Question

I want to create a form using some fields from multiple entities. I have all the distinct entites needed already created and i am not using form classes. I need to know how to do to render a form and handle its data so i can save them to the correct tables in my database.

Here is a part of my controller in charge of doing that

public function createPublicSpaceAction() {
    //My entities
    $Room = new Room();
    $GuestList = new GuestList();
    $Guest = new Guest();

    //I need to know what to do from here

    return $this -> render('AcmeUserBundle:Default:Forms/createPublicSpace.html.twig', array());
}

I kept trying to find a solution and i came up with the idea that one form needs one entity. So maybe the solution would be to merge those entities in one so i can build the form easily. I would then have to persist data to corresponding tables. But i can’t think of how to merge entities.

Answer 1

I figured out a temporary solution. For those who want to know, I manually created an entity that looks like a merge of all the entity I need. This new entity has no link with Doctrine therefore it cannot create a table. Its goal is simply to allow me to build up a form and be able to manipulate data through that form. I then assign all data submitted to corresponding entities fields and persist them to the database.

Once again i know this is not the best solution. But for some reasons I won’t tell, it is for me at this moment. I hope this can help some that are in the same situation than me and do not hesitate to post links that could help or better ways to do that.
