我想通过Ajax将数据从简单的HTML表单传递给控制器,然后处理数据并返回响应。
目前我有以下内容:
HomePage.ss
$('form.submit-form').submit(function() {
$.ajax({
type: 'POST',
url: 'processForm',
data: $(this).serialize(),
success: function(data) {
alert('data received');
}
});
});
的JavaScript
class HomePage_Controller extends Page_Controller {
public function events() {
$events = CalendarEvent::get();
return $events;
}
public function processForm() {
if (Director::is_ajax()) {
echo 'ajax received';
} else {
//return $this->httpError(404);
return 'not ajax';
}
}
}
HomePage.php
application/libraries
在开发人员工具中,我可以看到我得到了xhr processForm,其中找不到404错误。
如何使用SilverStripe控制器正确使用此Ajax表单?

蜘蛛,
我做过类似下面的事情。这是一个快速而肮脏的演示,尚未经过测试,但它可能会让您走上正确的道路。如果您不熟悉SilverStripe中表单的工作方式,那么SilverStripe中的前端表单会有一课。我发现这些课程对个人有用,并为课程提供了代码:http://www.silverstripe.org/learn/lessons/introduction-to-frontend-forms?ref=hub

您需要了解如何在SilverStripe中处理HTTP请求路由。
当您发送请求POST / processForm时,它被视为页面并由ModelAsController管理。这就是为什么你得到404错误 - 没有使用URLSegment = processForm的SiteTree记录。
解决方案1
使用表单对象。它在运行时自动创建所有路由配置。阅读更多 https://docs.silverstripe.org/en/3.3/tutorials/forms/ https://docs.silverstripe.org/en/3.3/developer_guides/forms/
解决方案2
当您真正想要使用简单的方法请求处理程序时,请使用此方法。注册自定义控制器和路由。
您可以在mysite / _config / routing.yml
中指定路线---
Name: siteroutes
---
Director:
rules:
processCustomForm: CustomFormController
处理您的请求
class CustomFormController extends Controller
{
public function handleRequest( SS_HTTPRequest $request, DataModel $model ) {
if (!$request->isPost()) {
// handle invalid request
}
$name = $request->postVar('name')
// process your form
}
}
