12. Routing 12
13. /my/url?q=a controller/action ? 13
14. ➡ Routing starts in app/config/routing.yml (or xml, or php) 14
15. # app/config/routing.yml blog_index: pattern: /blog defaults: { _controller: AcmeBlogBundle:Blog:index } 15
16. # app/config/routing.yml blog_index: pattern: /blog defaults: { _controller: AcmeBlogBundle:Blog:index } blog_show: pattern: /blog/{slug} defaults: { _controller: AcmeBlogBundle:Blog:show } 16
17. TWIG 17
18. <?php namespace Noxlogic\GuestbookBundle\Controller; use Symfony\Bundle\FrameworkBundle\Controller\Controller; class DefaultController extends Controller { public function indexAction($name) { return $this->render('NoxlogicGuestbookBundle:Default:index.html.twig', array('name' => $name)); } } Template name Format Engine Parameters This template can be found at: /src/Noxlogic/GuestbookBundle/views/Default/index.html.twig 18
19. ➡ Output something {{ }} ➡ Do something {% %} ➡ Comments {# #} 19
20. ➡ Like most things in symfony2, don’t hardcode URLs. ➡ Use “path” and/or “url” 20
21. {% foreach user in users %} <a href=”{{ path(‘user_details’, { ‘id’: user.id }) }}”> {{ user.name | capitalize }}</a> {% endfor %} <a href=”{{ url(‘homepage’); }}>Go back to the homepage</a> Use path() for relative URLs Use url() for absolute URLs 21
22. FORMS 22
23. <?php namespace Noxlogic\GuestbookBundle\Controller; use Symfony\Bundle\FrameworkBundle\Controller\Controller; use Noxlogic\GuestbookBundle\Form\CommentType; class CommentController extends Controller { public function indexAction() { $form = $this->createFormBuilder() ->add('name', 'text') ->add('email', 'email') ->add('comment', 'textarea') ->getForm(); return $this->render('NoxlogicGuestbookBundle:Comment:index.html.twig', array('form' => $form->createView())); } } 23
24. <?php namespace Noxlogic\GuestbookBundle\Form; use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; class CommentType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add('name'); $builder->add('email', 'email'); $builder->add('comment', 'textarea'); } public function getName() { return 'comment'; } } src/Noxlogic/GuestbookBundle/Form/ CommentType.php 24 Move the form to its own class
25. <?php namespace Noxlogic\GuestbookBundle\Controller; use Symfony\Bundle\FrameworkBundle\Controller\Controller; use Noxlogic\GuestbookBundle\Form\CommentType; class CommentController extends Controller { public function indexAction() { $form = $this->createForm(new CommentType()); return $this->render('NoxlogicGuestbookBundle:Comment:index.html.twig', array('form' => $form->createView())); } } src/Noxlogic/GuestbookBundle/Controller/CommentController.php 25 Keeps the controllers small and clean.
26. 26 http://webmozarts.com/2012/03/06/symfony2-form-architecture/ default available in the form extension added by extensions
27. Form validation 27
28. ➡ We can add validators to our form(entries). ➡ isValid() will check form values, and create errors which can be displayed with the form_errors() twig function. 28
29. <?php namespace Noxlogic\GuestbookBundle\Form; use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; use Symfony\Component\Validator\Constraints; class CommentType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add('name', 'text', array( 'constraints' => new Constraints\NotBlank(), )); $builder->add('email', 'email'); $builder->add('comment', 'textarea', array( 'constraints' => array( new Constraints\NotBlank(), new Constraints\Length(array('min' => 10, 'max' => 50)), ) )); } public function getName() { return 'comment'; } } 29
30. ➡ NotBlank ➡ Blank ➡ NotNull ➡ Null ➡ True ➡ False ➡ Type ➡ Email ➡ MinLength ➡ MaxLength ➡ Length ➡ Url ➡ Regex ➡ Ip ➡ Max ➡ Min ➡ Range ➡ Date ➡ DateTime ➡ Time ➡ Choice ➡ Collection ➡ Count ➡ UniqueEntity ➡ Language ➡ Locale ➡ Country ➡ File ➡ Image ➡ Callback ➡ All ➡ UserPasswor d ➡ Valid 30
31. <?php namespace Noxlogic\GuestbookBundle\Form; use Symfony\Component\Form\AbstractType; use Symfony\Component\Form\FormBuilderInterface; use Symfony\Component\Validator\Constraints; class CommentType extends AbstractType { public function buildForm(FormBuilderInterface $builder, array $options) { $builder->add('name', 'text', array( 'constraints' => new Constraints\NotBlank(), )); $builder->add('email', 'email'); $builder->add(‘country’, ‘country’); $builder->add('comment', 'textarea', array( 'constraints' => array( new Constraints\NotBlank(), new Constraints\Length(array('min' => 10, 'max' => 50)), ) )); } public function getName() { return 'comment'; } } 31
32. ➡ Validations etc can be added to configuration to simplify things. ➡ Normally, validation is done on “entities”. 32
33. 33 ➡ As with (almost) anything, you can write your custom validators as well. ➡ Check for valid customer-id, ISBN, VAT numbers etc..
