我正在尝试通过ajax提交表单来更新实体的字段,但不知道如何从控制器检索数据：
<form class="ajax" action="{{ path('ajax_setSocial') }}" method="post" {{ form_enctype(form) }}>
<div class="editor">
{{ form_errors(form) }}
<div class="editLabel pls">{{ form_label(form.ragSocial) }}</div>
<div class="editField">
<div class="ptm">
{{ form_widget(form.ragSocial) }} {{ form_errors(form.ragSocial) }}
</div>
{{ form_rest(form) }}
<div class="mtm">
<button class="btn btn-primary disabled save" type="submit">Save</button>
<button class="btn ann">Close</button>
</div>
</div>
</div>
var url = Routing.generate('ajax_setSociale');
var Data = $('form.ajax').serialize();
$.post(url,Data,function(results){
if(results.success == true) {
$(this).parents('ajaxContent').remove();
$(this).parents('.openPanel').removeClass('openPanel');
} else {
alert('False'); //test
}
});
控制器(ajax_setSocial路由)
public function setSocialeAction(Request $request)
{
$em = $this->getDoctrine()->getManager();
// $id = $request->get('form'); ???
$entity = $em->getRepository('MyBusinessBundle:Anagrafic')->find($id);
if (!$entity) {
throw $this->createNotFoundException('Unable to find Anagrafic entity.');
}
$form = $this->createFormBuilder($entity)
->add('ragSocial','text',array('label' => 'Social'))
->add('id','hidden')
->getForm();
$form->bind($request);
if ($form->isValid()) {
$em->persist($entity);
$em->flush();
$output = array();
$response = new Response();
$output[] = array('success' => true);
$response->headers->set('Content-Type','application/json');
$response->setContent(json_encode($output));
return $response;
}
解决方法
我建议把id传递给控制器.
HTML：
<form class="ajax" action="{{ path('ajax_setSocial',{ 'id': entity.id }) }}" method="post" {{ form_enctype(form) }}>
var url = "{{ path('ajax_setSocial',{ 'id': entity.id }) }}";
控制器注释,参数和返回值,以获取id：
/**
*
* @Route("/{id}",name="ajax_setSocial")
* @Method("POST")
*/
public function setSocialeAction(Request $request,$id) {
$em = $this->getDoctrine()->getManager();
$entity = $em->getRepository('MyBusinessBundle:Anagrafic')->find($id);
return array(
'entity' => $entity
);
}
将错误传回html就是这样的：
// dummy line to force error:
// $form->get('ragSocial')->addError(new FormError("an error message"));
if ($form->isValid()) {
...
} else {
$errors = $form->get('ragSocial')->getErrors(); // return array of errors
$output[] = array('error' => $errors[0]->getMessage()); // the first error message
$response->headers->set('Content-Type','application/json');
$response->setContent(json_encode($output));
return $response;
}
