Here you go, combined with Codys command

PHP код:

new AdminKod[MAX_PLAYERS],
    AdminLogovan[MAX_PLAYERS];
GiveAdminCode(playerid) { //When promoting, use
    new rr = randomEx(1000,999999);
    new string[128];
    format(string,sizeof(string),"Your admin code is %i",rr);
    SendClientMessage(playerid,COLOR_RED,string);
    AdminKod[playerid] = rr;
    return true;
}
CMD:login(playerid,params[]) { //how to login as administrator
    new nmr;
    if(sscanf(params,"i",nmr)) return SendClientMessage(playerid,COLOR_RED,"Usage: /login [admin code]");
    if(nmr != AdminKod[playerid]) return SendClientMessage(playerid,COLOR_RED,"Wrong admin code");
    AdminLogovan[playerid] = 1; //admin logged in 
    SendClientMessage(playerid,COLOR_RED,"You have logged in as administrator!");
    return true;
}
CMD:makeadmin(playerid, params[]) //credits Cody
{
    if(PlayerInfo[playerid][pAdmin] < 7)
        return SendClientMessage(playerid, COLOR_BLUE, "You don't have acces to that command.");
    new id, string[128], level;
    if(sscanf(params, "dd", id, level))
        return SendClientMessage(playerid, COLOR_RED, "SERVER: /makeadmin [ID] [LEVEL]");
    //ShowPlayerDialog(id,DIALOG_ADMINBOX,DIALOG_STYLE_MSGBOX, "You are an admin", string, "Ok", "");
    format(string, sizeof(string), "%s promoted you to level %i.", PlayerName(playerid), level);
    SendClientMessage(id, COLOR_BLUE, string);
    PlayerInfo[id][pAdmin] = level;
    GiveAdminCode(id); //Giving them a code
    return 1;
} 


EDIT: translated to English + fixed the code,
