zendframework 2 inputfilter 自定义默认错误信息 [英] zendframework 2 inputfilter customize default error message

问题描述

我正在尝试自定义默认错误消息Value is required and can't be empty"在 zf2

I am trying to customize the default error message "Value is required and can't be empty" in zf2

我正在使用以下代码在 inputfilter 的验证器中添加自定义默认错误消息

I am using following code to add customise default error message in validators of inputfilter

$inputFilter->add($factory->createInput(array(
                'name' => 'username',
                'required' => true,
                'filters' => array(
                    array('name' => 'StripTags'),
                    array('name' => 'StringTrim'),
                ),
                'validators' => array(
                    array(
                        'name' => 'StringLength',
                        'options' => array(
                            'encoding' => 'UTF-8',
                            'min' => 4,
                            'max' => 20,
                            'messages' => array(
                                'isEmpty' => 'Please enter User Name between 4 to 20 character!' 
                            ),                            
                        ),
                    ),
                ),
            )));

但我收到以下错误.

Zend\Validator\Exception\InvalidArgumentException

File:
    /home/website/vendor/zendframework/zendframework/library/Zend/Validator/AbstractValidator.php:220

Message:
    No message template exists for key 'isEmpty'

我做错了什么?

$inputFilter->add($factory->createInput(array(

                'required' => true,
                'filters' => array(
                    array('name' => 'StripTags'),
                    array('name' => 'StringTrim'),
                ),
                'validators' => array(
                    array(
                      'name' =>'NotEmpty', 
                        'options' => array(
                            'messages' => array(
                                \Zend\Validator\NotEmpty::IS_EMPTY => 'Please enter User Name!' 
                            ),
                        ),
                    ),
                    array(
                        'name' => 'StringLength',
                        'options' => array(
                            'encoding' => 'UTF-8',
                            'min' => 4,
                            'max' => 20,
                            'messages' => array(
                                'stringLengthTooShort' => 'Please enter User Name between 4 to 20 character!', 
                                'stringLengthTooLong' => 'Please enter User Name between 4 to 20 character!' 
                            ),
                        ),
                    ),
                ),
            )));
