Symfony form pills – form type options

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;

}

I’ve built up a FooChoiceType because…

Symfony form pills – Value object

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)

{

// ....

}

and its FormType

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…

Symfony

Don’t rely entity setters (order)

What this code does?

class DateTimeInterval

{

private $from;

private $to;

private $allDayLong;

public function setFrom(\DateTime $from)

{

if ($this->isAllDayLong()) {

$from->setTime(0, 0, 0);

}

$this->from = $from;

return $this;

}

public function getFrom() { ... } // omitted

public function setTo(\DateTime $to)

{

if ($this->isAllDayLong()) {

$to->setTime(23, 59, 59);

}

$this->to = $to;

return $this;

}

public function getTo() { ... } // omitted

public function allDayLong()

{

$this->allDayLong = true;

}

public function isAllDayLong()

{

return $this->allDayLong;

}

It’s a simple class that represent a DateTimeInterval with a flag named allDayLong that let an object of DateTimeInterval class to fill all day. You can see that setFrom and setTo are affected from allDayLong flag: if is set, time of…

PHPSpec – Array of mocks in constructor: a practical example

If you know PHPSpec a bit, you certainly are aware of let function.

function let(EntityManager $em)

{

$this->beConstructedWith($em);

}

that helps you to define “automagic” mocks handled directly by PHPSpec and that you can pass to your example

public function it_use_entity_manager(EntityManager $em)

{

// ...

$em->persist(Argument::any())->shouldBeCalled();

}

If type and name of your mock…

About testing entity state changes (in PHPSpec)

This weekend I was poking into my first PHPSpec tests and I found a real scenario that, I bet, you faced at least once if you do BDD/TDD and so on. I’m talking about testing an object that changes state…
