[Closed] Acf Repeater Field Not translatable in Acf Option Pages

Hi There,
Thanks for reaching out to WPML Support.

Before this thread gets assigned to my colleague, I'd like to offer some initial guidance or potential solutions.

We have identified a problem with the ACF Repeater Subfields on the options page that appears to closely resemble the issue you have described. Could you please try the workaround mentioned in the Errata below and check if it helps in solving the issue?

Hello There,
I hope you're doing well. Sorry for the delay in responding due to the weekend.

I took over this ticket and will try my best to assist you in this matter.

The translation preference for the repeater field can be configured based on the Translation option selected for the Field group. First, you need to set the Translation Mode for the field group containing the repeater fields to "Expert." Once this is done, you'll be able to set the translation preference for the Repeater field to "Copy-Once." Here are the steps to follow:

- Open the Field group that contains the Repeater field.
- At the top of the Field group, you'll find a section to set the Translation option. Choose the 'Expert' option for the Field group and save your changes.
- The Field group will reload. Next, open the Repeater field, and you'll see an option to set the translation preference directly from the Field group edit screen. Set the preference for the Repeater field to "Copy-Once."
- Set the translation preference to the Sub fields to "Translate" or as per your needs and save the changes.

Hopefully, the steps above will help in solving the issue. Please feel free to let me know if you need further assistance in this matter. I will be happy to help.

Best regards,

Hi!
Thank you for sharing access to your testing site.

I checked and have successfully been able to fix the issue there. The translation preference for the ACF field is totally correct but, The issue was mainly happening due to a custom code defined in the functions.php file of the theme. The else condition within the 'fix_post_id_on_preview' function is mainly causing the issue.

Let me share what that code was doing. The custom code was designed to adjust how the post ID is handled during previews, making sure the right content is shown. However, it didn’t account for the options page, which led to unintended changes.

To fix the issue, I modified the `else` condition in the code, adding a check to determine if it’s dealing with an options page. If it is, the code now skips any changes to prevent overwriting. Below is the updated `fix_post_id_on_preview()` function that includes the changes to solve the problem.

function fix_post_id_on_preview($null, $post_id) {
    if (is_preview()) {
        return get_the_ID();
    }
    else {
    // Ensure the post ID is correctly handled
    $acf_post_id = is_object($post_id) && isset($post_id->ID) ? $post_id->ID : $post_id;

    // If the post ID is valid and not an options page, return it
    if (!empty($acf_post_id) && strpos($acf_post_id, 'options') === false) {
        return $acf_post_id;
    }

    // Otherwise, return null to avoid issues
    return $null;
}

}

I thoroughly tested the solution and can confirm that the options page content in other languages is no longer being overwritten. Please replace the `fix_post_id_on_preview` function in the functions.php file on your main site with the updated code provided above. After doing so, update the default options page first, and then proceed to translate the options page.

I hope this solution helps. While providing support for issues arising from custom coding is beyond the scope of our usual support, I wanted to share this fix because a simple check resolved the issue. If you need further assistance with custom code, I recommend consulting with the theme developer or considering hiring a developer from our certified contractor list.

Let me know if you have any other questions or need clarification. I will be happy to help.
