Symfony validate entity using form - php

Question

$userData = (new User())
->setPersonCode(123)
->setPhone('[phone]');
$userForm = $this->toolbar->getForm(UserType::class, $userData);
I'm creating form from entity class where is setted data. If now I try use:
$userForm->isValid();
I'm getting true, because form data is not submitted, how I can do validation, without setting manually data to form and submitting ?

Answer 1

If you don't want to submit data to a form, skip forms entirely; use the Validator service directly:
<?php
// (Assuming you're in a controller, otherwise inject the validator some other way.)
$userData = (new User())
->setPersonCode(123)
->setPhone('[phone]');
$validator = $this->get('validator');
$errors = $validator->validate($userData);
$isValid = count($errors) === 0;

Answer 2

Your question is worded a little strange and im not sure exactly what you want, If you want to manually set the data like above then call $form->submit() passing the user data.
$userData = (new User())
->setPersonCode(123)
->setPhone('[phone]');
$userForm = $this->toolbar->getForm(UserType::class);
$userForm->submit($userData);
if(!$userForm->isValid()){
// handle errors
}
If you want to have the user submit data on a form then do something like this:
public function createUserAction(Request $request)
{
$userForm = $this->toolbar->getForm(UserType::class);
$userForm->handleRequest();
if(!$userForm->isValid()){
// handle errors
}
}
$userForm->handleRequest(); will handle taking data that was submitted from the form on the page.
