That little part basically means if $count echos any number under 0, then log the user in

still didnt work

 

We prevented a bug that may occur in the future, so lets give a pat on our backs. You should print out the username and password from the FORM, and the DB and see if they equal each other...

 

<?php
$host="localhost"; // Host name 
$username="pacifij1_blue"; // Mysql username 
$password="8336994895"; // Mysql password 
$db_name="pacifij1_blue"; // Database name 


// Connect to server and select databse.
mysql_connect("$host", "$username", "$password")or die("cannot connect"); 
mysql_select_db("$db_name")or die("cannot select DB");

// username and password sent from signup form 
$callsign = $_POST['callsign']; 
$pwd = $_POST['pwd']; 
$first_name = $_POST['first_name']; 
$last_name = $_POST['last_name']; 


$sql="SELECT * FROM pilot WHERE callsign='$callsign' and pwd='$pwd'";
$result=mysql_query($sql) or die(mysql_error());

// Mysql_num_row is counting table row
$count=mysql_num_rows($result);
// If result matched $myusername and $mypassword, table row must be 1 row
$row = mysql_fetch_array($result);

echo 'Username Tried: ' .$callsign;
echo 'Password Tried: ' .$pwd.'<br>';

echo 'Username DB: ' .$row['pwd'];
echo 'Password DB: ' .$row['callsign'].'<br>';


if($count > 0){
// Register $myusername, $mypassword and redirect to file "login_success.php"
session_register("callsign");
session_register("pwd"); 
session_register("first_name"); 
session_register("last_name"); 
header("location:login_success.php");
echo 'Login Worked';
}
else {
mysql_error();
echo 'Login Didnt Work';
}
?>

i don't bother with counts..

 

i just would do...

 

 

$sql="SELECT `id` FROM pilot WHERE callsign='$callsign' and pwd='$pwd'";

$result=mysql_query($sql) or die(mysql_error());

$id= mysql_fetch_array($result);

 

if(empty($id['id'])){

echo failed}

 

if(strlen($id['id']) > 0){

log in

}

 

it doesn't count rows... so if there was more than 1 password and username the same i'd be screwed... but i check for existing user names at registration, so that shouldn't be a problem

You would prevent that at the registration process, and your method takes a lifetime
