Hi there,

I've tried several time to create my login page but I still got an error. F.Y.I I my login form is login.html and login result is login.php


Warning: Supplied argument is not a valid MySQL result resource in C:\apache\htdocs\researchers\login.php on line 132

Warning: Cannot add header information - headers already sent by (output started at C:\apache\htdocs\researchers\login.php:17) in C:\apache\htdocs\researchers\login.php on line 135

This is my code for "login.php" that I obtained from a PHP book

Code: Select all

define ('HOST', 'localhost');
define ('USER', '');
define ('PASS', '');
define ('DB', 'researchers');

//connect to the database  and get numfound

mysql_connect(HOST, USER, PASS);


$result = mysql_query("SELECT COUNT (*) AS numfound FROM maintable WHERE username='{$HTTP_POST_VARS['username']}' AND pass='{$HTTP_POST_VARS['pass']}'");

$result_ar = mysql_fetch_array($result);
if ($result_ar['numfound'] < 1)
   header( 'Location: loginform.php?error=1' );
   echo "Logged in successfully";


My question:
i)Page that user can enter their username and password then press 'Submit' should be ".html" or ".php"?

ii)How do I add restrict to several pages that only logged in user can access for example update, upload and rate page. I want to do this to avoid user bypass the login page by typing the directory to the restricted page.
So that when they try to bypass, they will be directed to login page.

iii)Do I need to configure php.ini file, if yes, how?

Thanks in advance
Thanks and regards;

$result = mysql_query("SELECT COUNT(*) AS numfound FROM maintable WHERE username='$_POST[username]' AND pass='$_POST[pass]'") or die (mysql_error());

what erorr you get????

1) mo mater, file.extension - must be extension of php script
2) set him a cookie
3) if you have thi error, it means that php workable at your server...
