Conditional validation of fields based on other field value in Symfony2

Question

So here is the scenario: I have a radio button group. Based on their value, I should or shouldn\'t validate other three fields (are they blank, do they contain numbers, etc)

I suggest you to use a callback validator.

For example, in your entity class:

getRadioSelection() == '1' // RADIO SELECT EXAMPLE
                &&
                ( // CHECK OTHER PARAMS
                 $this->getFiled1() == null
                )
            )
        {
            $context->addViolation('mandatory params');
        }
       // put some other validation rule here
    }
}

Otherwise you can build your own custom validator as described here.

Let me know you need more info.

Hope this helps.
