Hi,

Which extra fields are used for? for articles, menu items or modules. As for each content type, the extra fields adding process is a little bit different.

Regards.

Extra fields are for com_content

The extra fields if they work, which is not working is translation.
example:
In myextrafields.xml

label = "EXTRA_AUTHOR_NAME_LABEL"

In en-GB.tpl_template_name.ini

 EXTRA_AUTHOR_NAME_LABEL = "Extra Name"

In my admin I still see EXTRA_AUTHOR_NAME_LABEL
But when I think the com_content.article.xml file in the etc/FORM folder, there if the translation works

But I do not need the file com_content.article.xml

So the question is: This works well? T3 error?

Please add the language string to the file: In en-GB.tpl_template_name.sys.ini in folder: language\en-GB
The file includes languages on back-end, the file you added is for front-end.

Regards.

Of course that's logical.

My questions are not because they can not solve; but because in some cases it works, and not in others.

Examples:

CASE 1

I think an extra field: /etc/form/com_componentname.view (view = article, product, category, item, etc.).
And translation in: /language/en-GB/en-GB.tpl_template_name.ini. The translation works perfect.

CASE 2
I think an extra field: /etc/extrafields/extrafieldgroup.xml
And translation in: /language/en-GB/en-GB.tpl_template_name.ini. The translation is not working.

For case 2, the solutions would be:
a) the translation in template_name.sys.ini. Which is incorrect and translation would not work in Front-End. And create the same translation in template_name.ini to work in front-end makes no sense.

b) create the file: /etc/form/com_componentname.view.xml. with the following code:

<?xml version="1.0" encoding="utf-8"?>

<form></form>

Note: I've seen those Joomlart make the translation to extra fields in template_name.ini; but always use the /etc/form/com_componentname.view.xml(com_content.article.xml file). I would like to do only with /etc/extrafields/extrafieldgroup.xml tests; And see if there is a solution to that little problem.
