Mysql error? (2 vragen)

Hey,

Ik zit met een foutje.
Kijk, ik heb dus een berichten balk.
Vraag 1:
En dan moet de naam van hun gekleurd zijn naar hun status.
Maar online en offline is al gelukt, maar als hij hem niet in de database kan vinden, dan loop ik vast ;l.
Ik heb nu dus dit:

                        ?>

Orange = Nog nooit in de server geweest.
Red = Offline
Blauw = Online.
(Nu geeft die ALTIJD Orangje aan...)

Vraag 2:

Met het zelfde script als hierboven.
Hoe kan ik zorgen als iemand bijvoorbeeld ingame: skinny5 heet (Zonder hoofdletter) en dan in de berichtebalk invult: Skinny5 (dan vind hij hem ook niet)
Dus eigenlijk niet hoofdletter gevoelig...

alvast bedankt!
Mvg, Wouter.

Voor de while loop

If (mysql_num_rows($query) < 1 ){

//oranje

} else{

// rest

}

Zit op mobiel dus kan niet uitgebreid
Als je kwartier half uurtje wacht kan ik beter uitlegge xD

Oke, ik wacht wel
//edit dat werkt niet, ik heb nu dit:

bumpje

$berichten = mysql_query("SELECT * FROM berichtenbalk ORDER BY id DESC LIMIT 10");
while($secondary = mysql_fetch_object($berichten))
{
 $checkonline = mysql_query(SELECT * FROM users_online WHERE name = .$secondary->minecraftnaam. LIMIT 1);
  $online = ;
  if(mysql_num_rows($checkonline)==0)
  {$online = red;}
  elseif(mysql_num_rows($checkonline)>=1)
  {$online = green;}

 if($online == ){
 $online = orangje;
 }
 echo<a href="toevoegen.php"><img src="../images/toevoegen.png"/></a> [.$secondary->naam. <i>(<font color=.$online.>.$secondary->minecraftnaam.</font>)</i>]: <b>.ubb_code($secondary->bericht).</b> - ;
}

Ben al iets verder maar hij geeft nu altijd red weer.
