validation - zf2验证: How can I validate dependent fields?

Question

如何设置依赖于另一个输入字段的输入过滤器。我想验证“apDepTime”字段是否大于“apArrTime”。

我该如何在 zf2 中处理这个问题？

我还想指出，我正在使用“日期验证器”。

请任何人帮助我。

Answer 1

您可以为此使用 Zend\Validator\Callback 验证器

传递给回调的第一个参数是应用验证器的输入值。

第二个参数是由输入名称键入的其他表单值组成的数组，表示您要在其中比较值的上下文。

作为一个简单的例子......

    $apArrInputFilter->add($factory->createInput(array(
        'name' => 'apArrTime',
        'required' => true,
        'validators' => array(
                array(
                    'name' => 'Callback',
                    'options' => array(
                        'messages' => array(
                            \Zend\Validator\Callback::INVALID_VALUE => 'The departure time is less than the arrival time',
                        ),
                        'callback' => function($value, $context=array()) {
                            // value of this input
                            $apArrTime = $value;
                            // value of input to check against from context
                            $apDepTime = $context['apDepTime'];
                            // compare times, eg..
                            $isValid = $apDepTime > $apArrTime;
                            return $isValid;
                        },
                    ),
                ),
        ),
    )));

显然，您需要根据实际日期比较的需要编写代码，但这应该可以帮助您开始。
