Pass parameters to Pimple->container->factory

Question

So I basically want to do this:

$this->container['Menu_builder'] = $this->container->factory(function ($c) {
    return new Menu_builder($parameter_1, $parameter_2);
});

Where $parameter_1 and $parameter_2 are passed in from the call, like this:

$menu_builder = $this->container['Menu_builder']('account', 'reset_password');

I know the above syntax is incorrect, but I want to pass these strings into the call to $this->container->factory.

Is this possible?

For example, if I wanted to instantiate the Menu_builder from various controller functions with different parameters for each controller function.

So your problem is, that `$parameter_1`/`_2` are out of scope in your anonymous function ? — Rizier123, May 16 '15 at 22:47
Yeah exactly, so how do you pass them in? Hopefully I havent found the one use case of Pimple that you cant do! — Donal.Lynch.Msc, May 16 '15 at 22:48
Well you already have your answer in your comment ^ :) `use`, e.g. `function ($c)use($parameter_1, $parameter_2){` — Rizier123, May 16 '15 at 22:51
Any chance you could give me an example, as I cant seem to pass the vars into the closure for some reason? — Donal.Lynch.Msc, May 16 '15 at 23:01
This might be of help: https://github.com/silexphp/Pimple/issues/13#issuecomment-3409414 — mpen, May 19 '15 at 01:14
@Rizier123 Yeah that worked like a charm! If you make an answer out of your comment Ill accept it :-D — Donal.Lynch.Msc, May 19 '15 at 21:53

FWIW, you can also include an anonymous function within your container.

$this->container['Menu_builder'] = function() {
    // do stuff here

    return function($parameter_1, $parameter_2) {
        return new Menu_builder($parameter_1, $parameter_2);
    };
};

Use this way:

$localfunc = $this->container['Menu_builder'];
$result = $localfunc($parameter_1, $parameter_2);

Notice that in this case I'm not using a factory. That's because you can execute the anonymous function with different values each time.

You just can use use() to pass your variables to the anonymous functions, e.g.

//your parameters needs to be defined here:
$parameter_1 = "XY";
$parameter_2 = 42;

$this->container['Menu_builder'] = $this->container->factory(function ($c)use($parameter_1, $parameter_2) {
                                                                        //^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ See here
    return new Menu_builder($parameter_1, $parameter_2);
});

And when defined in a service provider? I think parameters are meant to be passed by defining a container value - ie $container['param1'] = 'some value'. The anonymous function can then access via $container['param1'] – Brad Kent Sep 20 '15 at 02:21
