Untested... Also this is without params, so you cannot get your own text, but you can change that.

pawn Код:

if (strcmp(cmdtext, "/setplate", true) == 0)
{
    new vehicleid;//Since it's not defined under OnPlayerCommandText
    vehicleid = GetPlayerVehicleID(playerid);//So that it actually gets the vehicleid
    if(pInfo[playerid][pDonateRank] < 1) return SendClientMessage(playerid, COLOR, "You're not a VIP");//I am guessing you are using pInfo
    SetVehicleNumberPlate(vehicleid, "Hi");//Setting the plate to "Hi"
    return 1;
}
