Symfony2默认数字格式

Question

I want to change the default number format in a Symfony 2 project.

Instead of printing the numbers like 10.55 I want to display the decimal separator as a comma 10,55 .

Not in the a Twig template but in all the forms. If I want to that is a Twig is as easy as use the number_format function .

I've already set my locale in the config.yml file.

Answer 1

You probably are using a number type field in your form type.

So you could use the grouping option:

[...] numbers will be grouped with a comma or period (depending on your locale): 12345.123 would display as 12,345.123.

Your code will look as following:

// src/Acme/MyBundle/Form/Type/MyType.php
namespace Acme\MyBundle\Form\Type;

use Symfony\Component\Form\AbstractType;
use Symfony\Component\Form\FormBuilderInterface;

class MyType extends AbstractType
{
    public function buildForm(FormBuilderInterface $builder, array $options)
    {
        $builder->add('mynumber', 'number', array('grouping' => true));
    }

    public function getName()
    {
        return 'my';
    }
}

(you have the same option when using the money field type)

Answer 2

I also used the 'number' field type but one doesn't need the grouping option in the form type, from what I could test. It is enough to render it in the twig template: see example below where {{ discount.discountRate }} is a float. If you replace it with '75.3869', you will find '75,39'

{# number with 2 decimal places, decimal comma, no thousands separator #}
{{ discount.discountRate|number_format(2, ',', '') }}%
