this page is calling validate.php which is :

[PHP]<?php
session_start() ;
$passwords = array("ajohari" =>"anurag",

"pkk" =>"kalra",

<?
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'];

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.

Mimicking a global variable
by: Animesh K | last post by:
Hello All: I want to have some re-usable variables, which can be used inside (as well as outside) objects. The use of GLOBALS array is one option, but then I will have to keep track of "reserved variable names" elsewhere. Another option is to declare a $FORALL array in an abstract class and initialize it. And then define every object as an extension of this abstract class.

The easy way to turn off automatic updates for Windows 10/11

Overview: Windows 11 and 10 have less user interface control over operating system update behaviour than previous versions of Windows. In Windows 11 and 10, there is no way to turn off the Windows Update option using the Control Panel or Settings app; it automatically checks for updates and installs any it finds, whether you like it or not. For most users, this new feature is actually very convenient. If you want to control the update process,...
