zf2 验证:如何验证依赖字段? [英] zf2 validation: How can I validate dependent fields?

问题描述

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".

How can I set a input filter which is dependent from another input field. I want to verify that the 'apDepTime' field is more than 'apArrTime'.

我如何在 zf2 中处理这个问题?

How can i handle this in zf2?

我还想说明我正在使用日期验证器".

I also want to note that I am using 'Date validator'.

请任何人帮助我.

推荐答案

您可以为此使用 Zend\Validator\Callback 验证器

You can use the Zend\Validator\Callback validator for this

传递给回调的第一个参数是应用验证器的输入值.

The first parameter passed to your callback is the value of the input to which the validator is applied.

第二个参数是由输入名称键控的其他表单值的数组，表示要比较值的上下文.

The second parameter is an array of your other form values keyed by input names and represents the context in which you want to compare values.

举个简单的例子...

    $apArrInputFilter->add($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，但这应该会让您开始.

Obviously you'll need to write code to your needs for the actual date comparison, but that should get you started.