34. Using entities 34
35. ➡ Form data is usually coupled to models/ entities ➡ Doctrine2, but standalone models are possible too. 35
36. <?php namespace NoxLogic\GuestbookBundle\Entity; class Comment { protected $name; protected $email; protected $comment; // getters and setters getName(), setName() etc.. } 36
37. <?php namespace Noxlogic\GuestbookBundle\Controller; use Symfony\Bundle\FrameworkBundle\Controller\Controller; use Noxlogic\GuestbookBundle\Form\CommentType; use Noxlogic\GuestbookBundle\Entity\Comment; class CommentController extends Controller { public function indexAction() { $comment = new Comment(); $form = $this->createForm(new CommentType(), $comment); $request = $this->getRequest(); if ($request->getMethod() == "POST") { $form->handleRequest($request); // $comment is now filled with our form values if ($form->isValid()) { $this->get("session")->setFlash("notice", "Thank you for posting your comment!"); $url = $this->generateUrl("noxlogic_guestbook_homepage", array("name" => $comment->getName())); return $this->redirect($url); } } return $this->render('NoxlogicGuestbookBundle:Comment:index.html.twig', array( 'form' => $form->createView()) ); } } 37
38. Doctrine2 38
39. class User { protected $id; protected $firstname; protected $lastname; protected $email; protected $birthdate; } 39
40. use Doctrine\ORM\Mapping AS ORM; /** @ORM\Entity */ class User { /** * @ORM\Id * @ORM\GeneratedValue * @ORM\Column(type=”integer”) */ protected $id; /** @ORM\Column(type=”string”, length=25); protected $firstname; /** @ORM\Column(type=”string”, length=25); protected $lastname; /** @ORM\Column(type=”string”, length=50); protected $email; /** @ORM\Column(type=”date”); protected $birthdate; } 40
41. ➡ The entitymanager takes care of loading and saving your entities (through repositories). 41
42. public function indexAction() { $user = new User(); $user->setFirstName(“John”); $user->setLastName(“Doe”); $user->setBirthdate(new \DateTime(“1 august 1980”)); $em = $this->getDoctrine()->getManager(); $em->persist($user); $em->flush(); } 42
43. public function indexAction() { $user = $this->getDoctrine() ->getRepository(“NoxlogicBundle:User”) ->find(1); if (!$user) { throw new \HttpNotFoundException(); } $this->render(“myview.html”, array(“user” => $user)); } 43
44. $usersNamedJohn = $this->getDoctrine() ->getRepository(“NoxlogicBundle:User”) ->findAllByFirstName(“John”); $usersNamedDoe = $this->getDoctrine() ->getRepository(“NoxlogicBundle:User”) ->findAllByLastName(“Doe”); $em = $this->getDoctrine()->getManager(); foreach ($usersNamedDoe as $doe) { $em->remove($doe); } $em->flush(); 44
45. ➡ Repositories provides ways to find / query for your entities. ➡ Standard repository: ➡ fetchAll, fetchOne, fetchAllBy*, fetchOneBy* 45
