Hello Everyone, Can you help me with this code? Spoiler PHP: }elseif($args[0] === "tp" and $sender->hasPermission("pet.cmd.tp")) { if($sender instanceof Player); if($args[1] === null and $args[2] !== null) { $sender->sendMessage(TF::GREEN."Pet Teleporting..."); $pet->teleport($sender->getPosition()); $sender->sendMessage(TF::GREEN."Pet Teleported!"); // $sender->sendMessage(TF::RED."Functionality not implemented yet"); return true; } return true; } return false; } return false; }
You didn't tell us the lines it was occurring at.. But that error usually means you're trying to access an array index that doesn't exist.

See what the others have been telling you... Use isset() to check if an index exists; use empty() to check if an index exists and also whether the value of the array index can evaluate to being 'true'. Since you want to check if the variable is also equal to "", you might want to use empty(). When you do something like ($args[99] == null), PHP will immediately check if index '99' exists, before evaluating your statement. When it doesn't exist, it will return an error to you. Checking the size of $args is also something you can do. So instead of using PHP: if($args[1] === "" or $args[1] === null) You'd use: PHP: if(empty($args[1])) or if (sizeof($args) == 1)
