Mastering WooCommerce String Translation: The 'RESEND' Button Dilemma

WooCommerce, as a global e-commerce platform, places immense importance on localization. Yet, as highlighted by a recent user query in the WordPress support forum, translating specific interface strings can sometimes present unexpected challenges. The user, bb, inquired about the translatability of the "RESEND" button text on the My Account page, specifically when a user registers with only an email and receives a temporary password notification.

The core of bb's dilemma was the inability to locate and translate the "RESEND" string using Loco Translate, even after performing a sync. This led to the natural question: "Is the term RESEND hardcoded?" While a temporary JavaScript fix was implemented, the desire for a proper, translatable solution underscores a common pain point for many store owners and developers aiming for a fully localized user experience.

Is the "RESEND" String Truly Hardcoded?

To directly answer bb's question: it is highly improbable that the "RESEND" button text within WooCommerce is truly "hardcoded" in the sense of being an untranslatable, raw string. WooCommerce, being a meticulously developed plugin with a strong focus on internationalization, wraps almost all user-facing strings in translation functions like __('string', 'text-domain') or _e('string', 'text-domain'). If Loco Translate isn't picking it up, it usually points to a specific configuration issue, a caching problem, or a subtle variation in the string's context rather than outright hardcoding.

Common Reasons for Elusive Translation Strings

• Incorrect Text Domain: While most WooCommerce strings use the 'woocommerce' text domain, occasionally strings from extensions, themes, or even specific WooCommerce modules might use a different one.
• Contextual String Variation: The string might not be exactly "RESEND" in isolation but part of a larger phrase, or it might have a unique context that Loco Translate's scanning misses without specific configuration.
• Caching Issues: Server-side caching, object caching, or even browser caching can sometimes prevent translation updates from appearing immediately.
• Loco Translate Configuration: The plugin itself might need a deeper rescan, or its settings for the WooCommerce language pack might be misconfigured.
• String Overridden by Theme or Another Plugin: A theme or another plugin might be intentionally or unintentionally overriding the default WooCommerce string, and that overridden string might not be properly translatable.

Actionable Solutions for WooCommerce Store Owners and Developers

For those encountering similar translation hurdles, here's a step-by-step approach to identify and translate the "RESEND" button text or any other elusive WooCommerce string:

Step 1: Verify Loco Translate Setup and Perform a Thorough Sync

Ensure your Loco Translate setup is correct for WooCommerce:

1. Navigate to Loco Translate > Plugins > WooCommerce in your WordPress admin.
2. Select your target language (e.g., "English (United States)" if you're translating from a base English to a nuanced English, or your specific language like "French (France)").
3. Click the Sync button. This is crucial as it rescans the plugin files for new or updated translatable strings.
4. Use the search bar within Loco Translate to look for "RESEND". Try searching with case sensitivity off, or for parts of the string if the exact phrase doesn't appear.
5. If found, provide your translation and save.
6. Clear any site caches (plugin caches, server caches) and check your My Account page.

Step 2: Advanced String Identification (For Developers)

If Loco Translate still fails, a direct file search can pinpoint the string's origin:

1. Access your website's files via FTP/SFTP or your hosting file manager.
2. Navigate to wp-content/plugins/woocommerce/.
3. Search within the plugin's PHP files for the string "RESEND". You're looking for instances where it's wrapped in translation functions, e.g., __('RESEND', 'woocommerce') or _e('RESEND', 'woocommerce'). This will confirm its translatability and text domain.
4. If you find it, ensure the text domain matches what Loco Translate is configured for.

Step 3: The Robust Solution - Using the gettext Filter

For persistent translation issues, or when you need a programmatic override, the WordPress gettext filter is an incredibly powerful tool. It allows you to intercept and modify any translated string before it's displayed on the frontend.

Add the following code to your child theme's functions.php file:

function custom_woocommerce_resend_translation( $translated_text, $text, $domain ) {
    if ( $domain === 'woocommerce' && $text === 'RESEND' ) {
        // Replace 'YOUR_TRANSLATED_TEXT' with your desired translation for "RESEND"
        $translated_text = 'Envoyer à nouveau'; // Example for French
    }
    return $translated_text;
}
add_filter( 'gettext', 'custom_woocommerce_resend_translation', 10, 3 );

Explanation:

• The gettext filter hooks into the translation process.
• We check if the $domain is 'woocommerce' and if the original $text is exactly 'RESEND'.
• If both conditions are met, we override $translated_text with our custom string.
• Ensure you replace 'Envoyer à nouveau' with your actual desired translation.

Step 4: Moving Beyond JavaScript Fixes

While bb's temporary JavaScript fix offered immediate relief, it's generally not the recommended long-term solution for string translation. JavaScript modifications are client-side, can be brittle with theme or plugin updates, and aren't ideal for SEO or consistent user experience across all browsers and devices. The gettext filter, being a server-side WordPress hook, provides a robust, maintainable, and proper way to handle such translations.

Best Practices for WooCommerce Localization

• Always Use a Child Theme: Any code modifications, including translation filters, should always reside in a child theme's functions.php to ensure they are not overwritten during theme updates.
• Regularly Update Language Packs: Keep your WooCommerce and WordPress language packs updated to benefit from the latest translations and string definitions.
• Understand Text Domains: Familiarize yourself with how text domains work in WordPress. This knowledge is crucial for effective translation.

Conclusion

The "RESEND" button translation query, while seemingly minor, highlights a common challenge in WooCommerce localization. While strings are rarely truly hardcoded, their elusive nature can frustrate. By understanding common causes for translation issues and employing robust solutions like the gettext filter, store owners and developers can ensure a fully localized, professional, and consistent experience for their global customer base, moving beyond temporary client-side fixes to server-side stability.
