通过AJAX将表单数据作为参数传递给Symfony2控制器功能

Question

I think this is one of the more complex tricks to get right and therefore I have decided to elicit the help of the very knowledgeable people on StackOverflow. My scenario is as follows: I have two entities, a user and an account. A user is always linked to an account upon registration (and depending on the type of user, might be linked to more than one account. Upon registration the function saveUser() is called (via ajax from frontend) and the submitted form data is retrieved from the Request Object. This data is then passed to the function saveAccount($data) (which is called in the saveUser() function) in the form of a parameter and the account is created (sometimes called more than once with different data sets to create various accounts), which is linked to the user.

Now I want to create an account from my admin panel without creating a user, so I want to call saveAccount($data) directly via ajax (from frontend) and pass the form data to it as a PARAMETER (instead of retrieving it in the function via the Request Object), so that I can use the same saveAccount($data) function and that I do not have to create a saveAccount() which works the the Request variable. Does this make sense? Is this possible? If so, how would I go about doing this?

I did not post any code, as I did not see the need for it, this is more a conceptional problem, but if you require the code that I have thus far or if anything is unclear I will be happy to elaborate.

Answer 1

There should not be any saveAccount method, you just rely on relationships between entities, ie on a setAccount method, or to a addAccount one in case you need to add an entity to a Collection .

Then Doctrine will take care of saving and persisting everything.

For saving data, I would always rely on a RESTful interface [which you can create easily via FOSRestBundle ], and send everything via ajax no matter what; you'll end up with a smoother interface and more maintainable code.

Answer 2

For instances where a controller function can be called either via AJAX with form data or internally by a another controller function the following solution works:

public function saveAccount($data = null)
{
    if (empty($data)) $data = $this->getRequest()->request->all();
    ...
}

Then you can pass an array to the controller function in the same format as your form data array and it will use that data if passed to the function, otherwise it will retrieve the REQUEST (form) data.
