grab value from request, or from form

[Steve Rayner-2]

In ZF2 i'm trying to hydrate a doctine object from a zend form. The
object's properties are populated ok apart from properties that are other
objects (ie relationships).
Unless there is a better way, i can just create the other objects on the
fly and set the properties of the inital object that i'm trying to hydrate.
(i seem to remember there is a better way of doing this in doctrine)

Now i'm stuck, I can't find in the documentation how i can access a single
parameter from the request object, or from the form object.
Can anyone show me how to do this?

From the form object, what you will do after validation is one of the
following:

    // This is new as of RC1
    $value = $form->get('element-name')->getValue()

    // This will work in beta4 -> current
    $filter = $form->getInputFilter();
    $value  = $filter->getValue('element-name');

To grab from the request, you can use the params() plugin, and pull from
the appropriate source:

    $value = $this->params()->fromPost('key-name');
    $value = $this->params()->fromQuery('key-name');
    $value = $this->params()->fromRoute('key-name');
