The following should work okay for you:
<?php
if ((!$username) || (!$password)) {
header("Location: blah");
exit;
}
$userc = @mysql_connect("blah", "bleck", "bleep") or die("No DB
Connection");
@mysql_select_db("notgonnadoit", $userc) or die("No DB Select");
if (($userq = @mysql_query("SELECT name_first FROM guess WHERE username='$username'
AND password=PASSWORD('$password')",
$userc)) && (@mysql_num_rows($userq) == 1)) {
$namef = @mysql_result($userq, 0, 0);
echo "Welcome $namef";
} else {
header("Location: blah");
exit;
}
@mysql_close($userc);
?>
