You didn't post any html form information so I think you could start there. > $username = $_POST['username']; > $password = $_POST['password']; > > if ($username&&$password) > > { > $connect = mysql_connect("localhost", "tutor_root", "admin") or > die("couldn't connect"); > mysql_select_db("tutor_register") or die("couldn't find db"); > > > $query = mysql_query("SELECT * FROM register WHERE username ='$username'"); > $numrows = mysql_num_rows($query); > if ($numrows!=1) > > { > //code to login > > while ($row =mysql_fetch_assoc($query)) > { > $dbusername = $row['username']; > $dbpassword= $row['password']; > > } > //check to see if they match > > if ($username==$dbusername&&$password==$dbpassword) > { > echo "you are in <a href='member.php'>click</a> here to enter the members > page"; > > > $_SESSION['username']=$username; > > } > else > > echo "incorrect password"; > } > else > > die("That user dosen't exist"); > > > } > else > die("pelase enter a username and a password"); > > > > ?> > > -- Jason Gerfen Systems Administration/Web application development jason.gerfen@...

	Re: Need help with the code by Jason Gerfen-2 :: Rate this Message: Reply to Author \| View Threaded \| Show Only this Message Add this to your script and just copy and paste it back. Seriously, you are not going to get any help if you don't show anyone the output of your problem. echo "<pre>"; var_dump(print_r($_GET)); var_dump(print_r($_POST)); echo "</pre>"; If you are not getting anything in the post try changing the method of your html form to 'get' vs. 'post' *IE: <form method="get" action="mem_login.php"> And copy and paste the results so we can see where the problem is. If you are feeling weird about an authentication script contents then filter the data but don't just leave out parts of the output. nagendra prasad wrote: > Yes I did but still its not working on my web server however its > working fine with my WAMP server locally. > > > > On Fri, Oct 2, 2009 at 9:17 PM, Jason Gerfen > <jason.gerfen@... <mailto:jason.gerfen@...>> wrote: > > nagendra prasad wrote: > > OK so here is the form for the below code: > > <html> > > <form action='mem_login.php' method='POST'> > Username: <input type='text' name='username'><br> > Password: <input type='password' name='password'><br> > <input type='submit' value='Log in'> > </form> > </html> > > Did you try looking at the $_POST array data? > > > echo var_dump(print_r($_POST)); > > > -- > Jason Gerfen > Systems Administration/Web application development > jason.gerfen@... <mailto:jason.gerfen@...> > > Marriott Library > Lab Systems PC > 295 South 1500 East > Salt Lake City, Utah 84112-0806 > Ext 5-9810 > > > > > -- > Guru Prasad > Ubuntu Voice GTK+ Forum -- Jason Gerfen Systems Administration/Web application development jason.gerfen@...
