    variable cannot be passed to multiple pages.

    i have designed a login page like this:

    [HTML]<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"
    "http://www.w3.org/TR/html4/loose.dtd">
    <html>
    <head>

    <style type="text/css">
    <!--

    .style2 {font-size: 14px}
    .style3 {font-size: 18px}
    .style4 {font-size: 24px}
    .style5 {font-size: 36px}
    -->
    </style>
    </head>

    <body bgcolor="#99CCF F">
    <form name="form1" method="post" action="../myphp/validate1.php">
    <div align="center">
    <p> <span class="style1">

    <pre><span class="style1"> <span class="style2"> <span class="style3"> <span class="style4"> <span class="style5"> <label><u>Elect rical Engineering Department IIT-KANPUR</u></label></span></span></span></span></span></pre>
    <p>&nbsp;</p>
    <p><span class="style1"> </span> </p>
    <p>&nbsp;</p>
    <p>&nbsp;</p>
    <p>&nbsp;</p>
    <table width="38%" border="0">
    <tr>
    <th scope="row"><di v align="left">

    &nbsp;</div></th>
    <td><input name="username" type="text" size="35" maxlength="35"> </td>
    </tr>
    <tr>
    <th height="29" scope="row"><di v align="left">Pa ssword</div></th>
    <td><input name="password" type="password" size="35" maxlength="35"> </td>
    </tr>
    </table>
    &nbsp;&nbsp;&nb sp;&nbsp;&nbsp; &nbsp;&nbsp;&nb sp;&nbsp;&nbsp; &nbsp;
    <p>&nbsp;</p>
    <table width="2%" border="0" align="center">
    <tr>
    <th scope="row"><in put type="submit" name="Submit" value="Login"></th>
    <td><input type="submit" name="Submit2" value="Cancel"> </td>
    </tr>
    </table>
    <p>&nbsp;</p>

    <label><u><stro ng></strong></u></label>
    </p>
    </div>
    </form>
    </body>
    </html>[/HTML]

    this page is calling validate.php which is :

    [PHP]<?php
    session_start() ;
    $passwords = array("ajohari" =>"anurag",
    "knaveen" =>"naveen",
    "pkk" =>"kalra",
    "anu" =>"anu");
    if ($password == $passwords[$username]){
    $_SESSION['user']=$username?>
    <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Frameset//EN" "http://www.w3.org/TR/html4/frameset.dtd">
    <html>
    <head>
    <title>Faculy Information of E.E Depatment</title>
    <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1">
    </head>

    <frameset rows="144,*" cols="*" frameborder="NO " border="0" framespacing="0 ">
    <frame src="frame1.php " name="topFrame" scrolling="NO" noresize >
    <frameset rows="*" cols="257,*" framespacing="0 " frameborder="NO " border="0">
    <frame src="frame2.php " name="leftFrame " scrolling="NO" noresize>
    <frame src="frame3.php " name="mainFrame ">
    </frameset>
    </frameset>
    </html>
    <?
    exit();
    }else{
    echo "<H2>Invali d user name or password: access denied.</H2>";
    include("../myphp/eeiitk.php");
    }
    ?>[/PHP]

    after validating frame3.php page is called which is:

    [PHP] <?php
    session_start() ;
    $connection = pg_connect("hos t=localhost dbname=personal user=postgres") ;
    if (!$connection) {
    print("Connecti on Failed.");
    exit;
    }
    $username1=$_SE SSION['user'];

    $myresult = pg_exec($connec tion, "SELECT * FROM personal where username='usern ame1'");

    for ($lt = 0; $lt < pg_numrows($myr esult); $lt++) {
    $name = pg_result($myre sult, $lt, 0);
    $designation = pg_result($myre sult, $lt, 1);
    $department = pg_result($myre sult, $lt, 2);
    $telephonework = pg_result($myre sult, $lt, 3);
    $telephoneres = pg_result($myre sult, $lt, 4);
    $fax = pg_result($myre sult, $lt, 5);
    $email = pg_result($myre sult, $lt, 6);
    $address = pg_result($myre sult, $lt, 7);
    $areaofinterest = pg_result($myre sult, $lt, 8);
    $username= pg_result($myre sult, $lt, 9);
    $image= pg_result($myre sult, $lt, 10);
    }
    ?>

      Oh yes, these variables can, and indeed are, passed to the script. But you have not assigned the passed POSTed values for username and password the the appropriate variables.

      Script validate.php must begin as follows:

      [php]<?php
      session_start() ;
      $username = trim(strip_tags ($_POST['username']));
      $password = trim(strip_tags ($_POST['password']));
      // ... etc ...[/php]

              I am sure it works but somehow you don't handle the POSTed values not correctly. Show the code.
