Use SetPVarString to temporarily store the player's name before setting the tag when they go AFK.

Something like:

Under your AFK code

PHP код:

SetPVarString(playerid, "AFKName", Name); 


And under /stopafk command

PHP код:

new name[24];
GetPVarString(playerid, "AFKName", name, sizeof(name));
SetPlayerName(playerid, name);
DeletePVar(playerid, "AFKName"); 


It's better if you use global arrays but PVar is easier to use so.
