Issue with Language Association in FLEXIContent – zh-TW tag not mapping to /tw/ URL

[iamrobert]

Hi,

I am experiencing an issue with language association in Joomla using FLEXIContent. Specifically, the zh-TW language tag does not map correctly to the desired URL language code /tw/. Instead, it defaults to zh. This issue persists

With the latest language file - doesn't allow me to switch URLs.

The URLs for both en-GB and zh-TW are identical in SEF mode. In non-SEF mode, the URL for zh-TW incorrectly includes &lang=en instead of &lang=tw.

Example:
index.php?option=com_flexicontent&view=item&cid=37&id=193&Itemid=1233&lang=en

The URL should be:
index.php?option=com_flexicontent&view=item&cid=37&id=193&Itemid=1233&lang=tw

OLDER VERSION
Reverting to an earlier version of the association helper partially resolves the issue; the URL works with /zh/ but not with /tw/.

Suspected Cause:
It appears that the line $lang_code = substr($tag, 0, 2) is extracting zh as the language code for zh-TW. The following array output showing the language associations:

// Debug: Print the entire associations array
echo "<pre>"; print_r($associations); echo "</pre>";
die;

(
    [en-GB] => stdClass Object
        (
            [language] => en-GB
            [type_id] => 1
            [id] => 178
            [catid] => 33
            [title_slug] => 178:Facilities
            [cat_slug] => 33:facilities
        )

    [zh-TW] => stdClass Object
        (
            [language] => zh-TW
            [type_id] => 1
            [id] => 201
            [catid] => 39
            [title_slug] => 201:facilities
            [cat_slug] => 39:facilities
        )

)

Temporary Solution:
Implementing the following condition resolves the issue but is not ideal:

if ($tag == 'zh-TW') {
    $lang_code = 'tw';
} else {
    $lang_code = substr($tag, 0, 2);
}

Any help or assistance would be wonderful.

When I used the universal module before, Flexicontent always get zh-CN items also when I needed to retrieve only zh-TW.

we need to use something like:

$site_languages = FLEXIUtilities::getLanguages();
$lang_code = $site_languages->{$tag}->sef;
