Something like this will do:

pawn Код:

new str[128];
new plname[MAX_PLAYER_NAME];

GetPlayerName(playerid, plname, sizeof(plname));

format(str, sizeof(str), "Please register: %s!\nEnter your password to register:", plname);
ShowPlayerDialog(playerid, dialogid, DIALOG_STYLE_INPUT, "Login", str, "Register", "Leave");
