mapFormsToData()
Maps the model data of a list of children forms into the view data of their parent.
public
mapFormsToData(array<string|int, FormInterface>|Traversable $forms, mixed &$viewData) : mixed
This is the internal cascade call of FormInterface::submit for compound forms, since they cannot be bound to any input nor the request as scalar, but their children may:
$compoundForm->submit($arrayOfChildrenViewData)
// inside:
$childForm->submit($childViewData);
// for each entry, do the same and/or reverse transform
$this->dataMapper->mapFormsToData($compoundForm, $compoundInitialViewData)
// then reverse transform
When a simple form is submitted the following is happening:
$simpleForm->submit($submittedViewData)
// inside:
$this->viewData = $submittedViewData
// then reverse transform
The model data can be an array or an object, so this second argument is always passed by reference.
Parameters
- $forms : array<string|int, FormInterface>|Traversable
-
- $viewData : mixed
-
The compound form's view data that get mapped its children model data
