Transactions
The ODM provides transaction support if the underlying persistence layer supports them.
transactional()
The Doctrine\ODM\PHPCR\DocumentManager#transactional() method provides support for, executing
functions in a transactional-safe manner if the underlying PHPCR transport supports it. Any PHP
callable type is supported.
Example:
use Doctrine\ODM\PHPCR\DocumentManager;
$documentManager = new DocumentManager($session);
$documentManager->transactional(function(DocumentManager $documentManager) {
$document = new Article('Cool story!');
$comment = $article->comment('Amazing indeed!');
$documentManager->persist($document);
$documentManager->persist($comment);
});
As you can see, there is also no need to call Doctrine\ODM\PHPCR\DocumentManager#flush(),
since Doctrine\ODM\PHPCR\DocumentManager#transactional() will do it implicitly.
If an Exception is thrown during Doctrine\ODM\PHPCR\DocumentManager#transactional()
execution, then the Doctrine\ODM\PHPCR\DocumentManager will be closed and the current transaction
rolled back.
