Ok, strcmp so...

• At the top of your script, out of any Callback:
  
  pawn Код:

  new bool:BlockCommands;

• Block Command:
  
  pawn Код:

  if( !strcmp( cmdtext, "/blockcommands", true ) )
  {
      BlockCommands = true;
      SendClientMessage( playerid, -1, "You have blocked commands to all players." );
      SendClientMessage( playerid, -1, "Use {C0C0C0}/unblockcommands {FFFFFF}to unblock them." );
  
      return 1;
  }

• Unblock Command:
  
  pawn Код:

  if( !strcmp( cmdtext, "/unblockcommands", true ) )
  {
      BlockCommands = false;
      SendClientMessage( playerid, -1, "You have unblocked commands to all players." );
      SendClientMessage( playerid, -1, "Use {C0C0C0}/blockcommands {FFFFFF}to block them." );
  
      return 1;
  }

• Put at the top of the OnPlayerCommandText Callback:
  
  pawn Код:

  if( BlockCommands && !IsPlayerAdmin( playerid ) ) return SendClientMessage( playerid, -1, "You can't use commands because an Admin disabled them." );

PS: You must change IsPlayerAdmin with your Admin Variable and add to the commands too...
