form – Madisoft S.p.A.

Today we are going to tackle a problem that I’ve recently faced with Symfony form types. Scenario: I need a choice type of a certain entity (Foo) with values that follows a certain logic

<?php

class FooChoiceType extends AbstractType
{
    private $fooAdapter;

    public function __construct(FooAdapter $fooAdapter)
    {
        $this->fooAdapter = $fooAdapter;
    }

    function configureOptions(OptionsResolver $resolver)
    {
        $resolver->setDefaults([
            'required' => true,
            'multiple' => false,
            'choices' => $this->fooAdapter->getFoos(),
        ]);
    }

    public function getParent()
    {
        return ChoiceType::class;
    }
}

<?php

class FooChoiceType extends AbstractType

{

private $fooAdapter;

public function __construct(FooAdapter $fooAdapter)

{

$this->fooAdapter = $fooAdapter;

}

function configureOptions(OptionsResolver $resolver)

{

$resolver->setDefaults([

'required' => true,

'multiple' => false,

'choices' => $this->fooAdapter->getFoos(),

]);

}

public function getParent()

{

return ChoiceType::class;

}

I’ve built up a FooChoiceType because I don’t want to inject fooAdapter in each form where I’m…

Suppose that we have a value object or, more in general, an object where its data has been set in the constructor

class Foo
{
  protected $bar;

  protected $foobar;

  public function construct($bar, $foobar)
  {
    // ....
  }
}

class Foo

{

protected $bar;

protected $foobar;

public function construct($bar, $foobar)

{

// ....

}

and its FormType

class FooType extends AbstractType
{
  public function buildForm(FormBuilderInterface $builder, array $options)
  {
    $builder
      ->add('bar')
      ->add('foobar');
  }
  
  // ...
}

class FooType extends AbstractType

{

public function buildForm(FormBuilderInterface $builder, array $options)

{

$builder

->add('bar')

->add('foobar');

}

// ...

}

Let’s assume that bar and foobar are taken from HTTP POST values (so, basically, we need those values to be posted in order to instantiate a Foo object). Question How can I create…
