Hi Harald,

I have finally been able to test this new version, and it is correctly displays all languages (including current) and also toggles between 2 digit and 4 digit code.

--- Code: ---  <link href="/en/" rel="alternate" type="text/html" hreflang="en-GB" lang="en-GB" title="Home" />
  <link href="/us/" rel="alternate" type="text/html" hreflang="en-US" lang="en-US" title="Home" />
  <link href="/de/" rel="alternate" type="text/html" hreflang="de" lang="de-DE" title="Startseite" />
  <link href="/fr/" rel="alternate" type="text/html" hreflang="fr-FR" lang="fr-FR" title="Accueil" />
  <link href="/ca/" rel="alternate" type="text/html" hreflang="fr-CA" lang="fr-CA" title="Accueil" />
  <link href="/it/" rel="alternate" type="text/html" hreflang="it" lang="it-IT" title="Pagina iniziale" />
  <link href="/es/" rel="alternate" type="text/html" hreflang="es" lang="es-ES" title="Inicio" />
  <link href="/ru/" rel="alternate" type="text/html" hreflang="ru" lang="ru-RU" title="Главная" />
  <link href="/cn/" rel="alternate" type="text/html" hreflang="zh" lang="zh-CN" title="起始界面" />

--- End code ---

The only issue is now thou, is that not all duplicate languages would need to be 4 digits. You still need at least 1 entry from each language to be purely language (2 digit) and which one this is, could differ from user to user.

For instance in the above, the 2 English entries are United States and Great Britain country targeted. Where having

--- Code: ---  <link href="/en/" rel="alternate" type="text/html" hreflang="en" lang="en-GB" title="Home" />
  <link href="/us/" rel="alternate" type="text/html" hreflang="en-US" lang="en-US" title="Home" />

--- End code ---
would target the en-US spelling to United States, but the en-UK spelling to anyone else that has their system set to English regardless of country.


Not sure how this could be maintained outside of manually changing it like I did in the version prior to this (code I used below).

--- Code: --- } else {
$lang->active = false;
if (($lang->menutitle != '') && ($params->get('alternatetag'))) {
if ($lang->lang_code == 'en-US' || $lang->lang_code == 'fr-CA' ) {
$doc->addHeadLink($lang->link, 'alternate', 'rel', array(
'type' => 'text/html',
'hreflang' => $lang->lang_code,
'lang' => $lang->lang_code,
'title' => $lang->menutitle
));
} else {
$doc->addHeadLink($lang->link, 'alternate', 'rel', array(
'type' => 'text/html',
'hreflang' => substr($lang->lang_code, 0, 2),
'lang' => $lang->lang_code,
'title' => $lang->menutitle
));
}
}
}

--- End code ---

Let me know if there is another aspect of it you would like me to test.

Kind Regards,
Jason

Harald Leithner:
oh ok, then the first language should be the 2 digi version?

Harald Leithner:
Attached is a version that do this.

Hi Harald,

Works perfectly!
This method is great, as it also gives the user control over which language is the default as its based of the "Language Manager > Content" ordering.

If I moved French Canadian above French in the Language Manager -> content ordering, it switched which got the 2 digit or 4 digit ISO, so this is perfect as different users would have different defaults.
Couldn't test what would happen if there were 3 variations of the same language, but assume anything after the first instance would get the 4 digit ISO as well.

Kind Regards,
Jason

Harald Leithner:
Thx the 1.3.2 is released with this change.
