Switch needed for triggerserver?

[Schetti]

Do I need a switch command for triggerserver?
I tried to check the command via if-funktion, but that didn't work, can someone tell me why?

PHP Code:

function onActionserverside() 
{
   if (params[0] == "summon")   //If instead of a switch
   {
      temp.pl = findplayerbycommunityname(params[1]);
      if (pl != NULL) 
      {
       pl.setlevel2(player.level, player.x, player.y);
       pl.chat = format("", player.account);
       player.chat = format("", pl.communityname);
      }else
    player.chat = format("Community name '%s' not found!", params[1]);
   }
}
//#CLIENTSIDE
function onPlayerChats() 
{
   if (player.chat.starts("/summon") && player.account != NULL) 
   {
    triggerserver("gui", this.name, "summon", player.chat.substring(8));
   }
}
