Forms: Provide a link to edit an item that was just created

[dtdesign]

Forms are generally designed to reset themselves after submitting and providing a clean form afterwards. There is usually a generic success message at the top, which we can extend to provide a link to edit the just created item.

We should check if it is possible to generate these links automatically without requiring any manual edits.

This does not appear to be possible generically. I've checked a few forms and none even expose the ID of the created entity, even less a link to it. With form builder based forms it should be possible, though.

Most forms do expose the $this->objectAction which does contain the object in $this->objectAction->getReturnValues()['returnValues'];. It should be possible to check if the return value is a wcf\data\DatabaseObject and generate a link using getObjectID()?

In fact that property is part of AbstractForm.

Unfortunately the language item that is typically used (wcf.global.success.add) is within the wcf.global category and thus does not support template scripting.

[dtdesign]

Introduce a new template formSuccess that replaces this bit:

{if $success|isset}
	<p class="success" role="status">{lang}wcf.global.success.{$action}{/lang}</p>
{/if}

The template could then offer a proper UI for the user, additionally the form class can assign the specific object (similar to the WCF::getTPL()->assign('success', true) to avoid testing arbitrary return values of the dbo action.
