/**
|
|
* Class AddToCampaignHandler - handle the AddToCampaign action.
|
|
*
|
|
* This is a class designed to be delegated to by a Form action handler method in the EditForm of a LeftAndMain
|
|
* child class.
|
|
*
|
|
* Add To Campaign can be seen as an item action like "publish" or "rollback", but unlike those actions
|
|
* it needs one additional piece of information to execute, the ChangeSet ID.
|
|
*
|
|
* So this handler does one of two things to respond to the action request, depending on whether the ChangeSet ID
|
|
* was included in the submitted data
|
|
* - If it was, perform the Add To Campaign action (as per any other action)
|
|
* - If it wasn't, return a form to get the ChangeSet ID and then repeat this action submission
|
|
*
|
|
* To use, you'd add an action to your LeftAndMain subclass, like this:
|
|
*
|
|
* function addtocampaign($data, $form) {
|
|
* $handler = AddToCampaignHandler::create($form, $data);
|
|
* return $handler->handle();
|
|
* }
|
|
*
|
|
* and add an AddToCampaignHandler_FormAction to the EditForm, possibly through getCMSActions
|
