如何在 Symfony2 控制器中获取表单值 [英] How to get form values in Symfony2 controller

问题描述

我在 Symfony2 上使用带有以下控制器代码的登录表单

公共函数 loginAction(Request $request){$user = new SiteUser();$form = $this->createForm(new LoginType(), $user);if ($request->getMethod() == 'POST') {$form->bindRequest($request);$data = $form->getValues();//需要对这里的数据做一些事情}return $this->render('GDSiteBundle::header.html.twig', array('form' => $form->createView()));}

但我收到以下警告:

<块引用>

警告:array_replace_recursive() [function.array-replace-recursive]:参数 #1 不是 vendorsymfonysrcSymfonyComponentFormForm.php 行 593 中的数组500 内部服务器错误 - ErrorException

有人可以帮助我了解什么是不正确的，我该如何解决?谢谢.

更新:twig 文件是这样的:

{{ form_errors(form) }}<form action="{{ path('site_user_login') }}" method="POST" {{ form_enctype(form) }}><div class="level1">{{ form_row(form.username) }}<a href="javascript:void(0)" id="inscription">{% trans %}注册{% endtrans %}</a>
<div class="level2">{{ form_row(form.pwd_hash) }}<div class="forget_pass"><a href="#" id="frgt">{% trans %}忘记密码?{% endtrans %}</a></div>

<input type="submit" class="submit" name="login" value/><div class="clr"></div></表单>

这里是表单类型中的函数

public function buildForm(FormBuilder $builder, array $options){$builder->add('username', 'text', array('label' => 'Username : '));$builder->add('pwd_hash','password', array('label' => 'Password : '));}

路线如下:

site_user_login:模式:/{_locale}/login默认值:{_controller: GDSiteBundle:SiteUser:login}

解决方案

简单:

$data = $form->getData();

I am using a login form on Symfony2 with the following controller code

public function loginAction(Request $request)
{
    $user = new SiteUser();
    $form = $this->createForm(new LoginType(), $user);


    if ($request->getMethod() == 'POST') {
        $form->bindRequest($request);
        $data = $form->getValues();
        // Need to do something with the data here
    }

    return $this->render('GDSiteBundle::header.html.twig', array('form' => $form->createView()));
}

But I am getting the following warning:

Warning: array_replace_recursive() [function.array-replace-recursive]: Argument #1 is not an array in vendorsymfonysrcSymfonyComponentFormForm.php line 593 500 Internal Server Error - ErrorException

Can someone help me understand whats incorrect, and how I can fix it? Thanks.

Update: The twig file is something like this:

<div class="form">
    {{ form_errors(form) }}
    <form action="{{ path('site_user_login') }}" method="POST" {{ form_enctype(form) }}>
        <div class="level1">
            {{ form_row(form.username) }}
            <a href="javascript:void(0)" id="inscription">{% trans %}Registration{% endtrans %}</a>
        </div>
        <div class="level2">
            {{ form_row(form.pwd_hash) }}
            <div class="forget_pass"><a href="#" id="frgt">{% trans %}Forgot Password ?{% endtrans %}</a></div>
        </div>
        <input type="submit" class="submit" name="login" value/>
        <div class="clr"></div>
    </form>
</div>

Here is the function in the Form's Type

public function buildForm(FormBuilder $builder, array $options)
{
    $builder->add('username', 'text', array('label' => 'Username : '));
    $builder->add('pwd_hash','password', array('label' => 'Password : '));
}

Here is the route:

site_user_login:
    pattern: /{_locale}/login
    defaults: {_controller: GDSiteBundle:SiteUser:login}

解决方案

Simply :

$data = $form->getData();
