问题
I want to pass data from a simple HTML form to a controller through Ajax, then process the data and return a response back.
At the moment I have the following:
HomePage.ss
<form method="POST" class="form-horizontal submit-form" onsubmit="return checkform(this);">
<!-- Text input-->
<div class="form-group">
<label class="col-md-4 control-label" for="name">Name</label>
<div class="col-md-8">
<input id="name" name="name" type="text" placeholder="insert full Name" class="form-control input-md" required="" />
</div>
</div>
<!-- Button -->
<div class="form-group">
<label class="col-md-4 control-label" for="send-btn"></label>
<div class="col-md-8">
<button id="send-btn" name="send-btn" class="btn btn-primary">Submit</button>
</div>
</div>
</form>
JavaScript
$('form.submit-form').submit(function() {
$.ajax({
type: 'POST',
url: 'processForm',
data: $(this).serialize(),
success: function(data) {
alert('data received');
}
});
});
HomePage.php
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';
}
}
}
In developer tools I can see that I got the xhr processForm with a 404 not found error.
How do I get this Ajax form working correctly with the SilverStripe controller?

Spider,
I've done something similar to below. This is a quick and dirty demo and hasn't been tested, but it may get you going in the right path. If you're unfamiliar with how forms work within SilverStripe there is a lesson for front end forms in SilverStripe. I've found the lessons useful personally and provide the code for the lesson as well: http://www.silverstripe.org/learn/lessons/introduction-to-frontend-forms?ref=hub
Page.php
<?php
class Page extends SiteTree
{
}
class Page_Controller extends Content_Controller
{
private static $allowed_actions = array(
'MyForm',
);
public function MyForm()
{
Requirements::javascript(THIRDPARTY_DIR . '/jquery/jquery.min.js');
Requirements::javascript(THIRDPARTY_DIR . '/jquery-validate/jquery.validate.min.js');
Requirements::javascript('/path/to/your/validation/script.js');
$fields = FieldList::create(
TextField::create('name')
->setTitle('Name')
);
$actions = FieldList::create(
FormAction::create('doSubmit')
->setTitle('Submit')
);
$requiredFields = RequiredFields::create(
'name'
);
$form = Form::create($this, 'MyForm', $fields, $actions, $requiredFields);
return $form;
}
public function doSubmit($data, $form)
{
//process $data or create your new object and simpley $form->saveInto($yourObject); then $yourObject->write()
//then deal with ajax stuff
if ($this->request->isAjax()) {
return $this->customise(array(
'YourTemplateVar' => 'Your Value'
))->renderWith('YourIncludeFile');
} else {
//this would be if it wasn't an ajax request, generally a redirect to success/failure page
}
}
}
YourValidationScript.js
(function ($) {
$(function () {
$('#MyForm_Form').validate({
submitHandler: function (form) {
$.ajax({
type: $(form).attr('method'),
url: $(form).attr('action') + "?isAjax=1",
data: $(form).serialize()
})
.done(function (response) {
$('.content').html(response);
})
.fail(function (xhr) {
alert('Error: ' + xhr.responseText);
});
},
rules: {
name: "required"
}
});
})
})(jQuery);

You need to understand how HTTP request routing is handled in SilverStripe.
When you send request POST /processForm, it is treated as page and managed by ModelAsController. That is why you get 404 error - there is no SiteTree record with URLSegment = processForm.
Solution 1
Use Form object. It creates all routing configuration automatically during runtime. Read more https://docs.silverstripe.org/en/3.3/tutorials/forms/ https://docs.silverstripe.org/en/3.3/developer_guides/forms/
Solution 2
Use this approach, when you really want to go down to the simple one method request handler. Register custom controller and routing.
You specify your route in mysite/_config/routing.yml
--- Name: siteroutes --- Director: rules: processCustomForm: CustomFormController
Handle your request
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 } }
