symfony2 学习2 表单创建 使用

第一步 使用 命令 创建 实体类

php bin/console doctrine:generate:entity

<?phpnamespace AppBundle\Entity;use Doctrine\ORM\Mapping as ORM;/** * ApiType * * @ORM\Table(name="api_type") * @ORM\Entity(repositoryClass="AppBundle\Repository\ApiTypeRepository") */class ApiType{    /**     * @var int     *     * @ORM\Column(name="id", type="integer")     * @ORM\Id     * @ORM\GeneratedValue(strategy="AUTO")     */    private $id;    /**     * @var string     *     * @ORM\Column(name="title", type="string", length=255)     */    private $title;    /**     * @var int     *     * @ORM\Column(name="status", type="integer", nullable=true)     */    private $status;    /**     * @var \DateTime     *     * @ORM\Column(name="updated_at", type="datetime")     */    private $updatedAt;    /**     * @var \DateTime     *     * @ORM\Column(name="created_at", type="datetime")     */    private $createdAt;    /**     * Get id     *     * @return int     */    public function getId()    {        return $this->id;    }    /**     * Set title     *     * @param string $title     *     * @return ApiType     */    public function setTitle($title)    {        $this->title = $title;        return $this;    }    /**     * Get title     *     * @return string     */    public function getTitle()    {        return $this->title;    }    /**     * Set status     *     * @param integer $status     *     * @return ApiType     */    public function setStatus($status)    {        $this->status = $status;        return $this;    }    /**     * Get status     *     * @return int     */    public function getStatus()    {        return $this->status;    }    /**     * Set updatedAt     *     * @param \DateTime $updatedAt     *     * @return ApiType     */    public function setUpdatedAt($updatedAt)    {        $this->updatedAt = $updatedAt;        return $this;    }    /**     * Get updatedAt     *     * @return \DateTime     */    public function getUpdatedAt()    {        return $this->updatedAt;    }    /**     * Set createdAt     *     * @param \DateTime $createdAt     *     * @return ApiType     */    public function setCreatedAt($createdAt)    {        $this->createdAt = $createdAt;        return $this;    }    /**     * Get createdAt     *     * @return \DateTime     */    public function getCreatedAt()    {        return $this->createdAt;    }}

第二部 创建对应的控制器

<?phpnamespace AppBundle\Controller;use Symfony\Bundle\FrameworkBundle\Controller\Controller;use Sensio\Bundle\FrameworkExtraBundle\Configuration\Route;use Symfony\Component\HttpFoundation\Request;use Symfony\Component\HttpFoundation\RedirectResponse;use AppBundle\Entity\ApiType;use AppBundle\Form\ApiTypeType;/** * @Route("/apitype"); */class ApiTypeController extends Controller{    /**     * @Route("/index",name="apitype_index")     */    public function indexAction(Request $request)    {        $em = $this->getDoctrine()->getManager();         $qb = $em->getRepository('AppBundle:ApiType')->createQueryBuilder('n');             $paginator = $this->get('knp_paginator');        $pagination = $paginator->paginate($qb, $request->query->getInt('page', 1),3);        return $this->render('AppBundle:ApiType:index.html.twig', array(            'pagination' => $pagination,        ));    }    /**     * @Route("/store")     */    public function storeAction(Request $request)    {        $apitype = new ApiType();        $form = $this->createForm(ApiTypeType::class, $apitype);        if ($request->getMethod()=='POST')        {            $form->handleRequest($request);            if($form->isValid()){                $em=$this->getDoctrine()->getManager();                $em->persist($apitype);                $em->flush();                return $this->redirect($this->generateUrl('apitype_index'), 301);            }        }        return $this->render('AppBundle:ApiType:store.html.twig', array(            // ...            'form' => $form->createView(),        ));    }    /**     * @Route("/delete")     */    public function deleteAction()    {        return $this->render('AppBundle:ApiType:delete.html.twig', array(            // ...        ));    }}

第三部 创建对应的form

<?phpnamespace AppBundle\Form;use Symfony\Component\Form\AbstractType;use Symfony\Component\Form\FormBuilderInterface;use Symfony\Component\OptionsResolver\OptionsResolver;use Symfony\Component\Form\Extension\Core\Type\SubmitType;use Symfony\Component\Form\Extension\Core\Type\DateTimeType;class ApiTypeType extends AbstractType{    /**     * @param FormBuilderInterface $builder     * @param array $options     */    public function buildForm(FormBuilderInterface $builder, array $options)    {        $builder            ->add('title')            ->add('status')            ->add('updated_at', DateTimeType::class)            ->add('created_at', DateTimeType::class)            ->add('save', SubmitType::class)        ;    }        /**     * @param OptionsResolver $resolver     */    public function configureOptions(OptionsResolver $resolver)    {        $resolver->setDefaults(array(            'data_class' => 'AppBundle\Entity\ApiType'        ));    }}

第四部 创建对应的view

{% extends 'admin.html.twig' %}{% block body %}<div class="row wrapper border-bottom white-bg page-heading">        <div class="col-lg-12">         <h1></h1>            <ol class="breadcrumb">                <li>                    <a href=""> 用户管理</a>                </li>                <li>                    <a href="">添加用户</a>                </li>            </ol>        </div>    </div>    <div class="wrapper wrapper-content animated fadeInRight">        <div class="row">            <div class="col-lg-12">                <div class="ibox float-e-margins">                    <div class="ibox-title">                        <div class="ibox-tools">                            <a class="collapse-link">                                <i class="fa fa-chevron-up"></i>                            </a>                        </div>                    </div>                    <div class="ibox-content">                                                                                                 {{ form_start(form) }}{{ form_widget(form) }}{{ form_end(form) }}                    </div>                </div>            </div>        </div>    </div>    {% endblock %}
