Symfony2：如何删除请求参数？

Question

I have this parameters submitted by a form :

myform[field1]: 'text1'
myform[field2]: 'text2'
myform[field3]: 'text3'

Under condition, myform[field3] must not be validated, so i want to remove it.

How can I remove the parameter myform[field3]?

I try a lot of things without success like :

$request->attributes->remove("field3");
$request->request->remove("field3");
$request->request->remove("myform[field3]");

How can I remove this parameter?

Update

In fact $request->request->remove("myform"); is working, but remove all parameters. Is it possible to remove only an element of the array?

I think you're asking the wrong question. What you're really looking for is conditional validation, and there are several options for that
