Pluralising with Twig

pluralise.twig

{% spaceless %}
{% if integer > 1 %}
  {{ plural }}
{% else %}
  {{ singular }}
{% endif %}
{% endspaceless %}

Usage:

{% include 'pluralise.twig' with {
  integer: post.bed_count,
  plural: 'bedrooms',
  singular: 'bedroom'
} %}

Or try this:

{{ post.bed_count }} {{ _n( 'bedroom', 'bedrooms', post.bed_count ) }}

@Machou whatever application you're working in probably doesn't have this function included. For example WordPress comes with this function available and therefore available in Twig

Hello, here is my implementation via a twig filter, a bit inspired by AngularJS's ngPluralize filter.

{{nbMessages | pluralize ('{} message', '{} messages')}} // 0 message, 1 message, 2 messages
{{nbMessages | pluralize ('{} message', '{} messages', 'no message')}} // no message, 1 message, 2 messages

<?php

namespace App\Twig;

use Twig\Extension\AbstractExtension;
use Twig\TwigFilter;

class AppExtension extends AbstractExtension
{
  public function getFilters(): array
  {
    return [
      new TwigFilter('pluralize', [$this, 'pluralize'])
    ];
  }

  public function pluralize(int $count, string $singular, string $plural, string $zero = null): string
  {
    if ($count > 1){
      return str_replace('{}', $count, $plural);
    } else if ($count <= 0 && null !== $zero){
      return $zero; // No string replacement required for zero
    }
    return str_replace('{}', $count, $singular);
  }
}
