如何验证 ZF2 中的复选框 [英] How to validate a checkbox in ZF2

问题描述

我已经阅读了许多针对 Zend Framework 缺少默认复选框验证的解决方法.

I've read numerous workarounds for Zend Framework's lack of default checkbox validation.

我最近开始使用 ZF2，但那里的文档有点缺乏.

I have recently started using ZF2 and the documentation is a bit lacking out there.

有人可以演示我如何使用 Zend 表单和验证机制验证复选框以确保它被选中吗?我正在为我的表单使用数组配置(使用 ZF 网站上示例应用程序中的默认设置).

Can someone please demonstrate how I can validate a checkbox to ensure it was ticked, using the Zend Form and Validation mechanism? I'm using the array configuration for my Forms (using the default set-up found in the example app on the ZF website).

推荐答案

试试这个

表单元素:

$this->add(array(
            'type' => 'Zend\Form\Element\Checkbox',
            'name' => 'agreeterms',
            'options' => array(
                'label' => 'I agree to all terms and conditions',
                'use_hidden_element' => true,
                'checked_value' => 1,
                'unchecked_value' => 'no'
            ),
        ));

在过滤器中，添加数字验证

In filters, add digit validation

use Zend\Validator\Digits; // at top

$inputFilter->add($factory->createInput(array(
                        'name' => 'agreeterms',
                        'validators' => array(
                            array(
                                'name' => 'Digits',
                                'break_chain_on_failure' => true,
                                'options' => array(
                                    'messages' => array(
                                        Digits::NOT_DIGITS => 'You must agree to the terms of use.',
                                    ),
                                ),
                            ),
                        ),
                    )));
