php – 使用symfony2使用GET方法从表单中检索数据
作者:互联网
我无法从我的表单中检索数据,我尝试了不同的方法,但没有结果.我的存储库:
public function buildForm(FormBuilderInterface $builder, array $options)
{
$builder->add('min_price', 'text', array('mapped' => false, 'label' => 'De la :', 'attr'=>
array(
'placeholder'=>'Pretul minim',
'class'=>'form-control')))
->add('max_price', 'text', array('mapped' => false, 'label' => 'Pina la :' , 'attr'=>
array(
'placeholder'=>'Pretul maxim',
'class'=>'form-control')))
)
;
}
public function setDefaultOptions(OptionsResolverInterface $resolver)
{
parent::setDefaultOptions($resolver);
$resolver->setDefaults(array(
// avoid to pass the csrf token in the url (but it's not protected anymore)
'csrf_protection' => false,
));
}
public function getName()
{
return '';
}
我的控制器:
public function showCategoryAction($id, $page, Request $request){
$em = $this->getDoctrine()->getManager();
$repositoryProduct = $em->getRepository('ShopDesktopBundle:Product');
$category = $em->getRepository('ShopDesktopBundle:Category')->findOneById($id);
if (!$category) {
throw $this->createNotFoundException('Category not found.');
}
$aFilter = array();
$entity = new Product();
$form = $this->createForm(new ProductType(), $entity,array(
'action' => $this->generateUrl('show_product_category',array("id" => $id, "name" => $category->getCategoryLink(), "page" => $page )), //Your url to generate
'method' => 'GET'
));
$form->handleRequest($request);
$aFilter['iMinPrice'] = $form["min_price"]->getData();
$aFilter['iMaxPrice'] = $form["max_price"]->getData();
print_r($aFilter);
//Searchs products
$aProducts = $repositoryProduct->getProductsOrderByDateDesc($id,null,$aFilter);
if (!$aProducts) {
throw $this->createNotFoundException('Products not found.');
}
//Create pagination
$paginator = $this->get('knp_paginator');
$pagination = $paginator->paginate(
$aProducts,
$page,
3
);
//Send data to view
return $this->render('ShopDesktopBundle:Category:category.html.twig',array(
'category' => $category,
'pagination' => $pagination,
'form' => $form->createView()
));
}
我的看法 :
<form action="{{ path('show_product_category',{ 'id':category.getId(), 'name':category.getCategoryLink() }) }}" method="get" {{ form_enctype(form) }}>
<div class="accordion-group">
<div class="accordion-heading">
<a class="accordion-toggle" data-toggle="collapse" data-parent="" href="#toggleOne">
<em class="icon-minus icon-fixed-width"></em>Pret
</a>
</div>
<div id="toggleOne" class="accordion-body collapse in">
<div class="accordion-inner">
{{ form_widget(form) }}
</div>
</div>
</div>
<input type="submit" class="btn btn-primary marg-left-20" value="Cautare"/>
</form>
风景 :
show_product_category:
path: /{id}/{name}/{page}
defaults: { _controller: ShopDesktopBundle:Category:showCategory, page: 1}
requirements:
id: \d+
page: \d+
_method: GET|POST
所以问题是我无法从该表单中检索数据.对于所有情况,$aFilter为空.例如,如果我在表单POST方法中放入视图,则过滤器使用表单中的数据.我的网址看起来像这样:
?MIN_PRICE = 10安培; MAX_PRICE = 50.
请帮帮我. Thx提前.解决方案?
解决方法:
我不会将表单方法设置为GET,只是不指定方法,它将默认为POST,这是提交表单的常用方法.
然后在方法POST时在Controller中处理表单提交 – 如下所示:
if ($request->isMethod('POST')) {
$form->handleRequest($request);
if ($form->isValid() {
$aFilter['iMinPrice'] = $form->get('min_price')->getData();
$aFilter['iMaxPrice'] = $form->get('max_price')->getData();
}
}
有关如何在Symfony2 here中处理表单提交的更多信息.
如果你真的需要表单方法是GET,你应该能够从请求中获取查询字符串参数:
$aFilter['iMinPrice'] = $request->query->get('min_price');
$aFilter['iMaxPrice'] = $request->query->get('max_price');
