now i solved it basically, with
<% control Translations %>,<% if Locale == "locale %> and <% if hasTranslation(locale) %>
my original planning about the "languagebar" drifts a little bit from the result
Step1. "Getting the corect $Link per locale". 'Cause i havent found a function for me, which fits, i made it by using
<% control Translations %>
with that it gets the "correct" $link for each locale unsorted,. To get it "sorted", i made
<% if Locale == "en_GB" %>
<img src... /></a>
and then further the other languages, so it is possible to fix the order of the locales,
But, what is, when there is no Locale Link for this page?
Step2. Pages, without a translation for a locale, it wouldn appear
to check, if a page, has a tranlation for that locale, for example
<% if hasTranslation(de_DE) %>
, if not, link with the "startpage" for this locale
Now it shows, first the links for the pages, with a translation for its locale, and then the links for the pages, without translation for its locale, at which is a link for the "startpage" for this locale.
But, the actually locale is not shown now in the bar.
Step3. displaying of the actual locale
to get this, i inserted before <% control Translations %> has begun, another
<% if Locale == "locale" %>
and at least, there is still a little problem, with hastranslation --> actual locale would be postet twice, therefor i made
<% if Locale != "en_GB" %>
<% if hasTranslation(en_GB) %>
<% else %>
Now, in the language bar, the first locale, which is displayed, is the actual locale. Followed by the Pages, with a Translation for this page, and at least, the pages, without a Translation for this page, and this through the if requests sorted.
As posted it drifts a little bit from my planning. 'Cause i wanted the order of the locales completly fixed (for example, first always locale en_GB then de_DE and so on)
For Sure not the best solution, but a solution,
has somebody an idea for a better solution?
edit(forgotten): in page.php page_Controller
with that, every page "knows" its locale
