function editableviews_handler_field_field_edit::edit_form in Editable Views 7

Add the form element for this handler's field to the form.

We break this out into the handler to allow other handlers that work with non-FieldAPI fields (eg node title) to also provide a form element.

Parameters

$entity_type: The entity type.

$entity: The entity.

&$element: The partial form, at $form[ENTITY_ID]. This is passed by reference and should be altered in place.

&$form_state: The form state.

Class

editableviews_handler_field_field_edit

Field handler for toggling between rendered value and edit form element.

Code

function edit_form($entity_type, $entity, &$element, &$form_state) {
  list($entity_id, $vid, $bundle) = entity_extract_ids($entity_type, $entity);

  // store class names in the form rather than handler objects, which would
  // considerably save on form cache size!

  // Because a View result can show entities of different bundles, it is
  // essential that we check the field actually exists on the current entity.
  // ctools_field_invoke_field() does actually check for this too, but that
  // only works when it's passed a field name rather than a whole instance.

    // We also need to set the module for the widget, in case this differs

  // On new entities, force this to not be required, to allow the user to not
  // create the new entity.
  // Obviously, problems arise when there are multiple editable fields on
  // this entity, since the title *is* required if actually creating an
  // entity!
  // TODO: consider this thorny problem.
