[Resolved] Filter Options Not Working on Translated Archive Page (JetEngine Custom Fields)

Hey, yes I still need assistance. I tried the solution of Bigul but it's too complex for me and I don't know exactly if I'm doing things good or not. That's why I contact again.

But what I need is the step by step explanation for what to do to fix all this. Can you see the previous topic we talked about? That's basically the same.

That's why I message you Bigul, I don't know if it worked and if these are the steps for all problems I have...

1. The first problem still occurring is that on the English filter of the 'Daypart' it gives the Dutch and English options (see attached image 1).

2. The second problem still occurring is that the English 'Age' filter doesn't give all options, just three. And all of those options don't work, they don't show any course. See attached image 2.

3. The third problem still occurring is that the English filter 'Course duration' shows both the Dutch and English options, both with some courses showing. That should be just the English version of course. See attached image 3.

4. The fourth problem which I kind of solved is that the teachers don't show when filtered on the English version. But when I save these courses in English again and fill in the teacher again, they do show. So that's just some work to save these again.

But I tried that with 'Daypart', 'Age' and 'Course duration' as well, but there are just the Dutch options to choose from. See attached image 4.

What's going wrong? What can I change, exactly, to solve this problem. Before I manually go and change all courses, I want to know this because otherwise it will be double the work for doing it again later.

Hi Bigul,

Thanks again for all your support so far. After following your steps for the Weekdag filter, I’ve applied the same logic to the following custom fields:

- tijdstip-overdagavond_course (Daypart)
- duur_course (Course Duration)
- leeftijdscategorie_course (Age Category)
- docent_course (Teacher)

I’ve renamed the field IDs, updated the filters to use these new IDs, set their translation preference to “Copy” in WPML → Settings → Custom Fields Translation, and translated the option labels manually using String Translation (not glossary).

So far:

- The filter labels now appear correctly in English (e.g., “Daytime” instead of “Overdag”).

- The frontend filter UI shows the correct English options.

However, the filter functionality is still not fully working in English. Here's a breakdown of the issues:

Main Problems Still Occurring

1. Course field values in English are not saved properly
When I open the English version of a course (e.g. “Test Page 2 Anne”) and select a value like 12–14 years for leeftijdscategorie_course, it saves successfully at first and appears on the frontend.

But if I refresh the backend editor page, the value is gone again (emptied).

Even worse: on the frontend the old value (e.g. 18–24 years) is still shown, even after saving new input.

2. Filters in English return no results unless I resave the English course
I have to manually open and resave each course in English, otherwise filters like “Daypart” or “Course Duration” return no results.

Even after doing that, some filters still return outdated values or nothing at all.

3. Teacher filter (docent_course) does not show courses in English
Even when the English version of the teacher exists and is properly selected in the English version of a course, the teacher filter in English returns no results.

If I use a Dynamic Field widget to show the docent_course value, it appears on the page — but filtering still fails.

What I've Done:

Renamed all custom field IDs to end in _course, to ensure uniqueness.

Updated the filters’ Query Variables to match the new field IDs.

Set all field translation methods to Copy (not Translate).

Used Dynamic Fields (where possible) to output label instead of value.

Translated option values via WPML → String Translation.

Tried enabling “Get Choices from Field Data” with JetEngine source — this fixed display, but not filtering.

Re-saved English versions of several courses for testing.

What I Need Help With:

Why are some field values not persisting (e.g., leeftijdscategorie_course) when saving in English?

Why do the filters return no results even though the values appear to be set correctly?

Is there any extra WPML setting I need to activate for filters to read and recognize copied custom fields in the translated posts?

Could this be a compatibility issue between JetEngine’s relation fields or post object fields and WPML?

Let me know if you need admin access or if I should record a screencast to show the behavior.

Thanks again,
Jeffrey

Hi Bigul,

So every teacher will work automatically now? So every new created post, existing post and after updating a post? And how about the other filters? Everything working now?

And about the EN flag switcher, why isn't that working properly all the time?

Thanks for the fast response this time, I appreciate you working on it.

Jeffrey

Hey Bigul, perfect. But now it works on the staging environment, not on the live site. What do we have to change to make it work on the live site?
