5('$Pass') LIMIT 1");
              if ($data=mysql_fe tch_array($mydb )) {
              $_SESSION["Login"]=$data["ID"];
              }
              $me=$_SERVER['PHP_SELF'];
              header("Locatio n: $me");
              exit;
              Should the email and password match and the code reaches this point, the
              post data is lost. Ie. if the login is successful, you'll never see the
              result of the real print_r($_POST) because of the redirection. Humour me
              and run the test case so that a) the login crendentials you input are
              wrong so you don't log in and b) comment the header and exit lines so
              that you are not redirected to another page after successfull login.
              Then see the output.
              }
              print <<<EOL
              <head>
              <title>Admin Console</title>
              </head>
              <body>
              >
              <h1>admin system</h1>
              <form action=
              EOL;
              echo $_SERVER["PHP_SELF"];
              print <<<EOL
              method=post>
              <p>Email<inpu t type=text name=email></p>
              <pPass<input type=password name=pass></p>
              <input type=submit>
              </form></body></html>
              EOL;
              die();
              >
              }
              ?>
              Of course it never hurts to eliminate all other possible causes for
              failure, until you've narrowed it down to the real thing. Hence I
              suggest you clean the code, insert the quotemarks in right places and so on.

              Missing submit from $_POST is quite mysterious. The empty array() can be
              explained if the page is redirected. The test case should be the kind
              where there is absolutely nothing but a form and print_r to make sure
              there isn't anything else causing the data to be lost.
