Annotations

// src/AppBundle/Entity/Author.php

use Symfony\Component\Validator\Constraints as Assert;

class Author
{
    /**
     * @Assert\Url(
     *    message = "The url '{{ value }}' is not a valid url",
     * )

     protected $bioUrl;
}

    properties:
        bioUrl:
            - Url:
                message: The url "{{ value }}" is not a valid url.

            'message' => 'The url "{{ value }}" is not a valid url.',
        )));
    }
}

protocols¶

type: array default: array('http', 'https')

The protocols considered to be valid for the URL. For example, if you also consider the ftp:// type URLs to be valid, redefine the protocols array, listing http, https, and also ftp.

// src/AppBundle/Entity/Author.php
namespace AppBundle\Entity;

use Symfony\Component\Validator\Constraints as Assert;

class Author
{
    /**

     protected $bioUrl;
