带有 html5 和 CANCEL 按钮的 Symfony2 表单验证 [英] Symfony2 form validation with html5 and CANCEL button

问题描述

我在 Symfony2 上有一个联系表，我在其中放置了一些验证器，例如电子邮件、minLength 等.所有这些字段也都设置为 notBlank.

I have a contact form on Symfony2 where I put some validators as email, minLength etc. All those fields are also set as notBlank.

因此，HTML5 也在验证这些字段(用于电子邮件而不是空白)，这对我来说很好.

Due to this, HTML5 is also validating those fields (for the email and not blank), which is fine for me.

我有一个提交按钮:

<input type="submit" value="Submit"/>

问题是我有另一个提交按钮，它是一个取消按钮:

The problem is that I have another submit button which is a Cancel button:

<input name="cancel" type="submit" value="Cancel" />

使用这个按钮，我在我的控制器中进行重定向:

With this button, in my controller I am doing a redirect:

if( $request->get('cancel') == 'Cancel' )
    return  $this->redirect($this->generateUrl('SciForumVersion2Bundle_homepage'));

现在，由于 HTML5 验证，我无法重定向，因为例如字段为空.

Now, due to the HTML5 validation, I can't redirect because the fields are empty for example.

为了解决这个问题，我找到了两个解决方案，但我不喜欢它们:

To reslove that, I have found two solutions, but I don't like them:

1. 禁用 HTML 5 验证:

1. Disable the HTML 5 validation:

<form novalidate>

使用 JavaScript

Use JavaScript

但正如我所说，我不喜欢那些方法，我确信有一些不错的 Symfony 方法可以解决这个问题.

But as I said, I don't like those methods and I am sure that there are some nice Symfony methods to resolve that.

有什么想法吗?非常感谢.

Any idea? Thank you very much.

推荐答案

我继续我的评论:)

当处理表单(HTML5 或非 HTML5)并且您想退出时，您不需要提交和验证任何数据您只需放置一个简单的 href 链接即可更改页面.使用您喜欢的 css 样式来获得相同的外观

when dealing with form (HTML5 or not) and you want to quit, you don't need to submit and validate any data You just have to put a simple href link to change the page. Use your favorite css style to have the same look

提示:当用户更改输入值时，您可以监听 javascript 事件 "onbeforeunload".它提醒用户他将退出页面

Tip: you could listen to javascript event "onbeforeunload" when user has changed an input value. It alerts the user that he will quit the page
