1) You can do something like this to get player name and add [Admin] to the front of it.

pawn Код:

if(PlayerInfo[playerid][pAdmin] >= 1) //Change to your admin variable
{
    new pname[MAX_PLAYER_NAME], string[128];
    GetPlayerName(playerid, pname, sizeof(pname));
    format(string, sizeof(string), "[Admin] %s", pname);
    SetPlayerName(playerid, string);
}

This simply states you create two variables, string and pname. pname receives the players name, then formats it into a string after the [Admin] name in front of it. Then it simply sets the name to the string.

Untested, but it's worth a shot.

Not quite sure how to do the second thing.

You could try to use strfind.

pawn Код:

new pname[MAX_PLAYER_NAME];
GetPlayerName(playerid, pname, sizeof(pname));
if(strfind(pname, "[Admin]", true) != -1)
{
    if(!PlayerInfo[playerid][pAdmin] >= 1) //Again,change to your admin variable
    {
        Kick(playerid);
        SendClientMessage(playerid, -1, "Please remove the [Admin] in your name, as you are not an admin");
        return 1;
    }
}

Never used something like this but if not correct, this would check the pname for [Admin] in it and would return with a kick and a sendclientmessage if he isn't an admin. If he is, it would continue.
