How to remove a single parameter from a symfony2 request object

Question

I have the following request object and you want to remove 'email_suffix' from the controller before binding to the form. Is it possible?

public 'request' => object(Symfony\Component\HttpFoundation\ParameterBag)[8] protected 'parameters' => array 'registration' => array 'email' => string 's' (length=1) 'email_suffix' => string 'y.com' (length=5) 'password' => string '1234' (length=4) '_token' => string '967d99ba9f955aa67eb9eb004bd331151d816d06' (length=40) 'product_id' => string '2' (length=1) 'product_description' => string '12 month membership' (length=19) 'product_price' => string '6.99' (length=4) 

I tried $request->request->remove("registration[email_suffix]");

I can make a request $ request-> request-> remove ("registration") - this works.

I am currently doing this:

 $requestReg = $request->request->get('registration'); $requestReg['email'] = $requestReg['email'].'@'.$requestReg['email_suffix']; unset($requestReg['email_suffix']); $request->request->set('registration',$requestReg); 

Answer 1

I'm not sure if your call to $request->request is a typo.

You should work with $request->attributes , which represents the ParameterBag class.

If you go through the methods in the ParameterBag , you will see that there is no way to disable the variable inside the array.

It is possible to add and remove parameters from the request object in symfony2. You should look at the ComponeterBag Component , there such a method is called remove($key) , which you need.

So, the solution for your request will be like this if you call it from the controller object:

 $this->get('request')->query->remove('email_suffix');
