object empty inside calling function using pointer as argument - c++

Question

I am learning C++ with pointers and trying to program a small game. I have a class PlayerManager which should create players and save them in a file.
The code compiles but when I call the method savePlayer, the pointer inside the method is valid but I cannot access the object to which the pointer is pointing.
I have searched for similar problems on internet but did not find anything similar. I may not be looking for the right keywords as I have no idea where this comes from.
I checked before the function is called and the pointer is working and I can access the object.
Inside the calling function, the pointer still has the right address but I cannot access the object. Nothing is returned.
After the calling function the pointer is still valid and the object accessible. (see //Comments in the code below)
Here are my two functions inside my PlayerManager class.
void PlayerManager::createPlayer()
{
Player *playerPtr = new Player();
std::string name;
std::cout << "Name: ";
std::cin >> name; // I entered for instance John
std::cout << std::endl;
playerPtr->setName(name);
std::cout << "PlayerPtr name before savePlayer: " << playerPtr->getName() << std::endl; // Outputs John
std::cout << "playerPtr before savePlayer: " << playerPtr << std::endl; // Ouputs the address
this->savePlayer(playerPtr);
std::cout << "PlayerPtr name after savePlayer but inside createPlayer: " << playerPtr->getName() << std::endl; // Outputs: John
delete playerPtr;
}
void PlayerManager::savePlayer(Player* playerPtr) // the called method
{
std::cout << "playerPtr inside savePlayer: " << playerPtr << std::endl; // Outputs the address
std::cout << "PlayerPtr name inside savePlayer: " << playerPtr->getName() << std::endl; // Outputs nothing
std::string const fileName = "Players/"+playerPtr->getName()+".txt";
std::cout << fileName << std::endl; // Outputs Players/.txt
std::ofstream myFile = std::ofstream(fileName.c_str());
if(myFile)
{
std::cout << "Enregistrement du nouveau joueur." << std::endl; // The code launches but no file is created.
myFile << "{"<< std::endl;
myFile << "name: " + playerPtr->getName() <<std::endl;
} else {
std::cout << "Erreur d'enregistrement du fichier." << std::endl;
}
}
I would like to be able to access the object created in createPlayer method inside the savePlayer method by passing a pointer but I just get an empty string for
playerPtr->getName()
I don't understand how the object is accessible before the call of the method and after but not inside as the address is still valid.
EDIT1
Thank you for guiding me to the obvious mistake !
Because of recuring crash of code:blocks my getName() method was deleted before I could save it and I did not think about checking it. By writing the following getName() it worked:
std::string Player::getName() const
{
return m_name;
}
Yet I do not understand why and How I got an output in createPlayer() although the method getName() was empty. Is this normal ?
EDIT 2
I'll create a new question for this strange behavior.

The code you have should work fine. My only guess is that there's something fishy about your getter function getName().
I presume you have something along these lines?
const std::string &getName() const
{
return name;
}
