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. However also floats/doubles are being accepted by this validation. However, if I change @Assert\Type(type="numeric") to @Assert\Type(type="integer") no input is validated as true. How can I validate my input to be an integer value?

The other problem is, after entering an obviously invalid value (like a string of letters) I receive not only my German error message for Type validation but also the English message 'This value should be a valid number'. Where does this message come from and how can I get rid of it?

Thanks for any help!

You should use @Assert\Type(type="integer") and Assert\Min(0). Also, if my assumption about you using it via forms is correct, then you must use integer form type. Probably you're using number or plain text, that's why all inputs were not accepted.

@Assert\Type(type="integer") is not working. That was the first thing I tried. – sprain May 7 '12 at 14:05
Have you seen second part of answer? What form type are you using for this property? – Paweł Jędrzejewski May 8 '12 at 21:54
Using integer as form field type did the trick. Thanks. – sprain May 17 '12 at 9:24

You can use 

/**
 * @Assert\Regex(pattern="/\d+/")
 */

or create a validator with ctype_digit.

As this is a solution that accepts numbers even using text as the field type, it has the downside that it accepts values like "123ABC". Maybe this pattern would be more useful, as it also does not accept values starting with leading zeros: * @Assert\Regex(pattern="/^([1-9][0-9]*)$/") – insertusernamehere Nov 20 '12 at 10:41
