Validation an integer input from a form

Question

I have an entity with several fields in it. One of them is being validated after form submission as follows: ``` /** * @var integer $anzahl * * @ORM\Column(name="anzahl", type="integer") * @Assert\NotBlank(message="Bitte geben Sie eine Kistenanzahl an.") * @Assert\Type(type="numeric", message="Die Kistenanzahl muss eine Zahl sein.") * @Assert\Min(limit="1", message="Sie müssen mindestens eine Kiste suchen oder anbieten.") */ private $anzahl; ``` I am having two problems with this solution: Only integer values higher than zero should be accepted.

Accepted Answer

You should use:

```
@Assert\Type(type="integer")
```

But be careful, you should use it with an `IntegerType`, not a `NumberType` or a `TextType`:

```
Symfony\Component\Form\Extension\Core\Type\IntegerType 
```

`IntegerType` is identical to `NumberType` except that it integrates the proper data transformer.
