gametext crashing - Annihalation - 20.07.2009

So I made a code for the business ownership part of my server, the code is called "/setentrysign".

the entrances are marked by fast-respawn pickups in my server, and when you walk over one, it displays the store's "entrysign" (as gametext)

so far, I have the entire thing working. The only problem is if someone uses a "~n~", or an underscore (_), the server crashes. Is there a way to make it to where it will refuse the input if the server finds a "~n~"?

however, I want to make it to where (for this particular code only), the server converts all _'s into spaces. Example would be "/setentrysign Pizza_Palace". When someone picked that up, they would get "Pizza Palace"

Heres the code for the command, and thanks in advance

Код:

	if(strcmp(cmd, "/setentrysign", true)==0)
	{
	  new tmp[128], interior;
	  tmp = strtok(cmdtext, idx);
	  interior = GetPlayerInterior(playerid);
	  
	  if (strlen(tmp)==0) return SendClientMessage(playerid, 0xFF0000AA, "USAGE: /setentrysign <text>");
	  
	  if (interior ==0) return SendClientMessage(playerid, 0xFF0000AA, "You must be inside a business you own to use this");
	  
	  if (interior == 5)
	  {
	    new pname[24], cowner[256];
	    GetPlayerName(playerid, pname, sizeof(pname));
	    cowner = dini_Get("pizzaria.ini", "owner");
	    if (cowner = pname)
     	{
	      new string[256];
	      format(string, sizeof(string), "New Business Entry Sign: %s", tmp);
	      dini_Set("pizzaria.ini", "entrysign", tmp);
				SendClientMessage(playerid, 0xFFFFFFFF, string);
			}
			else return SendClientMessage(playerid, 0xFF0000AA, "ERROR: You do not own this business");
		}
	}

p.s. I know I know bad me, I used strtok :P

Just a guess:
dini uses en/uncode(), will it make something wrong?

Actually, you shouldn't let the users put the ~ in text draws. Ever. So do this:

pawn Код:

if (strfind(tmp, "~", true) >= 0)
{
  // invalid character, send evil error message here
}
