Symfony-Ajax表单验证-额外数据

Question

I need to send a data from a Symfony form with an Ajax call with an extra Data containing options for the controller.

I'm working on a custom framework including the Symfony form component.

So I try in my JS to send values like this :

$.ajax
(
    {
        type: "POST",
        url: '/myUrl',
        data: 
        {
            'formData' : $(this).serialize(),
            'extraData' : {'test1' : 'test1', 'test2' : 'test2'}
        },
        success: function(result)
        {
            // do something
        }
    }
);

How can I get my form data in my controller to let the component correctly understand it ? This code won't work :

$formData = $this->getRequest()->request('formData');
$form->bind($formData);

Thank you. I hope my question is clear enough

Edit: I finally integrated the data into hidden fields in my form. The form doesn't declare any data_class, as the ORM we use is a really custom one. Thanks for the answers

Answer 1

try $form->submit($formData);

Answer 2

If your form has a data_class option, you can't bind / handle the request directly with extra_values.

Your form expects the variables that you already defined on your formtype.

Use it like this:

if($request->isXmlHttpRequest()) {
    $form->handleRequest($request);

    if($form->isValid()) {
        // To get extra data;
        $extra_data = $request->request->get('extraData');
    }
}
