Format WooCommerce currencies per WPML language

readme.md

Problem

Currencies in French are formatted differently to currencies in English:

• English: $00.00, €00.00, £00.00
• French: 00,00 $, 00,00 €, 00,00 £

WPML says the only way to format the same currency in two ways is via string translation of woocommerce_currency_pos, woocommerce_price_decimal_sep and woocommerce_price_thousand_sep – but that it only works for one language/currency combination... :thinking_face: (See https://wpml.org/forums/topic/two-formats-for-same-currency-in-woocommerce-multilingual/ for details.)

Solution

Let's use hooks to manually override the decimal separator, the currency symbol position and the thousands separator for all currencies in French. :dancer:

functions.php

<?php

// Show currency symbol on the right for prices in French language
function filter_currency_pos( $format ) {
  $current_lang = apply_filters( 'wpml_current_language', NULL );
  if ($current_lang == 'fr') {
    $format = '%2$s&nbsp;%1$s';
  }
  return $format;
};

// Use comma as decimal separator for prices in French language
function filter_decimal_sep($decimal_separator) {
  $current_lang = apply_filters( 'wpml_current_language', NULL );
  if ($current_lang == 'fr') {
    $decimal_separator = ',';
  }
  return $decimal_separator;
}

// Use space as thousands separator for prices in French language
function filter_thousands_sep($thousand_separator) {
  $current_lang = apply_filters( 'wpml_current_language', NULL );
  if ($current_lang == "fr") {
    $thousand_separator = ' ';
  }
  return $thousand_separator;
}

add_filter( 'woocommerce_price_format', 'filter_currency_pos' );
add_filter( 'wc_get_price_decimal_separator', 'filter_decimal_sep' );
add_filter( 'wc_get_price_thousand_separator', 'filter_thousands_sep' );
