Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in /usr/www/users/shafey7s/clients/header.php on line 9
Any reason why
this is the header file
<?PHP
include("../config.php");
function auth_user($username, $password) {
global $default_dbname;
$link_id = db_connect($default_dbname);
$query = "SELECT username from clients where username='$username and password = password('$password')";
$result = mysql_query($query);
if(!mysql_num_rows($result)) return 0;
else {
$query_data = mysql_fetch_row($result);
return $query_data[0];
}
}
session_start();
if (!isset($username)){
loginform();
exit;
}else{
session_register("username", "password");
$username = auth_user($username, $password);
if(!$username){
session_unregister("username");
session_unregister("password");
echo'Login Failed. You must enter a username and password combo. Please click <a href="../client.php">here</a> to try again.<br />';
exit;
}
else{
$text="Welcome $username!";
exit;
}
}
$today = date("F j, Y");
