Question

我的表格形式为here。

但它总是$ form-＆gt; isValid（）总是返回false。

$searchTime = new SearchTime();//SearchTime is my entity name

    $form = $this->createFormBuilder($searchTime)
            ->add('fromDate','datetime')
            ->add('toDate','datetime')             
            ->getForm(); 

    $request = $this->get('request');

    if ($request->getMethod() == 'POST') {
        $form->bindRequest($request);

         var_dump($form->isValid());
        if ($form->isValid()) {

我认为$ request-＆gt; getMethod（）正确地返回'POST'，但是 $ form-＆gt; bindRequest（$ request）以某种方式无效。

有没有人暗示过这个？

我的$ request请求在这里

我正在解决这个问题。

$form = $this->createFormBuilder($searchTime, array(
                'csrf_protection' => false,     // disables CSRF for the form
            ))               
        ->add('fromDate','datetime')
        ->add('toDate','datetime')             
        ->getForm(); 


$request = $this->get('request');
var_dump($request);// it contains PostData correctly,I can see there is 'fromDate' and value. 

$form->bindRequest($request);//I am trying to bind postdata with form...
$form->get('fromDate')->getData(); // it returns null......

额外的

var_dump（$ request-＆gt; request）似乎返回表单数据....

object(Symfony\Component\HttpFoundation\ParameterBag)#7 (1) {
      ["parameters":protected]=>
      array(1) {
        ["form"]=>
        array(2) {
          ["fromDate"]=>
          array(2) {
            ["date"]=>
            array(3) {
              ["year"]=>
              string(2) "13"
              ["month"]=>
              string(1) "1"

    }

问题已解决

制作表格时

    $years = array(date("y", strtotime("now")),date("y", strtotime("+1 year")));
    $form = $this->createFormBuilder($searchTime,array(
'csrf_protection' => false,     // disables CSRF for the form
        ))
        ->add('fromDate',null,array(
            'label' => 'start time',
            'years' => $years
            'minutes' => array('0','30')
            ))

我使用$ years = array（date（“y”，strtotime（“now”）），date（“y”，strtotime（“+ 1 year”）））; 限制年度选择至2013,2014

但它返回数组（13,14）而不是（2013,2014）

所以form-＆gt; bindrequest不起作用

Answer 1

您可能默认启用了CSRF保护，导致您的表单无效，请尝试

$form = $this->createFormBuilder($searchTime, array(
    'csrf_protection' => false,     // disables CSRF for the form
))->add(...)

config.yml中的常规配置设置可以在 framework.csrf_protection

下找到

framework:
    # ...
    csrf_protection:
        enabled:      false

否则调试你得到的错误：

 $form->getErrors()

确保提交正确的值......

["year"]=>string(2) "13"     // year 13 ? .... 2013?

应该是

["year"]=>string(2) "2013"

关于bindRequest（），$ form-＆gt; isValid（）的麻烦
