在 zendframework2 中验证日期 [英] validating date in zendframework2

问题描述

我想从 zf2 验证日期字段形式.我设置了格式"选项以获得我需要的格式.但是每次我验证它时都会出错.验证器看起来像这样:

Hiho, I would like to validate a date field from an zf2 form. I set the 'format' option to get the format I need. But at every time I validate it i get an error. The validator looks like this:

            $inputFilter->add($factory->createInput(array(
            'name' => 'user_data_birth',
            'required' => false,
            'validators' => array(
                array(
                'name' => 'Date',
                'options' => array(
                    'format' => 'd.m.Y',
                    'locale' => 'de',
                    'messages' => array(
                        \Zend\Validator\Date::INVALID => 'Das scheint kein gültiges Datum zu sein.',
                        \Zend\Validator\Date::INVALID_DATE => 'Das scheint kein gültiges Datum zu sein. (Invalid Date)',
                        \Zend\Validator\Date::FALSEFORMAT => 'Das Datum ist nicht im richtigen Format.',
                        ),
                    ),
                ),
                array(
                    'name' => 'NotEmpty',
                    'options' => array(
                    'messages' => array(
                        \Zend\Validator\NotEmpty::IS_EMPTY => 'Bitte geben Sie das Datum an'
                        ),
                    ),
                )
            ),
        )));

但每次我都会收到日期格式错误的错误信息.

But I get every time an error that the date is in the wrong format.

推荐答案

可以解决开始日期应该小于结束日期验证的问题，使用回调函数如下:

You can solve the problem of, start date should be less than end date validation, using the Callback function as below:

          $inputFilter->add($factory->createInput(array(
                'name' => 'end_date',
                'required' => true,                 
                'filters' => array(
                        array('name' => 'StripTags'),
                        array('name' => 'StringTrim'),
                ),
                'validators' => array(
                    array(
                        'name' => 'Callback',
                        'options' => array(
                            'messages' => array(
                                    \Zend\Validator\Callback::INVALID_VALUE => 'The end date should be greater than start date',
                            ),
                            'callback' => function($value, $context = array()) {                                    
                                $startDate = \DateTime::createFromFormat('d-m-Y', $context['start_date']);
                                $endDate = \DateTime::createFromFormat('d-m-Y', $value);
                                return $endDate >= $startDate;
                            },
                        ),
                    ),                          
                ),
        )));

使用上面的代码，我已经解决了我的问题.我希望这会有所帮助.
