Symfony2框架实战教程

window下安装

在环境变量里面配置php,然后用php在cmd里面执行

php -r "file_put_contents('symfony', file_get_contents('https://symfony.com/installer'));"

上句执行好了，在执行这句，是创建一个新的symfony工程：php symfony new my_project_name

form表单的写法

2点级版本的写法

$form=$this->createFormBuilder($task)

->add('task','text')

->add('dueDate','date')

->add('save','submit',array('label'=>'Create Task'))

->getForm();

3.0以上的写法

$form = $this->createFormBuilder($task)
    ->add('task', TextType::class)
    ->add('dueDate', DateType::class)
    ->add('save', SubmitType::class, array('label' => 'Create Task'))
    ->getForm();

需要引入

use SymfonyComponentFormExtensionCoreTypeTextType;
use SymfonyComponentFormExtensionCoreTypeDateType;
use SymfonyComponentFormExtensionCoreTypeSubmitType;

return $this->redirectToRoute('login_index');重定向

注册用的是orm映射

//这个方法是创建出一个注册的form表单

public function indexAction(Request $request)
{
$user = new User();

$form = $this->createFormBuilder($user)
        ->setAction($this->generateUrl('register_register'))
        ->setMethod('post')
        ->add('username', TextType::class)
        ->add('password', PasswordType::class)
        ->add('email', TextType::class)
        ->add('phone', TextType::class)
        ->add('gender', TextType::class)
        ->add('save', SubmitType::class, array('label' => 'Register'))
        ->getForm();

return $this->render('register/index.html.twig', array(
'form' => $form->createView()
    ));
}

//V层twig展现出来

{{ form_start(form) }}
{{ form_widget(form) }}
{{ form_end(form) }}

//这个方法是得到form表单是数据，得到的form是一个对象，要转化成数组，然后插入到数据库

public function registerAction(Request $request)
{

$user = new User();

$user->setLoginIp($request->getClientIP());//得到本机的IP地址

$user->setLoginTimes(new DateTime('now'));//得到当前时间

$form = $this->createFormBuilder($user)
    ->add('username', TextType::class)
    ->add('password', PasswordType::class)
    ->add('email', TextType::class)
    ->add('phone', TextType::class)
    ->add('gender', TextType::class)
    ->getForm();

$form->handleRequest($request);

$data = $form->getData();
json_encode($data);

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

return $this->redirectToRoute('login_index');

在控制器里跳同控制器的方法还带传参
