In Symfony 4.2, the Validator component has introduced a new DivisibleBy
constraint to check whether one number is a multiple of ("divisible by") some
other number. It's mostly useful for enforcing specific increments on a number:
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 | // src/Entity/Item.php
namespace App\Entity;
use Symfony\Component\Validator\Constraints as Assert;
class Item
{
/**
* @Assert\DivisibleBy(0.25)
*/
protected $weight;
/**
* @Assert\DivisibleBy(
* value = 5,
* message = "This item requires to be stocked in multiples of 5 units."
* )
*/
protected $quantity;
}
|
These constraints ensure that that the weight
of the Item
is provided in
increments of 0.25
(e.g. 0.75
and 4.50
would be correct, but
0.18
or 7.32
wouldn't) and the quantity
must be divisible by 5
(25
and 22,620
would be correct but 12
or 123,456
wouldn't).
