Change the input name to: "category-new[]" to make it an array.

in the controller:

$categories = $this->getRequest()->get('category-new');
foreach($categories as $category) {
    $categoryName = new Category();
    $categoryName->setName($category);


    $em = $this->getDoctrine()->getManager();
    $em->persist($categoryName);
}
$em->flush();
