Persist multiple entities in symfony2 - symfony

Question

I cannot persist multiple entities inside the controller. I can only save the last one.
My code:
$product = new Product();
$names = ['yellow', 'blue', 'red']; // save these to the table
foreach ($name as $name) {
$product->setName($name);
$em->persist($product);
// $em->flush(); // doesn't work either
}
$em->flush();
I am using Symfony 2.7

Answer 1

You have to create a new Product inside your loop.
Right now it's only taking 1 product, and it's constantly updating that one.
$names = ['yellow', 'blue', 'red']; // save these to the table
foreach ($names as $name) {
$product = new Product();
$product->setName($name);
$em->persist($product);
}
$em->flush();

Answer 2

I created this solution which looks nice:
array_walk($arrayOfEntities, function ($entity) {
$entityManager->persist($entity);
});

Answer 3

Use clone operator (php 5+)
$product = new Product();
$names = ['yellow', 'blue', 'red'];
foreach ($names as $name) {
$tmpProductObj = clone $product;
$em->persist($tmpProductObj);
}
$em->flush();
More information about cloning an object can be found here

Answer 4

You are only creating one Object Product.
Obviously, only one object will be persisted to the database then.
Also at the top your variable is called $Product(capital P) while in the loop it is called $product.
Try this instead:
$NameList = array("yellow","blue","red"); // save these to the table
foreach($NameList as $name){
$product = new Product();
$product->setName($name);
$em->persist($Product);
//$em->flush(); // doesnot work either
}
$em->flush();

If I want add multiple objects after set its value I use clone in loop:
$application = new Application();
$application->setSomething($someting);
for ($i = 1; $i <= $request->get('number_of_applications'); $i++){
$applicationObj = clone $application;
$em->persist($applicationObj);
}
$em->flush();
