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 setTo(\DateTime $to)

{

if ($this->isAllDayLong()) {

}

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…
