Get variable defined in service from another controller - php

Question

I will go straight to the point
I have these 2 simple controllers:
/**
* #Route("/controller1", name="controller1")
*/
public function controller1(UserVerification $verification)
{
$verification->setVerificationCode();
return $this->render('user_settings/settings.html.twig');
}
/**
* #Route("/controller2", name="controller2")
*/
public function controller2(UserVerification $verification)
{
$verificationCode = $verification->getVerificationCode();
return $this->render('user_settings/settings.html.twig', [
'verificationCode' => $verificationCode
]);
}
And these two methods in my UserVerification Service:
public function setVerificationCode(){
$this->verificationCode = rand(100000, 999999);
return $this;
}
public function getVerificationCode(): int
{
return $this->verificationCode;
}
My question is: Is that real to get verificationCode in controller2 which has been set in controller1? For now in that example above in controller1 when i use method getVerificationCode() it's successfully returning some random code, but of course in controller2 it's returning null. Is there a way to share service instance?
Thanks for any advice

Answer 1

Here is the point:
In Symfony , by default , services are shared , that mean the same instance is working for many request , if you want the contrary you can modify it in service declaration of your service like :
# config/services.yaml
services:
App\SomeNonSharedService:
shared: false
# ...
But , here , it's different , you function is returning a random value , so even you are using the same service instance , it's sure that you will not have the same result , so here you can do 2 thing :
1- save data into session in case this logic concerns user when is logged in :
2- save data into the dababase
For the two solutions , you have for exmaple to verify if the value already exist into session/DB , like for the first this , it's your service that occur the result , and in the sametime store the value samewhere , so the next request , it will receive data from where you sotre it .
here is an example if you are using Session :
# config/services.yaml
services:
App\Services\CodeService:
arguments:
- "#session"
ServiceCode :
<?php
namespace App\Services;
use Symfony\Component\HttpFoundation\Session\Session;
class CodeService
{
private $session;
public function __construct( Session $session)
{
$this->session = $session;
}
pulic function setVerificationId(){
if(isset(!$this->session->get('verificationCode'))){
$this->session->set('verificationCode', rand(100000, 999999));
}
return this->getVerificationId();
}
public function getVerificationId()
{
return $this->session->get('verificationCode');
}
}
This case is working only if you are using session , if not , do the
same thing using EntityManager to store data somewhere in database.
Hope that help you.
