[Resolved] Strings not updating on the front end, after being translated

This thread is resolved. Here is a description of the problem and solution.

Problem:
The client is facing an issue where the translated strings for different payment options in the checkout are not displaying on the front end after updating plugins. The issue is specific to the WooCommerce Blocks checkout, where the plugin does not call WPML translation filters.
Solution:
We identified that the plugin was returning the raw option value without passing it through WPML's translation filters. To resolve this, we modified the plugin file to ensure that the title and description are translated before being sent to the checkout block. Here are the steps we took:

  • Navigate to 
    wp-content/plugins/multibanco-ifthen-software-gateway-for-woocommerce/woocommerce-blocks/MultibancoIfthenPay.php
  • Replace the existing 
    get_payment_method_data()

    function with the new code that includes WPML translation filters for the title and description.

  • Go to WPML --> String Translation and translate the strings again.

This should ensure that the payment method descriptions appear translated in the WooCommerce Blocks checkout. We also recommend informing the plugin author about this issue for a permanent fix.

Please note that this solution might be outdated or not applicable to your specific case. We highly recommend checking related known issues, verifying the version of the permanent fix, and confirming that you have installed the latest versions of themes and plugins. If the issue persists, please open a new support ticket.

Background of the issue:
I am trying to get support for the payment method selection block on my site hidden link. I have translated the strings in WPML and ensured all related plugins are updated.

Symptoms:
The translations for the different payment options in the checkout are not displaying on the front end. After the update, the icon for each language shows the pencil (which seems correct), but after refreshing the page it changes back to the icon shown in the attached image.

Questions:
Why are the translated strings for payment options not displaying on the front end?

Hi there!

I see that the strings that doesn´t appear translated are the ones that comes from the plugin: Multibanco, MB WAY, Credit card, Apple Pay, Google Pay, Payshop, Cofidis Pay, and PIX (ifthenpay) for WooCommerce

Could you please install the plugin in the following test site?
hidden link

That way I can see if I can reproduce the issue.

Please let me know when it is done.

Ok, as I need a valid license in order to activate Multibanco.

Would you allow me to download a copy of your site to test it locally?
Alternatively, do you already have a staging site where I could run some tests safely without affecting your live site?

I see that there is a new version of the plugin.

Could you please update it first and re-translate the string and let me knoe if the issue is fixed?

Hello Paola,

We have already updated the plugins, including Ifthenpay (where those strings are located), but the issue persists. New ones appeared, I did a rescan for possible new strings, but nothing changed, the error remains.

Is there any way we can ensure that these texts appear in the other languages? This point is extremely important for our website’s conversion, since the payment names and texts (at checkout) are in another language and may generate mistrust (for example with the “Multibanco” option).

Thank you very much, I look forward to your feedback.

I don´t have access anymore to the site.

In order to continue the investigation, I would like to request access (wp-admin and FTP) to your site, please add also FTP access so I can have a look to the files for that plugin.

I have enabled next answer as private.

Thanks.

I have deleted the access as you added on a public way.

Hi there!

I have found the issue and was on the plugin code.

The reason why the payment method description was not showing translated is that the plugin was returning the raw option value in the WooCommerce Checkout Blocks, without calling WPML translation filters.

In the classic checkout (shortcode) it works, because WPML intercepts get_option().
But in the Blocks checkout, the plugin must explicitly pass the strings through wpml_translate_single_string().

We modified the plugin file so that the title and description are translated before being sent to the checkout block.

In order to solved it this is what I have done:
- go to wp-content/plugins/multibanco-ifthen-software-gateway-for-woocommerce/woocommerce-blocks/MultibancoIfthenPay.php
- change this code

public function get_payment_method_data() {
    return apply_filters(
        'multibanco_ifthen_blocks_payment_method_data',
        array(
            'title'       => isset( $this->settings['title'] ) ? $this->settings['title'] : '',
            'description' => isset( $this->settings['description'] ) ? $this->settings['description'] : '',
            'icon'        => WC_IfthenPay_Webdados()->multibanco_icon,
            'icon_width'  => 28,
            'icon_height' => 24,
        )
    );
}

- to this one:

public function get_payment_method_data() {
    $title       = isset( $this->settings['title'] ) ? $this->settings['title'] : '';
    $description = isset( $this->settings['description'] ) ? $this->settings['description'] : '';

    // Pass strings through WPML translation
    if ( function_exists( 'apply_filters' ) ) {
        $title = apply_filters(
            'wpml_translate_single_string',
            $title,
            'admin_texts_woocommerce_multibanco_ifthen_for_woocommerce_settings',
            'title'
        );
        $description = apply_filters(
            'wpml_translate_single_string',
            $description,
            'admin_texts_woocommerce_multibanco_ifthen_for_woocommerce_settings',
            'description'
        );
    }

    return apply_filters(
        'multibanco_ifthen_blocks_payment_method_data',
        array(
            'title'       => $title,
            'description' => $description,
            'icon'        => WC_IfthenPay_Webdados()->multibanco_icon,
            'icon_width'  => 28,
            'icon_height' => 24,
        )
    );
}

- then go to WPML --> String translation and translate again the string
- then it will appear translated

I recommend you to update the plugin author if it is happening on other strings.
