Zend 框架 2 回调过滤器 [英] Zend framework 2 callback filter

问题描述

在 ZF2 中，是否可以将表单值数组传递给类似于回调验证器的回调过滤器?

In ZF2, is it possible to pass form values array to the callback filter similar to the callback validator?

//Validator callback works
'callback' => function($value, $context){
  //$context contains form values
}

//Need similar functionality for filter
'callback' => function($value, $context){
  //$context will issue a warning because its not set
}

//I know the following filter works, but I dont know how to pass the form
'callback' => function($value, $context){
  print_r($context); //Prints 'hello world'
},
'options' => array(
  'callback_params' => array(
    'context' => 'hello world' //I need this to be the form values
  )
)

推荐答案

InputFilter 没有你想要的，但是你可以使用 use 将 Form 对象传递给你的回调并获取原始表单来自输入过滤器的值

InputFilter doesn't have what you want, But you can pass the Form object to your callback using use and get the raw form values from input filter

$form = $this;

'callback' => function($value) use ($form) {
  var_dump($form->getInputFilter()->getRawValues());
}
