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)
  {
    // ....
  }
}

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…

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;
  }
}

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…
