Doctrine multiple flush commit once - mysql

Question

I do a lot of search without success.
I would like to understand the flush() process in this situation.
//Edit updateOptions
public function updateOptions($values){
setOption('country',$values['country']);
setOption('city',$values['city']);
setOption('adress',$values['adress']);
setOption('CP',$values['CP']);
setOption('country_code',$values['country_code']);
}
function setOption($name, $value){
$em = $this->getEntityManager('option.manager');
$option = $this->getOption($name); //Entity Options
$option->setValue($value);
$em->persist($option);
$em->flush();
}
When I look the mysql.log or the profiler, i found this:
START TRANSACTION
UPDATE options SET value = 'France' WHERE name = 'country';
COMMIT
START TRANSACTION
SAVEPOINT DOCTRINE2_SAVEPOINT_2
UPDATE options SET value = 'Paris' WHERE name = 'city';
RELEASE SAVEPOINT DOCTRINE2_SAVEPOINT_2
SAVEPOINT DOCTRINE2_SAVEPOINT_2
UPDATE options SET value = 'Rue de Rivoli' WHERE name = 'adress';
RELEASE SAVEPOINT DOCTRINE2_SAVEPOINT_2
SAVEPOINT DOCTRINE2_SAVEPOINT_2
UPDATE options SET value = '75001' WHERE name = 'CP';
RELEASE SAVEPOINT DOCTRINE2_SAVEPOINT_2
SAVEPOINT DOCTRINE2_SAVEPOINT_2
UPDATE options SET value = '33' WHERE name = 'country_code';
RELEASE SAVEPOINT DOCTRINE2_SAVEPOINT_2
ROLLBACK
Only the first one is updated/committed, I get it, but i don't see why the next are rolled back?
This situation also occur if I use setOption() inside a loop for example.
A help would be great.
Thanks in advance.

Don not call persist() and flush() each time. I assume that could be the reason. Since you don not explicit tell EM to start a transaction it probably tries to guess it by combination of persist() and flush()
try following:
extend your updateOptions method
public function updateOptions ()
{
$em = $this->getEntityManager( 'option.manager' );
$em->beginTransaction();
setOption( 'country', 'France' );
setOption( 'city', 'Paris' );
setOption( 'adress', 'Rue de Rivoli' );
setOption( 'CP', '75001 ' );
setOption( 'country_code', '33' );
$em->flush(); //just notif EM there're records to UPDATE
//$success = false;
try
{
$em->commit();
//$success = true;
}
catch ( \Exception $ex )
{
$em->rollback();
// my fav is followinn: in DEV re-throw exception so you can inspect all in symfony-debug-bar
// in prod just additional emergency log (monolog + swiftmailer) so you get an email
if( $this->get( 'kernel' )->getEnvironment() !== 'prod' )
{
throw $ex;
}
$this->get( 'logger' )->addEmergency( 'Oh nooo! Not again :/' );
}
//return $success;
}
function setOption($name, $value){
$option = $this->getOption($name); //Entity Options
$option->setValue($value);
}
