Hey, I'm trying to use a tutorial to make a login for my website using this tutorial: http://www.phpeasyst...om/phptu/6.html I'm getting the following error when I try to login:Warning: mysql_connect() [function.mysql-connect]: Access denied for user 'ODBC'@'localhost' (using password: NO) in C:\.........................\www\login.php on line 9cannot connect The fat underlined line is line 9 ;)This is the code I am using:

<?php
$host="localhost"; //
$username="root"; //
$password=""; //
$db_name="westpop"; //
$tbl_name="leden"; //
mysql_connect("$host", "$username", "$password")or die("cannot connect");
mysql_select_db("$db_name")or die("cannot select DB");
$myusername=$_POST['myusername'];
$mypassword=$_POST['mypassword'];
$count=mysql_num_rows($result);
if($count==1){
session_register("myusername");
session_register("mypassword");
header("location:login_succes.php");
}
else {
echo "Wrong Username or Password";
}
?>
Anyone able to tell me what i do wrong? Thanks in advance! Porkypie Edited by porkypie

Thanks for the help. It seems something else is wrong with my code. When i try to log in now i get the following message: Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in C:\.........................\www\login.php on line 15Wrong Username or Password. This is line 15:$count=mysql_num_rows($result); how do i fix my problem this time? Porkypie

For one you haven't got a query. You're not checking the input against any records. You're also passing $result to mysql_num_rows(), which hasn't been set. Try something like:

$host="localhost"; //$username="root"; //$password=""; //$db_name="westpop"; //$tbl_name="leden"; // mysql_connect($host, $username, $password)or die("cannot connect");mysql_select_db($db_name)or die("cannot select DB"); $myusername=$_POST['myusername'];$mypassword=$_POST['mypassword']; $result = mysql_query("SELECT * FROM $tbl_name WHERE username='{$myusername}' AND password='{$mypassword}'"); $count=mysql_num_rows($result); if($count==1){ session_register("myusername"); session_register("mypassword"); header("location:login_succes.php"); } else { echo "Wrong Username or Password"; }

This is assuming your table field for the username and pass is 'username' and 'password'. If it isn't just change the query to suit the table field names. Regards, Lab.
