我使用单个操作来显示和提交使用createFormBuilder构建的表单
public function fooBar(){
// ... creating form and stuff
// on first Request i want to use the FlashBag to hold a "Fill out !" message
// how to if here ? if(first request){
$this->get('session')->getFlashBag()->add('notice', "Fill out!");
// }
if ($form->isValid()) {
$fooService->create($bar);
$this->get('session')->getFlashBag()->clear('notice');
$this->get('session')->getFlashBag()->add('notice', "Succesfully Submitted !");
} else {
$this->get('session')->getFlashBag()->add('notice', "Form is Invalid!");
}
// otherwise i see "Fill Out!" and "Form is Invalid" on the First request when i did not fill out anything yet
}
我希望我的问题是可以理解的,
本质上,如果没有提交表单,则isValid()的计算结果为false,如果提交的表单包含无效的属性,则计算结果为false
我希望在第一次显示表单时显示特定的闪光消息

您可以为此目的检查Request
方法。
// ... creating form and stuff
$request = $this->get('request');
// on first Request i want to use the FlashBag to hold a "Fill out !" message
if ($request->isMethod('GET'))
{
$this->get('session')->getFlashBag()->add('notice', "Fill out!");
}
