如何在symfony2中获取多值get参数的值

Question

How do you get the value for a get parameter that is a list of values? I tried using request->query->get('parameter') but this only returns one value.

Suppose you have a country parameter and want to pass more than 1 value. eg ... ?country=us,gb using get gives you 'us' only.

I can not find this in the docs.

Answer 1

您必须以这种方式格式化查询参数

country[]=us&country[]=gb

Answer 2

From their manual (http://symfony.com/doc/current/book/http_fundamentals.html)

use Symfony\Component\HttpFoundation\Request;

$request = Request::createFromGlobals();

$request->query->get('foo');

Edit:

Sorry, I misunderstood your question. You want an array of all GET valiables like $_GET will give you?

That can be done with (will also include POST parameters):

 <?php $request->getParameterHolder()->getAll();
